According to the latest global polyethylene pipe research report released by Freedonia group, China’s total demand for polyethylene pipe in 2019 was 4.2 million tons, accounting for 33% of global demand and 59% of regional sales, which is the largest market in the world so far.

The research report points out that China’s agriculture, construction, manufacturing, oil and gas and public utilities have a large volume, and plastic pipelines are needed in these fields. In addition, China’s diversified processing and manufacturing industries, including chemical industry, food processing, primary metals, pulp, paper and textiles, also need plastic pipes.

The scale of China’s construction industry is almost four times that of the United States, and the sales volume of polyethylene pipes is about three times that of the United States. China’s infrastructure investment continues to make great progress, and the proportion of product sales in the population is almost twice the global average.

The report predicts that by 2024, the global demand for polyethylene pipes will increase at an annual rate of 3.7% to 15.3 million metric tons, which is due to the increasing use of polyethylene pipes in all markets. Among them, HDPE pipes will also maintain healthy growth because they are more popular than other materials in water treatment and sewer applications.

Demand will be driven by polyethylene’s versatility, easy processability, low cost, and recyclability; by new ethylene feedstocks; and by improved polymerization catalyst technologies.

World demand to rise 4.0% annually through 2018

Global demand for polyethylene resins will rise 4.0 percent per year to 99.6 million metric tons in 2018, valued at $164 billion. Gains will match overall world economic growth, fueled by an acceleration in consumer spending and manufacturing activity. Polyethylene will continue to be the most widely used plastic resin in the world, benefiting from its versatility, easy processability, low cost, and recyclability. The development of ethylene feedstocks from new sources such as shale gas, coal, and biobased materials will also give polyethylene a price advantage over other plastic resins. Moreover, continually improving polymerization catalyst technologies will enhance the performance, customization, and yield of polyethylene resins. Further increases will be limited, however, by the highly commoditized and mature position of polyethylene. Additionally, major polyethylene applications such as plastic bags have increasingly become subject to environmental regulations and bans.

Asia/Pacific region to remain largest, fastest growing market

The Asia/Pacific region will continue to be the largest and fastest growing polyethylene market through 2018, fueled by strong growth in China, which alone accounted for nearly one-quarter of global demand in 2013. India and Vietnam will also be among the world’s most rapidly expanding markets. However, advances in most emerging Asian countries will rise at a slower pace than during the 2008-2013 period. On the other hand, North America will see a significant improvement in polyethylene demand, while the markets in Western Europe and Japan will rebound from recent declines.

LLDPE to gain market share over LDPE

View Post

HDPE is the most widely used of the three polyethylene resins, accounting for just under half of total demand in 2013. Above average growth is expected for HDPE through 2018, driven by its rising use in construction products such as pipe and the increasing popularity of blow-molded HDPE containers in emerging market countries. LLDPE will continue to gain market share over LDPE going forward, as LLDPE is the primary beneficiary of metallocene catalyst technology, which improves resin performance. Packaging will remain the largest outlet for polyethylene, accounting for a majority of demand in 2018. The resin’s favorable sealing, stiffness, moisture barrier, and clarity properties make it an indispensible material in the packaging industry. Film accounts for about half of global polyethylene demand and tends to comprise a particularly large portion of the market in developing countries.

Pentane: What Is It and How Do We Use It?

Pentane is an organic substance. It can be used to describe any 3 structural isomers or their combination. But, according to IUPAC, this phrase is exclusive to the n-pentane isomer. We also differentiate neopentane or dimethylpropane as well as isopentane or methylbutane.

​Pentanes are commonly used for fuels, but they can also be utilized as solvents in labs. The substance carries similar traits as hexanes and butanes.

Pentanes are generally used for insulation products. However, you can utilize them in so many different ways. Whether you’re relying on n-pentane, cyclopentane, or iso-pentane, each one of the chemical compounds can serve as the main ingredient for various products. In this article, we will discuss pentane, in general, as well as its potential application.

How do we get pentanes?

Pentanes are saturated hydrocarbons. Each one of them has five carbon atoms. We get n-pentane and iso-pentane naturally from crude oil.

They are made during gas production as natural byproducts. On the other hand, cyclopentane is found in naphtha or crude petrol. It is a molecule in the shape of a ring, and it is very popular across several industries. Oil refineries create cyclopentane through the cracking process.

Naphtha has variable quantities of pentanes. It all depends on its origin, the acquiring process, and the construction of the refinery.

They are the first hydrocarbons to become liquids at room temperature. Out of these substances, iso-pentane has the lowest boiling point.

The substance will boil at 29 degrees Celsius compared to n-pentane, which boils at 35 degrees, and cyclopentane that has a boiling point of 49 degrees Celsius. Due to these differences between pentanes’ boiling points, you are able to separate the substances.

What are the main differences between pentane types?

As you can presume, there are some major differences between these substances aside from their boiling points. Companies use them in numerous ways, and they have some major advantages over other crude oil derivatives. What’s even better is that you can mix these chemicals. This is how we get pentane blends, each with its unique set of traits.
How do you use n-pentane?

Generally speaking, n-pentane and iso-pentane are somewhat similar substances. They react in a similar fashion when you use them for different products. Usually, n-pentane is utilized as a refrigeration or air conditioning substance, effectively replacing things such as fluorinated hydrocarbons and ammonia. Here are some of its potential uses:

Refrigerant R601
Very non-polar solvent
Process medium for polyethylene

How do you use iso-pentane?
​A great thing about iso-pentane is that it almost cannot be dissolved in water. Furthermore, it has very soluble when used with other organic solvents like ethers, esters, paraffins, chlorinated hydrocarbons, aromatics, etc. Also, the substance has unlimited miscibility. This gives iso-pentane high versatility. Companies try to utilize their characteristics as much as possible for various products.

Non-polar solvent with high volatility
Personal care products like shower gels
It can be used as a process medium for polypropylene and polyethylene
Working medium in geothermal plants
How do you use cyclopentane?
While the previous two substances may have certain similarities, cyclopentane is completely different from both of them. It is not that popular as a solvent, nor is it used as an ingredient for other chemicals. But, it is a very common substance for insulation products.

It can be used for solvents and insulation board
Cyclopentane is great for refrigeration and refrigeration logistics
Blowing agent for polyurethane foams
Fine chemicals
Different ways pentane is used across various industries
Pentanes are very flexible products. Each one of these subtypes has a wide range of applications. Here is how different industries rely on them for their day-to-day business:

Geothermal plants
Pentanes are very important for renewable energy creation. Geothermal plants use iso-pentane as a medium during their crucial heating processes. Plants extract heat from the ground and use it for heating energy; iso-pentane is there to facilitate the process.

Cooling substance
Companies are also using pentanes as cooling agents. Whether we’re talking about iso-pentane or n-pentane, both of these chemical compounds can be utilized as cooling substances for air conditioning appliances and refrigeration systems. They are a much better alternative to fluorinated hydrocarbons and ammonia.

Cosmetics and care products
Pentanes are also very famous for their cosmetic industry application. They are a crucial ingredient for products like shower gels and shaving creams. Furthermore, these substances are the main reasons why personal care items have their specific, creamy texture.

Companies use pentanes for the production of polypropylene and polyethylene
Among others, companies use these substances to create polyethylene and polypropylene. Polyethylene is the most popular plastic substance in the world. Nowadays, plants use ethylene to create these products. During its gas phase, liquid iso-pentane will be added to the gas stream. The substance works as a specific cooler. Once it is condensed, you can reuse it. We make polypropylene in a similar way as polyethylene, and once again, iso-pentane is added during the gas phase to facilitate the process.

Insulation materials
Pentanes are commonly used for the creation of polystyrene and polyurethane insulation boards. Companies use them as blowing agents during polyisocyanurate and polyurethane formulation. Insulation materials are very important for the food industry and household appliances. You can use them for freezers, refrigerators, and cold storage. They are also crucial for constructions and various others industries. For example, you can use them for building, pipes, and other materials.

Cyclopentane is great for long-lasting insulation. It is especially good for smaller surfaces and spaces due to its ability to stay within polyurethane and polyisocyanurate foam for a long time, even after foaming. The pentane can be used for cooling devices and thin insulation panels.
​
Packaging material
Among others, pentanes are important for the creation of packaging material. Once again, pentane is utilized as a blowing agent. We use it to create extruded polystyrene, which is later on utilized for packaging chips.

Pentanes have numerous applications. As long as you use them with care, you should be able to create some incredible materials that can be utilized in various industries.

The Denizli Tosunlar ORC geothermal power plant in Turkey received the Top Plant award in the Renewable energy project domain. Italian company Exergy S.p.A. built it for its client Akça Enerji in 2015.

The Power Magazine awarded the Denizli Tosunlar ORC geothermal plant as a part of its “Power Awards” competition, and announced its decision in the December issue of the magazine. A jury comprised of the U.S.-based magazine’s editors selected this 4 MW facility as the best in the Renewable projects category. Other categories include Natural gas-fired, Coal-fired, and Nuclear projects. The winner in each of the category was chosen for demonstrating an innovative design and engineering upgrades, for producing power more reliably or economically than comparable plants or demonstrating a new generation or environmental controls technology.

The Turkish branch of Exergy built this organic Rankine cycle (ORC) geothermal plant for its client Akça Enerji. It is the world’s first geothermal power plant with two-pressure-level cycle on a single-disk turbine. The Denizli Tosunlar has been operational since June 2015. It has already received an award in February 2016 – the key European Geothermal Innovation Award from the European Geothermal Energy Council for innovation demonstrated in this geothermal plant.

“We are very proud to have received a second award this year for our Denizli Tosunlar power plant. This repeated recognition gives evidence of the technological breakthrough this plant represents and rewards the commitment and the effort that Exergy put into R&D activities to keep us at the forefront of innovation by achieving new, smarter and more efficient applications of our technology. We are constantly working on further advances in technology for the ORC market in order continue to evolve and sustain clean power generation,” said Claudio Spadacini, chief executive officer of Exergy, which appear to have achieved considerable success in Turkey in the last several years.

Organic Rankine cycle usually uses low boiling point organic working fluids, such as atmospheric ethane, n-Pentane and Isopentane, etc. the medium and low-temperature geothermal fluid is used to exchange heat with low boiling point organic working fluid to make the latter evaporate and generate steam with high pressure to drive steam turbine to do power generation.

Organic – pentane, propane, ammonia and coolants

A blowing agent is a substance which is capable of producing a cellular structure via a foaming process in a variety of materials that undergo hardening or phase transition, such as polymers, plastics, and metals. They are typically applied when the blown material is in a liquid stage. The cellular structure in a matrix reduces density, increasing thermal and acoustic insulation, while increasing relative stiffness of the original polymer.

Blowing agents are additives used in the manufacture of foamed plastics, which have the advantage of lightness, contribute to material and cost savings, and are distinguished by the fact that they are thermally insulating. Blowing agents usually create fine and regular cellular structures during polymer processing.

Blowing agent plays a fundamental role in the production of polystyrene (PS), polyurethane (PU) and polyisocyanurate (PIR) insulations foam. A small quantity of blowing agent indirectly provides important performance characteristics to these foams as great thermal insulation properties.

The global warming potential (GWP) of the blowing agents used to manufacture insulation products like polyiso insulation can be an important consideration when assessing each product’s environmental impacts. Blowing agents function to increase the final thermal resistance or R-value of foam insulation, and also help to facilitate the manufacturing or foaming process.  

Manufacturers of laminated insulation products in North America use #pentane or #pentane #blends in their production processes. Pentane is a hydrocarbon with zero ozone depletion potential (ODP) and low-GWP. Manufacturers have utilized pentane technologies in product formulations for over 20 years.

Pentane has a GWP value of less than 10, which means that insulation products produced and sold in North America comply with climate regulations that limit the manufacture or installation of products produced with higher-GWP substances (including products manufactured with hydrofluorocarbons (HFCs) or blends thereof). Therefore, architects and contractors can continue to specify insulation products manufactured by PIMA members with confidence in both the industry’s performance and environmental scorecard.

Blowing agents can allow the polymer processor to achieve weight reduction and use less raw materials by introducing a finely controlled cell structure within the polymer. With the endothermic blowing agents, as part of their functionality, they will absorb heat energy from their surroundings.

Foam blowing agents encompass a wide variety of applications including refrigerators, buildings, automobiles, furniture, packaging, and many more. The blowing agent is used to create a cellular structure from liquid plastic resin, and in the case of foam used for insulation it functions as an insulating component of the foam.

When it comes to blowing agents, a controlled foam structure makes your production process go a lot smoother

Not only do blowing agents expand up to 60 times in volume, they also provide:

• highly controlled foaming
• closed, uniform cell structure
• guards against water penetration
• create internal pressure to combat shrinkage.

Blowing agent plays a fundamental role in the production of polystyrene (PS), polyurethane (PU) and polyisocyanurate (PIR) insulations foam. A small quantity of blowing agent indirectly provides important performance characteristics to these foams as great thermal insulation properties.

What is EPS

Polystyrene is one of the most widely used kinds of plastic. It is a polymer made from the monomer styrene, a liquid hydrocarbon that is commercially manufactured from petroleum by the chemical industry. Polystyrene is a thermoplastic substance, it melts if heated and becomes solid again when cool.

Polystyrene is most commonly found in three forms. Rigid Polystyrene (PS), Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS).

Rigid polystyrene has many applications including disposable cutlery, cd cases, video/casette casings, components for plastic model toys as well as some margarine and yoghurt containers.  Extruded polystyrene foam has good insulating properties making it important as a non-structural construction material.  XPS is sold under the trademark Styrofoam by Dow Chemical, however this term is often used informally for other foamed polystyrene products.

How to produce foam?

Expandable Polystyrene / EPS:

This is PS Foam that uses Pentane gas (C5H12) as the blowing agent. During the material production process called “Polymerisation” the polystyrene resin granules impregnated with the blowing agent. EPS production processes begin in the pre-expansion process where the EPS bead will expand by the heat of steam usually 50 times in volume. The next step in the process is moulding process where expanded foam bead will be heated again with steam then they expand further until they fuse together, forming as foam products.

There are mainly 2 types of EPS moulding machines;

• Shape moulding machine that produce various shapes of foam products according to the molds such as icebox, helmet and packaging foam.
• Block moulding machine that produce block foam and sheet foam Expanded EPS foam bead contains 98% air per volume, only 2% is plastic. This make EPS foam very light weight, has low thermal conductivity because air is the best insulation, high compressive strength and excellent shock absorption. These properties make EPS to be ideal material for packaging and construction.

Polystyrene Paper (PSP):

This is a PS Foam which is produced by extruding process as another plastic. Production process start when put polystyrene resin pellets into the extruder that heated by electric. Foaming process occur at the end of extruder where the blowing agent, butane (C4H10) gas react with the melt plastic then become foam. The melted polystyrene foam is then extended as sheet then rolled as paper roll, that is why it is commonly known as “Polystyrene Paper”. The polystyrene foam sheet or polystyrene paper can be produced as many shape according to the mould by thermal forming process such as food tray, cups, bow, and food box.

There’s no any CFC’s in PS foam

Both EPS and PSP contain 95 -98 % air another 2-5% is polystyrene which is pure hydrocarbon. CFC’s is Chlorofluorocarbons which is totally different in its chemical structure from polystyrene. CFC’s has very low blowing point and uneasy to be maintained in EPS beads. Therefore, EPS Foam never use CFC’s at any stage of its production. The blowing agent used since EPS Foam was first introduced in 1952 by BASF  is Pentane gas which, does not contain any chlorine atoms as CFC’s. PSP Foam in the beginning used CFC’s as blowing agent. In the past two decades CFC’s are gradually phased out from plastics and refrigerator industries. PSP moulders in Thailand already use Butane (C4H10) as the blowing agent since the last 15 years. Butane gas is the gas that we use at home for cooking. The blowing agents that use in producing PS Foam are Pentane and Butane, which are pure hydrocarbon as polystyrene. They belong to the same chemical family, the paraffin series as methane, ethane, and propane gas.

How to manage the EPS foam waste

Apart from recycling by melting and compacting, there are many ways to manage the EPS waste as the followings:

• Crush in to small particle and mix with soil. Foam waste will improve ventilation in the soil, organic substances in the soil will become easier the humus.
• Mixing the crushed bead with cement to reduce the weight and increase insulation properties.
• Combustion at 1000 C with sufficient air supplies in to generate heat. Burning EPS require no any additional fuel, in fact EPS can replace the fuel normally required for combustion, l kg of EPS saves 1 kg = 1.2 – 1.4 Litre of fuel oil.

The Recycling of PS:

Since both EPS and PSP Foam are made of Polystyrene, which is thermoplastic, so that it will become again a polystyrene plastic when recycled. AMEPS members recycle both EPS and PSP Foam by first crushing into small particle then melting or compacting it. Melting can be done by heated roller, disk or screw extruders, where the regrind scraps is heated usually by electrical power for some time above the melting temperature. Compacting can be done by rotary compactors where pressure and frictional force create heat below melting temperature to soften the regrind scraps for only few seconds. This method also called “agglomeration”.PS pallet from recycled foam will be produced in various kinds of plastic products e.g. video and tape cassette and ruler. The other way to reuse EPS Foam is to mix the regrind beads with the new expanded bead for re-production in moulding process.

Pentane as Blowing Agent in PUR foam and PU Market in China

An integrated thermal recovery process using a solvent of a pentane or hexane or both as an additive to, or sole component of, a gravity-dominated process for recovering bitumen or heavy oil from a reservoir. A pentane-hexane specific solvent fraction is extracted at surface from a diluent stream. That pentane-hexane solvent fraction is then injected into the reservoir as part of a gravity-dominated recovery process within the reservoir, and when that solvent fraction is subsequently produced as part of the oil or bitumen blend, it is allowed to remain within the blend to enhance the subsequent blend treating and transportation steps. Meanwhile, the remainder of the diluent from which the solvent stream had been extracted is utilized at surface as a blending stream to serve as an aid in treating of produced fluids and also to serve as a means of rendering the bitumen or heavy oil stream pipelineable.

The upstream of pentane industry chain is the by-product from cracking of natural gas condensate, oil field light hydrocarbon and light naphtha ethylene plant, and the main product of C5 is cyclopentadiene. The downstream is the application market, mainly focusing on polyurethane foaming agent, EPS foaming agent, linear low density polyethylene solvent and other fields.
Due to the different structures and properties of n-pentane, isopentane and cyclopentane, their application fields are quite different. N-pentane can be isomerized to produce isopentane, and can also be used as foaming agent. It can also be used in low temperature thermometer, artificial ice, anesthetic, and pentanol synthesis. Isopentane is an important admixture to improve octane number of gasoline, and is also an important raw material for isoprene production. It can also be dehydrogenated, chlorinated, and hydrolyzed to produce isopentene, isoprene, and isopentanol, which are organically synthesized Cyclopentane is mainly used in organic synthesis and intermediate of fine chemicals, and its market demand is low at present.

According to the comprehensive market research and investment analysis report of pentane industry in China 2020-2024 issued by China Industrial Research Center It shows that the pentane terminal market is home appliances, building materials, packaging and other industries. In recent years, the above three industries present different development trends. Among them, due to the rapid development of package delivery industry, the demand of packaging industry is strong; however, the development of home appliances and construction industry is relatively slow, and the demand for pentane is declining. In general, in recent years, the pentane demand presents a fluctuating growth state, and the growth rate is slow. In 2019, the pentane industry demand in China is 273000 tons, and the market scale reaches 1.83 billion yuan, of which isopentane is the largest, accounting for 45%; followed by n-pentane, accounting for 39%; cyclopentane and other products, accounting for 16%.
The raw materials for pentane production are mainly in the hands of petrochemical refineries. The representative enterprises are PetroChina, Sinopec, etc. with their own raw material advantages, they have a high market share. Pentane production enterprises need to purchase raw materials from large petrochemical refineries for processing, so considering transportation conditions and costs, most pentane production enterprises are located near large petrochemical refineries, mainly in Shandong Province, and East China currently accounts for more than 50% of the production capacity. At present, the leading enterprise of pentane production in China is Junyuan Petroleum Group.
