On February 21, China Nitrogen Fertilizer Industry Association held the 2022 China methanol industry conference in Hangzhou to summarize the work of methanol industry in 2021 and analyze and discuss the methanol market and development trend in 2022. On the same day, China nitrogen fertilizer industry association commended the top 20 national methanol production enterprises in 2021 and advanced energy-saving enterprises in the methanol industry.
Gu zongqin, President of China nitrogenous fertilizer industry association, pointed out at the meeting that at present, the development of methanol is facing positive factors such as the recovery of the world economy, the steady rise of international oil prices, the continuous increase of downstream product consumption and the easing of overcapacity. However, we should also see the adverse factors and still face many challenges.
Gu zongqin believes that with the economic recovery of various countries, the demand for chemical products will inevitably increase, which will further drive the recovery of methanol prices. At the same time, the recovery of international oil prices will drive the rise of foreign methanol prices, help to improve the competitiveness of domestic coal based methanol production, and will also strongly support domestic prices.

The consumption data in recent ten years show that the growth of methanol consumption in China is roughly more than 10% every year. Gu zongqin predicted that the growth of methanol consumption in the next few years will also maintain the previous trend for three reasons: first, the pilot work of methanol vehicles will continue; Secondly, alcohol based fuels for boilers and stoves as clean substitutes for coal can greatly improve air quality; Third, the consumption of methanol downstream products will continue to grow, and coal to olefin is still the main direction of the development of the industry. In addition, new downstream products are still being researched and developed, such as toluene methanol methylation to produce p-xylene.
However, China’s methanol industry still faces a series of challenges. Gu zongqin said that the task of removing production capacity this year is still arduous, the development of upstream and downstream is still unbalanced, the pressure on safety and environmental protection continues to escalate, and the price of raw materials is facing rising pressure.
Although the methanol units that have stopped production for two consecutive years are more than 9 million tons / year, involving more than 120 production enterprises. However, Gu zongqin pointed out that with the improvement of the market, some old production capacity with high energy consumption, high emission and backward devices may be driven. In addition, a large number of new units are still put into operation and technological transformation and capacity expansion every year, resulting in a high rate of increase in methanol production capacity, and the task of eliminating backward production capacity is very arduous.
The pressure of safety and environmental protection in methanol industry will continue to escalate. Gu zongqin said that as a chemical enterprise with high energy consumption and high emission, methanol enterprises are facing great pressure from many aspects, such as the significant rise of environmental protection treatment costs and power costs, as well as the shutdown and production restriction according to the emission reduction requirements during the emergency response period.
In order to realize the high-quality development of methanol industry, Gu zongqin proposed to do a good job in five aspects this year: continue to do a good job in reducing production capacity; Accelerate the adjustment of product structure, expand the industrial chain, and improve product added value and market competitiveness; Accelerate the popularization and application of advanced technology and promote the technological progress of the industry; Further improve the level of energy conservation and emission reduction in the industry; Actively carry out international exchanges and cooperation.
Junyuan Petroleum Group has made remarkable achievements in tapping energy-saving potential, deepening energy conservation and emission reduction and improving energy utilization, Won the title of “advanced enterprise in energy conservation in methanol industry in 2021”.

Pentane is the main foam blowing agent used in the production of polystyrene foam and other foams. Typically, blends of n-, iso- and Cyclopentane are used for this purpose.
●Manufactured with aluminum foil facing or corrugated metal sheet on both or either sides to be used as thermal insulation sandwich panel.
●n-Pentane is used as blowing agent; Chlorofluorocarbons (CFC’s) haven’t been used in manufacturing of this product.
●n-Pentane blowing agent has ZERO ODP (Ozone Depletion Potential) and low GWP (Global Warming Potential)

Sandwich panels, built with a polyurethane panel adhered by both side to a metallic cover, are an optimal solution for all kind of enclosures, decks, roof waterproofing and sheds. These PU panels are widely used in building construction for facade cladding or roof covers as well as for cold stores as thermal and acoustic insulation. For many years PU industry uses n-Pentane as blowing agent for the manufacturing of the sandwich panel. n-Pentane is a hydrocarbon rated by the CLP regulation as a flammable liquid of category 1, current global situation showing shortage and delays with raw materials, having bigger safety stock may represent a competitive advantage ensuring customer commitment, lead time and quality.

Pentane is a flammable blowing agent that offgases from product, yet EPA document 540/3-90-020 states that 85% of the pentane is emitted within 48 hours of the start of the expansion process in the factory, with the remainder emitted over time. Considering manufacturer’s curing process, the vast majority of the 15% remainder of the pentane should be emitted prior to shipment, with the remainder being emitted during subsequent shipment, storage, and usage. Cyclopentane is a liquid below 120°F and isopentane liquefies at 82°F; n-pentane remains in a gaseous state above 97°F.

Volatile Organic Compounds (VOC):
Pentane: EPS manufacturing uses beads as a raw material, and EPS beads typically contain 4%-7% pentane by weight, which is defined as a VOC by the EPA. EPA document 540/3-90-020 states that 85% of the pentane contained in the EPS bead is emitted within 48 hours starting with the expansion process (which occurs within the manufacturing facility). The remaining pentane is released over time, there is likely negligible pentane content in the foam by the time of installation.
Styrene: Styrene is considered a VOC by the EPA. While Certificates of Analysis from bead suppliers typically do not state a styrene monomer content of EPS bead, several EPS bead suppliers have established that EPS beads typically contain styrene monomer, 900 to 1000 ppm by weight. After pre-expansion and expansion of beads, concentration should be considerably reduced.

What is Expanded Polystyrene (EPS)?
Expanded PolyStyrene (EPS) is a white foam plastic material produced from solid beads of polystyrene. It is primarily used for packaging, insulation, etc. It is a closed-cell, rigid foam material produced from:
Styrene – which forms the cellular structure
Pentane – which is used as a blowing agent
Polystyrene is produced from crude oil refinery product styrene. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. Polystyrene granulate is prefoamed at temperatures above 90°C. Both styrene and pentane are hydrocarbon compounds and are obtained from petroleum and natural gas byproducts.
EPS is very lightweight with very low thermal conductivity, low moisture absorption and excellent cushioning properties. One of the serious limitations of polystyrene foam is its rather low maximum operating temperature ~80°C. Its physical properties do not change within its service temperature range (i.e. up to 167°F/75°C) for long-term temperature exposure.
Its chemical resistance is nearly equivalent to the material upon which it is based – polystyrene.
EPS is 98% air and it is recyclable.

What is the chemical name of Pentane?
General pentane (hereafter, pentane) is a colorless, volatile and flammable liquid with a sweet or gasoline-like odor. Pentane consists of three isomers: n-Pentane (the most important isomer), isopentane, and neopentane. n-Pentane is a constituent of crude oil and a component of the condensate from natural gas production.

Is pentane a blowing agent?
Blowing agent Pentane is a hydrocarbon solvent coming directly from the natural gas and crude oil. Pentane as blowing agent in (PUR) insulation foam : N-Pentane (CAS : 78-78-4).

What is the average cost of foam insulation?
The national average cost to fully insulate a home with spray foam is $10,000 to $30,000. Most homeowners spend around $20,000 on a mixture of open and closed cell insulation 6 inches thick in an existing 2,000 sq.ft. home. This project’s low cost is around $6,000 for 4 inches of open cell foam covering the attic floor.
