Solvent Vegetable oils are widely used in food, chemical, pharmaceutical, and cosmetic industries. They are obtained from various plant sources, such as soybean, rapeseed, peanut, corn, olive, etc. The extraction of vegetable oils is a crucial step in the production process, as it affects the yield, quality, and cost of the final products. There are different methods for extracting vegetable oils, such as mechanical pressing, solvent extraction, supercritical fluid extraction, etc. Among them, solvent extraction is the most common and efficient one, as it can extract more oil from the plant materials, especially those with low oil content or high oil viscosity. However, solvent extraction also poses some challenges, such as the choice of the solvent, the recovery of the solvent, the environmental impact of the solvent, etc. Hexane is a straight-chain alkane with six carbon atoms and the molecular formula C6H14. It is a colorless, odorless, and highly volatile liquid, with a boiling point of about 69 °C. It is widely used as a cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvent. Hexane is also the most commonly used solvent for vegetable oil extraction, as it has a high affinity for oil and a low affinity for water. Hexane can dissolve up to 70% of oil from the plant materials, leaving behind a solid residue called oil cake, which can be used as animal feed or fertilizer. However, hexane is not a pure substance, but a mixture of different isomers and impurities, such as pentane, heptane, benzene, sulfur, lead, arsenic, etc. These impurities can affect the quality and safety of the extracted oil, as well as the health and environment of the workers and consumers. Therefore, the purity and composition of hexane are important factors to consider when choosing a solvent for vegetable oil extraction. n-Hexane is the most stable and abundant isomer of hexane, with a boiling point of about 68 °C. It is a refined grade of hexane, which contains at least 60% of n-hexane and less than 40% of other isomers and impurities. n-Hexane has many advantages over other grades of hexane, such as: – Lower solvent loss: n-Hexane has a narrower distillation range (2-4 °C) than other grades of hexane (15 °C or more), which means it has less light and heavy fractions that can easily evaporate or remain in the oil cake. Therefore, n-Hexane can reduce the solvent loss per ton of oil extracted, which can save cost and energy. – Higher extraction capacity: n-Hexane is the most effective solvent for oil extraction, as it has the highest solubility and the lowest viscosity among the hexane isomers. Therefore, n-Hexane can extract more oil from the plant materials, especially those with high oil content or low oil viscosity, such as rapeseed, sunflower, etc. – Lower toxicity: n-Hexane has a lower content of benzene, sulfur, lead, arsenic, and other harmful impurities than other grades of hexane. These impurities can cause acute or chronic poisoning, cancer, or neurological damage to the workers and consumers who are exposed to them. Therefore, n-Hexane can reduce the health risks and the regulatory requirements associated with the solvent extraction process. – Lower corrosion: n-Hexane has a lower content of sulfur and other corrosive impurities than other grades of hexane. These impurities can react with the metal equipment and cause rust, wear, or leakage. Therefore, n-Hexane can extend the service life and the maintenance cycle of the extraction equipment, which can save cost and time. – Lower environmental impact: n-Hexane has a lower content of volatile organic compounds (VOCs) and other pollutants than other grades of hexane. These pollutants can cause air pollution, greenhouse effect, ozone depletion, or acid rain when they are released into the atmosphere. Therefore, n-Hexane can reduce the environmental impact and the emission control measures required for the solvent extraction process. In conclusion, n-Hexane is a superior solvent for vegetable oil extraction, as it can offer many benefits, such as lower solvent loss, higher extraction capacity, lower toxicity, lower corrosion, and lower environmental impact. n-Hexane can improve the efficiency, quality, safety, and sustainability of the vegetable oil production process, and create more value for the producers and consumers.

Flammable liquids are substances that can catch fire easily when exposed to heat, sparks or flames. They are widely used in various industries, such as chemical, pharmaceutical, oil and gas, and transportation. However, transporting flammable liquids poses significant challenges and risks, as they may cause fire, explosion, leakage, or environmental pollution if not handled properly. Therefore, it is essential to choose the appropriate containers and methods for transporting flammable liquids safely and efficiently.

In this article, we will focus on two common types of flammable liquids: butane and isobutane. Butane and isobutane are both liquid hydrocarbons, belonging to the third class of dangerous goods². They are mainly used as fuels, refrigerants, propellants, and solvents. They have similar chemical properties, but different molecular structures. Butane has a straight-chain structure, while isobutane has a branched-chain structure. This difference affects their physical properties, such as boiling point, vapor pressure, and density.

We will introduce the characteristics and applications of butane and isobutane, and explain how they can be transported using ISOTank containers, which are specially designed for carrying liquid or gas cargoes. We will also compare the advantages and disadvantages of different types of ISOTank containers, and provide some tips and suggestions for choosing and using them.

What are Butane and Isobutane?

Butane and isobutane are both colorless and odorless liquids at room temperature and atmospheric pressure. They have low viscosity and high volatility, meaning that they can easily flow and evaporate. They are also highly flammable and explosive, meaning that they can ignite and explode when mixed with air in certain proportions. They have low toxicity and low corrosivity, meaning that they have little harmful effects on human health and metal materials.

Butane and isobutane have many industrial and domestic applications, such as:

• As fuels for cooking, heating, and camping. They are often stored in pressurized cylinders or cartridges, and burned in stoves, heaters, or lanterns.
• As refrigerants for cooling and freezing. They are often used in refrigerators, freezers, air conditioners, and heat pumps, as they have good thermodynamic properties and low environmental impact.
• As propellants for aerosols and foams. They are often used in spray cans, such as hairsprays, deodorants, paints, and whipped creams, as they can create high pressure and fine mist.
• As solvents for extraction and purification. They are often used in chemical processes, such as oil refining, natural gas processing, and pharmaceutical manufacturing, as they can dissolve and separate various substances.

How to Transport Butane and Isobutane?

Butane and isobutane can be transported by various modes, such as pipelines, trucks, trains, ships, and planes. However, each mode has its own limitations and challenges, such as capacity, cost, safety, and environmental impact. Therefore, it is important to choose the most suitable mode for different situations and destinations.

One of the most common and convenient modes for transporting butane and isobutane is using ISOTank containers, which are standardized and modularized containers that can carry liquid or gas cargoes. ISOTank containers are made of stainless steel, and have a cylindrical tank inside a rectangular frame. They have various valves, fittings, and accessories, such as heating, insulation, pressure relief, and inert gas systems, to ensure the safety and quality of the cargoes. They can be easily loaded and unloaded, and transferred between different modes, such as trucks, trains, ships, and planes, without changing the containers.

ISOTank containers are classified into different types according to the International Maritime Dangerous Goods (IMDG) Code, which regulates the transportation of dangerous goods by sea. The types of ISOTank containers are based on the design pressure, the minimum and maximum temperatures, and the test pressure of the containers. The main types of ISOTank containers are:

• IMO 1: for transporting substances with a vapor pressure of less than 1.5 bar at 50°C, and a test pressure of at least 6 bar.
• IMO 2: for transporting substances with a vapor pressure of less than 4 bar at 50°C, and a test pressure of at least 4 bar.
• IMO 5: for transporting refrigerated liquefied gases, such as ammonia, carbon dioxide, and nitrous oxide, with a test pressure of at least 1.8 bar.
• IMO 7: for transporting cryogenic liquefied gases, such as liquid nitrogen, oxygen, and helium, with a test pressure of at least 10 bar.

According to the IMDG Code, butane and isobutane should be transported using IMO 1 or IMO 2 ISOTank containers, as they have a vapor pressure of about 2.3 bar and 3.1 bar at 50°C, respectively³. These types of ISOTank containers have the following features:

• The tank is made of stainless steel, which can resist the corrosion and leakage of butane and isobutane.
• The tank has a steam or electric heating system, which can maintain the suitable temperature and pressure of butane and isobutane.
• The tank has an inert gas protection system, which can prevent the self-ignition or explosion of butane and isobutane.
• The tank has a pressure relief system, which can avoid the overpressure or vacuum of butane and isobutane.
• The tank has a protective and lifting frame, which can facilitate the multimodal transportation of butane and isobutane.

n-Pentane, Isopentane and Cyclopentane are all saturated hydrocarbons that have five carbon atoms. They have different molecular structures and physical properties, which make them suitable for different uses. Some of the common applications for these Pentane isomers are:

• Blowing agents for insulation materials: Pentanes are the foaming agent of choice for producing Polyurethane (PU) and Polystyrene (PS) insulation boards. They have a high performance and sustainability, as they do not deplete the ozone layer or contribute to global warming. Cyclopentane has the best insulating effect, while n-Pentane and Isopentane have more stable and finer foam cells².
• Refrigerants: n-Pentane can be used as a refrigerant in air conditioning or refrigeration systems, as an alternative to ammonia or fluorinated hydrocarbons. It has a low boiling point and a high latent heat of vaporization, which means it can absorb a lot of heat when it changes from liquid to gas¹.
• Non-polar solvents: Pentanes are almost insoluble in water, but show very good solubility or unlimited miscibility with many organic solvents such as paraffins, ethers, esters, aromatics or chlorinated hydrocarbons. They are also very volatile, which means they evaporate quickly and leave no residue. Therefore, they are suitable for cleaning in the aerospace, automobile, electronic, and defense manufacturing industries¹⁵.
• Process media for polyethylene and polypropylene: Pentanes can be used as process media for the production of polyethylene (PE, LLDPE) and polypropylene (PP), which are widely used plastics. Pentanes help to control the molecular weight, branching and crystallinity of the polymers, which affect their mechanical and thermal properties¹.

These are some of the main applications for n-Pentane, Isopentane and Cyclopentane. I hope this overview is helpful for you.
