n-Heptane is a chemical compound with the formula C7H16, consisting of a chain of seven carbon atoms and 16 hydrogen atoms. It is a colorless, flammable liquid that belongs to the group of alkanes, which are the simplest and most common type of hydrocarbons. N-Heptane is widely used as a solvent in various industries, such as paints, coatings, adhesives, pharmaceuticals, and oil extraction. It is also used as a reference fuel to measure the octane rating of gasoline, as it has the lowest octane number of zero. This means that n-heptane burns more easily and causes engine knocking, which is a problem for gasoline engines. Therefore, gasoline is blended with other hydrocarbons that have higher octane numbers to prevent knocking and improve engine performance.

N-Heptane is mainly produced from the refining of crude oil, which is a complex mixture of different hydrocarbons. N-Heptane can be separated from crude oil by a process called fractional distillation, which involves heating the crude oil and collecting the different fractions that boil at different temperatures. N-Heptane is one of the components of the light naphtha fraction, which boils between 30°C and 200°C. N-Heptane can also be synthesized from other hydrocarbons, such as ethylene, propylene, and butane, by a process called oligomerization, which involves combining smaller molecules into larger ones.

The supply and demand of n-heptane are influenced by various factors, such as the price and availability of crude oil, the demand from downstream industries, the environmental regulations, and the geopolitical situations. The price of n-heptane is closely linked to the price of crude oil, as it is one of the main raw materials for its production. The price of crude oil is determined by the balance between the global supply and demand, as well as the market expectations and speculations. The supply of crude oil depends on the production capacity and output of the major oil-producing countries, such as Saudi Arabia, Russia, and the United States. The demand for crude oil depends on the economic growth and energy consumption of the major oil-consuming countries, such as China, India, and the European Union. The price of crude oil can also be affected by unexpected events, such as natural disasters, wars, and sanctions, that disrupt the normal production and transportation of oil.

The demand for n-heptane is driven by the demand from the downstream industries that use it as a solvent or a fuel additive. The demand for n-heptane can vary depending on the season, the region, and the industry. For example, the demand for n-heptane as a solvent for paints and coatings can increase in the summer, when the construction and renovation activities are more active. The demand for n-heptane as a solvent for oil extraction can increase in the winter, when the viscosity of the crude oil is higher and needs to be reduced for easier pumping. The demand for n-heptane can also differ across regions, depending on the local preferences and regulations for gasoline quality. For example, some countries, such as China and India, have stricter standards for gasoline octane rating, which require more n-heptane to be blended with gasoline to lower its octane number and reduce its emissions.

The supply and demand of n-heptane can also be influenced by the environmental regulations and policies that aim to reduce the greenhouse gas emissions and improve the air quality. These regulations and policies can affect the production and consumption of n-heptane in different ways. For example, some regulations, such as the Clean Air Act in the United States, can limit the amount of n-heptane that can be used as a solvent or a fuel additive, as it contributes to the formation of ozone and smog, which are harmful to human health and the environment. On the other hand, some policies, such as the Renewable Fuel Standard in the United States, can encourage the use of n-heptane as a solvent or a fuel additive, as it can help to increase the blending of biofuels, such as ethanol and biodiesel, with gasoline and diesel, which are more environmentally friendly.

The challenge of n-heptane supply is to balance the supply and demand of this important chemical compound in a volatile and uncertain market. The producers and consumers of n-heptane need to monitor the market trends and dynamics, and adjust their production and procurement strategies accordingly. The producers of n-heptane need to optimize their production capacity and output, and diversify their sources of raw materials and markets. The consumers of n-heptane need to secure their supply contracts and inventories, and explore alternative solvents and fuels. The governments and regulators need to provide clear and consistent policies and regulations, and foster cooperation and coordination among the stakeholders. The researchers and innovators need to develop new and improved technologies and processes, and discover new and better applications and uses of n-heptane.

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.
