Container Flexi Tank

Applicable product

Flexitank is mainly used to transport various non-hazardous liquid, main materials are Polypropylene PP woven cloth and multilayer food-grade polyethylene PE plastic film.It can be installed in 20ft container, high capacity and easily operated, can replace expensive tank, barrels and other traditional packages. Thus dramatically reduce the cost of loading and discharging, package, transportation and materials management etc.

Products Intro


LPG Tank

What is LPG?

Liquefied petroleum gas (LPG) is often mistaken for propane. In fact, LPG is a mixture of oil and natural gas at the appropriate pressure and is present at room temperature. In the United States and Canada, the mixing of these two substances is generally considered to be mainly composed of propane, while in many European countries the LPG has a propane content of only 50% or less.

LPG is one of the petroleum products, is from the oil and gas field mining, refineries and ethylene plant in the production of a colorless, volatile gas, mainly used in automotive, urban gas, nonferrous metal smelting and metal cutting and other industries.

What is the difference between LPG CNG and LNG?

LPG is liquefied petroleum gas, CNG is compressed natural gas, LNG is liquefied natural gas.

The main component of LPG is propane, natural gas is compressed to 20MPa to form high-pressure natural gas called compressed natural gas (CNG); natural gas through ultra-low temperature to -162 ℃ formation of liquid natural gas called liquefied natural gas (LNG).

Natural gas is the main component of methane (CH4), only a small amount of CO 2, H2S, N 2, He and other gases, flammable and explosive, full combustion, no carbon black and impurities, known as “green fuel.” The critical gas pressure is 161795; the critical temperature is – 74. 18 ℃; the critical pressure is 5.26 M Pa; the boiling temperature is – 161152 ℃; the gas density is 01716 7 kg / m 3 in the standard state; 01426 kg / L. Vehicle CN G is the raw material gas by dehydration, desulfurization after pressurized filling of the gas, the quality requirements should meet the national standard.As a result of strict control of the harmful substances H2S and total sulfur content, so with the traditional fuel gasoline , Compared to diesel, its combustion after the pollution greatly reduced.

According to the literature, CO reduced by 98%, HC by 70%, NO x by 39%, CO2 by 24%, SO 2 by 90%. At the same time, because the octane number of methane is above 120, the antiknock performance is improved and the engine noise is effectively reduced. LN G is a cryogenic liquid formed by deep freezing after dewatering and desulfurization (1011325 kPa, -161125 ℃ ). After purification and freezing, the harmful impurities have been cleared, the purity of CNG has been further improved, and thus the combustion products are more clean, more effective environmental benefits.

LNG Tank (Cryogenic Tank)

What is LNG?

LNG is an abbreviation for liquefied natural gas.

Natural gas is becoming more and more popular as clean energy, and many countries have ranked LNG as the preferred fuel, and the proportion of natural gas in energy supply has increased rapidly. Natural gas is a natural combustible gas that is naturally mined in the gas field, consisting mainly of methane. The LNG is condensed into liquid by cooling the gaseous natural gas at atmospheric pressure to -162 ° C. Natural gas liquefaction can greatly save storage space, and has a large calorific value, high performance.


In recent years, the global LNG production and trade has become increasingly active, LNG has become a scarce clean resources, is becoming the world’s new oil and gas industry hot spots. In order to ensure the diversification of energy supply and improve the energy consumption structure, some energy consuming countries pay more and more attention to the introduction of LNG, Japan, South Korea, the United States, Europe are large-scale construction of LNG receiving station. International big oil companies have also turned their new profit growth point to LNG business, LNG will become the next global competition for oil after the popular energy products.

China’s LNG industry is becoming more and more important. China is planning and implementing coastal LNG projects: Guangdong, Fujian, Zhejiang, Shanghai, Jiangsu, Shandong, Liaoning, Ningxia, Hebei Tangshan, etc. These projects will eventually form a coastal LNG Receiving station and conveyor pipe network.
