What is LNG gas?

LNG (Liquefied Natural Gas) is natural gas that is liquefied by deep cooling to minus 160 oC after removing impurities. LNG is composed mainly of methane.

LNG is a colorless, odorless, non-toxic and non-corrosive gas with a flame temperature of about 2340ºC and is lighter than air. Composed mainly of methane (about 95%) and small amounts of other gases.

Natural gas is liquefied at -120ºC to -170ºC (depending on the ratio of mixture components in the gas), making it easy to store and transport. Despite its advantages over petroleum such as higher energy density, reduced refueling times and reduced environmental pollution, LNG has not been widely adopted in developing countries. This is mainly due to the very high cost of investing in storage and transportation facilities, infrastructure, equipment, and processing machinery. Therefore, in the past, LNG was only used in countries with strongly developed industries such as the US, UK, Japan and European countries.

LNG (Liquefied Natural Gas) is essentially liquefied natural gas (NG) , the main component is CH 4 gas.

LNG can be viewed as an ‘expanded’ gas from compressed natural gas (CNG). Compressed natural gas must be compressed at a very high pressure from 230 bar to be stored in tanks transported to the point of consumption, this is a great obstacle in terms of the radius of the path, it is also the reason making the cost not cheaper than traditional fuels.

LNG overcomes the existing disadvantages that CNG has to face because it is safer, can hold more, can be carried further, which means more economic efficiency.

What is LNG gas?
LNG is stored in large capacity tanks, which are transported by large cargo ships.

The main component LNG is CH 4 extracted from natural gas fields in the open sea, leading to the mainland and through a processing and cooling system at -163 degrees Celsius, at which point natural gas becomes a state. liquid.

LNG is stored in large capacity tanks, they are transported by large cargo ships from one country to another via sea. On land, LNG is transported by means of transportation to the point of consumption, LNG will be processed through a special evaporator to turn the liquid into pure NG natural gas…

LNG is an alternative fuel source, a current and future supplementary fuel source for each country, LNG is towards an industry that emits clean gas after burning into the environment, LNG is applied in vehicles. Transport and especially LNG is the highlight for thermal power plants of each medium and large-scale production…

LNG is very popularly traded in the international market and has become an important energy source of many countries around the world such as Japan, Korea, Taiwan, China, European countries and North America… The world’s largest LNG exporter is in the Middle East, Southeast Asia (Malaysia, Indonesia), Australia, and Russia. Northeast Asia is a traditional LNG consumption market with Japan being the world’s largest LNG importer with an annual output of about 80 million tons.

LPG is a colorless, odorless gas (with an added odor to make it easier to detect when leaking), a flame temperature from 1890ºC to 1935ºC, lighter than water but heavier than air.

Petrol gas is a by-product obtained during oil processing. The gas is liquefied to form LPG. The chemical composition is mainly propane, butane and a small amount of propylene, butylene and other gases. In fact, the composition of substances in LPG is not uniform. Depending on the standards of different countries and regions, the ratio between propane and butane varies.

CNG is a colorless, odorless gas with a flame temperature of about 1950ºC and is lighter than air. CNG is mainly composed of hydrocarbons, of which methane can make up 95%, ethane makes up 5% to 10%, and small amounts of propane, butane and other gases.

Usually, sulfur flavor is added to make it easier to detect when a leak occurs. Because it is lighter than air, in the event of a leak, natural gas (both CNG and LNG) does not cause as serious damage as gasoline or LPG.
