Abbreviations:
LNG - Liquefied Natural Gas
RPT - Rapid Phase Transition
LDC - Local Distributing company
IPP - Independent Power plants
LNG:
Natural gas is extracted from source and is condensed under the temperature -162 degrees Celsius into liquid, which takes space about 1/600 that in gaseous state. The liquefaction is to provide safe and convenient storage and transportation through seas. It is generally preferred when the distance overseas is larger and transportation of gaseous Natural gas is not possible through pipelines and becomes expensive. Maximum pressure for transportation is set at 25 KPa
The natural gas is predominantly methane (CH4) and having some mixture of Ethane compounds.The liquefaction, heavy gases like Helium, dust, heavy hydrocarbons, acid gases and water.
Production:
The natural gas is fed into LNG plant shall be treated to remove water, Hydrogen Sulphide, Carbon Dioxide, and other components that will freeze (Eg.Benzene) under the low temperatures needed for storage or be destructive to the liquefaction facility. LNG typically contains more than 90 percent of methane. It also contains amounts of ethane, propane, butane, some heavier alkanes and Nitrogen.
The purification process can be designed to give almost 100 percent methane. One of the risks of LNG is a rapid phase transition explosion (RPT), which occurs when cold LNG comes to contact with water.
Infrastructure:
The Most important infrastructure needed for LNG production and transportation is LNG plant consisting of one or more LNG trains, each of which is an independent unit for gas liquefaction. The largest LNG train in operations is in Qatar, with total production capacity 7.8 million metric ton per anum.
The Qatar operation overtook the train 4 of Atlantic LNG in Trinidad and Tobago with a production capacity of 5.2 mmtpa, followed by SEGAs LNG plant in Egypt with a capacity of 5 mmtpa
LNG is loaded onto ships and delivered to a regasification terminal, where the LNG is allowed to expand and reconvert into gas. Regasification terminals are usually connected to a storage and pipeline distribution network to distribute natural gas to local distribution companies (LDCs) or IPPs
