Abstract

In this paper, the analysis of liquefied natural gas process plant technology, into the device before the natural gas compression, and then through the MEA aqueous solution to remove CO2. Finally, the compressed water removed; clean natural gas before entering the liquefaction unit. In the liquefaction unit, the high-pressure natural gas is cooled and liquefied deep. The required cooling capacity is obtained by circulating the gas turbine to drive the closed mixed refrigerant nitrogen, methane, ethylene, propane and other components, and liquefied natural gas (LNG), which is finally stored in an atmospheric tank through a liquefied natural gas container or liquefied natural gas tanker for distribution. The recycle of the recycle refrigerant is carried out by means of environmental conditions. The heating medium required during the installation process is the hot oil heated by the exhaust gas of the gas turbine. The liquefied gas in the liquefied natural gas tank is compressed to regenerate the desiccant and then sent to the gas turbine as the fuel gas.
