Abstract

Liquified natural gas (LNG) is the cleanest of fossil fuels. Before liquefying natural gas, it is essential to convert raw gas into LNG quality gas by separating unwanted levels of constituent substances such as hydrogen sulfide (H₂S), CO₂, water, and natural gas liquids. Herein, we explain in simple terms the processes of absorption and adsorption used to lower the concentration of H₂S and CO₂ with special attention on amine solvents. Subsequent sections present the dehydration methods, the separation of natural gas liquids and the process of fractionation. The chapter also presents the most popular natural gas cryogenic liquefaction cycles.
