The refrigeration and liquefaction section is the key element of the LNG plant. There are a lot of licensed processes available with varying degrees of application and experience. The basic principles for cooling and liquefying the gas using refrigerants involve matching as closely as possible the cooling/heating curves of the process gas and the refrigerant. This results in a more efficient thermodynamic process requiring less power per unit of LNG produced. This applies to all liquefaction pro
