Abstract
A pretreatment system for natural gas liquefaction employing heat integration for more efficient and effective natural gas temperature control. The pretreatment system expands the natural gas prior to acid gas removal. After acid gas removal, the natural gas is cooled by indirect heat exchange with the expanded natural gas located upstream of the acid gas removal system.
