Comprehensive Solution to Improve the Efficiency of the LNG Energy Complex Through the Use Cold Energy of Cryoproducts

Abstract

In this paper, the object of the study is a power complex, which includes a set of several circuits, to provide electricity to settlements or human facilities. The scheme of this complex consists of the main circuit (gas piston power unit [1]), auxiliary power unit (air separation unit (ASU) [2]), multistage expansion and steam power units using argon and oxygen as working substances. Liquid methane is used as the main fuel. The energy performance of auxiliary steam-power plants operating with cryogenic working bodies has been calculated, and an index of influence of heat exchange apparatus parameters on working body temperatures has also been found.
