The Natural Gas Liquefaction Technology for Small-Scale LNG

Abstract

LNG production is an energy-consuming process, which requires significant amount of capital and operating costs. This is one of the reasons why these plants slowly spread. On the contrary small-scale LNG provides flexibility of the project and accelerates its implementation but it uses simple and ineffective liquefaction technologies. The aim of the study is to create a power-efficient small-scale LNG technology. The main tasks are review, comparative analysis and identification of energy-efficient cycles, development of technology based on the analysis of the latest technological solutions and thermodynamic calculation of the refrigeration unit. As a result, a technology based on the nitrogen cycle was developed.
