Research on Freezing and Blocking Problems in Liquefied Natural Gas Factories and Design of Process Plans

Abstract

Liquefied natural gas is a clean and efficient energy source. As a rising star in the global energy industry, LNG import and export is expanding, which mainly depends on two aspects. For energy consuming co-untries, importing LNG can achieve energy diversification, reduce energy costs, and ensure energy security. For LNG exporting countries, it is beneficial to the full development of natural gas energy, increase the foreign exchange income, and promote economic growth. It analysis the merits and drawbacks of every proposals from process simulation, process description, applicability, temperature parameters, liquefaction energy consumption, major equipment, investment etc. With increasing environmental protection pressure and environmental protection requirements become higher than before. LNG is conducive to improving the utilization efficiency of natural gas, which is in line with the country's strategy of replacing coal. The LNG market has broad prospects, high added value and good benefits. Although the price of LNG is higher than that of pipeline gas, it still has a advantage compared with oil.
