Abstract

Abstract

Introduction The technical analysis and investigation on the application of process equipment in the gasification area of the LNG (Liquefied Natural Gas) emergency reserve center, is carried out to solve the problems of frosting and icing in the operation of a single grouping of ambient air vaporizers, in the gasification area of Xi'an Yinzhen LNG emergency reserve center.
Method The LNG gasification technology in use mainly included ambient air vaporizing and water-bath vaporizing in Chinese Mainland. When the ambient air vaporizer was operated with high load and in low temperature seasons, it was easy to fog around the equipment, and the equipment surface would always be covered with frost and ice but the water-bath vaporizer did not have this phenomenon. After the investigation and comparison of the operation of gasification equipment in various station gasification process areas, such as LNG reserve centers and coastal terminals in recent years, the independent LNG water bath vaporizer could realize the gasification production without frost, ice and fog on the surface of the equipment in engineering; The combined operation system of the water-bath vaporizer and the ambient air vaporizer could combine and optimize the LNG gasification, which could not only obtain the heat energy contained in the air for LNG gasification production, but also eliminate the impact of low-temperature fogging, ice and frost on LNG gasification production.
Result The gasification process in Chinese Mainland of LNG with large reserve can smoothly complete the production without being affected by low temperatures.
Conclusion To build a green energy system, based on the formation of a new energy network, high-efficiency energy transmission, distribution, storage and conversion technologies as well as the integration and complementary development of the natural gas, wind, solar, water, hydrogen, and other renewable clean energies for gas power generation, have important supporting roles in perfecting energy storage engineering and technology, thus the optimization of large-scale LNG gasification technology is an important engineering practice.
