Problems solved by technology

However, when the external gas volume fluctuates greatly, the recondensation process cannot effectively condense BOG into LNG, resulting in part of the BOG being directly burned and discharged, resulting in a waste of energy

Abstract

The invention provides a receiving station liquefied natural gas (LNG) cold energy power generation and boiled off gas (BOG) recovery power generation coupling system and method. The receiving stationLNG cold energy power generation and BOG recovery power generation coupling system comprises an LNG cold energy power generation subsystem and a BOG power generation waste heat recovery subsystem, wherein the LNG cold energy power generation subsystem comprises a first heat exchanger 3, a second heat exchanger 11, a circulating working medium pump 12, a third heat exchanger 13 and an expansion power generator 14, and the BOG power generation waste heat recovery subsystem comprises an adjusting valve 5, a gas power generating set 7, an absorption heat exchanger unit 8, a hot / cold user 9, the third heat exchanger 13 and a fourth heat exchanger 15.

Description

technical field [0001] The invention relates to the field of comprehensive energy utilization of LNG receiving stations, in particular to a coupling system and method for LNG cold energy power generation and BOG recovery and power generation at the receiving station. Background technique [0002] With the development of global energy towards clean and low-carbonization, natural gas will occupy an important position in the future energy pattern. As a high-quality, efficient and clean low-carbon energy, natural gas will greatly improve environmental pollution compared with coal and oil. [0003] Natural gas is in a gaseous state at normal temperature and pressure, and the place of production is generally far away from the user. To facilitate the storage and transportation of natural gas, gaseous natural gas is usually liquefied into LNG (liquefied natural gas). Judging from the current LNG production process, the production of 1 ton of LNG consumes about 850kWh of energy. Th...
