Gasifying system for liquefied natural gas receiving terminal

Abstract

The invention discloses a gasifying system for a liquefied natural gas receiving terminal. The gasifying system comprises a floatation type gasifying vessel module and a land module, wherein the floatation type gasifying vessel module comprises a floatation type gasifying vessel; at least one storage cabin is arranged on the floatation type gasifying vessel; the storage cabin is internally provided with a backward flow pump and an in-tank pump; the backward flow pump is communicated with a loading arm; the loading arm is connected with a discharging arm through a discharging main pipe; the in-tank pump is sequentially communicated with a high-pressure pump suction tank a, an LNG (Liquefied Natural Gas) high-pressure pump a, an LNG main gasifying device a and a pressure regulation metering crowbar a; an output end of the pressure regulation metering crowbar a is connected with a high-pressure gas transmission arm; an output end of the high-pressure gas transmission arm can be connected with a natural gas pipe network through pipelines; the storage cabin is communicated with a gas return arm a; and the gas return arm a is communicated with a gas return arm b through a BOG (Boil Off Gas) main pipe. The gasifying system disclosed by the invention overcomes the limitations of long construction period of the general land large LNG receiving terminal, large influences of neighboring environments and soil resource limitation, and poor flexibility and the like, and is good for rapid construction and production of a project.

Description

technical field [0001] The invention relates to a gasification system of a liquefied natural gas receiving terminal. Background technique [0002] At present, while China's economy continues to develop rapidly, the energy that guarantees economic development is extremely scarce. Natural gas accounts for only 4.4% of China's primary energy consumption, far below the world average. As the country's demand for energy continues to grow, the introduction of LNG will play an important role in effectively solving energy supply security, optimizing energy structure, improving the ecological environment, and achieving sustainable economic and social development. Therefore, in recent years, China's liquefied natural gas (LNG) industry has developed rapidly, and LNG receiving terminals have attracted widespread attention. At present, LNG resources are mainly obtained from abroad, and they need to be transported to the country by large ocean-going ships. The LNG receiving terminals wi...
