Problems solved by technology

The existing onshore natural gas liquefaction devices generally cannot be directly used in offshore production environments. Although dynamic equipment such as compressors and buffer tanks have been used in FPSO, the core equipment of natural gas liquefaction devices, LNG main heat exchangers, throttle valves, etc. The adaptability to the offshore environment has not yet been verified, especially the application of the coiled tube heat exchanger in FLNG is rarely reported at home and abroad. Therefore, it is necessary to study a test platform for testing the floating natural gas liquefaction system

Abstract

The invention discloses a test platform for a floating natural gas liquefaction system, comprising: a cryogenic compression module, the cryogenic compression module is sequentially connected with a pre-cooling heat exchange module and a cryogenic heat exchange module to form a cycle; the pre-cooling compression module, The pre-cooling compression module is connected with the pre-cooling heat exchange module to form a cycle; the LNG vaporization compression module is sequentially connected to the pre-cooling heat exchange module and the cryogenic heat exchange module to form a cycle; The pre-cooling heat exchange module and the cryogenic heat exchange module are arranged on the shaking unit. It can be used to test the operating performance of core equipment such as plate-fin heat exchangers, coiled tube heat exchangers, throttle valves, and gas-liquid separators in the natural gas liquefaction system in marine environments, as well as the adaptability of the natural gas liquefaction system.

Description

technical field [0001] The invention relates to the technical field of test platforms, in particular to a test platform for a floating natural gas liquefaction system. Background technique [0002] There are abundant natural gas resources under the ocean. According to estimates by international oil and gas authorities, marine natural gas reserves account for about 50%-55% of the world's total natural gas reserves. In 2004, the world's marine natural gas production exceeded 1 trillion cubic meters, accounting for It is estimated that by 2015, the proportion of marine natural gas production in global natural gas production will increase to 34%, reaching 1.3 trillion cubic meters. With the increasing shortage of energy and the increasing demand, the development of marine natural gas resources is gradually becoming an important energy development strategy of various countries. The Ministry of Land and Resources of the People's Republic of China announced at the end of February ...
