Zero-emission novel LNG container

Abstract

The invention discloses a zero-emission novel LNG container. The zero-emission novel LNG container comprises a container frame (1), an LNG storage tank (2), a refrigeration device (3) and a heat dissipation system (4); the container frame (1) is provided with the LNG storage tank (2), and the LNG storage tank (2) is provided with the refrigeration device (3); the refrigeration device (3) comprisesa hot end (31) and a cold end (32); the heat dissipation system (4) is connected to the hot end (31) of the refrigeration device (3), the cold end (32) of the refrigeration device (3) is arranged inside the LNG storage tank (2), the hot end (31) of the refrigeration device (3) is arranged outside the LNG storage tank (2); and the refrigeration device (3) and the LNG storage tank (2) are connectedin an integral mode by welding; and an aluminum heat sink (5) is installed at the cold end (32) of the refrigeration device (3). According to the zero-emission novel LNG container, the non-pressure-relief transportation time of LNG can be effectively prolonged, the BOG emission is reduced, and the resource waste and the environmental pollution are avoided.

Description

technical field [0001] The invention relates to the technical field of oil and gas treatment, in particular to a new type of zero-emission LNG container. Background technique [0002] LNG containers generally use increased design pressure to deal with BOG generated during LNG transportation. The LNG container can store LNG for about 90-120 days without depressurization. If the container reaches the design pressure before reaching the end user, especially during long-distance transportation, the emptying safety valve on the upper part of the container will activate to depressurize the storage tank. This not only causes a waste of natural gas, but also increases environmental pollution and danger during transportation. [0003] At present, the commonly used methods to prolong the transportation time of LNG containers include increasing the wall thickness of LNG storage tanks or adding protective coatings, etc., but these methods are costly and have poor economic benefits, an...
