Movable type method and device for supplying liquid phase natural gas and gas phase natural gas

Abstract

The invention discloses a movable device for supplying liquid phase natural gas/gas phase natural gas. The device is characterized by comprising a shell with a bottom surface and a movable machine thereof. A miniature LNG low-temperature storage tank, an immersed pump, a submerged burning type gasifier, an LNG liquid filler and an air-bathing gasifier are arranged in the shell, wherein the LNG low-temperature storage tank is used for providing liquid phase LNG; the immersed pump is used for pumping the liquid phase LNG; the submerged burning type gasifier is used for converting the liquid phase LNG fed from the immersed pump into gas phase LNG so as to supply the gas phase LNG to a natural gas pipe network; the LNG liquid filler is used for filling liquid phase LNG fed from the immersed pump into a LNG flask group or filling the liquid phase LNG into LNG automobile; and the air-bathing gasifier is used for adjusting the saturation state of media in the storage tank and providing the gas phase LNG to the natural gas pipe network, and is used as an unload supercharging gasifier of LNG tanker. The method and the device have a greatly optimized process flow, a short flow, highly integrated process and equipment, multiple realized functions, high utilization rate of devices and equipment, multiple functions on one object basically, high cost performance and high safe reliability.

Description

technical field [0001] The invention relates to the technical field of liquid-phase natural gas and gas-phase natural gas supply. Background technique [0002] Natural gas (NG) is extracted from the ground and obtained after necessary purification treatment. Liquid natural gas (LNG) is a kind of clean energy that is made from NG that is further purified, removed impurities and cryogenically cooled to about -162°C to make it into a liquid state. Both NG and LNG can be used as alternative energy sources for fuel vehicles as vehicle engine fuels. Obviously, NG and gasified LNG can be used by various users through pipelines, which has significant economic and environmental advantages. [0003] In recent years, with the rapid development of the liquefied natural gas industry, the world's liquefied natural gas vehicle industry has made great progress. Currently, there are more than 10,000 LNG vehicles in operation around the world. The countries that use the most are the United...
