Portable adsorption type natural gas recovery device and method

Abstract

The invention relates to a portable adsorption type natural gas recovery device and method. The device consists of a gas collecting module, a machine pump module, an adsorption module and a control module, wherein each of the modules comprises a natural gas bottle or an LNG bottle, a gasifier, a buffer tank, a vacuum pump, a natural gas compressor, an ANG bottle, a control cabinet, a pressure, temperature and oxygen detecting probe and various valves; main body equipment of the device is mounted on a gasifier prying block, a buffer tank prying block, a vacuum pump prying block and a compressor prying block; the prying blocks are in bolt connection, so that in-site assembled prying can be convenient to perform, and a vehicle-mounted natural gas recovery device can be made, so that the movement and the operation are convenient. The ANG bottles can be demounted, and replaced, and system operation is not influenced. The device is provided with a vacuum system for vacuumizing the system. According to the portable adsorption type natural gas recovery device and the method disclosed by the invention, natural gas exhausted from the natural gas bottles or the LNG bottles is collected to the gasifier and the buffer tank; a compressor is used for compressing the natural gas through medium pressure into the ANG bottles to be stored, so that recovery is realized. When being required by outside, gas in the bottles can realize desorption for use of energy resources.

Description

technical field [0001] The invention belongs to the technical field of natural gas recovery, and in particular relates to a portable adsorption type natural gas recovery device and a recovery method thereof. Background technique [0002] Some natural gas may be discharged from the natural gas associated gas produced in the oil production process, the residual gas of the natural gas pipeline and the filling of natural gas, and is often directly discharged into the atmosphere. The discharge of these natural gas not only deteriorates the environment, but also causes harm to human health. But also cause waste of resources and economic losses. In recent years, with the emphasis on environmental issues at home and abroad, the recycling of organic gases has become more and more important. The pollution control of organic gases has always been a key topic for environmental protection workers. [0003] Natural gas adsorption recovery is an advanced recovery method. Factors affectin...
