Problems solved by technology

However, the existing vented natural gas collection systems and methods do not consider the impact of economy and timeliness on actual projects, and only rely on the pressure of the vented natural gas to recover, the collection efficiency is low, and the natural gas is not filtered and classified and impurities are discharged. Preserved in the form of gas, the economic benefits are not high, the safety is low, and there are huge equipment, inflexible relocation, or a serious imbalance between investment and production; in order to efficiently promote the recovery of vented natural gas, it is necessary to invent a New natural gas vent collection system and method

Abstract

The invention discloses a vehicle-mounted collecting system for vented natural gas. The vehicle-mounted collecting system comprises a gas extraction module, a pressure and flow stabilization module, a natural gas purification module, a natural gas liquefaction module, a vehicle-mounted power module, a liquid storage and transportation module and an emergency function module. The gas extraction module is used for sucking vented natural gas, the pressure and flow stabilization module is used for adjusting the pressure and flow of natural gas, the natural gas purification module is used for purifying and sucking the natural gas; the natural gas liquefaction module is used for liquefying and recovering the natural gas; the vehicle-mounted power module is used for system bearing and power supply; the liquid storage and transportation module is used for storing and transporting the liquefied natural gas; and the emergency function module is used for guaranteeing operation safety. According to the vehicle-mounted collecting system, the vented natural gas can be rapidly collected, purified and liquefied, converted into liquefied natural gas, stored in the storage tank and transported to a safety station to be directly used, vehicle-mounted system integration of recovery, purification, liquefaction, storage and transportation of the vented natural gas is achieved, and the purposes of flexible and convenient operation, improved collection efficiency, operation economy improvement and environmental protection are realized.

Description

Technical field [0001] The present invention is designed to be used in the field of petrochemical environmental protection technology, and specific relates to a radial natural gas vehicle collection system and method. Background technique [0002] Natural gas refers to a type of flammable gas present in nature, a fossil fuel, which will drive with coal and oil in a primary energy consumption. During mining, delivery, and processing, due to the need for production and operation, there is a phenomenon of emptying natural gas, and there are often two forms of cold and hot emission. For example, during the production of oil and gas fields at home and abroad, there is a phenomenon that is emptied to natural gas, especially when the new well drill is completed, and there will be gas discharge, often use hot emission (combustion and empty natural gas); When the gas pipeline (long-distance pipeline or urban gas pipeline) is changed or accidentally repaired, it is necessary to vent the na...
