Description
Technical field: [0001] The invention relates to the technical field of detection equipment, in particular to a laser scanning tomography concentration field reconstruction system and method for methane leakage in a natural gas station. Background technique: [0002] Industrial production and people's normal life do not rely on natural gas. As a clean energy source, natural gas has been favored by people. Natural gas is flammable and often comes out when crude oil is extracted in oil fields. Its main component is methane, and it also contains a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc. [0003] In the natural gas gathering and transportation system, the natural gas station plays an important role and directly affects the safe operation of the natural gas gathering and transportation system. Due to the large number of natural gas equipment in the station, the control process is very complicated, and there are many sealin...
