原油在集输储运过程中会由于蒸发而损失一部分轻质组分,造成天然气资源的浪费的同时,还对大气环境造成污染。如果对这些组份加以回收,不仅减增加了油田天然气产量,又减少了能源浪费;防止了油罐顶挥发出天然气对大气的污染,保护了环境;同时减少了油罐区火灾危险因素,增加了油气集输的安全性。“,”due to evaporation and loss of crude oil wil be a part of light fractions ingathering processing,storage process,resulting in the waste of natural gas resourcesat the same time,also causes pol ution to the atmospheric environment.If thesecomponents to be recycled,not only reduce the increase of oil natural gas production,but also reduces the waste of energy;preventing tank volatile gas on the atmosphericpol ution,protect the environment;at the same time reduce tank area fire hazard factors,increases the safety of oil and gas transportation.
