摘要/Abstract

摘要： 天然气田、加气站经常有天然气排放到大气中,不仅带来了严重的安全隐患和潜在的环境问题,还会带来资源浪费和经济损失。目前,天然气回收技术尚未普及,已有的回收技术普遍存在压力过高、能耗过高、对设备条件要求过高等不足,在使用中还不具备便携、可拆等问题。因此,开发出一种移动组合式吸附天然气回收装置。该装置由气化器撬块、缓冲瓶撬块、真空泵撬块、压缩机撬块和ANG 气瓶撬块5个撬块构成,并对每个撬块进行设计及选型、装置性能评估及现场应用案例介绍。该装置可将油气田或天然气瓶或LNG瓶排放出来的天然气收集到气化器、缓冲罐内,再利用压缩机将该天然气压缩至ANG瓶内储存,以实现在中压(~4 MPa)下高效吸附回收天然气,充气比达80以上。现场应用表明连接本装置后其碳排放量降低97%以上。该装置具有高效、安全、可拆、便携、移动、监控、变频、触摸屏控制等优点。

Abstract: There are many chances for natural gas to emit from gas fields or natural gas stations into the air, and the discharged gas not only leads to serious safety hazard and potential environmental issue, but also brings about unregenerate energy resource waste and economic losses. Natural gas recovery technology has not yet been popular for industrial applications, because there are generally some disadvantages for the existing recovery technologies, such as high pressure, high energy consumption, high requirements of equipment condition, nonportable and nondetachable in use. Therefore, a mobile combined adsorption natural gas (ANG) recovery equipment was developed, which was composed of five skids for portability, including gasifier skid, buffer bottle skid, vacuum pump skid, compressor skid and ANG cylinder skid. Then, the design and selection of devices for each skid were conducted, the equipment performance was evaluated, and the field application case was introduced. The equipment can collect the natural gas discharged from the gas fields or the natural gas cylinders or the LNG cylinders into the gasifier and the buffer tank, and then compress and store the natural gas into the ANG cylinder by the compressor, to realize to adsorb and recover the natural gas high efficiently in a medium pressure (~4 MPa) and with a volumetric ratio of the filled gas to ANG cylinder of more than 80. Meanwhile, the field application of the equipment showed that the carbon emissions in the field would be reduced by more than 97%. The equipment has advantages of high efficiency, safety, detachable, portable and mobile, autocontrol and touch screen control.
