Flaring is a major concern in the oil and gas industry as it wastes valuable raw materials/energy and emits a substantial amount of air pollutants. The produced water treatment during oil and gas production is very troublesome due to its large processing volume, high salinity, and expensive disposal cost. Thus, the on‐site integration of the flaring gas recovery (FGR) and desalination processes for handling the produced water could not only monetize flare emission sources but could also generate freshwater for versatile usages. Here, a novel process was developed integrating the ejector‐based FGR (EFGR) process with the thermal vapor compression (TVC)‐based desalination process. The newly developed EFGR‐TVC process is shown to be technically viable and cost‐effective under normal operating conditions.

页岩气生产中集成的基于喷射器的火炬气回收和现场除盐水

燃烧是石油和天然气工业中的一个主要问题，因为它浪费了宝贵的原材料/能源，并散发出大量的空气污染物。由于其处理量大，盐度高且处置成本昂贵，因此在油气生产过程中产生的水处理非常麻烦。因此，用于处理采出水的火炬气回收（FGR）和脱盐工艺的现场集成不仅可以将火炬排放源货币化，而且还可以产生淡水以用于多种用途。在这里，开发了一种新颖的工艺，将基于喷射器的FGR（EFGR）工艺与基于热蒸气压缩（TVC）的脱盐工艺相结合。事实证明，新开发的EFGR-TVC工艺在正常运行条件下在技术上可行且具有成本效益。
