...Ming Xue; Xingchun Li; Xiangyu Cui; Xin Cheng; Shuangxing Liu; Wenjia Xu; Yilin Wang Summary As one of the largest emitters in the world, the oil and gas industry needs to apply more effort to greenhouse gas (GHG) reduction. Methane, as a potent GHG, could largely determine whether natural gas...

... tendency and therefore the need for improved softening. In Field D, the service cycle, the backwash cycle, and the brining cycle were optimized leading to a gain in throughput and reduction in salt consumption. Service cycle improvement gained 30 to 130% in throughput between two regenerations, backwash...

The bigger bubbles (100 µm size) were affected only at a salinity of 40 000 mg/L, whereas the smaller bubbles (20 to 30 µm) remained stable and did not change with the further increase of salinity. Coagulant affected the water chemistry with a high effect on pH and oxidation‐reduction potential (ORP...
