Industrial developments in the oil and gas, petrochemical, pharmaceutical and food sector
have contributed to the large production of oily wastewater worldwide. Oily wastewater …

Highlights•The membrane surface wettability exhibits dual pH-and ammonia-vapor-
responsive.•The membrane may facilitate oil-water separation via remote control.•The …

In this paper, a mechanical coalescer is tested to coalesce the oil droplets in the oil-in-water
(O/W) emulsions. The coalescence of the O/W emulsions through fibrous and granular beds …

This paper addresses the use of electrodialysis (ED) to remove salts from produced water
(PW) to meet drinking water, irrigation water, and/or livestock watering standards …

Produced water from polymer flooding was much more difficult to be treated than that from
water flooding in many oilfields. The simulated experimental results showed that the small …

Crude oil mixture extracted from the underground; contains water, gas and solid particles,
and this mixture firstly separated by a process described in the literature as 1st Process, from …

Emulsion separation has global environmental implications owing to the increasing
generation of oily industrial wastewater and oil spill incidents. For most existing emulsion …

Numerous oil wells, especially in their middle-late periods, are becoming less economic due
to the high lifting costs and reduced recoveries. The downhole oil–water separation (DOWS) …

In order to solve the global problem of waste oil pollution, develop highly effective oil-water
mixtures separation materials become necessary, especially in those industries where exist …

The most widely utilized process of produced water treatment is considered to be use of
coalescing or corrugated plate systems in the oil industry because these systems have …
