“…The use of polymeric chemical species as chemical demulsifiers is gaining increasing attention. Demulsifiers formulated from polymers, such as alkene oxides diester, ethylcellulose (EC), Tween non-ionic polymer, and polyester, have been widely studied for the demulsification of crude oil emulsions [81,103,105]. Variation in the concentration of these polymeric demulsifiers has often resulted in different degrees of demulsification efficiency, with the highest demulsification efficiency of 97.5% recorded within 45 min of the demulsification process using a polyester-based demulsifier.…”

The processing of crude oil often requires the extraction of a large amount of water. Frequently, crude oil is mixed with water to form water-in-crude oil emulsions as the result of factors such as high shear at the production wellhead and surface-active substances that are naturally present in crude oil. These emulsions are undesirable and require demulsification to remove the dispersed water and associated inorganic salts in order to meet production and transportation specifications. Additionally, the demulsification of these crude oil emulsions mitigates corrosion and catalyst poisoning and invariably maximizes the overall profitability of crude oil production. Recently, there has been growing research interest in developing workable solutions to the difficulties associated with transporting and refining crude oil emulsions and the restrictions on produced water discharge. Therefore, this paper reviews the recent research efforts on state-of-the-art demulsification techniques. First, an overview of crude oil emulsion types, formation, and stability is presented. Then, the parameters and mechanisms of emulsification formation and different demulsification techniques are extensively examined. It is worth noting that the efficiency of each of these techniques is dependent on the operating parameters and their interplay. Moreover, a more effective demulsification process could be attained by leveraging synergistic effects by combining one or more of these techniques. Finally, this literature review then culminates with propositions for future research. Therefore, the findings of this study can help for a better understanding of the formation and mechanisms of the various demulsification methods of crude oil to work on the development of green demulsifiers by different sources.

“…Hydrogen sulfide is one of the toxic acid gases [5], which not only causes worse corrosion in NG transport pipes and NG storage tanks but also causes health issues, such as paralysis and coma, and death [6,7]. To eliminate corrosion and health damages, the sales NG specifications require that the hydrogen sulfide concentration of NG should be limited to below 6 ppm in China; thus, it is essential that a hydrogen sulfide removal process is adopted [8][9][10][11]. Afterward, the hydrogen sulfide is converted to sulfur using a sulfur recovery unit in natural gas purification plants [12,13].…”

The oxidation-absorption technology of tail gas is perfect for natural gas purification plants to ensure the up-to-standard discharge of sulfur dioxide emissions, but it can produce a large amount of wastewater. In this paper, a facile and full-scale reuse treatment strategy based on the sequential combination of disc tube reverse osmosis and low-temperature and low-pressure evaporation desalination was proposed and studied. The produced light yellow wastewater was acid sulfate-rich organic wastewater, in which sulfate ions (SO42−) existed up to 6479 mg/L, and the chemical oxygen demand (COD), 5-day biochemical oxygen demand (BOD5), total organic carbon (TOC), ammonia nitrogen (ammonia-N), total nitrogen (TN) and suspended solid (SS) were 207, 71.9, 67.6, 1.28, 70.5 and 20.9 mg/L, respectively. After the reuse treatment, there was COD (6 mg/L), BOD5 (1.4 mg/L), TOC (0.9 mg/L), TN (2.07 mg/L), SS (6 mg/L) and SO42− (90 mg/L) in permeated water, and condensate water with COD (11 mg/L), BOD5 (2.3 mg/L), TOC (4.3 mg/L), SS (2 mg/L) and SO42− (1.2 mg/L) was obtained. Thereby, pollution indexes were reduced after the reuse treatment so as to meet the water quality standard (GB/T18920-2022) in China, and the total water recovery rate reached 98.2 vol%. Ultimately, the priority pollutant migration mechanism during the reuse treatment process was determined.

Hydrogen sulfide H 2 S scavengers are chemicals that favorably react with hydrogen sulfide gas to eliminate it and produce environmental friendly products. These products depend on the type and composition of the scavenger and the conditions at which the reaction takes place. The scavenger should be widely available and economical for industry acceptance by having a low unit cost. The optimum values of H 2 S scavenger injection dose rate of scavenging hydrogen sulfide from the multiphase fluid produced at different wells conditions in one of the Petroleum Companies in Egypt were studied. The optimum values of H 2 S scavenger injection dose rate depend on pipe diameter, pipe length, gas molar mass velocity, inlet H 2 S concentration and pressure. The optimization results are obtained for different values of these parameters using the software program Lingo. In general, the optimum values of H 2 S scavenger injection dose rate of the scavenging of hydrogen sulfide are increased by increasing of the pipe diameter and increasing the inlet H 2 S concentration, and decreased by increasing the pipe length, gas molar mass velocity and pressure.
