“…Other processes such as multi-stage flash distillation (MSF), multiple-effect distillation (MED), solar thermal distillation (SD), freezing, reverse osmosis (RO), ecletro-dyalysis (ED), ionexchange desalination (IE), and adsorption have been investigated, and industrially used, for seawater desalination [6,10,27,36,118,[200][201][202][203][204][205][206][207][208][209][210][211][212][213][214]. Table 9 presents a comparison between diverse technologies based on four criteria: Thermal Energy consumption, electrical energy consumption, production cost, and product water salinity.…”

“…Remember that seawater has an average of 35000 ppm TDS [210,216]. The high TDS value (here salinity) of product water via CPH-based desalination is strongly related to the salts trapped in the hydrate crystals [6,10,27,36,118,[200][201][202][203][204][205][206][207][208][209][210][211][212][213][214]. This requires efforts on post-treatment process to completely remove trapped salt and therefore achieve product water with quality that meets the WHO drinking-water criterions.…”

This article presents a systematic review on the past developments of Hydrate-Based Desalination process using Cyclopentane as hydrate guest. This is the first review that covers all required fundamental data, such as multiphase equilibria data, kinetics, morphology, or physical properties of cyclopentane hydrates, in order to develop an effective and sustainable desalination process. Furthermore, this state-of-the-art describes research and commercialization perspectives. When compared to traditional applications, cyclopentane hydrate-based desalination process could be a promising solution. Indeed, it operates under normal atmospheric pressure, lower operation energies are required, etc… However, there are some challenges yet to overcome. A decision aid in the form of a diagram is proposed for a new cyclopentane hydrates-based desalination process. Hopefully, concepts reviewed in this study will suggest new ideas to advance technical solutions in order to make commercial hydrate-based desalination processes a reality.

“…Management of produced water from Enhanced Oil Recovery (EOR) is one of the problems associated with the oil recovery since it produced large volumes of saline water, which should be managed as the by-product. The produced water contains several contaminants such as mineral ions, dispersed oil, grease, organics, heavy metals and other different contaminants [1] such as surfactant, polymer or the mixture of both surfactant and polymer (SP) resulting from the EOR injection. Good management of the produced water is important since it plays a major role in the environmental concern for reuse or discharge.…”

“…Therefore, the produced water treatment is economically reasonable and technically feasible. The objectives of the produced water treatment are to remove the oil, desalination, removal of soluble organics, naturally radioactive materials, dissolve gases, suspended particles and sand, disinfection and softening [1]. These polluting components must be minimized to allow the level and threshold of oil in the produced water is limited by legislation during the discharging [2].…”

The objective of this study was to investigate the effect of polymer and surfactant (MFOMAX) towards the efficiency of oil removal in a flotation column by using the Response Surface Methodology (RSM). Various concentrations of surfactant (250, 372 and 500 ppm) and polymer (450, 670, and 900 ppm) produced water were prepared. Dulang crude oil was used in the experiments. Flotation operating parameters such as gas flow rate (1-3 L/min) and duration of flotation (2-10 min) were also investigated. The efficiency of oil removal was calculated based on the difference between the initial concentration of oil and the final concentration of oil after the flotation process. From the ANOVA analysis, it was found that the gas flow rate, surfactant concentration, and polymer concentration contributed significantly to the efficiency of oil removal. Extra experiments were conducted to verify the developed equation at a randomly selected point using 450 ppm of polymer concentration, 250 ppm of surfactant concentration, 3 L/min gas flowrate and duration of 10 min. From these extra experiments, a low standard deviation of 1.96 was discovered. From this value, it indicates that the equation can be used to predict the efficiency of oil removal in the presence of surfactant and polymer (SP) by using a laboratory flotation column.
