Processes, Journal Year: 2022, Volume and Issue: 10(4), P. 738 - 738

Published: April 11, 2022

Oil–water emulsions are widely generated in industries, which may facilitate some processes (e.g., transportation of heavy oil, storage milk, synthesis chemicals or materials, etc.) lead to serious upgrading environmental issues pipeline plugging, corrosions equipment, water pollution, soil etc.). Herein, the sources, classification, formation, stabilization, and separation oil–water systematically summarized. The roles different interfacially active materials–especially fine particles–in stabilizing have been discussed. advanced development micro force measurement technologies for emulsion investigation has also presented. To provide insights future industrial application, by methods summarized, as well introduction equipment combined processes. gaps between demulsification applications touched upon. Finally, perspectives treatment technology discussed purpose achieving high-efficiency, energy-saving, multi-functional treatment. We hope this review could bring forward challenges opportunities research fields petroleum production, coal iron making, protection, etc.

Fouling in reverse osmosis membranes: monitoring, characterization, mitigation strategies and future directions

Heliyon, Journal Year: 2023, Volume and Issue: 9(4), P. e14908 - e14908

Published: March 28, 2023

Water scarcity has been a global challenge for many countries over the past decades, and as result, reverse osmosis (RO) emerged promising cost-effective tool water desalination wastewater remediation. Currently, RO accounts >65% of worldwide capacity; however, membrane fouling is major issue in processes. Fouling reduces membrane's lifespan permeability, while also increases operating pressure chemical cleaning frequency. Overall, quality quantity desalinated water, thus hinders sustainable application membranes by disturbing its efficacy economic aspects. arises from various physicochemical interactions between pollutants materials leading to foulants' accumulation onto surfaces and/or inside pores. The current review illustrates main types particulates, organic, inorganic biological foulants, along with factors affecting formation development. Moreover, currently used monitoring methods, characterization techniques potential mitigation strategies are reviewed. Further, still-faced challenges future research on addressed.

Gas Flotation of Petroleum Produced Water: A Review on Status, Fundamental Aspects, and Perspectives

Energy & Fuels, Journal Year: 2020, Volume and Issue: 34(12), P. 15579 - 15592

Published: Dec. 3, 2020

Produced water is a major byproduct in oil production and the largest waste stream generated petroleum industry. At Norwegian Continental Shelf, produced still mostly discharged to sea, but some installations re-inject into reservoir for pressure support or disposal. Gas flotation separation technology widely used both onshore offshore that generally reduces concentration <25 ppmv. It also promising subsea treatment. The aim of this review give an overview provide link between industrial use fundamental aspects gas flotation. analysis examines development design technologies: induced, dissolved, compact units. Several are discussed. dedicated fluid dynamics bubble–droplet collisions phenomena involved after their encounter, i.e., film drainage, forces process, spreading on surface bubbles. Moreover, detailed parameters can affect flotation, like bubble droplet sizes, droplet–bubble attachment mechanisms, interfacial properties, composition, pressure, temperature, provided.

Formulation in Surfactant Systems: From-Winsor-to-HLDN

Encyclopedia, Journal Year: 2022, Volume and Issue: 2(2), P. 778 - 839

Published: April 18, 2022

Formulation is an ancient concept, although the word has been used only recently. The first formulations made our civilization advance by inventing bronze, steel, and gunpowder; then, it was in medieval alchemy. When chemistry became a science with golden age of organic synthesis, second formulation period began. This possible to create new chemical species combinations “à la carte.” However, research developments were still carried out trial error. Finally, third history began after World War II, when properties system associated its ingredients way they assembled or combined. Therefore, systems’ phenomenology related generation some synergy obtain commercial product. Winsor’s studies 1950s enlightening for academy industries that studying empirically surfactant-oil-water (SOW) systems. One key characteristics how interfacial interaction adsorbed surfactant oil water phases could be equal varying physicochemical system. Then, Hansen’s solubility parameter 1960s helped reach further understanding affinity substances make them suitable phases. In 1970s, researchers such as Shinoda Kunieda, different groups working Enhanced Oil Recovery (EOR), among Schechter Wade’s group at University Texas, become using semiempirical correlations attain specific (e.g., low oil-water tension, stable O/W W/O emulsion, high-performance solubilization bicontinuous microemulsion so-called optimum formulation). Nowadays, over 40 years hydrophilic-lipophilic deviation equation (HLD) have feasible formulators improve products many applications surfactants target HLD original normalized form, i.e., HLDN. Thus, can said there current progress being towards interdisciplinary applied numerical guidelines. present work, state-of-the-art multiphase systems containing two immiscible like water, therefore heterogeneous micro-heterogeneous interfaces, discussed. Surfactants, from simple complex polymeric, are generally solve wide variety problems areas. Some significant cases presented here examples dealing petroleum, foods, pharmaceutics, cosmetics, detergency, other occurring dispersions, emulsions, foams we find everyday lives.
