A systematic design strategy for spiral-wound gas separation systems is studied using a recently proposed algebraic permeator model (Qi and Henson, Approximate modeling of spiral-wound gas permeators, J. Membrane Sci. 121 (1996) 11–24). Nonlinear programming (NLP) is used to determine operating conditions which satisfy the separation requirements while minimizing the annual process cost. The de...

Abstract Oil–water mixing has brought many problems to a society, and it is of great significance develop simple, convenient, efficient, durable separation material solve the problem oil–water mixing. In this paper, modified cottons were successfully prepared using polydopamine as in situ mineralization site TiO 2 nanoparticles combined with synergistic crosslinking KH550. A large number hydrop...

Bergamot peel oil is highly attractive for food and pharmaceutical industries due to its content of valuable essential oil, which is enriched with high-added valuable compounds, such as limonene, linalool and linalyl acetate. Nevertheless, there are some limitations for the separation of such compounds. In this framework, pervaporation (PV) technology was proposed as a ...

Six Korea high oil (KHO) corn varieties varying in germ and endosperm size and oil content (4-21%, wet basis) were subjected to three sequential combinations of milling (M), germ separation (S), fermentation (F), and in situ transesterification (T) to produce bioethanol and biodiesel. Production parameters including saccharification, bioethanol yield, biodiesel yield and composition, and conver...

There is a large amount of oil-contaminated wastewater caused by oil/gas production and marine oil spills. It still major challenge for the development oil/water separating membranes that have excellent separation efficiency, can withstand saline environments, long-term durability. We present new membrane made ultralong titanate nanofibers (TNF) (with diameter 200 nm length 60 µm) carbon (CNF) ...

We report a parallelized capillary microfluidic device for enhanced production rate of monodisperse polymersomes. This device consists of four independent capillary microfluidic devices, operated in parallel; each device produces monodisperse water-in-oil-in-water (W/O/W) doubleemulsion drops through a single-step emulsification. During generation of the double-emulsion drops, the innermost wat...

This investigation aims to determine whether it is feasible use the limestone rocks found in Al-Samawa stone quarry southern Iraq as stationary phase column chromatography separation. Together with chromatographic application, physical and chemical characteristics of are examined. SiO2, SO4, PO4, NO3, Cl negative ions, while Ca, Mg, Na, K, Li positive ions. The samples characterized via analysi...

Separation of water-in-oil emulsion is a significant part the cost oil production due to use expensive demulsifiers and additional heating by burning associated petroleum gas. The article discusses an acoustic method that enables increasing rate separation emulsion. In field conditions, tests were carried out in which efficiency was determined depending on temperature product, concentration dem...

Growth of surface instabilities leading to periodic oil patterns in electrowetting display pixels has been experimentally observed. In the electrowetting display pixels, an electrical potential ranging between 0 V and 80 V is applied among a water electrode, dielectric layers consisting of an oil film, fluoropolymer, Parylene C and a lower electrode. As predicted by spinodal dewetting theory, a...
