Sugarcane green ceramic hollow fibre membrane for oily wastewater separation
Oily wastewater is one of the greatest problems in the world and needs an urgent solution. Therefore, this work describes the preparation of green ceramic hollow fiber membranes derived from waste sugarcane bagasse ash (WSBA) using phase inversion and sintering techniques. The first step in the …

Fundamental study of hydrophobic microporous membrane contactors for the recovery of insoluble oil from oil-water mixtures
Insoluble oil and water mixtures occur in many industries such as food, metallurgical, or biofuel production. In particular, as we strive to meet global energy demands, the associated risks and waste management of the oil and gas industry must be addressed. Technologies capable of separating oil …

Oil flow from compressor valve to discharge tube
Oil existence is important for compressor operation because it provides lubrication, cooling and sealing. But the discharge process of the compressor inevitably entrains some oil in the refrigerant vapor, which makes oil leave compressor and circulate in the system. For better heat transfer and …

Modeling piston skirt lubrication in internal combustion engines
… analysis of and development of a model for the oil transport and exchange of the piston skirt region and its surroundings. The new oil transport model is composed with two elements. First, the oil scraped into the chamfer region by the oil control ring during a down-stroke is tracked and its …

Biodiesel Production and Purification with a Hydrophobic Sintered Glass Filter
… was synthesized from methanol and cooking oil via a base-catalyzed transesterification reaction. Glycerol and fatty acid salts were obtained as side products via this transesterification reaction. The excess unreacted methanol was first removed by rotary evaporation, and hydrochloric acid …

Flow and separation of the oil from compressor discharge to external separator
Oil is essential for most of the refrigerant compressors, but oil circulating in the refrigeration or air conditioning systems has a side effect on the heat transfer and total efficiency. Oil separator is an important component to reduce the amount of oil circulating in the system and to keep the …

Metal oxide modified tubular ceramic membrane for the separation of oil-in-water emulsion.
Separating lower concentrations of oil-in-water (O/W) emulsion (< 250 mg/l) and smaller oil droplet size (< 20 μm) has been an industry challenge using conventional methods, including adsorption, electrocoagulation, flocculation, bioremediation, centrifugation, membranes, etc. This is mostly due to …
