19 Nov 1971TL;DR: In this article, a method for selectively plugging a soil or the first interval of a porous underground formation and controlling the occurrence of said plugging by injecting into the formation a mixture containing brine, a volume of surfactant, sodium hypochlorite and a polymeric elastomer latex having a definite particle size was proposed.
Abstract: A method for selectively plugging a soil or a first interval of a porous subterranean formation and controlling the occurrence of said plugging by injecting into the formation a mixture containing brine, a volume of surfactant, a volume of sodium hypochlorite and a polymeric elastomer latex having a definite particle size.

TL;DR: In this paper, the authors proposed an alternative approach for cases when the above requirements are not met, which consists of extracting brine from the storage formation and then re-injecting it so that it mixes with CO2 at depth in the injection well.

TL;DR: In this paper, the effect of nanoparticle combination, shape and size on heat transfer area, pump work, the ratio of heat transfer coefficient to pressure drop, coefficient of performance, performance index, thermal performance factor and exergetic efficiency has been examined theoretically.
Abstract: Brines (ethylene glycol, calcium chloride, propylene glycol and potassium acetate)-based hybrid (combinations of alumina, copper oxide, silica and titania with copper nanoparticles) nanofluids have been used as a secondary refrigerant to improve the heat transfer characteristics of the plate evaporator for milk chilling. Effect of nanoparticle combination, shape and size on heat transfer area, pump work, the ratio of heat transfer coefficient to pressure drop, coefficient of performance, performance index, thermal performance factor and exergetic efficiency has been examined theoretically. Copper oxide–copper hybrid nanofluid gives superior performance, while silica–copper hybrid nanofluid performs well in terms of exergetic efficiency. The maximum decrease in effective heat transfer area (5.9%) is found for propylene glycol brine-based copper oxide hybrid nanofluid. Percentage change in heat transfer area and performance index reduces with an increase in the particle size and is maximum for alumina–copper hybrid nanofluid. However, thermal performance factor increases with particle size. Brick-shaped particles show maximum changes in heat transfer area and performance index, while platelet-shaped particles show worse performance. The study reveals that the nanoparticle shape has a strong influence on the plate heat exchanger performance due to a significant deviation in surface area-to-volume ratio.

TL;DR: In this paper, the authors used CFD ANSYS fluent software to simulate the freeze desalination process and showed that the achieved average ice salinity in the second stage of freezing process was below 0.05% which is regarded as good quality drinking water; also freezing at 225'k temperature produced the largest pure ice volume.

TL;DR: In this article , a nanofiltration membrane with exclusive Li+ transport channels was designed and prepared through facile interfacial polymerization, in which polyethyleneimine (PEI) bonded with 15-crown-5 ether (15C5) through hydrogen interaction was selected as the aqueous monomer and reacted with trimesoyl chloride (TMC).
