TL;DR: In this article, the effect of cationic fluxes on separation was also studied for the ternary system NaCl-KC1-H2O, where the number of porous membranes was varied from one to four and a comparison between three different kinds of cell arrangements was made, and the present method was found to be the most attractive for practical purposes.
Abstract: Countercurrent electrolysis in a cell wehre porous membranes have been connected in series with ion-exchange membranes has been studied experimentally for the ternary system NaCl-KC1-H2O. The number of porous membranes was varied from one to four, and the effect of cationic fluxes on separation was also studied. A comparison between three different kinds of cell arrangements was made, and the present method was found to be the most attractive for practical purposes.

TL;DR: In this paper, a closed circuit combustion gas loop and closed circuit liquid heat transfer loop are circulated countercurrent to one another so that maximum heat transfer efficiency is achieved and exhaust emissions are reduced to a minimum.
Abstract: Furnace structures having smoke and gas return are disclosed The structures have a closed circuit combustion gas loop and a closed circuit liquid heat transfer loop The two loops are circulated countercurrent to one another so that maximum heat transfer efficiency is achieved and exhaust emissions are reduced to a minimum

TL;DR: In this article, different temperature control schemes for the COPROX stage of a 5-kW fuel cell system were analyzed, and the best choice for temperature control was the series of adiabatic reactors with interstage heat exchange.
Abstract: Different temperature control schemes for the COPROX stage of a 5-kW fuel cell system were analyzed. It was found that, among the schemes proposed, i.e., co- and countercurrent heat exchange, single adiabatic reactor and series of adiabatic reactors with interstage heat exchange, the best choice for temperature control was the series of adiabatic reactors with interstage heat exchange. This scheme represented the best way to keep the average temperature around 443 K, which was found to be the most suitable temperature for selectivity towards CO oxidation. If hydrogen is produced from ethanol steam reforming, the heat withdrawal can be carried out by the water/ethanol reformer feed mixture, thus contributing to the energy integration of the overall system.
