22 Apr 2015TL;DR: In this paper, a heat dissipation apparatus including multiple heat exchange sheets is presented, where a first path and a second path are formed between the multiple Heat Exchange sheets, and the first path includes a first countercurrent channel, a guide channel, and a first-outlet cross-flow channel; the second path includes two countercurrent channels and two inlet channels.
Abstract: A heat dissipation apparatus including multiple heat exchange sheets. A first path and a second path are formed between the multiple heat exchange sheets, and the first path includes a first countercurrent channel, a guide channel, and a first-outlet cross-flow channel; the second path includes a second countercurrent channel and a second-inlet cross-flow channel. One part of a first fluid that enters the first path enters the first countercurrent channel and mainly performs countercurrent heat exchange with a second fluid that is in the second countercurrent channel, and the other part passes the guide channel and rapidly performs cross-flow heat exchange.

TL;DR: In this paper, a rotary counter-current solid/fluid contact apparatus is provided to enhance the efficiency of adsorption, ion exchange, and regenerative heat exchange using a rotor to direct fluids to multiple stationary columns, or multiple sections of a stationary column.
Abstract: A rotary counter-current solid/fluid contact apparatus is provided to enhance the efficiency of adsorption, ion exchange and regenerative heat exchange. The counter-current apparatus uses a rotor to direct fluids to multiple stationary columns, or multiple sections of a stationary column. By the action of the rotor, counter-current flows of a fluid phase and a solid phase can be achieved for a combined adsorption and desorption cycle, or a combined heating and cooling cycle. The apparatus allows not only countercurrent solid-fluid flows based on columns in series, but also countercurrent solid-fluid flows in the length of each individual column. The apparatus does not require a turntable to rotate multiple columns.

TL;DR: In this article, an analytical expression for the minimum gas flowrate required for the design of an isothermal countercurrent gas stripper, when Henrys law (H > 1) applies and the gas and liquid streams are concentrated in the soluble gas of the binary gas mixture.
Abstract: It is presented an analytical expression for the minimum gas flowrate required for the design of an isothermal countercurrent gas stripper, when Henrys law (H > 1) applies and the gas and liquid streams are concentrated in the soluble gas of the binary gas mixture. This solution allows for a faster and more accurate result, for (GB)min, than the graphical procedure presently in use.

TL;DR: In this paper, a thin bed reactor with axial flow of reaction heat from the reaction zone to the preheat zone is considered, where the feed being supplied to the reactor at a temperature of at least 100°C below reaction temperature and being heated to reaction temperature by conductive flow of heat generated by the reaction axially through the bed countercurrent to feed flow.
Abstract: Methane is converted to higher hydrocarbons by reaction with a gaseous oxidant under adiabatic conditions in a thin bed reactor, the feed being supplied to the reactor at a temperature of at least 100°C below reaction temperature and being heated to reaction temperature by conductive flow of heat generated by the reaction axially through the bed countercurrent to feed flow. A suitable reactor has a preheat zone and a reaction zone with axial flow of reaction heat from the reaction zone to the preheat zone.
