组合的热量和质量交换装置的热力学平衡
摘要：
一种载气混合物被引导穿过一种组合的热量和质量传递装置(12，14)中的一个流体流动路径(16，18)，该组合的热量和质量传递装置可以在亚大气压下运行。使热量和质量通过以下方式从该载气混合物传递或传递至该载气混合物：与包括呈液体状态的一种可蒸发的组分的一种液体组合物相互作用以便经由蒸发或冷凝来实质性地改变该载气混合物中的可蒸发的组分的含量。该载气混合物的质量流率通过从该流体流动路径中的至少一个中间位置抽提/注入(60，62，64)该载气混合物来改变，和/或该液体组合物的质量流率通过从该流体流动路径中的至少一个中间位置抽提/注入该液体组合物来改变。对该载气混合物或该液体组合物的流进行调节以降低平均局部焓夹点。
摘要（英）：

A carrier-gas mixture is directed through a fluid flow path in a combined heat and mass transfer device operating at a sub-atmospheric pressure. Heat and mass are transferred from or to the carrier-gas mixture via interaction with a liquid composition that includes a vaporizable component in a liquid state to substantially change the content of the vaporizable component in the carrier-gas mixture via evaporation or condensation of the vaporizable component. The mass flow rate of the carrier-gas mixture is varied by extracting or injecting the carrier-gas mixture from at least one intermediate location in the fluid flow path, and/or the mass flow rate of the liquid composition is varied by extracting or injecting the liquid composition from at least one intermediate location in the fluid flow path; and the flow of the carrier-gas mixture or the liquid composition is regulated to reduce the average local enthalpy pinch in the device.
