An experimental investigation of two compact counter-flow vapor generation units, for use in ammonia-water absorption systems, was conducted. The vapor generation units feature integrated desorber, analyzer, and rectifier sections. The branched tray design uses pool-boiling mechanisms in the desorption process, while the vertical column uses falling-film evaporation mechanisms. Experimental mass transfer coefficients for the desorbers of both concepts were quantified and compared with correlations from the literature, generally with poor agreement. The flooding limits of these counter-flow vapor generation units were investigated and agree well with available correlations. The experimental results from Part I of this study are used in this paper, Part II, to develop revised heat and mass transfer models that accurately predict component level performance.

对用于氨水吸收系统的两个紧凑型逆流蒸汽发生装置进行了实验研究。蒸汽发生装置具有集成的解吸器，分析仪和精馏器部分。分支塔盘设计在解吸过程中使用池沸腾机制，而垂直塔使用降膜蒸发机制。对这两个概念的解吸器的实验传质系数进行了量化，并与文献中的相关性进行了比较，通常一致性差。对这些逆流蒸气发生单元的注水极限进行了研究，并与可用的相关性很好地吻合。本文使用了本研究第一部分的实验结果，第二部分是
