Summary

Thin film mode in ammonia-water absorption systems provides relatively high heat transfer coefficients and is stable during operation. However, thin film mode needs good liquid distributors. Bubble mode provides not only high heat transfer coefficients but also a good mixing effect between the liquid and the vapour. The objective of the study described was to develop a design model for a bubble absorber with plate heat exchangers, to evaluate simultaneous heat and mass transfer within both liquid and bubble and to clarify significant factors for the design of an ammonia-water bubble absorber.
