Comparison of binary mixture heat and mass transfer analysis with single-component heat and mass transfer analysis in the design of GAX absorber/desorber.

Author(s) : CAO J., CHRISTENSEN R. N.

Summary

The GAX cycle is an elegant way of achieving higher effect performance with single-stage configuration. One of the key components of the GAX cycle is the absorber/desorber heat exchanger, which carries out internal heat recovery. The paper investigated two different models for the design of an absorber/desorber in the GAX system. The results show that about 57% of extra heat transfer area would be needed under the case being investigated if the fluid is considered as a binary mixture rather than a single-component fluid. The paper provides a basic guideline for designing a properly sized GAX absorber-desorber.
