... this absorption process, HMX operation is under exclusion of non-condensing gasses. Fig. 1b shows the finned tube heat exchanger used both as absorber and desorber (A/D) as well as evaporator and condenser (E/C). Dual function is possible due to the time separated processes of evaporation and absorption and the process of desorption and condensation. Both, in absorption and desorption operation, aqueous NaOH is introduced to ...

... as well as evaporator and condenser (E/C). Dual function is possible due to the time separated processes of evaporation and absorption and the process of desorption and condensation. Both, in absorption and desorption operation, aqueous NaOH is introduced to the top of the A/D spiral fin and flows down, channeled along the fin as illustrated in Fig. 1a. In absorption mode, water follows the same principle on the E/C unit whereby it is evaporated by means of low temperature heat source and in turn absorbed on the aqueous NaOH. The heat of vapor condensation as well as to a smaller part the heat of dilution is released at concentration dependent elevated temperature to the heat ...
