INTENSIFICATION OF HEAT TRANSFER IN THE REFRIGERATION ZONE OF ABSORPTION COLUMNS

The intensifi cation of heat transfer in the refrigeration zone of absorption columns has been studied. It is shown that for the absorption of CO₂ by ammoniated brine it is possible to signifi cantly intensify the process of removing the heat of exothermal reaction. It has been established that the hydraulic resistance of spirally rolled pipes is 1.5 times less than that of pipes with discrete arrangement of annular diaphragms. Data are obtained on K/Ksm and F/Fsm depending on the spacing between spirally rolled turbilizers S/D, and the optimal regions were determined in the range of values S/D = 1.0–1.4. The effi ciency of pipes with spirally rolled turbilizers has been demonstrated.
