Hydrogen Chloride Feed Gas is being allowed to enter from the inlet provided o the upper end of Absorber. This gas falls down along with the water inside the Vertical Parallel Glass Tubes. This arrangement provides more effective absorption as cooling of dilute acid and absorption of Hydrogen Chloride Gas are taking place simultaneously. It has got more solubility in water at lower temperature. In this way Absorber work as a number of water cooled wetted wall columns in parallel.
The basic principles involved in Falling Film Absorption are:
Absorber consists of vertical Shell & Tube Heat Exchanger incorporating economical design considerations. Compactness and light weight are the additional features.
