BOROSILICATE GLASSWARE - HCL Absorber

 

The Glass has provided to be an unrivalled material of construction for plant handling Hydrochloric acid in all concentrations. In the Chemical industry the absorption of hydrogen chloride is a typical example where glass can be used to the best advantage. Function : Hydrogen chloride feed gas is being allowed to enter from the inlet provided on 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 principle involved is falling film absorption which have :

• Ability to absorb large loadings of gas flow.
• Capacity to produce strong acid with minimum vent losses, since absorption is effected at a low temperature.

Absorber consists of a vertical Shell andTube Heat Exchanger incorporating economical design considerations. Compactness and light weight are the additional features.
