HCl Absorption System

Additional Details

We are offering to our clients HCl Absorption System which comprises an isothermal falling film type absorber and adiabatic tail-gas tower with a recirculation pump. The isothermal absorber can be in Poly block or shell and Tube Type.

The salient features are:

• Special distribution block
• Wire type distribution arrangement for equal distribution of process, Water and formation of a uniform liquid film in all holes
• Suitable for gases coming from batch-process. 

The system works in the following steps:

• HCl gas and the water film travel co-currently and the gas gets absorbed into the liquid film.
• The heat of absorption generated is continuously removed with the help of cooling / chilled water supplied on the service side.
• The bottom product from the main absorber is 30 to 33 %
• Hydrochloric acid unabsorbed gases from the absorber are absorbed in the tail gas tower with packing bed of ceramic / graphite packing media.
• User can achieve a turn-down ratio of zero maximum up to 100% with the help of proper recirculation.
