Efficient gas absorption depends on the following:
1. Intimate
2. Efficient Heat Transfer
In BISFFA Cylindrical block type Falling Film Absorber in which both gas to be absorbed and absorbing liquid flow co-currently downward with the extraction of heat by circulation of cooling water in the shell. The absorbing liquid is circulated through a tank till desired concentration is achieved. Absorption of HCl is an Exothermic reaction so cooler is required in absorption process but in BIS design both absorption and Cooling Takes place in the same BIS block and unit taking care of the exothermic during absorption, thereby achieving
