Hydrogen Chloride Gas Absorber works using two methods like adiabatic absorption that is suitable when the inerts like air, phenolic compounds etc. The Hydrogen Chloride Absorber also utilises isothermal absorption method which is ideal when inerts like air, phenolic compounds etc. The Gas Absorber allows HCl gas to be economically absorbed forming hydrochloric acid of 30% [w/w] concentration, which can be re-used, in the main process. Hydrogen Chloride Gas Absorber can be availed in different specifications to cater to specific requirement.
