More Information
Summary:A process for purifying high-temperature reducing gases containing sulfureous contaminants including hydrogen sulfide and carbonyl sulfide with an absorbent, said process characterized in that at least three reactor towers which are filled with an absorbent are used, and said process comprises the three steps of absorption, regeneration, and reduction, and during in a part of operation two reactor towers are connected in series so as to carry out regeneration, and O2 concentration can be controlled separately for each regenerating reactor tower in the regeneration step, and steam can be supplied so as to prevent excessive reduction of the absorbent from occurring in the reduction step. The life of the absorbent can be extended and operational costs may be reduced.
