These particular types of exhaust gases and residual liquids with high or low calorific values are generally produced in the pharmaceutical, chemical and petrochemical industries. A special case is the incineration of saline exhaust gases or residual liquids, for which Dürr and Caloric now offer joint solutions. Here, salt slag is formed in the combustion chamber of an air pollution control system and must be removed. This removal is generally achieved by means of a vertical arrangement of the combustion chamber with subsequent quench. The salts are dissolved in water, and insoluble constituents are collected and removed by a suitable system. Special attention must be paid to the design of the lining in case of alkaline salts because these salts attack the lining and destroy it over time.
This agreement combines Caloric’s great know-how with Dürr’s global presence and great market penetration. The collaboration is initially agreed for a period of five years.
