- the adsorbent is introduced dry as a powder in the exhaust gas.
- the introduction of a dry powder as an adsorbent makes it possible to increase the enthalpy which can be used in the context of thermal decoupling and thus increases the efficiency of the overall system. Further positive effects result by saving any process equipment for liquid supply and disposal.
- the exhaust gas temperature is also greater than 250 ° C in the desulfurization and dedusting in an exhaust gas purification filter.
