Abstract

A process for cleaning filtering separators used in dry chemisorption systems. A maximum of 1-2% of the total filter area is in the cleaning process at any given time, to provide for utmost efficiency of the chemisorption activity. In the cleaning stage, the separators are cleaned by shock devices or similar means and are coated with fresh chemisorption mass before being returned to the chemisorption system.
