Abstract

The agent contains a scaling inhibitor and a water-soluble polymer with a high molecular weight. The weight ratio of scaling inhibitor to polymer is 1:10 to 10:1. In order to inhibit scaling and deposit formation in gas scrubbers, a concentration of the agent of at least 0.01 parts by weight/million parts by weight is maintained in the aqueous gas scrubbing medium. The inexpensive agent makes possible effective prevention of sedimentation or deposit formation in gas scrubbers in an economical manner within a wide pH range. The necessity for mechanical cleaning of the scrubbing plant is greatly reduced. [GB1532391A]
