2009-12 GEA Wiegand is specialized on gas jet scrubbers and Venturi scrubbers which are highly efficient to clean, dedust, and cool flue and process gases.

GEA Wiegand has actually delivered three Scrubber systems to remove hydrofluoric acid and hydrochloric acid from off gases produced by a periodic kiln.

The operation of the scrubbers are discontinuous depending on the certain steps of the kiln process. In one of this process steps the kiln has to be flushed with inert gases. In former times the customer has used nitrogen, which was very cost intensive.

As a process innovation GEA Wiegand has now combined the scrubbers with the kiln so that the customer can use the cooled gases out of the scrubber instead of nitrogen, which creates a lot of additional earnings.
