Representatives of GEA Bischoff presented an overview of GEA Bischoff and the types 

of emissions control work their company performs, including their work with cement 

manufacturing plants. Recent scrubber installations include a Lafarge cement plant in Dunbar, 

GB and one at Lehigh in Mason City, Iowa. Designs and issues in the application of scrubbers 

for the control of HCl, SO2 and mercury were discussed. 

In addition to the cement industry, Bischoff provides emissions control solutions for the 

glass, catalytic cracking, iron and steel, and energy recovery industries. 

Information on their control technologies is attached. 

Other comments from the meeting: 

• GEA has installed 7 wet scrubbers in the cement industry. The most recent 

installation uses EPA dust and raw mill dust as the reagent (Dunbar, Scotland). 

• Recently installed a low dust SCR system after an ESP/Bag Filter – Waldorf 

Cement – it begins operation next year.

Module includes an organic working

fluid in a closed circuit.

Electric power is produced in a

generator powered by a low pressure

turbine.

Being a compact and self-contained

unit, the ORC module only requires

small space.

Opposed to steam systems,
