Detergent zeolite complex "Ceosil", Tallinn, Estonia

Abstract

The IGPC Engineering Department, together with the "Birac", Zvornik Engineering Department designed basic projects for detergent zeolite production, using waste flotation sand and hydrates. Several projects were completed: technological, machine, electrical, automation. On the basis of these projects, production plant in Tallinn, Estonia was constructed, with a capacity of 100,000 t/y from 1989. to 1993. This plant became the biggest producer of detergent zeolite in the world.Several goals were realized by designing the "Ceosil" plant. Waste flotation sand was used and detergent zeolite was produced in a market which is not properly supplied with this zeolite. The product meets all quality demands, as well as environmental regulations. The detergent production process is fully automatized and the product has uniform quality. There is no waste material in detergent zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during start - up, and repairs.
