| Summary: | The IGPC Engineering Department designed basic projects for detergent zeolite filtration plant, using technology developed in the IGPC laboratories. Several projects were completed: technological, machine, electrical, automation. On the basis of these projects, a production plant with a capacity of 75,000 t/y was manufactured, at "Zeolite Mira", Mira (VE), Italy, in 1997, for increasing detergent zeolite production, from 50,000 to 100,000 t/y. The main goal was to increase the detergent zeolite production capacity. The technological cycle of the filtrate was closed, and no effluents emitted, and there is no pollution. The detergent zeolite filtration process is fully continuous, by which a significant improvement in zeolite production was achieved, both in unification of quality of the product and in simplifying production. This process is fully automatized, and the product has uniform quality. The production process can be controlled manually, which is necessary during start-up, and repairs. By installing additional process equipment (centrifugal pumps, a vacuum system and belt filter) technological bottlenecks were overcome by adjusting the work of centrifugal pumps and belt filter, and also by optimizing the capacities of process equipment.
