Extension of Ecologization Concept to Cleaner Production

By William Zadorsky ()

ABSTRACT. The systems analysis of chemical processing revealed the importance of integration, selectivity and flexibility. These considerations will minimize wastes not by recycling but rather through a more nearly complete utilization of resources in a chemical processing unit.

Following are some of the conclusions:

(1) Minimizing processing time and reagent surplus mostly results in increased selectivity and reduced byproduct yield.

(2) Recuperation, that is closed-loop flow of materials and energy, brings synthesis mode closer to an ideal, so that the side reactions are decelerated.

(3) Combining synthesis and separation through heterogenizing removes the target product from the reaction zone at the moment of its formation and thus reduces byproduct yield.

(4) Adaptable processes and apparatuses ensure reliable operation of a system using its "intrinsic" potential. This minimizes abnormal discharges.

DEGREE OF COMMERCIALIZATION. The development was tested and implemented at some chemical plants in the CIS.

TECHNICAL DATA AND COST PERFORMANCE. The emissions were reduced tenfold and more while the operations became more cost-effective.

MARKET PENETRATION. Our expertise is offered by way of consulting for projects aimed at upgrading specific installations.

KEY WORDS. Cleaner production, environmental protection, pollution abatement, chemical processing, energy conservation, materials conservation, chemical reactors, product yield, side reactions, flexible manufacturing systems, recovery, closed loop cycle, adaptive systems.
