Description:
The goal of this study was to perform an engineering evaluation of a new fluidized-bed adsorption technology that was developed in Japan. This technology has been licensed by Union Carbide and is now being marketed in the United States, under the name PURASIV HR Vapor Recovery System. Since this technology allows the use of nitrogen to regenerate the carbon, the need for additional steps to separate water-miscible solvents from the water may be reduced. The engineering evaluation was developed by performing field tests on a full-scale PURASIV HR unit at Polaroid Corporation, Waltham, Massachusetts. These data were supplemented by operating information from a PURASIV HR system at General Motors Corporation, Fremont, California. Capital and operating costs were then developed for both PURASIV HR and fixed-bed adsorption systems. Technical comparisons between the two types of adsorption systems were also made.
