COST-ANALYSIS OF OPTIMUM HYBRID SYSTEMS FOR MEMBRANE CONCENTRATION AND CONDENSATION OF VOLATILE ORGANIC-COMPOUNDS

For a hybrid system that includes a membrane module and a condenser op timisation calculations were carried out. These calculations enable th e optimum values of permeate pressure and the membrane surface area to be evaluated for the given parameters of the gas at the inlet to the membrane installation. The solutions proposed for the system studied l ead to a decrease in the total annual cost, the cost of solvent recove ry and the consumption of electric power.
