Abstract

An innovative hollow-fiber-contained liquid membrane permeator is being investigated for removal of SO2 and NO from the flue gas of coal-fired boilers. Various liquid membranes were tested in this work to determine SO2 and NO permeabilities and selectivities. Using a solution of a metal chelate complex as the liquid membrane, 70 to 90 percent of the SO2 and 50 to 75 percent of the NO were simultaneously removed from the flue gas. For SO2 removal alone, water and solutions of either sodium sulfite or sodium bisulfite showed excellent results. Further research is required to optimize the design and operating conditions of this system for future applications.
