| Abstract |
Research has been performed on the use of polymeric interfaces for in situ continuous stack monitoring of gaseous pollutants. Permeabilities of candidate interface materials to SO2 were measured at temperatures from ambient to 200C, and the results were used to design interfaces for field tests. A portable field monitoring system was constructed and used to carry out SO2 monitoring runs in two SO3 absorption tower stacks, and in oil-fired and coal-fired power plant boiler stacks. The results were in excellent agreement with data obtained by standard wet chemical methods. The SO2 concentrations in the sample gases varied linearly with the concentrations in the stack; water vapor, acid mist, and particulates in the stack gases had no effect on the interface performance; and fluctuations in the stack SO2 concentration were mirrored rapidly and accurately in the measured responses. The results suggest the potential value of in-situ polymeric interfaces for continous monitoring in stack environments too dirty or corrosive for conventional devices to be used. |
