CLEANING-SYSTEM CONCEPT FOR EXHAUST-AIR F ROM RUBBER PRODUCTION

This paper presents a process permitting to design exhaust-air Cleanin g systems for rubber outlets. The procedure is based on determining th e concentration of gaseous organic compounds (total carbon) in relatio n with the exhaustair flow which is directed, in this case, through a cooling section where it is cooled down in predetermined stages so as to reach the saturation concentration values. Dew point curves can be derived from the parts of values of concentration/exhaust-gas temperat ure. When the dew point curves are known, the maximum exhaust-gas temp erature being necessary can then be specified, depending on the limit concentration required.
