PROCESS FOR REMOVING AND RECOVERING VOLATILE ORGANIC SUBSTANCES FROM INDUSTRIAL WASTE GASES

摘要

A process for removing and recovering volatile organic substances from industrial waste gases by adsorption on to solid adsorbents and desorption by hot inert gas circulating in a closed cycle, carried out continuously or intermittently. According to the new process, the volatile organic substances are recovered from the inert desorption gas partly by condensation by means of cooling, and partly by readsorption on to solid adsorbents.
