RESUME – Vinyl Chloride (VCM) is the main monomer used in the production of polyvinyl chloride. Classified as a toxic and carcinogenic agent, VCM must be thoroughly separated and recuperated from the resulting polymer. A literature review on adsorbent materials was performed and a temperature and pressure swing adsorption (TPSA) system was developed for the equilibrium adsorption separation of VCM and nitrogen (N2). Using a 1-dimensional mathematical model, a 7-step, 2-column TPSA system was designed to treat an industrial scale 40:60% VCM/N2 mixture and produce a 95% (v/v) VCM rich stream and a N2 stream with a VCM content of 8 ppm (w/w). A process comparison and optimization was also performed to study the effects of the step configuration and duration on the system performance.
