| Abstract: | The effects of trichloroethylene (TCE) removal by using several kinds of adsorbents under different regeneration conditions have been investigated.A new PTSA (pressure and temperature swing adsorption)process of removal and recovery TCE is proposed,which use heated refine gas to regenerate adsorbent.The newly introduced process proves to have following characteristics:(1)the investment and operation cost is low;(2)the process is simple;(3)the exiting content of TCE is low,therefore,there is almost no environmental pollution. |
