摘要: A cyclic process for the separation of water and carbon dioxide contaminants from a feed gas stream by adsorption on molecular sieve adsorbents subsequent regeneration is disclosed. Adsorption CO 2 accomplished passing through first second adsorbent zones, containing adsorbents. Water adsorbed in zone primarily zone. Regeneration zones sequential steps of: (1) introducing heated intemediate countercurrent direction until exiting reaches approximately 250° F. to 350° F.; (2) discontinuing introduction cool at inlet sequentially thereby pushing thermal pulse continuing flow are cooled operating temperature.
