Patent number: 9919258Abstract: A pressure swing adsorption process for producing a gas stream enriched in a compound X from a feed gas stream is provided. The process includes at least 2 adsorbers, with each adsorber being subjected to a pressure cycle having a high pressure and a low pressure. The process includes adsorption at the high pressure with production of the gas stream enriched in compound X; then depressurization; then elution at the low pressure; and finally repressurization to the high pressure. The elution gas is made up fractions of gas stream resulting from the depressurization of an adsorber and the gas stream enriched in compound X. The pressure cycle has a phase time corresponding to the duration of a pressure cycle divided by the number of adsorbers and the fraction of the gas stream enriched in compound X is determined as a function of the phase time.Type: GrantFiled: September 30, 2014Date of Patent: March 20, 2018Assignee: L'Air Liquide, Société Anonyme pour l'Etude et l'Exploitation des Procédés Georges ClaudeInventors: Christian Monereau, Yann-Pierrick Lemaire, Elise Renou, Louis Toulemonde

Publication number: 20050005766Abstract: The invention concerns a calcium and barium cation-exchanged zeolitic adsorbent for use in a process for purifying and or separating a gas or gas mixture, in particular air, so as to eliminate impurities contained therein such as hydrocarbons and nitrogen oxides (NxOy), preferably, among ethylene, acetylene, butane and propane. Preferably, the adsorbent is an X or LSX zeolitic exchanged to between 10 and 90% with calcium cations and to between 10 and 90% with barium cations, the sum of barium and calcium cations present representing at least 20% of the exchangeable cations. The purification process is of the TSA type. Advantageously, CO2 impurities and/or water vapour contained in the gas stream are eliminated as well. The invention also concerns a method for making such an adsorbent.Type: ApplicationFiled: October 16, 2002Publication date: January 13, 2005Inventors: Serge Moreau, Elise Renou, Claire Szulman
