摘要： A process and a system for purifying gas, such as air, before cryogenic distillation, in which at least one energy parameter, chosen from the flow rate of the regeneration gas entering and/or leaving at least one adsorber, the duration of the regeneration step and the regeneration temperature of the regeneration gas entering at least one adsorber, is controlled, modified and/or regulated depending on at least one operating condition chosen from the pressure of the gas to be purified entering and/or leaving at least one adsorber, the flow rate of the gas to be purified entering and/or leaving at least one adsorber, the temperature (Ta) of the gas to be purified entering at least one adsorber and the content of impurities contained in the gas to be purified entering at least one adsorber and depending on the thermal profile of the heat front output by at least one adsorber at the end of regeneration.

摘要： Systems and methods are disclosed for a gas production system to efficiently maintain a pressure of a gaseous output stream within a tight pressure range when the system changes normal operation to backup operation. In one preferred embodiment, during normal operation a backup vaporizer is kept in cold standby by directing a small portion of a liquefied gas stream away from the main heat exchanger to the backup vaporizer. In this way, the backup vaporizer is able to respond immediately to a shutdown of the main gas production system. During normal operation, the output of the backup vaporizer is recombined with the gaseous output stream to any avoid loss of product thereby increasing efficiency.
