The present disclosure relates to systems and methods useful for providing one or more chemical compounds in a substantially pure form. In particular, the systems and methods can be configured for separation of carbon dioxide from a process stream, such as a process stream in a hydrogen production system. As such, the present disclosure can provide systems and method for production of hydrogen and/or carbon dioxide.

The present invention relates to a cold box cycle which allows for independent control of the heat supplied for reboilers associated with the separation columns. More specifically, the invention relates to the tight control of the hydrogen removal separation, thus avoiding the possibility of excess reboiling in this separation. Optimal reboiling also results in a lower temperature of the hydrogen depleted liquid from this separation. As this stream is used to provide a portion of the cooling at the cold end of the primary heat exchanger, lower temperatures facilitate cooling of the incoming syngas feed, reducing carbon monoxide (CO) losses into the crude hydrogen stream from the high pressure separator. Lower CO in the crude hydrogen allows for smaller hydrogen purification equipment.

A moderate pressure nitrogen and argon producing cryogenic air separation unit is provided that includes a three distillation column system and turbine air stream bypass arrangement or circuit. The turbine air stream bypass arrangement or circuit is configured to improve argon and nitrogen recoveries in select operating modes by optionally diverting a portion of the turbine air stream to a nitrogen waste stream circuit drawn from the lower pressure column of the cryogenic air separation unit such that the diverted portion of the turbine air stream bypasses the distillation column system.

The present disclosure provides a sterilization exhaust gas treatment system, which may include a gas liquefaction recovery system, a pressure swing adsorption recovery system, a reaction system, a temperature swing adsorption recovery system, a hydration system, a recovery and storage system, and a wastewater treatment system. The gas liquefaction recovery system, the pressure swing adsorption recovery system, the reaction system, the temperature swing adsorption recovery system, and the hydration system may be fluidly connected in sequence through first connecting pipes. The gas liquefaction recovery system, the pressure swing adsorption recovery system, and the temperature swing adsorption recovery system may each be fluidly connected to the recovery and storage system through second connecting pipes. The hydration system may be fluidly connected to the wastewater treatment system through wastewater pipes. The present disclosure also provides a method for treating ethylene oxide-containing sterilization exhaust gas using the sterilization exhaust gas treatment system.
