    Abstract: Molecular sieve zeolites are incorporated in the inflator device to assist in the inflation of airbags in passenger vehicles. The pre-loading of the molecular sieve zeolites with gases such as air or nitrogen or carbon dioxide provides for rapid airbag inflation and following inflation, additionally provides the remediation of at least a portion of the toxic waste gases generated by the exploding inflator device. Molecular sieve zeolites, particularly zeolites X, having been exchanged with lithium or calcium, provide high-capacity gas storage and enhanced toxic waste gas adsorption. The use of molecular sieve zeolites reduces risk of injury to occupants of vehicles from exposure to hot, toxic waste gases following airbag deployment.

    Abstract: The present invention is a process for controlling a sorption cooling or heating process which employs an adsorption zone in fluid communication with a refrigeration circuit to pass desorbed vapor upon heating to a condenser and to adsorb refrigerant vapor from an evaporator when cooled. The process is cyclic and comprises heating the adsorption zone during a desorption step and cooling the adsorption zone during an adsorption step. The heating and cooling of the adsorption zone wherein a heat exchange zone is in intimate indirect thermal contact with the adsorption zone is provided during a cyclic process by alternating the flow of a working fluid at a hot source temperature or a working fluid at a cold source temperature through the heat exchange zone to provide the heating and cooling. It was discovered that by conserving hot working fluid at or above a reference temperature in a hot working medium reservoir, fluctuations in the heating requirements at the hot source can be minimized and significant cost savings could be achieved. The present invention can provide significant benefits in the refining and petrochemical process industry where product streams from catalytic reactions at elevated temperatures must be cooled to ambient conditions for storage or transport.

    Abstract: A process and a control system are disclosed for continuous cooling of a condensable process stream by the integration of a sorption cooling section for producing a chilled stream therewith. The condensable process stream is cooled with a cooled hot exit stream from the sorption cooling section to provide a hot working fluid stream to desorb an adsorption zone in the sorption cooling zone. A cold working fluid stream comprising a condensed portion of the condensable stream is passed to the sorption cooling section to facilitate adsorption in another adsorption zone in the sorption cooling section and a warm exit stream is withdrawn. The hot exit stream and the warm exit stream are cross-exchanged to smooth out the temperature variations which reduce the size and operating cost of producing the chilled stream. Potential damage to equipment and variation operations can be avoided by comparing the pressure of the condensable process stream to the pressure of the condensed portion and admixing a portion of the condensable stream with the condensed portion. The process provides significant economic benefits operating cost savings in refinery and petrochemical applications where fractionation column overhead vapors or flue gases are available at waste heat temperatures above about 80.degree. C. (176.degree. F.) such as fluid catalytic cracking, crude phenol fractionation, benzene, toluene, xylene, ethylbenzene, and cumene columns and naphtha splitter columns.
