摘要： Heat generated by the first stage compressor while it is running (either loaded or unloaded in the recycled purge air dryer system is recaptured by a stream of dried, cool system air drawn off of the outlet of a online drying tower in an air compressor system via a purge heat exchanger placed after the first stage compressor. The dried, hot air is used help regenerate the offline tower. This regenerating, pressurized, and heated purge air is then cooled in its passage across or through the desiccant in the regenerating tower. It then reenters the main airflow at the outlet of the first stage air compressor as wet cool pressurized purge air. This process is completely closed loop within the system, achieving zero air loss, and avoiding dew point spikes, increasing the efficiency of the air compressor system.

摘要： The strongly adsorbed component of a gas mixture is produced in enhanced purity and yield by novel PSA cycles. The basic steps of the cycles include an adsorption vessel prepressurization step, a cocurrent nonadsorbed gas production step, a cocurrent purge step with strongly adsorbed gas product and a countercurrent depressurization step which produces the strongly adsorbed gas product that is used in the cocurrent purge step. In addition to the basic steps, a first depressurization equalization step precedes or follows the cocurrent purge step and a corresponding first pressurization equalization step follows the countercurrent depressurization step. The cycle optionally includes one or two depressurization equalization steps before the cocurrent purge step and one or two corresponding pressurization equalization steps after the first pressurization equalization step.

摘要： An ozone containing gas stream is produced from oxygen by subjecting oxygen to an electric discharge and the ozone is then adsorbed on to a solid adsorbent, such as zeolite, the oxygen containing stream leaving the adsorbent is recycled to the ozonising process. Periodically, oxygen adsorbed on the adsorbent is desorbed by co-currently passing a purge gas over the adsorbent and the desorbed oxygen is also recycled to the ozoniser. Lastly ozone is desorbed from the adsorbent by a counter-current flow of purge gas and used in an ozone demanding process.

摘要： A process for the treatment of a gaseous mixture by adsorption with variable pressure, in an adsorption installation comprising at least one adsorber. For each adsorber, there is a succession of steps defining an adsorption phase, a regeneration phase for the adsorbent comprising a depressurization step, and a pressure increase phase. The passage from one phase to the following comprises switching of at least one valve between open and closed positions. At least one valve switching is carried out according to a programmed progressive slope to control a first cocurrent decompression stage of the adsorber with transfer of gas toward a lower pressure portion of the installation. The transferred gas is sent, for at least partially balancing pressure, to another adsorber in a pressure increase phase.

摘要： A process and apparatus for the dehumidification and VOC odor remediation of an air stream withdrawn from the passenger compartment of a transportation vehicle is disclosed which employs a continuously rotating wheel support and adsorbent selective for the adsorption of water and VOCs. The wheel is coated with zeolite adsorbent selected from the group consisting of zeolite Y-74, zeolite Y-84, zeolite Y-85, a low cerium rare earth exchanged zeolite Y-84, a rare earth exchanged zeolite LZ-210 and mixtures thereof. A surprisingly significant increase in the thermal efficiency is possible as a result of the lower regeneration temperature of the adsorbent and the use of novel process steps.
