    摘要： A modular and compact adsorbent bed structure is disclosed for use in an adsorption-based gas separation plant. The conventional adsorbent bed in a gas separation plant is replaced with a plurality of modular adsorbent bed units connected to make the adsorbent bed structure. Modular adsorbent bed units of this invention provide higher capacity of product per unit volume of adsorbent material (i.e., increased adsorbent utilization) as compared to that obtained from conventional adsorbent beds. The modular design requires lower fabrication costs; is easier to transport; has less maintenance and repair requirements; and is easier to load with adsorbent material.

    摘要： The invention comprises a rotary valve having first and second inlet/outlet flow passages, as well as one or more (preferably between 6 and 8) flow ports. The valve has a plurality of positions simultaneously interconnecting the first and second flow passage to selected flow ports. In a preferred embodiment, the valve has a housing and the flow ports are disposed on outer peripheral walls of the housing. The valve may further include an internal rotary plug that is rotatable about a longitudinal axis to move between the positions, and containing openings to connect the flow passages to the flow ports. The plug may be divided into two chambers in the valve which may or may not be moved independently of each other. The valve may further include a movable seal between the housing and the internal plug member which is retractable to permit freer movement of the plug.

    摘要： A vacuum pressure swing adsorbent (VPSA) system and method for separating a component from a fluid mixture and including a fluid source for introducing the mixture into the system and a supply apparatus for collecting the separated component. A pair of adsorbent bed vessels is interposed between the fluid source and the supply apparatus to adsorb and desorb a predetermined component under respective adsorption and desorption pressures characterized by a low pressure ratio and relatively high desorption pressure values. Implementation of a single-stage vacuum device made possible by the use of the high desorption pressure, results in further reduction in both equipment and operating costs.

    摘要： A pressure swing adsorption process for the recovery of oxygen from air improves upon a prior art process by depressurizing the adsorbent bed within an adsorbent vessel to an intermediate pressure by releasing void space gas from the product end of the vessel to a low purity oxygen tank while concurrently evacuating the adsorbent vessel from the feed end. This action enables an increased speed of depressurization and a reduction of the cycle time. Further, the adsorbent bed is repressurized to an intermediate pressure from the product outlet end with gas from the low purity oxygen tank, while concurrently pressurizing the adsorbent vessel from the input feed end. This action increases the load time fraction for a feed/vacuum blower. Further, oxygen is introduced to the product end of the adsorbent bed vessel from a high purity oxygen tank (which provides product to downstream applications) while concurrently, air is introduced to the feed end of the adsorbent bed within the vessel. This enables an increased speed of increase in pressure in the bed from the intermediate desorption pressure. Next, a reduction in pressure ratio during the cycle elevates the pressure within the desorption vessel to approximately 7 psia, thereby reducing the evacuation requirements placed on the feed/vacuum blower. The above actions enable achievement of efficiency improvements on the order of 10%.

    摘要翻译： 通过从现有技术的方法回收氧气的变压吸附方法通过将吸附剂容器内的吸附剂床减压到中间压力，通过从容器的产品端释放出空隙气体到低纯度的氧气罐，同时 同时从吸入端排出吸附剂容器。 该动作能够提高减压速度和减少循环时间。 此外，吸附床用来自低纯度氧气罐的气体从产品出口端再加压到中间压力，同时从输入进料端加压吸附剂容器。 该作用增加了进料/真空鼓风机的载荷时间分数。 此外，氧气从高纯度氧气罐（其向下游应用提供产品）引入吸附床容器的产品端，同时空气被引入到容器内的吸附剂床的进料端。 这使得能够从中间解吸压力提高床中压力的增加速度。 接下来，循环期间的压力比的降低将解吸容器内的压力提高到约7psia，从而降低了对进料/真空鼓风机的排气要求。 上述措施可以实现10％的效率提升。

    摘要： The present invention generally relates to the attenuation of vacuum blower noise using a silencer. More particularly, the present invention relates to a low-cost, reliable and efficient silencer for reducing noise levels in adsorption-based gas separation plants from the discharge of the vacuum blower or from the feed blower inlet, to about the 90 dBA level or less, at the silencer opening to the atmosphere. The silencer includes at least one reactive chamber(s) to attenuate low frequency pulsations and at least one absorptive chamber(s) to attenuate noise at medium to high frequency noise.

    摘要： A VPSA apparatus includes a first adsorbent bed and a second adsorbent bed, a feed blower for providing a flow of a gas mixture at about atmospheric pressure to the beds, and a vacuum blower for removing a flow of gas therefrom and venting the gas to a space at atmospheric pressure. The VPSA process causes the first adsorbent bed to be poised for evacuation by the vacuum blower and concurrently, the second adsorbent bed is under vacuum conditions and is poised for pressurization by the feed blower. A single motor is coupled by a common shaft to both the feed blower and the vacuum blower and operates both. A conduit/valve arrangement is operative during at least a portion of a process time when the adsorbent beds are in pressurizing/evacuation states, respectively, to couple the feed blower to the second adsorbent bed when at vacuum and for concurrently coupling the vacuum blower to the first adsorbent bed which is to be evacuated. The feed blower is thereby caused to operate in a gas expansion mode and imparts expansion energy, via the common shaft, to the vacuum blower. During idling conditions, a valve-conduit system is controlled to enable significant reductions in pressure rise across the feed and vacuum blowers.
