摘要：本发明公开了一种变压吸附法，此法用单级吸附床实现了双组分气体的纯化。吸附床在压力下通入气体混合物，此混合物的某些组分比另外一些组分容易被吸附。本方法使吸附床两极分化，结果吸附床的一端含有易吸附组分。而另一端含有难吸附组分。当吸附床吸附了气体，它两端就同时减压，因而从两端分别回收了被分离组分。

摘要： An apparatus and process for controlling the opening and closing of valves in lines interconnecting a plurality of adsorbers in a cyclically operating pressure-swing adsorption apparatus includes a common pneumatic signal line associated with all the valves of a single line. An electrical signal supply provides an electronic signal to a current-pressure transducer for converting the electronic signal to a pneumatic signal transmitted through the common pneumatic signal line. Transmission of the pneumatic signal to the valves is controlled by three-way magnetic valves which are operated by a computer which transmits an on-off digital signal to each three-way valve. According to the digital signal transmitted by the computer, each three-way valve will either allow said pneumatic signal to be transmitted to a respective valve associated therewith for causing the valve to open, or prevent the pneumatic signal from affecting the respective valve thus maintaining it closed.

摘要： An adsorption process for purifying or fractionating a gaseous feed mixture comprises an adsorption phase, at least one expansion phase, a purging phase and at least one pressure build-up phase. The expansion phase(s) and the purging phase produce residual process gas fractions. The sum total of volume, and/or mass streams of the residual process gas fractions comprises a residual gas stream which is maintained chronologically substantially constant by controlling the volume and/or gas streams of the gas entering the purging phase and maintaining the gas leaving the expansion phase(s) at a substantially constant value, dependent on the desired mass and/or volume quantity of the residual gas stream. The length of the purging phase and of the expansion phase(s) is adjusted accordingly so that the relationship of the length of time of the purging phase to the length of time of the expansion phase(s) is substantially the same as the relationship of the volume and/or mass of the gas fractions obtained during the purging to those obtained during the expansion phase(s), respectively. The control of the purging and of the expansion phase(s) can also be varied in response to a flow rate of a feed gas entering the process.

摘要： Disclosed is a method of sequentially separating and recovering one or more NGLs (129, 229) from a natural gas feedstream (3). Specifically, a raw natural gas feedstream (3) is passed through two or more NGLs separation unit (100, 200) wherein each separation unit removes one or more NGLs from the natural gas feedstream to provide a methane-rich natural gas supply (205). Each separation unit employs an adsorption media and has an adsorption step and a media regeneration step wherein the regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process. One embodiment of this method provides for the use of a different regenerable adsorbent media in each separation unit.

摘要： In pressure swing adsorption processing including higher pressure adsorption, cocurrent depressurization to intermediate pressure, countercurrent depressurization and/or lower pressure purge and repressurization, a cocurrent purge step is employed at adsorption pressure prior to cocurrent depressurization. Methane or natural gas is advantageously employed as the cocurrent purge gas. The cocurrent purge step reduces the storage of product gas, such as hydrogen, in the bed, enhances product recovery and correspondingly reduces the amount of desired product gas discharged with the waste gas discharged the countercurrent depressurization and/or purge steps used for bed regeneration. The value of the waste gas as a fuel is likewise enhanced by the presence of said methane or natural gas therein.

摘要： A PSA system that purifies a feed gas, such as a reformate gas in fuel cell system. The PSA system includes a series of vessels housing an adsorbent or combination of adsorbents that adsorb carbon monoxide, carbon dioxide, nitrogen, water and methane in the reformate gas. The adsorbent vessels are connected to each other and a feed manifold, a product manifold and an exhaust manifold through suitable conduits, where the gas flows are controlled by a product rotating valve and feed rotating valve or a series of open/shut valves. A specialized PSA cycle controls the valves so that the vessels cycle through various stages of equalization, blow-down, purge, pressurization and production to purify the feed gas.

摘要： The number of beds on the adsorption step of a pressure swing adsorption cycle is varied cyclically throughout the cycle. As a result, the final bed repressurization step is separated from the partial repressurization-pressure equalization step, thereby enhancing product recovery, without discontinuity in the flow of product effluent from the adsorption system or the use of an external repressurization storage tank.
