Abstract: A pressure swing adsorption (PSA) system using two or more valves for controlling the flow of gases entering or exiting a bed of adsorbents is disclosed, where the two or more valves are opened sequentially (i.e., in at least two actions separated by a delay in time). The sequential opening of the valves may increase the degree to which adsorbed species are purged from the bed, and also facilitates more rapid execution of certain time steps of the PSA cycle, thus increasing adsorbent productivity The sequential opening of the valves may also allow for verification of valve operation by measuring either the absolute value, the slope (derivative) or the rate of change of derivative of the pressure, either in the adsorbent bed, in the downstream manifold, or in a volume of gas held in a buffer vessel.

Abstract: An improved process for the production of olefins, and in particular for separation of olefins produced by a dehydrogenation process from paraffin feed stocks, is provided. A high pressure product splitter is used to separate olefins produced in a dehydrogenation plant from residual paraffin feed stocks. The use of a high pressure splitter to separate olefin products from paraffin feed stocks allows for recovery of a high purity olefin product with lower energy consumption compared to prior art processes. The process is particularly suited to separation of propylene from propane.

Abstract: A method and system for providing heat to a chemical conversion process is advantageously employed in the production of olefin by the catalytic dehydrogenation of a corresponding hydrocarbon. The catalytic dehydrogenation process employs diluent steam operating at a steam to oil ratio which can be 1.0 or below and relatively low steam superheater furnace temperature. The process and system are advantageously employed for the production of styrene by the catalytic dehydrogenation of ethylbenzene.
