摘要： A method of separating hydrocarbons containing three or more carbon atoms from an off-gas stream is provided. This method includes separating a light ends stream from a fractionator, thereby producing a stream rich in hydrocarbons containing three or more carbon atoms, and a stream lean in hydrocarbons containing three or more carbon atoms, separating the stream lean in hydrocarbons containing three or more carbon atoms in a membrane unit, thereby producing a permeate stream enriched in hydrocarbons containing three or more carbon atoms and a retentate stream, and separating the stream rich in hydrocarbons containing three or more carbon atoms in one or more separation columns, thereby producing one or more streams selected from the group consisting of a propylene stream, a propane stream, a butane stream, a light cat naptha stream, and a heavy cat naptha stream.

摘要： The present invention provides a process for recovering hydrogen and carbon dioxide from a process stream utilizing a carbon dioxide separation unit and two membrane separation units. The present invention further provides a process within a hydrogen generation plant to increase recovery of hydrogen and capture equal to or greater than 80% of the carbon dioxide in the syngas stream. By using the process of the present invention, especially in terms of a hydrogen generation plant, it is possible to increase recovery of hydrogen and capture of the carbon dioxide in the syngas stream by balancing the recycle of the hydrogen rich permeate from the hydrogen membrane separation unit to the process unit and/or the water gas shift as capacity allows when a carbon dioxide separation unit, a carbon dioxide membrane separation unit and a hydrogen membrane separation unit are utilized.

摘要： An apparatus and method for drying a moist gas is provided. The apparatus includes a revolving desiccant rotor with at least an adsorption sector and a regeneration chamber; the regeneration chamber comprising at least a first dry gas sector, a hot regeneration sector, and a second dry gas sector, and optionally a cold regeneration sector. The method includes at least an adsorption sector and a regeneration chamber; the regeneration chamber comprising at least a first dry gas sector, a hot regeneration sector, and a second dry gas sector, and optionally a cold regeneration sector. This method includes the steps of; contacting a moist gas stream (401) with the desiccant in the adsorption sector, thereby producing a dry gas stream (402); contacting a first dry gas stream (407) with the desiccant in the first dry gas sector, thereby producing a first wet gas stream (408); contacting a hot partially wet gas stream (403) with the desiccant in the hot regeneration sector, thereby producing a warm wet gas stream (404); contacting a dry regeneration gas stream with the desiccant in the second dry gas sector, thereby producing a wet regeneration gas stream, and contacting a regeneration purge gas stream (405) with the desiccant in the cold regeneration sector, thereby producing a warm purge gas stream (406).

摘要： The present invention relates to a method for the combined production of hydrogen and carbon dioxide from a hydrocarbon mixture, in which the hydrocarbon mixture is reformed to produce a syngas which is cooled, then enriched with H 2 and CO 2 , optionally dried, and treated in a PSA hydrogen purification unit to produce hydrogen, the PSA offgas being treated to capture the CO 2 and to supply an offgas. This offgas is again treated to supply a stream enriched with H 2 and CO 2 which is returned to the PSA, where it constitutes a second feed distinct from the main feed.
