摘要： The present invention is a method of minimizing the emissions of carbon dioxide from a reformer furnace flue gas to the high pressure syngas exit water gas shift reaction unit. Including heating a first gas mixture by indirect heat exchange with one or more of an SMR furnace flue gas or an SMR furnace syngas, further heating the pre-reformed mixture in a primary reformer, thereby generating a second gas mixture comprising hydrogen, carbon monoxide, carbon dioxide, and a flue gas. Introducing the gas mixture into a standard H2 PSA unit, wherein the gas is separated into a hydrogen enriched stream and a PSA tail gas stream, and introducing PSA feed or tail gas stream into a carbon dioxide removal system, wherein the flue gas is separated into a residual flue gas stream and a carbon dioxide enriched stream.

摘要： This present invention provides a method to more efficiently recover hydrogen and carbon dioxide, preferably at least 50%, even more preferably at least 75%, and most preferably at least 90% of the carbon dioxide. The present invention further provides the design for capture of at least 80%, carbon dioxide from syngas that allows for the simultaneous production of medium to high amounts of hydrogen in the syngas as a part of the production of hydrogen in a hydrogen generation plant. 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 units 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 two hydrogen membrane separation units are utilized.

摘要： A hydrocarbon feedstock is simultaneously distilled into two or more fractions while trace concentrations of contaminants in the feedstock are absorbed onto a sorbent packing material during distillation operation. The sorbent packings contain active metal components supported on porous refractory oxides. Such sorbent packings provide surfaces for mass transfer in the distillation process and concurrently absorb contaminants. Product boiling fractions from the absorption-distillation process are further processed over contaminant-sensitive catalysts such as reforming or isomerization catalyst.

摘要： The present invention provides a process for recovering hydrogen and carbon dioxide from a process stream (1) of a process unit (0) wherein the process stream (1) contains at least carbon dioxide, hydrogen and methane. In the process, the process stream (1) is optionally compressing in a first compressor (2) before being cooled in a heat exchanger (3) to a temperature equal to or less than −10° C. Next, the cooled process stream (1) is separated and purified in a carbon dioxide separation unit (4) to produce a carbon dioxide rich liquid stream (6) and a carbon dioxide lean non-condensable stream (5) with the carbon dioxide rich liquid stream (6) being withdrawn as a carbon dioxide product for further use. The carbon dioxide lean non-condensable stream (5) is then withdrawn from the carbon dioxide separation unit (4) and passed through a hydrogen selective membrane separation unit (7) to form a hydrogen rich permeate stream (8) with the remaining components in the carbon dioxide lean non-condensable stream (5) forming a hydrogen lean residue stream (9). The hydrogen lean residue stream (9) is passed through a carbon dioxide selective membrane separation unit (10) to form a carbon dioxide enriched permeate stream (11) with the remaining components in the hydrogen lean residue stream (9) forming a carbon dioxide depleted residue stream (12). The hydrogen rich permeate stream (8) is optionally compressed in a second compressor (13) and recycled for use as a supplemental feed stream in the process unit (0) or in other processes. The carbon dioxide enriched permeate stream (11) is recycled to the process stream (1) prior to the compressor (2) or within the compressor (2) between stages of compression, or to the carbon dioxide separation unit (4) while the carbon dioxide depleted residue stream (12) is withdrawn for further use. The present invention further relates to the use of this process within a hydrogen generation plant to increase recovery of hydrogen and capture equal to or greater than 90% of the carbon dioxide in the syngas stream.
