摘要： Process of treating a net gas stream is disclosed. The process includes sending the net gas stream to a compressor to produce a compressed gas stream. The compressed gas stream is then sent to a pressure swing adsorption unit to produce a hydrogen product stream and a tail gas stream. Tail gas stream from the pressure swing adsorption unit is sent to a first membrane unit to produce a first permeate stream and a first non-permeate stream. Portion of the tail gas stream is sent to a second membrane unit to produce a second permeate stream and a second non-permeate stream.

摘要： Processes for the production of a gasoline blend. A C7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C7 saturated hydrocarbons are convert to C7 olefins. The C7 olefins have a higher octane number than the C7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C7 olefins can be blended in a gasoline pool. C5 and C6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C7 components.

摘要： The process produces a diesel stream from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The recycle gas is recycled to the hydrotreating reactor without removing hydrogen sulfide, which is needed in the biorenewable feed to keep the hydrotreating catalyst active. A purification unit can be utilized on a purge gas stream to purify the gas and improve hydrogen concentration in the recycle gas when added to the recycle gas.

摘要： A system that is used for the treatment of a net gas stream is disclosed. The system includes a compressor to produce a compressed gas stream from a net gas stream. The compressor is connected to a pressure swing adsorption unit where the net gas stream is separated to produce a hydrogen product stream and a tail gas stream. Tail gas stream from the pressure swing adsorption unit is sent to a first membrane unit to produce a first permeate stream and a first non-permeate stream. A portion of the tail gas stream is sent to a second membrane unit to produce a second permeate stream and a second non-permeate stream.

摘要： Processes for co-processing a naphtha stream with a light cycle oil stream are disclosed. The processes include hydrocracking the light cycle oil stream under hydrocracking conditions to provide a hydrocracked effluent stream. A naphtha stream is hydrotreated under hydrotreating conditions to provide a hydrotreated effluent stream. The hydrocracked effluent stream and the hydrotreated effluent stream may be passed to a stripping column to recover a stripping bottom stream. The stripping bottom stream may be passed to a main fractionation column to recover an intermediate naphtha stream.

摘要： A new process and apparatus for ethanol dehydration combines a fired heater with a dehydration reactor in a single vessel. The reactor provides catalyst tubes in a firebox. The catalyst may be added to and withdrawn from the catalyst tubes. The apparatus reduces equipment account substantially while holding the reaction to isothermal conditions.

摘要： A process and apparatus for hydrocracking a distillate stream and provides for separation into product cuts without a separate debutanizer column, a naphtha splitter column or a sponge absorber column. The product cuts include a C3-C5 LPG stream and a heavy naphtha stream which can be useful as a reforming feed stream. Additionally, as few as two heaters that rely on external utilities may be required for reboiling fractionator column bottoms.

摘要： A process is disclosed for producing hydrogen for a hydrogen consuming process comprising obtaining a gas stream containing hydrogen from a steam reforming hydrogen plant, sending the gas stream to a pressure swing adsorption unit to be separated into a hydrogen stream and a fuel gas stream; purging the pressure swing adsorption unit with an external purge gas stream from a hydroprocessing unit off gas; treating the off gas with a thermal swing adsorption unit to remove water and other impurities prior to purging the pressure swing adsorption unit; and using a protective adsorbent layer in the pressure swing adsorption unit at the product-hydrogen end of the bed to adsorb impurities from the external purge gas.
