    Abstract: The invention involves a process for treating a gas stream from a hydroprocessor that contains hydrogen, methane and C2+ hydrocarbons. In embodiments of the invention, the gas stream is sent through at least two pressure swing adsorption units to produce a high quality hydrogen stream, a fuel gas stream containing most of the methane and a tail gas stream that is sent to a steam cracker. Lean gas from a gas plant and other refinery off gases may also be processed together with the gas stream from the hydroprocessor.

    Abstract: Methods and apparatuses for processing hydrocarbon streams are provided. In an embodiment, a method for processing a hydrocarbon stream includes heating a feed stream in a convective bank. In the method, the feed stream is reacted in a first reaction zone to form a first effluent. The first effluent is heated in a first radiant cell that combusts fuel gas to heat the first effluent and forms a first exhaust gas. The method includes contacting the first exhaust gas with the convective bank to heat the feed stream.

    Abstract: A process for separation and treatment of a naphtha feedstock to increase overall octane in a gasoline blending pool by reducing or removing the normal pentane in the feedstock. The feedstock is passed into a divided wall column having an undivided top portion, an undivided bottom portion and a wall dividing a middle portion into two sections. The intermediate faction can include either all normal pentane, which can be utilized on other processes, or it can include a mixture of normal pentane and C6 hydrocarbons, which can be isomerized in an isomerization zone to increase the octane and then passed to a gasoline blending pool.

    Abstract: A process for recovering heat from the separation of hydrocarbons. The overhead vapor stream from a fractionation column is passed to a two stage heat pump compressor. The first stage of compression is used to reboil the fractionation column. The second stage is compressed and cooled passed to a separation zone. The liquid in the separation zone may be passed back to the fractionation column as secondary reflux, and/or recovered as liquid product. Heat may also be removed from the second stage. A suction drum on the first stage may be used to protect the heat pump compressor from any droplets in the overhead stream.

    Abstract: A process and apparatus integrate a deethanizer column with a cryogenic heat exchanger by reboiling the deethanizer column with a refrigerant stream and/or cooling a deethanizer overhead line in the cryogenic heat exchanger. A single stage separator and a single deethanizer column may be used to obtain high purity hydrogen in the net gas stream and an ethane rich off-gas stream, whereas conventionally a dual stage separator and two deethanizer columns were necessary for equivalent purity, respectively.

    Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H2-rich stream and a first liquid phase hydrocarbon stream. The H2-rich stream may be contacted with an adsorbent to form an H2-ultra rich stream and a gas stream. C3/C4 hydrocarbons are absorbed from the gas stream with the liquid phase hydrocarbon stream. The gas stream may be contacted with an H2/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H2-rich permeate stream and an H2 depleted non-permeate residue stream.
