摘要： A process for removing contaminants from an off-gas stream generated by the methylation of toluene and/or benzene by methanol to produce para-xylene. The treated off-gas stream, which contains C4− hydrocarbons, may be further processed in an olefins plant/process to yield valuable light alkanes and olefins.

摘要： An H2-rich fuel gas production plant comprising a syngas production unit can be advantageously integrated with an olefins production plant comprising a steam cracker in at least one of the following: (i) fuel gas supply and consumption; (ii) feed supply and consumption; and (iii) steam supply and consumption, to achieve considerable savings in capital and operational costs, enhanced energy efficiency, and reduced CO2 emissions, compared to operating the plants separately.

摘要： An exhaust steam stream having an absolute pressure from 200 kPa to 1,050 kPa and shaft power are produced from an extraction turbine and/or a back-pressure turbine. The exhaust steam stream can be supplied to an amine regenerator of an amine CO2 separation process. The shaft power can be utilized to drive equipment in a hydrocarbon processing plant such as an olefins production plant.

摘要： An H2-rich fuel gas stream can be advantageously produced by reforming a hydrocarbon/steam mixture in to produce a reformed stream, followed by cooling the reformed stream in a waste-heat recovery unit to produce a high-pressure steam stream, shifting the cooled reformed stream a first shifted stream, cooling the first shifted stream, shifting the cooled first shifted stream to produce a second shifted stream, cooling the second shifted stream, abating water from the cooled second shifted stream to obtain a crude gas mixture stream comprising H2 and CO2, and recovering a CO2 stream from the crude gas mixture stream. The H2-rich stream can be advantageously combusted to provide thermal energy needed for residential, office, and/or industrial applications including in the H2-rich fuel gas production process. The H2-rich fuel gas production process can be advantageously integrated with an olefins production plant comprising a steam cracker.

摘要： Processes and systems for upgrading a hydrocarbon. In some embodiments, the process for upgrading a hydrocarbon, can include contacting a gas that can include one or more C1-C4 hydrocarbons and carbonyl sulfide with a sorbent under conditions sufficient to cause at least a portion of the carbonyl sulfide to sorb onto the sorbent to produce a treated gas lean in carbonyl sulfide and a sorbent rich in carbonyl sulfide. The process can also include contacting the sorbent rich in carbonyl sulfide with a regenerating gas that can include molecular hydrogen, one or more C1-C4 hydrocarbons, or a mixture thereof to produce a regenerated sorbent and a desorb effluent that can include a sulfur-based contaminant. The process can also include introducing at least a portion of the desorb effluent into a pyrolysis zone of a steam cracker and recovering a steam cracker effluent from the pyrolysis zone.
