Abstract: Processes for upgrading a hydrocarbon for a predetermined period of time. The process can include determining an amount of one or more contaminant-containing compositions that will be present in a pyrolysis effluent based, at least in part, on a composition of a hydrocarbon feed to be steam cracked, a temperature the hydrocarbon feed will be heated at during steam cracking, a residence time the hydrocarbon feed will be heated at the temperature during steam cracking, or a combination thereof. In some examples, the process can also include taking one or more steps to allow the hydrocarbon feed to be steam cracked for at least as long as a predetermined period of time, controlling process conditions within one or more separation stages to favor certain product compositions, introducing a predetermined amount of one or more agents into various locations of the process, or any combination thereof.

Abstract: Processes and systems for steam cracking hydrocarbons. Liquid water can be combined with a preheated hydrocarbon feed to produce a mixture, which can be heated to produce a heated mixture. At least a portion of the heated mixture can be steam cracked to produce an effluent. A process gas, a steam cracker naphtha, a condensed process water, and one or more heavy steam cracker products can be separated from the effluent. The condensed process water can include entrained hydrocarbons and at least a portion of the entrained hydrocarbons can be separated therefrom to produce a purified process water. At least a portion of the purified process water can be heated to produce dilution steam. The liquid water combined with the preheated hydrocarbon feed can include a portion of the condensed process water, a portion of the purified process water, condensed dilution steam, or a mixture thereof.

Abstract: 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.

Abstract: Disclosed are processes for converting an alkyne to an olefin comprising feeding a molecular-oxygen-containing gas stream into a converting zone of an alkyne converter along with an alkyn-containing feed mixture comprising hydrocarbons and molecular hydrogen to contact the converting catalyst. The converting catalyst can be regenerated online as a result.

Abstract: Processes are provided for removing contaminants from a refinery gas. Such process can include recovering a process gas comprising ethylene and propylene from a steam cracker effluent recovered from a stream cracker in a steam cracker facility. A refinery gas can be recovered from a refinery facility. The process gas can be compressed in a plurality of compressor stages. A pressure of the refinery gas can be determined. A compressor stage in the plurality of compressor stages can be selected for introducing the refinery gas using the determined pressure of the refinery gas. The refinery gas can be introduced into the selected compressor stage to produce a combined gas that can include the process gas and the refinery gas. At least a portion of one or more impurities can be removed from the combined gas in the steam cracker facility to produce an upgraded combined gas.

Abstract: In a process for converting methane to aromatic hydrocarbons, a feed containing methane and a particulate catalytic material are supplied to a reaction zone operating under reaction conditions effective to convert at least a portion of the methane to aromatic hydrocarbons and to deposit carbonaceous material on the particulate catalytic material causing catalyst deactivation. At least a portion of the deactivated particulate catalytic material is removed from the reaction zone and is heated to a temperature of about 700° C. to about 1200° C. by direct and/or indirect contact with combustion gases produced by combustion of a supplemental fuel. The heated particulate catalytic material is then regenerated with a hydrogen-containing gas under conditions effective to convert at least a portion of the carbonaceous material thereon to methane and the regenerated catalytic particulate material is recycled back to the reaction zone.
