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.

摘要: A system for refining crude oil to minimize emissions of toxic compounds in the atmosphere during refining. The crude oil is treated with viscosity-reductant additives, reducing viscosity by up to 50% and increasing API gravity by more than 2 points. The method of spray-cracking and vacuum-flashing of crude oil, the system separates light and heavy end chains within the reactor. The vapor is condensed into designer fuels using a multi-stage horizontal reverse condensate-condenser or closed-loop distillation tower. Process heater directs flue gases through high-salinity fluids, such as a brine-processing device to capture, sequester, or mineralize the CO2, CO, NOx, and other contaminants from the flue gases. This results in a significant reduction in emissions, a further reduction to near-zero emissions (>95-98%) is achieved by the combination of (1) the closed loop processes, tank blanketing and capturing, sequestering and mineralizing emitted flue gases from the heater combustion-exhaust.

摘要: A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

摘要: A method for thermal processing and catalytic cracking of a biomass to effect distillate oil recovery can include, particle size reduction. slurrying the biomass with a carrier fluid to create a reaction mixture, slurrying a catalyst with a carrier fluid to create a catalyst slurry, heating the reaction mixture and/or the catalyst slurry, and depolymerizing the reaction mixture with the catalyst. The reaction mixture can undergo distillation and fractionation to produce distillate fractions that include naphtha, kerosene, and diesel. In some embodiments, thermal processing and catalytic cracking includes vaporization of the biomass followed by distillation and fractionation. In some embodiments, a resulting distillate can be used as a carrier fluid. In some embodiments, the method can include desulfurization, dehydration, and/or decontamination.

摘要: A method of recovery of rich gas where the rich gas is a hydrocarbon gas comprising less than 50 mole % methane is disclosed. The method comprises the steps of gathering the low pressure gas, compressing the gathered gas, cooling the compressed gas in a condenser so that a portion of the compressed gas condenses to form a liquefied gas and liquefied gas vapour in the condenser, and discharging the liquefied gas and liquefied gas vapour from the condenser, in which the cooling of the compressed gas is performed using at least one heat exchanger (40).

摘要: A method for separating a hydrocarbon mixture, which is obtained at least in part by steam cracking and which contains at least hydrocarbons having one, two and three carbon atoms, including ethane and ethylene, a first fraction initially being obtained from the hydrocarbon mixture by separating off other components at least in part, said fraction containing the predominant part of the hydrocarbons having two or more carbon atoms previously contained in the hydrocarbon mixture or the predominant part of the hydrocarbons having two or fewer carbon atoms previously contained in the hydrocarbon mixture, further fractions subsequently being obtained from the first fraction. A fraction containing ethane is separated off in an amount which reduces the ethane content in the first fraction to less than 25%, the fraction containing ethane being low in or free from other hydrocarbons having two carbon atoms.
