摘要:
The present disclosure relates to a single shell open interstage reactor (“SSOI”). The SSOI comprises a first reaction stage, an interstage heat exchanger, an open interstage region, and a second reaction stage. The SSOI may be configured for upflow or downflow operation. Further, the open interstage region of the SSOI may comprise a supplemental oxidant feed. When the open interstage region comprises a supplemental oxidant feed, the SSOI may further comprise a supplemental oxidant mixing assembly. Processes for producing acrylic acid through the oxidation of propylene are also disclosed.

The invention relates to a method for producing a flow containing at least one alkene derivative, including the following steps: a step a) of reacting a flow containing one or more alkenes and one or more alkanes—the ratio of said alkanes to said alkenes being at least 1 by volume—with a flow containing mainly oxygen, in order to obtain at least one converted flow containing at least said alkene derivative; a step b) of separating the converted flow produced in step a) into at least said flow containing at least said alkene derivative and a residual flow containing mainly one or more hydrocarbons and one or more inert compounds; and a step c) of separating all or a portion of said residual flow by means of permeation into at least one first flow containing mainly one or more inert compounds and a second flow containing mainly one or more hydrocarbons.

The invention relates to a method for purifying a specific gas stream containing one or more components to be recovered, one or more impurities to be eliminated and one or more poisons, for a unit for separation by means of permeation, including the following steps: a) in a unit for separation by means of absorption, separate from said unit for separation by means of permeation, the specific gas stream is placed in contact with one or more liquid solvents suitable and intended for selectively absorbing said poisons in order to obtain at least one first gas stream depleted of said poisons and a second liquid stream; and b) said first gas stream produced in step a) is separated in said unit for separation by means of permeation, at a specific absolute pressure P, into at least one third gas stream depleted of impurities and a fourth stream; the separation performed in step a) being carried out at an absolute pressure of between 50% and 200% of said specific absolute pressure P.
摘要:
The invention relates to a process of the selective oxidation of carbon monoxide to carbon dioxide present in a gas mixture comprising at least one hydrocarbon or a hydrocarbon derivative, and to its integration into a process for producing hydrocarbon derivatives. The process according to the invention comprises a step that consists in bringing said gas mixture into contact with a solid catalyst capable of oxidizing carbon monoxide to carbon dioxide at a chosen temperature, characterized on that said step is carried out in a fluidized bed.
