SEPARATION SYSTEM OF ELEVATOR REACTOR Russian patent published in 2021 - IPC E21B43/34 B01D45/06 B01D45/08 B01J8/00 B01J8/18 C10G11/18 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to devices and methods for separating a gaseous mixture from a particle stream. A device contains reaction and separation tanks. The reaction tank contains the area of placement of a steaming layer located below and the area of placement of the secondary separator located above. The separation tank contains alternating separation and collecting chambers distributed in the axial direction around a central elevator reactor near an outlet of the central elevator reactor. Each separation chamber contains two vertical sidewalls, which also contain a wall of an adjacent collecting chamber, an inlet of the separation chamber, a deflector of the separation chamber. At least one of vertical sidewalls of each chamber contains a side outlet. Each collecting chamber contains an outer wall of the collecting chamber, which contains an inlet window of steam gas, a floor of the collecting chamber, which, together with the outer wall of the collecting chamber, the specified vertical sidewalls and the central elevator reactor, forms the collecting chamber, and at least one pipeline of the collecting chamber. Each separation chamber also contains an outer wall of the separation chamber, which passes from the inlet of the separation chamber in the direction of the area of placement of the steaming layer located below and, together with vertical sidewalls and the central elevator reactor, forms an outlet of the separation chamber located in the lower area of the separation chamber and communicating with the general area of a catalyst outlet located toroidally around the central elevator reactor and containing a wall of the general area of the catalyst outlet passing in the direction of the area of placement of the steaming layer located below from the outer wall of the separation chamber near the outlet of the separation chamber and from the outer wall of the collecting chamber near the floor of the collecting chamber and in a continuous circumferential direction around the central elevator reactor to direct solid particles to the area of placement of the steaming layer located below. The reaction tank also contains at least one secondary separator containing at least one exhaust gas pipeline communicating with a gas collector for the release of cracking gases. The gas collector contains an outlet and at least one downpipe with an outlet that passes inside the area of placement of the steaming layer located below to return separated solid particles to the area of placement of the steaming layer located below in the reaction tank.

EFFECT: device provides increased efficiency of gas and solid separation, maximizes the localization of hydrocarbons, minimizes the time of their presence in the separation system, and thus minimizes undesirable cracking reactions at the end of the process.
