DEVICE CONTAINING SIDE LIQUID INJECTORS FOR LIMITATION OF PROCESSES OF SOLID PRECIPITATE DEPOSITION IN EQUIPMENT WITH CONICAL BOTTOM Russian patent published in 2022 - IPC B01J19/24 C10G47/26 

FIELD: separation; distillation.

SUBSTANCE: invention relates to a device for downward flow of liquid hydrocarbons, containing solid particles at the bottom of equipment, having an upper cylindrical part with a diameter D1, a lower truncated-conical part with an angle of inclination α from 5° to 85° relatively to a vertical axis (z) of the specified upper cylindrical part, an outlet line with a diameter D2. It contains at least one injector for the injection of recirculating and/or make-up liquid to the truncated-conical part of equipment, at least one injector for the injection of recirculating and/or make-up liquid to the cylindrical part of equipment. In this case, the specified injector or injectors in the specified truncated-conical part are inclined relatively to a wall of the lower truncated-conical part at an angle β1 in a vertical plane (xz) and at an angle β2 in a horizontal plane (xy). The specified injector or injectors in the specified cylindrical part are inclined relatively to a wall of the upper cylindrical part at an angle θ1 in a vertical plane (xz) and at an angle θ2 in a horizontal plane (xy). Angles β1 and θ1 are from 5° to 175°, and angles β2 and θ2 are from 90° to 270°.

EFFECT: providing the reduction in the precipitate deposition or unstable or insoluble molecules in equipment for the separation and distillation, preferably with a conical bottom, with reduction in stagnation zones due to the return of liquid hydrocarbons or the injection of external make-up liquid simultaneously inside the truncated-conical part and inside the cylindrical part of equipment.
