INJECTION DEVICE, IN PARTICULAR FOR INJECTING A HYDROCARBON FEEDSTOCK INTO A REFINING UNIT Russian patent published in 2019 - IPC B01J8/24 B05B7/04 

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to an injection device, in particular to a device for injecting a hydrocarbon feedstock into a refining unit, and also to a reactor for processing a hydrocarbon feedstock, including such a device, and to a process for catalytic cracking of a hydrocarbon feedstock in a reactor. Injection device comprises a body comprising walls defining a recess extending axially, open in the direction of the gas inlet opening at one end and in the direction of the outlet opening of the atomized liquid at the other end, and a liquid inlet opening being provided laterally in the walls, inner walls of the body define a constriction whose neck is downstream of the gas outlet opening, and a gas injection assembly defining a passage for circulating gas between the gas inlet opening and a gas outlet opening located within the recess and forming, using the inner walls of the body, the space for circulation of liquid from the liquid inlet opening to the constriction neck, wherein the injection device is arranged so that the gas flow at the outlet opening covers a wall portion in close proximity to the constriction neck.

EFFECT: invention provides the simplified small pressure drop and high quality of atomization.
