SYSTEM FOR DESULFURIZATION WITH THE GEAR OF TRANSFER OF THE SORBENT Russian patent published in 2007 - IPC C10G29/04 B01J8/18 B01J38/04 

FIELD: chemical industry; petrochemical industry; other industries; methods and the devices for removal of the sulfur from the streams of the fluid medium containing the hydrocarbons.

SUBSTANCE: the invention is pertaining to the method and the installation for removal of the sulfur from the streams of the fluid medium containing the hydrocarbons. The method of desulfurization includes the following stages: a) contacting of the hydrocarbon-containing stream of the fluid medium with the solid particles of the sorbent in the reactor, (b) the increase of the pressure in the reactor airlock storage bin up to the filling pressure, (c) transportation of the sulfur filled particles of the sorbent from the reactor into the being under pressure airlock storage bin of the reactor, (d) reduction of the pressure in the filled airlock storage bin to the pressure of release, (e) transportation of the sulfur filled particles of the sorbent from the filled and being under low pressure airlock storage bin of the reactor into the recuperator and (f) contacting of the sorbent particles with the oxygen-bearing recuperation stream. The installation of desulfurization contains the reactor with the fluidized layer of the sorbent, the receiver of the reactor for reception of the sulfur filled particles of the sorbent, the airlock storage bin of the reactor, the receiver of the recuperator for reception of the recuperated particles of the sorbent, the airlock storage bin of the recuperator for reception of the recuperated particles of the sorbent and the installation of the recuperation. The control system of transmission of the finely dispersed solid particles from the first container into the second container contains the airlock storage bin disposed streamwise between the first and second containers, the valve for filling up by the particles disposed streamwise between the first container and the airlock storage bin, the valve for release of the particles disposed streamwise between the airlock storage bin and the second container, the first gaseous line hydraulically linked to the airlock storage bin and including the first gaseous valve for control over the flow of the first gas through the first gaseous line, the line of a blowing through hydraulically linked to the airlock storage bin and including the outlet valve for the flow control of the fluid medium through the blowing line, the pressure control detector for determination of the pressure in the airlock storage bin, and the electronic control device intended for connection with the valve for filling up by the particles, the valve of the release of the particles, the first gaseous valve, the outlet valve and the pressure control device. The electronic control device is programmed so that to execute the following serial stages: (a) to open the first gaseous valve; (b) to close the first gaseous gate in reply to the first reading of the pressure control device; (c) to open the valve for filling up with the particles; (d) to close the valve filling up with the particles; (e) to open the release valve; (f) to close the release valve in reply to the second reading of the pressure of the pressure control device; (g) to open the valve o the particles release; and (h) to close the valve of the particles release The invention allows to increase efficiency of the hydrocarbons desulfurization.

EFFECT: the invention allows to increase efficiency of the hydrocarbons desulfurization.
