INSTALLATION FOR PRODUCING TECHNICAL (THERMAL) CARBON FROM GASEOUS HYDROCARBON RAW MATERIAL Russian patent published in 2018 - IPC C09C1/54 

FIELD: oil industry.

SUBSTANCE: invention relates to oil and gas industry and can be used at mining enterprises, preparing for transport and processing of hydrocarbons. Installation for the production of technical (thermal) carbon from a gaseous hydrocarbon feedstock contains continuous reactor 1 with a separate outlet of flue gases and a gas / gas mixture, evaporative cooling device 2 of the soot gas mixture, gas / gas mixture separation filter 3, carbon black collecting and processing device 4, communicated with fan 10 of the pneumatic transport system. At the outlet of the flue gases from reactor 1 two-stage ejector scrubber 5 is located. At the exit of the dust-free pyrogas, ejector scrubber 6 from filter 3 is located. At the inlet of air to reactor 1 are located air heater 7 and air blower 8. Gas blower 9 is connected to the gas outlet of scrubber 6. Steam boiler-heat exchanger 11 is connected to the outlet of flue gases from reactor 1. Flue gas output from steam recovery boiler 11 is connected to two-stage ejector scrubber 5 located in the lower part of chimney 12. Input of the superheated steam of electric generator 13 with steam drive 14 through flow controller 15 is connected to the steam outlet of waste heat boiler 11. Output of the exhaust steam from steam drive 14 is connected to parallel heat exchanger-condenser 16 in parallel to the steam and to air-cooling condenser 17, condensate water outlets from which are connected to the inputs of parallel connected feed pump 18, steam ejector pump 19 and circulation pump 20, on the input of which also filtered water condensate is fed from ejector scrubber 6. Outputs of the feed pump 18 and steam jet pump 19 are connected to the feed water inlet of waste heat boiler 11. Output of circulation pump 20 is connected to the water condensate inlet from ejector scrubber 6 to air heater 7, outlet of the water condensate from which is connected to the nozzles of evaporative cooling device 2 of the soot gas mixture and ejector scrubber 6. Outlet of the water condensate of deaerator 21, equipped with submersible pump 22, is connected to water condensate filter 23, output of which is connected to the inlet of an air cooler of condensate 24, output of which is connected to a collector of cooled water condensate 25, to which the inputs of feed pump 18, steam injector pump 19, circulation pump 20 and network pump 26, and second stage nozzle 28 of two-stage ejector scrubber 5 are connected via condensate flow controller 27. Branch 29 of the water condensate drain from the second stage is connected to the water condensate inlet of deaerator 21. Service water line 31 is connected to first stage nozzle 30 of the two-stage ejector scrubber 5. Outlet of the flue gases from reactor 1 is connected to the inlet of parallel connected main 32 and bypass 33 smoke flaps, flue gas outlets from which are connected respectively to the input of waste heat boiler 11 and bypass inlet branch pipe 34 of chimney 12, which is also equipped with a branch pipe for the selection of cooled flue gases 35, located along the height of the chimney between the second stage of ejector scrubber 5 and bypass inlet branch pipe 34. Bleed nozzle 35 is connected through gate 36 to the inlet of fan 10 of the pneumatic conveying system. Energy efficiency of the installation is increased, the cost of hydrocarbons, fuel and electricity in the production of carbon black is reduced.

EFFECT: energy autonomy of the installation allows it to be used at field sites remote from energy and water supply systems.
