Embodiment 1

[0030] Embodiment 1, see accompanying drawing:

[0031] Sulfur recovery unit: acid gas from petrochemical enterprises or carbon disulfide units at 40°C, 0.15MPa, according to 2H 2 S+O 2 =2S+2H 2 O, 2H 2 S+3O 2 =2SO 2 +2H 2 O, 2H 2 S+SO 2 =2S+2H 2O Reaction equation gas distribution, sent to the Claus furnace 19, 19 behind the Claus furnace contains a waste heat boiler, the temperature of the Claus furnace is raised to 1100-1300 ° C, preferably 1200 ° C to react, the gasified sulfur and the mixture The gas product is cooled to 400-450°C after being heated by the waste heat boiler, 400°C is selected, and sent to the condenser 20, the temperature is cooled to 160-170°C, and 165°C is selected, and the liquid sulfur captured by the sulfur trap enters Liquid sulfur tank 30, process gas goes to heater 21, goes to converter 22 after heating, through condenser 23, the sulfur of catcher is sent into liquid sulfur tank 30, carried out four-stage cooling 20, 23, 26, 29, three-st...

Embodiment 2

[0034] Embodiment 2, see accompanying drawing:

[0035] Sulfur recovery unit: acid gas from petrochemical enterprises or carbon disulfide units at 40°C, 0.15MPa, according to 2H 2 S+O 2 =2S+2H 2 O, 2H 2 S+3O 2 =2SO 2 +2H 2 O, 2H 2 S+SO 2 =2S+2H 2 O Reaction equation gas distribution, send it to Claus furnace 19, heat up 1100-1300°C, choose 1300°C for reaction, the generated gasified sulfur and mixed gas products are cooled to 400-450°C by waste heat boiler, choose 430°C, send Enter the condenser 20, the temperature is cooled to 170-170 ° C, choose 170 ° C, the liquid sulfur captured by the sulfur trap enters the liquid sulfur tank 30, the unreacted gas goes to the heater 21, and after heating, it goes to the converter 22 , through the condenser 23, the sulfur of the catcher is sent to the liquid sulfur tank 30, and four-stage cooling 20, 23, 26, 29, 21, 24, 27, and three-stage conversion 22, 25, 28 are carried out by this method , the collected liquid sulfur enters t...

Abstract

The invention provides a novel process for simultaneous production of carbon disulfide, sulfur and insoluble sulfur. The carbon disulfide, the sulfur and the insoluble sulfur can be produced in the same combined device. According to the invention, a conventional sulfur recycling device in a petrochemical enterprise is designed to be able to produce sulfur by using desulfurized gas in the petrochemical enterprise and waste gas of a carbon disulfide device; liquid sulfur is simultaneously used as a raw material for production of sulfur, carbon disulfide and insoluble sulfur; carbon disulfide isproduced through a reaction of methane and ethane in the petrochemical enterprise and gasified sulfur of an insoluble sulfur device; the insoluble sulfur is extracted with self-produced carbon disulfide; and extracted waste liquid returns to the carbon disulfide device for recycling, so a pure carbon disulfide product is obtained. The combined production process provided by the invention is linkedtogether and has the advantages of simple process, short flow, less equipment and convenient operation.

Description

technical field [0001] The invention relates to a process for simultaneously producing three chemical products of carbon disulfide, sulfur and insoluble sulfur in one combined device, and belongs to the field of petrochemical industry. technical background [0002] Carbon disulfide is widely used and can be used as an intermediate of chemical raw materials, as well as a solvent and extractant, etc.; insoluble sulfur is mainly used in the manufacture of automobile tires, rubber synthetic products, carpets, rubber hoses, tapes, rubber shoes, etc.; sulfur is mainly used in rubber tires, Fireworks and firecrackers, chemical fertilizers, food industry, pesticides (for disinfection of flowers, plants, trees and fruit trees), daily chemical aids, industrial products, etc. At present, the production of these three products is mostly established in separate factories in different places, each with its own site, workshop, warehousing, transportation, public works, production equipment...
