Present invention offer is a kind of to prepare the production technology of sulfur it is therefore an objective to avoid coke oven after impact purification with claus oven
The h of coal gas2S content's index.
To achieve these goals, the technical scheme that the present invention takes is: prepares the production work of sulfur with claus oven
Skill, including step:
S1, by benzene hydrogenation stabilizer effusion dispersing gas deliver in sour steam pipe road；
S2, will deliver in sour steam pipe road through the sour gas that coke oven gas purification system produces, sour gas dispersing gas mix
Close and form gaseous mixture；
S3, the gaseous mixture in sour steam pipe road is delivered in claus oven, prepare sulfur.
Hydrogen sulfide is contained in described dispersing gas and described sour gas.
In described step s1, the temperature of dispersing gas is controlled to be 49-53 DEG C, the pressure controlling dispersing gas is 0.4-0.7mpa.
Described benzene hydrogenation stabilizer is passed through the first pipeline and is connected with described acid steam pipe road, and the first pipeline is provided with the first valve
Door.
Described benzene hydrogenation stabilizer is connected with described coking coal cleaning system by second pipe, and second pipe is provided with second
Valve.
In described step s2, the process producing sour gas includes step:
S21, gas-liquid separation: coke-stove gas is delivered in gas-liquid separator, isolates the tar in coke-stove gas and ammonia；
S2, cooling: coke-stove gas is delivered in primary cooler and is cooled down；
S3, conveying；
S4, desulfurization, wash ammonia, wash benzene: absorb and purifying coke oven gas in hydrogen sulfide, ammonia and benezene material；
S5, deacidification or regeneration: absorb and the hydrogen sulfide in purifying coke oven gas cleaning mixture, ammonia and Blausure (German), form acid
Property gas.
The present invention prepares the production technology of sulfur with claus oven, can reduce the h in coke-stove gas before desulfurization2S content,
Thus reducing the h in coke-stove gas after purification2S content, it is to avoid the h of coke-stove gas after impact purification2S content's index, reduces coke oven
The desulphurization cost of coal gas.
Brief description
This specification includes the following drawings, and shown content is respectively:
Fig. 1 is the flow chart of production technology of the present invention；
In figure is labeled as: 1, sour steam pipe road；2nd, the first pipeline；3rd, second pipe；4th, the first valve；5th, the second valve.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is made further details of
Illustrate it is therefore an objective to help those skilled in the art that the inventive concept of the present invention, technical scheme are had more completely, accurately and deeply
Understanding, and contribute to its enforcement.
The invention provides a kind of production technology preparing sulfur with claus oven, comprise the following steps that
S1, by benzene hydrogenation stabilizer effusion dispersing gas deliver in sour steam pipe road；
S2, will deliver in sour steam pipe road through the sour gas that coke oven gas purification system produces, sour gas dispersing gas mix
Close and form gaseous mixture；
S3, the gaseous mixture in sour steam pipe road is delivered in claus oven, prepare sulfur.
In step s1, benzene hydrogenation stabilizer is for hydrogenated oil is carried out in benzene hydrogenation process with the distillation of distillation under pressure dress
Put, be for removing the materials such as the hydrogen sulfide in hydrogenated oil and ammonia.As shown in figure 1, benzene hydrogenation stabilizer passes through the first pipeline
It is connected with sour steam pipe road, the first pipeline is provided with the first valve.Benzene hydrogenation stabilizer passes through second pipe and coking coal cleaning system
Connect, second pipe is provided with the second valve.When benzene hydrogenation process is carried out, dispersing gas can be produced in benzene hydrogenation stabilizer, diffuse
Hydrogen sulfide is contained, in benzene hydrogenation stabilizer, the dispersing gas of effusion can be sent to acid respectively through the first pipeline and second pipe in gas
In steam pipe road and coking coal cleaning system.During producing sulfur, the first valve is in normally open, and the second valve is in often
