Description
Technical field
This utility model belongs to alkyl plant technical field, relates to a kind of alkyl plant vapour system.
Background technology
Sulfuric acid alkylation is with iso-butane, butylene for raw material, and concentrated sulphuric acid (98%w) produces technical octane for catalyst.Technological process includes pretreatment of raw material, reaction compression, refining, the parts such as product fractional distillation, the tower reactor reboiler of deisobutanizer and the tower reactor reboiler of de-normal butane tower are the rich anies influential family using steam, at present, the tower reactor reboiler of deisobutanizer is connected with the jet chimney of 0.8MPA, the tower reactor reboiler of de-normal butane tower is connected with the jet chimney of 1.3MPA, in actual production process, produce isobutyltrimethylmethane. per ton and need the 1.3MPA steam of consumption 0.23 ton and the 0.8MPA steam of 0.74 ton, based on above-mentioned production process, the production cost of enterprise is of a relatively high, have a strong impact on the economic benefit of enterprise.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide the alkyl plant vapour system of a kind of production cost that can reduce isobutyltrimethylmethane..
Alkyl plant vapour system of the present utility model, including several deisobutanizers, several de-normal butane towers, for providing the first steam inlet of 0.8MPA steam and for providing the second steam inlet of 1.3MPA steam, described first steam inlet is communicated with the first jet chimney, the steam inlet of several deisobutanizers described is connected on the second jet chimney, described second jet chimney and the first jet chimney are by the first valve connection, described second steam inlet is communicated with the 3rd jet chimney, the steam inlet of several de-normal butane towers described is connected on the 4th jet chimney, described 4th jet chimney and the 3rd jet chimney are by the second valve connection, described second jet chimney and the 4th jet chimney are by the 5th jet chimney connection, described 5th jet chimney is provided with the 3rd valve.
Operation principle of the present utility model is: generally, the tower reactor reboiler of deisobutanizer needs to obtain the steam of 0.8MPA, the tower reactor reboiler of de-normal butane tower needs to obtain the steam of 1.3MPA, in this case, as long as opening the first valve and the second valve, and close the 3rd valve and can realize；When the tower reactor reboiler of the tower reactor reboiler of deisobutanizer and de-normal butane tower all needs the steam obtaining 1.3MPA, the second valve and the 3rd valve can be opened, and close the first valve and can realize；When the tower reactor reboiler of the tower reactor reboiler of deisobutanizer and de-normal butane tower all needs the steam obtaining 0.8MPA, the first valve and the 3rd valve can be opened, and close the second valve and can realize.By aforesaid operations, enterprise can according to needs of production, it is provided that the tower reactor reboiler of the steam of the different pressures tower reactor reboiler to deisobutanizer and de-normal butane tower.
nullThis utility model beneficial effect: this utility model is by the setting of the 3rd valve on the 5th jet chimney and the 5th jet chimney，When the tower reactor reboiler of deisobutanizer and the tower reactor reboiler of de-normal butane tower need the steam obtaining different pressures，Can when not changing original jet chimney，Realize the steam of different pressures is supplied to the tower reactor reboiler of deisobutanizer and the tower reactor reboiler of de-normal butane tower，There is practical advantage，And it is formerly used for the 4th jet chimney of conveying 1.3MPA steam，The steam of 0.8MPA can be carried easily，It is thus possible to the steam pressure in the 4th jet chimney is down to 0.8MPA and is supplied to the practicality of de-normal butane tower，Give with the steam being originally presented 1.3MPA compared with the mode of de-normal butane tower，Reduce the operating temperature of de-normal butane tower，Reduce the supply cost of steam，Thus reducing the production cost of enterprise，Improve the economic benefit of enterprise.
Accompanying drawing explanation
