Abstract
The utility model discloses an alkyl plant with heat recovery utilizes, include deisobutanizer and take off the normal butane tower, deisobutanizer's feed inlet is connected with deisobutanizer feed arrangement through the deisobutanizer inlet pipe, take off the discharge gate intercommunication of feed inlet through taking off normal butane tower inlet pipe and deisobutanizer of normal butane tower, be provided with the heat exchanger on the deisobutanizer inlet pipe, the discharge gate intercommunication of heat source import through taking off normal butane tower discharging pipe and taking off the normal butane tower of heat exchanger, the heat source export of heat exchanger has the device of gathering materials through the union coupling that gathers materials, the utility model discloses not only reduce the thermal waste that the result possessed of taking off after the reaction of normal butane tower is accomplished, but also reduced raw materials required steam use amount among the deisobutanizer heating deisobutanizer to reduce the manufacturing cost of enterprise, improved the economic benefits of enterprise.
Description
Technical field
This utility model belongs to heat reclaiming system technical field, relates to a kind of alkyl plant with heat energy recycle.
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 the parts such as pretreatment of raw material, reaction compression, refining, 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, 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, has had 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 with heat energy recycle of a kind of production cost that can reduce isobutyltrimethylmethane..
The alkyl plant with heat energy recycle of the present utility model, including deisobutanizer and de-normal butane tower, the charging aperture of described deisobutanizer is connected to deisobutanizer feed arrangement by deisobutanizer feed pipe, the charging aperture of described de-normal butane tower is connected with the discharging opening of deisobutanizer by de-normal butane tower feed pipe, described deisobutanizer feed pipe is provided with heat exchanger, the thermal source import of described heat exchanger is connected with the discharging opening of de-normal butane tower by de-normal butane tower discharge nozzle, the thermal source outlet of described heat exchanger is connected to material-gathering device by aggregate pipe.
nullOperation principle of the present utility model is: the raw material in deisobutanizer feed arrangement is entered in deisobutanizer by deisobutanizer feed pipe，The raw material entered in deisobutanizer is heated and reacts by deisobutanizer，Deisobutanizer reacted after product entered in de-normal butane tower by de-normal butane tower feed pipe，The raw material entered in de-normal butane tower is heated and reacts by de-normal butane tower，Take off the product after normal butane tower has reacted to be entered in heat exchanger by de-normal butane tower discharge nozzle，Heat exchanger de-normal butane tower has been reacted after the heat that possesses of product pass to the raw material in deisobutanizer to be entered into，Realize treating preheating of the raw material entered in deisobutanizer，Then entered in material-gathering device by aggregate pipe with carrying out the product after the de-normal butane tower after heat exchange has reacted wait the raw material entered in deisobutanizer.
This utility model beneficial effect: this utility model by arranging heat exchanger on deisobutanizer feed pipe, heat exchanger de-normal butane tower can have been reacted after the heat that possesses of product pass to the raw material in deisobutanizer to be entered into, realize treating preheating of the raw material entered in deisobutanizer, thus the heat that the product after de-normal butane tower has been reacted possesses has utilized, not only reduce the waste of the heat that the product after de-normal butane tower has reacted possesses, but also the steam required for decreasing deisobutanizer heating deisobutanizer Raw makes consumption, thus reducing the production cost of enterprise, improve the economic benefit of enterprise.
