Abstract
The present utility model relates to a desulphurization system apparatus in an oil-extraction plant, concretely relating to a desulphurization tower bottom heating apparatus. The desulphurization tower bottom heating apparatus comprising a desulphurization tower, and a reboiler and a circulation oil plaster cold composition on the bottom of the desulphurization tower is characterized in that a pipeline for leading into the circulation oil plaster cold composition is connected with a pipeline for leading steam into the reboiler, an out let of the reboiler is connected with a pipeline for leading out of the circulation oil plaster cold composition through a pipeline. According to the utility model, steam is replaced by circulation oil plaster as a heat power supply of the bottom of a desulphurization tower, a great deal of steam can be saved and the cost can be reduced.
Description
Technical field
The utility model relates to a kind of oil plant desulphurization system equipment, specifically is a kind of desulfurizing tower tower bottom heating device, is applicable to the catalytic unit of monoethanolamine desulphurization system.
Background technology
In catalytic cracking process, slurry oil circulates as the temperature control device at the bottom of the fractionating column, passed through with the raw material heat exchange, produce steam after, also need to cool off through cold type.In this process, not only discharge a large amount of heat, and Yin Wendu is higher and recirculated water is vaporized in a large number, causes water resource waste, circulating water quality is descended.And the monoethanolamine desulfurization regeneration system in its device, the required thermal source of its desulfurizing agent regeneration generally provides with steam.Use this method not only to consume a large amount of steam, and the generation water resource that steam consumed also is a very big numeral.
Summary of the invention
The utility model with the circulation slurry oil as desulfurizing tower at the bottom of thermal source replace steam to heat, saved steam, reduced power cost.
The following technical scheme of the concrete employing of the utility model:
A kind of desulfurizing tower tower bottom heating device, comprise desulfurizing tower, the desulfurizing tower bottom has reboiler, circulation slurry oil cold type, it is characterized in that, the slurry oil cold type pipeline that advances to circulate advances steam pipe line with reboiler and is connected, and the reboiler outlet is connected with the slurry oil cold type pipeline that goes out to circulate by pipeline.
It is about 160 ℃ that the circulation slurry oil advances the preceding temperature of cold type, can substitute fully steam as desulfurizing tower at the bottom of thermal source, formerly advance the cold type line and keep, the heat-obtaining amount can be implemented by the slurry oil amount of regulating reboiler at the bottom of the desulfurizing tower, unnecessary slurry oil advances the cold type cooling, returns tower after the mixing.Compared with prior art, the utility model has made full use of the waste heat of circulation slurry oil, has saved a large amount of steam, has reduced cost.
Description of drawings
Fig. 1 is a prior art desulfurizing tower tower bottom heating device;
Fig. 2 is the utility model desulfurizing tower tower bottom heating device;
The specific embodiment
Comparative Examples
As shown in Figure 1, a kind of desulfurizing tower tower bottom heating device comprises desulfurizing tower 7, and desulfurizing tower 7 bottoms have reboiler 6, circulation slurry oil cold type 5, and 1.0MPa steam enters reboiler 6 from admission pipeline 1, and condensed water is discharged by water outlet pipeline 2; Catalytic slurry enters circulation slurry oil cold type 5 by the slurry oil cold type pipeline 3 that advances to circulate, and cooled slurry oil is flowed out by the slurry oil cold type pipeline 4 that goes out to circulate.
Embodiment
As shown in Figure 2, adopt the pipeline 1-1 slurry oil cold type pipeline 2 that will advance to circulate to be connected with admission pipeline 1, employing pipeline 2-1 exports reboiler 6 and is connected with the slurry oil cold type pipeline 4 that goes out to circulate, and all the other and Comparative Examples are basic identical.
The circulation slurry oil enters reboiler 6 from advance to circulate slurry oil cold type pipeline 3, pipeline 1-1, and heat exchange no longer enters circulation slurry oil cold type 5 after pipeline 2-1, the slurry oil cold type pipeline 4 that goes out to circulate return, and has both replaced steam, has reduced the consumption of recirculated water again.
