Description
Technical field
This utility model relates to a kind of freshening High water cut sump oil device of application in Petrochemical Enterprises.
Background technology
The sump oil water content that sewage from oil refinery pretreatment unit reclaims is high (moisture mass percent is more than 50%), and before transformation, coking dirty oil recycling has two places to go: be that top of coke tower distillates line and makees quench oil, enters raw material surge tank V-101 as coking raw material respectively.The sump oil water content that sewage pre-treatment device reclaims high (moisture mass percent is more than 50%), mixed by the sump oil low with water content and refine into top of coke tower quench oil line or raw material surge tank V-101 freshening, mix refining ratio manually to control, control the bad operation on device and affect big, be unfavorable for device long-term operation.It is primarily present problems with.
1) sump oil enters top of coke tower and distillates line when making quench oil, require sump oil moisture (moisture mass percent is less than 10%), if moisture height easily causes top of coke tower and evaporates outlet flanges leakage, additionally sump oil does quench oil freshening affects bigger on fractionating system operation.
2) entering raw material surge tank V-101 as coking raw material, it is desirable to the moisture mass percent of sump oil is less than 5%, if moisture height, the easy water attack vibration drawing crack weld seam of pipeline causes deep fat to leak, and additionally the easy bumping of raw material surge tank affects fractionating column operation.
Utility model content
Technical problem to be solved in the utility model is the drawbacks described above for prior art, it is provided that a kind of freshening High water cut sump oil device, goal of the invention；For the High water cut sump oil that freshening sewage from oil refinery pretreatment unit reclaims, at freshening sump oil line and remove between coke cooling water line one cross-line of increase so that moisture high sump oil by coke drum cold burnt feed water in a small amount time carry out dirty oil recycling.When the little feedwater of coke drum, the sump oil of moisture higher (mass percent that water accounts for is more than 50%) is injected from the feedwater line of coke drum when the cold burnt feedwater in a small amount of coke drum.Mainly by the coke of in coke drum 400 DEG C as carrier, utilize its waste heat, the moisture in sump oil, oil point are steamed, part heavy oil is degraded, oil gas enters blowdown system and reclaims, and the most of heavy oil in sump oil divides to be stayed in coke drum with solid impurity, enters Jiao Chi with coke during decoking.Owing to it is to inject in the feedwater stage of steaming out, the operation of the other systems such as coking plant fractionating column will not be produced impact, and operate relatively simple, it is easy to control.
nullTo achieve these goals，This utility model provides a kind of freshening High water cut sump oil device，Including a freshening sump oil line、One removes coke cooling water line，The arrival end and one of described freshening sump oil line is adopted the pump housing of freshening sump oil and is connected，Described freshening sump oil line is provided with the first main control valve regulating dirty oil recycling amount、The first sub-control valve in parallel with described first main control valve，The described arrival end removing coke cooling water line and one is adopted the pump housing of coke cooling water and is connected，Described freshening sump oil line is provided with the second main control valve regulating coke cooling water amount、The second sub-control valve in parallel with described second main control valve，It is characterised by，Remove to be connected between coke cooling water line a cross-line at described freshening sump oil line with described，Described cross-line one end is connected on the pipeline after described first main control valve or the first sub-control valve，The other end of described cross-line is connected on the pipeline at described second sub-control valve place，And after being positioned at described second sub-control valve.
Above-mentioned freshening High water cut sump oil device, described cross-line is provided with control valve.
Above-mentioned freshening High water cut sump oil device, described control valve includes the first control valve and second and controls valve.Above-mentioned freshening High water cut sump oil device, described first controls valve near the first main control valve or the first sub-control valve, and described second controls the valve pipeline near the second sub-control valve place is arranged.
Above-mentioned freshening High water cut sump oil device, the port of export and a top of coke tower of described freshening sump oil line distillate line, enter the connection of raw material surge tank.
Above-mentioned freshening High water cut sump oil device, described in go to connect at the bottom of the port of export of coke cooling water line and a coke drum.
Above-mentioned freshening High water cut sump oil device, described in go the port of export of coke cooling water line to be additionally provided with a pipeline in order to be discharged by coke cooling water.
Beneficial functional of the present utility model is in that:
After modification measures comes into operation, the moisture sump oil that reclaims of sewage pre-treatment device can all obtain freshening, affects less on the operation of device simultaneously, is conducive to device long-term operation.
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail, but not as to restriction of the present utility model.
