Description
First, technical field
The present invention relates to petroleum chemical industry, and in particular to a kind of online washing fractionation tower top follows system.
2nd, background technology
In fractional distillation process is refined oil, because of fractionation tower temperature reduction, there is water mutually to occur, cause delayed coking unit fractionating column
Top is followed system salt crust and is corroded extremely serious.The phenomenon that top is followed after system salt crust, fouling is so that system pressure difference increase, petrol and diesel oil product
Product separation is unintelligible, and fractionating column rushes tower, and follow pump depletion on top, influences the safety in production of device.Existing conventional treatment method is dress
The production of drop amount is put, stream pump intake injection demineralized water is walked around on top, tower top, the ammonia that washing top is followed in system are returned with top recycle oil
Salt, washing returns to normal production after finishing.Washing process easily causes operating pressure to fluctuate, and product is unqualified, the phenomenon such as pump depletion.
3rd, the content of the invention
Regarding the issue above, the present invention provides a kind of easy for installation, simple to operate, operating stabilization, Neng Gouyou
Effect alleviation fractionation tower top follows system salt crust speed, prevents pipeline from connecing salt, reduces fractionating column top tray, tower wall and push up and follow pipeline
Extent of corrosion, and enter simultaneously water-filling oil separate online washing fractionation tower top follow system.
The purpose of the present invention is achieved through the following technical solutions：
A kind of online washing fractionation tower top follows system, and it includes fractionating column, injection point, air cooler, water cooler, rotation oil dehydration
Device, gun barrel, autocontrol valve, first pipeline, second pipeline, sewage disposal system, oil-out and delivery port, it is special
Levy is that fractionating column top side draws the pipeline with injection point, fractionating column, air cooler, water cooler, rotation oil dehydrator and profit
Knockout drum is connected by pipeline, and fractionation tower top sets oil-out, and rotation oil dehydrator Base top contact carries autocontrol valve
First pipeline, is connected with fractionating column top, and gun barrel top side draws second pipeline, and enters with first pipeline
Row connection, water-oil separating pot bottom sets delivery port；Current are passed through in injection point, are cooled down by air cooler and water cooler, cooling
Oil water mixture afterwards enters rotation oil dehydrator, and top follows oil and is back to fractionating column by first pipeline, with containing for a small amount of oil
Salt sewage enters a gun barrel, and a small amount of oil phase isolated is back to fractionating column, saline sewage by second pipeline
Into sewage disposal system.
Described online washing fractionation tower top follows system, it is characterized in that injection point be arranged on connection fractionating column and air cooler it
Between pipeline on.
Described online washing fractionation tower top follows system, it is characterized in that the oil mixing with water after being cooled down through air cooler, water cooler
Thing is 50 DEG C or so.
Described online washing fractionation tower top follows system, it is characterized in that the top after revolving oil dehydrator separation is followed W/O and contained
Amount is less than 100ppm.
Online washing fractionation tower top of the present invention follows system compared with prior art, with easy for installation, simple to operate, operating
Stabilization, can effectively alleviate fractionation tower top and follow system salt crust speed, prevent pipeline from connecing salt, reducing fractionating column top tray, tower wall
And the extent of corrosion of pipeline is followed on top, and enter water-filling oil simultaneously and separate, reduce the loss of shut-down water-flushed zone, extension on-stream time and
Equipment component service life=the characteristics of, while also have following remarkable advantage：
1st, injection point is located on the pipeline between fractionating column and air cooler, can effectively protect pump, and prevent in air cooler
Salt crust in pipeline.
2nd, by setting rotation oil dehydrator, water-oil phase separates thorough so that water content is less than 100ppm in oil phase, effectively
Improve oil quality.
3rd, by the setting of gun barrel, a small amount of oil phase in saline sewage is efficiently separated out, reduces production cost.
4th, illustrate
Fig. 1 is course floor map of the invention
