Abstract
A simple process for treating petroleum acid sludge includes such technological steps as stirring the acid sludge with hot water uniformly, adding lime hydrate powder at a certain temp for reaction to separate oil from water, recovering petroleum residue for reuse, and neutralizing discharged acidic water with sodium carbonate (Na2CO3) to reuse, and features simple and feasible process, no secondary industrial dregs, and high output rate of petroleum residue.
Description
The present invention relates to a kind ofly, belong to the hydrocarbon oil refining technical field with sulfuric acid treatment petroleum fractions and treatment method of acid residuum that intermediates produced.
With sulfuric acid treatment petroleum fractions and intermediates is the old technology of using in the refining of petroleum for many years, is particularly generally adopted by each refinery in lubricating oil processing.The industrial residue that produces in this technology---acid sludge often by buried or discharging field, has caused severe contamination to environment.For solving the pollution of acid residuals of petroleum, once the treatment process of many relevant acid sludges was carried out report both at home and abroad, China patent CN1087666A had just once proposed a kind of hydrolysis process for treating of acid residuals of petroleum, though this method is feasible, existed following deficiency; (1) adopt organic emulsion splitter or organic and inorganic emulsion splitter to be used in combination, emulsion splitter composition complexity is difficult for buying; (2) sour water after settlement separate forms new industrial residue again with in the lime and produce solid calcium sulphate and discharge as residue; (3) sedimentation 1-8 hour, the work continuity was not strong, and treatment capacity is little; (4) separating back residual oil yield only is 70-77.3%.
The object of the present invention is to provide a kind of simple, economical and practical method for treating acid residuals of petroleum, by this method, acid sludge can be decomposed into the residual oil of sour water and recyclable utilization equally, no secondary industrial residue has been eliminated the pollution to environment.
Very complicated with the reaction of vitriolization petroleum fractions and intermediates, with regard to lubricating oil, for reaching the requirement of product use properties, must be with most of colloid, encircle undesirable component such as short-side chain aromatic hydrocarbon more and remove.These materials and sulfuric acid reaction mainly generate aromatic hydrocarbons sulfonic acid and colloid sulfonated bodies and excessive sulfuric acid is discharged with the waste residue form of mixture, are referred to as acid sludge.Be incorporated under the certain temperature condition fully stirring and evenly mixing when acid sludge and water mix, aromatic hydrocarbons sulfonic acid in the acid sludge and colloid sulfonated bodies and water carry out the sulfonation reversed reaction, are reduced to aromatic hydrocarbons, colloid (being commonly called as residual oil) and sulfuric acid again.During the hydrolysis acid sludge, sulfuric acid that restores from aromatic hydrocarbons and colloid and excess sulfuric acid are diluted to be dissolved in the water, and the liquid of formation is water in oil emulsion and is suspended in the simultaneous complex system of suspension in the water.Want with this system separately must add people's emulsion splitter and just can make oily water separation.
In view of the foregoing, for realizing goal of the invention, the technical scheme that the present invention takes is: acid sludge weight 2-10 hot water is doubly added in the reactor, the acid sludge that adds the discharge of sulfuric acid treatment petroleum fractions and intermediates is stirred to complete mixing, mixing temperature 20-60 ℃, the dry hydrate (CaO) that adds acid sludge weight 4-18% again, the limit edged stirs, and churning time is 5-50 minute, stops to stir afterreaction 3-10 minute, make oily water separation, bleed off sour water, get the residual oil of PH5-6, the sour water of discharge neutralizes with ordinary method, water ph value after the neutralization is 6-7, capable of circulationly uses again.
Aforesaid reaction vessel is the reactor that has agitator.The sour water of discharging after above-mentioned oily water separation soda ash (Na
2CO
3) neutralization, do not produce the secondary industrial residue.
Simple method for treating acid residuals of petroleum provided by the invention has following characteristics: the emulsion splitter that adopt (1) is a dry hydrate, is simple and easy to purchase low price; (2) technological design is reasonable, white lime is added with dry powder behind acid sludge and the water mixing again, is adapted to the separation of not emulsification or serious emulsification liquid, and it is clear to separate the back water-oil interface, and the work continuity is strong, and processing speed is fast; (3) in the mixed liquid of acid sludge and water, add an amount of dry hydrate as emulsion splitter, isolated sour water soda ash (Na
2CO
3) neutralization, no secondary industrial residue; (4) the residual oil yield can reach 90%.
Accompanying drawing is a schematic flow sheet of the present invention.
1 is the mix and blend reactor in the accompanying drawing, and 2 is in the sour water and device. Water by reinforced mouthful 5, acid sludge by It is mixed even to enter mix and blend reactor 1 for reinforced mouthful 3, and demulsifier adds by reinforced mouthful 4 subsequently; After the processing Residual oil discharge through discharging opening 6 from mix and blend reactor 1, sour water is by mix and blend reactor 1 bottom Discharge through transfer line 7 enter in the sour water and device 2 in, during nertralizer enters by reinforced mouthful 9 and device 2, Water after the neutralization enters in the mix and blend reactor 1 through pipeline 8 circulations and with new water.
The invention will be further described below in conjunction with embodiment;
Get acid sludge 100 grams, water 250 grams, white lime (CaO) 15 grams, earlier that hot water and acid sludge is even in the mixing reaction kettle for stirring and mixing, mixing the back temperature is 28 ℃, the emulsion splitter dry hydrate is added again, and the limit edged stirs, churning time is about 5 minutes, stop to stir, react oily water separation after 4 minutes, the sour water after the separation adds in the soda ash and the back pH value is 6-7, the residual oil water flushing of separating 2-3 time obtains the residual oil that pH value is 5-6.Residual oil can further utilize, as oil fuel, make tar felt etc., in the sour water and after can be recycled, eliminated environmental pollution.
