Abstract
The invention discloses a coking-delaying anti-coking yield increasing additive which comprises the following components in percentage by weight: 25.2-27.5% of T154, 1.5.5-17% of alkyl benzene sulfonic acid, 6.3-9.5% of organic amine, 3-7.2% of alkylamide and 43-48% of solvent. According to the invention, all used raw materials are resistant to high temperature, oxidation, scaling and corrosion, and good in dispersing performance; when injected into raw oil, the coking-delaying anti-coking yield increasing additive can be used to prevent coking in a high-temperature high-pressure pipeline with alternating-current speed, also play a certain role in dissolving coke after entering the bottom of a coke tower, has an anticorrosion effect for steel materials of inner walls of the pipeline and the tower, and has the advantages of delaying coking time and increasing the recovery rate of light oil. The raw materials of the coking-delaying anti-coking yield increasing additive are free from toxic and harmful components, have no adverse influence on downstream products, and cannot cause secondary pollution to the environment.
Description
Technical field
The invention belongs to oil refining and increase income the agent field, specifically anti-Jiao of a kind of delayed coking increases income agent.
Background technology
The refinery with crude oil through atmospheric and vacuum distillation, after the part lightweight oil distillated, the remaining dregs of fat are the 60-75% that residual oil accounts for the crude oil total amount, delayed coking then is a kind of method of residual oil deep processing, and it is by high temperature residual oil to be generated coking gas, gasoline as the raw material cracking, diesel oil, the product that wax oil and coke etc. can directly utilize, this technique belong to low-cost, the residual oil treatment process of high yield.In whole technique, delayed coking is the key of flow process, adds the anti-scorch generation that agent can reduce coke and dry gas that increases income in raw material residual oil, increases liquid product yield, and equipment is played certain anti-corrosion function, receives larger economic benefit and social benefit.
Usually there is certain problem in the agent that increases income of prior art, cause coking and fouling because of high temperature oxidation easily, the residual oil green coke is serious in the coking tower, device is subject to corrosion to a certain degree, has increased the cleaning frequency of device, has not only brought trouble to production, frequent washing unit, caused the damaged probability of device, the life-span of device will reduce, and then affects normally carrying out of producing.If things go on like this, the rate of recovery of lightweight oil must descend.
Summary of the invention
The object of the present invention is to provide anti-Jiao of a kind of delayed coking to increase income agent.
Purpose of the present invention can be achieved through the following technical solutions:
Anti-Jiao of a kind of delayed coking increases income agent, it is characterized in that comprising the moiety of following weight percent: T154 25.2-27.5%, alkyl benzene sulphonate (ABS) 15.5-17%, organic amine 6.3-9.5%, alkylamide 3-7.2%, solvent 43-48%.
The present invention includes the moiety of following proportioning: T154 26%, alkyl benzene sulphonate (ABS) 16%, organic amine 8%, alkylamide 5%, solvent 45%.
Described solvent is diesel oil or kerosene.
Preparation method of the present invention is:
(1) solvent, T154, alkyl benzene sulphonate (ABS), alkylamide are added reactor successively, stirring is warming up to 240-250 ℃, collect simultaneously the phlegma of steam, then oil-soluble material in the phlegma is passed back into still, the water of collecting is injected test tank, continue 2h, be cooled to 50 ℃ and obtain intermediates;
(2) add organic amine and stirring in the intermediates that step (1) obtains, reaction 1-3h obtains increasing income agent.
Beneficial effect of the present invention: raw material used in the present invention is for having high temperature resistant antioxygen, ant-scaling, anticorrosive, the various compositions that dispersing property is good, after injecting stock oil with it, in High Temperature High Pressure, exchange and prevent in the fast pipeline that coking from generating, enter at the bottom of the coke drum, also played certain molten burnt effect, also play simultaneously the preservative activity to pipe, inner wall of tower steel, postponed scorch time, increased the rate of recovery of lightweight oil.Advantages of nontoxic raw materials evil composition of the present invention has no adverse effects to derived product, can not cause secondary pollution to environment.After using the present invention to increase income agent, the rate of recovery of lightweight oil significantly improves, and coking gas and coke yield descend, and equipment is played certain anti-corrosion function.Receive larger economic benefit and social benefit.
