Description
Technical field
The invention belongs to petrochemical industry, be specifically related to a kind of residual hydrogenation Scale inhibitors and preparation method thereof.
Background technology
Along with national economy increases the continuous increase to petroleum products demand rapidly, in recent years, riverine and coastal refinery of China starts a large amount of processing import crude oil, most employing middle-eastern crude.The feature that middle-eastern crude sulphur, nitrogen content and heavy metal content are higher, therefore makes to face more difficulty to its processing, the particularly processing of its residual oil.Hydrogenation process has the hydro-upgrading effect to metal, sulphur, oxygen, nitrogen and halogen compounds that Downstream processing is harmful in unsaturated compound in stable raw material, cleaning raw material.For downstream process device optimization of raw material structure, increase device operation handiness, meet the requirement of more and more harsh environmental legislation, improve the economic benefit of refinery to greatest extent, residual hydrogenation technology becomes the important means and prevailing technology that realize this purpose.But in the process cleaned with upgrading at residual hydrogenation, the heaviness of raw material can cause the fouling of hydrogenation heat exchanger and reactor bed, the tendency of coking increases.The coking of raw material interchanger can have a strong impact on the heat exchange efficiency of raw material, increases process furnace load, increases energy expenditure, reduces the treatment capacity of device raw material; Beds coking can make bed pressure drop increase, and even can block bed, device can be caused to be forced to stop work, the economic benefit of device is affected time serious.
At present, the method for the coking of solution equipment, fouling problem mainly contains two kinds.One is Processes and apparatus method, mainly by increasing utility appliance, improves technical process and operational condition, controls the approach such as stock oil character index and realizes; Another kind is chemical process, is typically employed in stock oil to add a certain amount of Scale inhibitors to suppress, delay the formation of burnt dirt in equipment surface.Do not change technical process because using Scale inhibitors to have, do not affect normal running, filling is convenient, flexibly, the advantage such as fund input is few, return period is short, become most economical, the effective ways that effectively solve equipment coking and fouling problem, meet device long-term operation at present.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of residual hydrogenation Scale inhibitors.
Another object of the present invention is to the preparation method of openly above-mentioned Scale inhibitors.
Technical scheme: in order to reach foregoing invention object, the present invention is specifically achieved like this: a kind of residual hydrogenation Scale inhibitors, comprises the component of following weight percent: the organic solvent of 10 ~ 30%, the ashless phosphoric acid ester of 10 ~ 25%, 10 ~ 25% p-di-iso-octyldiphenylamine, the heterogeneous ring compound of 10 ~ 20% and the calcium alkylbenzenesulfonate of 10 ~ 20%.
Wherein, described organic solvent is heavy aromatics, gasoline, diesel oil, kerosene or solvent oil.
Described ashless phosphoric acid ester obtains with reacting ethylene oxide after being reacted by polyisobutene and thiophosphoric anhydride again.
Wherein, described heterogeneous ring compound is benzotriazole or alkyl imidazoline derivatives.
The method preparing above-mentioned residual hydrogenation Scale inhibitors is: get each raw material by formula rate, normal pressure, at 60 ~ 80 DEG C, mix and blend 2 ~ 4 hours.
Beneficial effect: compared with conventional art, the present invention reaches the effect suppressing fouling and removing part to form dirt, thus ensure the heat exchange efficiency of interchanger and stable, the long-term operation of device, the present invention to residual oil hydrocatalyst without any detrimental effect, do not affect their activity and stability, simultaneously the present invention, oil soluble is good, viscosity is suitable for, easy to use, the corrosion-free effect of the low equipment to residual hydrogenation equipment of addition.Preparation method's science of the present invention, without any pollution.
