Description
Technical field
The invention belongs to function Field of Fine Chemicals, and in particular to a kind of dosage is small, extends adding for device fouling period
Hydrogen antisludging agent and preparation method thereof.
Background technique
Oil product demand is continuously increased as national economy increases rapidly, in recent years, the refining of China's riverine and coastal
Factory starts a large amount of processing import crude oil, and major part uses middle-eastern crude.Middle-eastern crude sulphur, nitrogen content and content of beary metal are higher
The characteristics of so that it is processed, particularly the processing of its residual oil face it is more difficult.Hydrogenation process, which has, stablizes raw material
In unsaturated compound, the harmful metal of Downstream processing, sulphur, oxygen, nitrogen and halogen compounds are added in cleaning raw material
Hydrogen modification effect.More and more harsh for the optimization of raw material structure of downstream process device, the flexibility for increasing device operation, satisfaction
The requirement of environmental legislation, the economic benefit for improving refinery to the maximum extent, residual hydrogenation technology is at weight for this purpose
Want means and prevailing technology.
However during residual hydrogenation is cleaned with modifying, the heaviness of raw material will lead to hydrogenation heat exchanger and reactor
The tendency of fouling, the coking of bed increases.The coking of raw material heat exchanger can seriously affect the heat exchange efficiency of raw material, and it is negative to increase heating furnace
Lotus increases energy consumption, reduces the treating capacity of device raw material；Catalyst bed coking can be such that bed pressure drop increases, or even can block up
Bed is filled in, device is can lead to when serious and is forced to stop work, the economic benefit of device is made to be affected.
Currently, solve equipment coking, fouling problem method there are mainly two types of.One is Processes and apparatus methods, mainly
It is to improve process flow and operating condition by increasing ancillary equipment, controls the approach such as raw material oil nature index to realize；It is another
Kind is chemical method, is typically employed in feedstock oil and a certain amount of antisludging agent is added to inhibit, delay burnt dirt in equipment surface
It is formed.Because use antisludging agent have do not change process flow, do not influence normal operating, filling it is convenient, flexibly, capital investment it is few,
The advantages that return period is short, become at present it is most economical, efficiently solve equipment coking and fouling problem, meet device long period
The effective ways of operation.But partial hydrogenation cracking unit high-pressure air cooler a large amount of FeS deposition occurs and tube bank corrosion is existing
As causing high-pressure air cooler cooling efficiency to decline, on-stream time shortens；Tube failure is revealed when serious, and device is had to non-meter
It draws and stops work, directly affect the safety in production and economic benefit of device.The side taken at present for this kind of corrosion and fouling, the country
Method is that a certain amount of antisludging agent is added in feedstock oil.Currently, the type of antisludging agent is more, performance difference is also bigger, ideal
Antisludging agent should be that a kind of enough effects are good, dosage is small, price is low, heat exchanger and production flow line will not be tied within certain period
Dirt, and the antisludging agent to the catalyst performance being hydrocracked without negative effect.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide, a kind of dosage is small, extends device knot
The dirty period adds hydrogen antisludging agent.
Another object of the present invention is to provide above-mentioned plus hydrogen antisludging agent preparation methods.
Technical solution: in order to achieve the above object of the invention, what the present invention was specifically performed by: a kind of dosage is small, prolongs
The growth device fouling period adds hydrogen antisludging agent, the component including following parts by weight: 20 ~ 30 parts of ashless phosphate, 30 ~ 40 parts
Propyl alcohol, 5 ~ 10 parts of paraffin, 1 ~ 5 part of calcium stearate, 1 ~ 5 part of stearic acid, 5 ~ 15 parts of dihydroquinoline, 10 ~ 15 parts of N,
N '-diphenyl-para-phenylene diamine and 5 ~ 10 parts of oleic acid octadecylamine.
Wherein, the ashless phosphate includes polyisobutene succinimide, polyisobutylene succinic acid ester or polyisobutene
Ashless phosphate.
Prepare the dosage is small, extend the device fouling period plus hydrogen antisludging agent, measure ashless phosphate, third by formula
Alcohol, paraffin, calcium stearate, stearic acid are heated to 60 ~ 65 DEG C of 30 ~ 40min of heating, the rear dihydroquinoline that formula ratio is added, N, N '-
Diphenyl-para-phenylene diamine and oleic acid octadecylamine are warming up to 75 ~ 80 DEG C of progress reheatings, heat 40 ~ 50min, and reflux 20 ~
Be cooled to room temperature after 30min to get.
Wherein, the zeolite that total mixture volume 2 ~ 3% is added in the secondary heating process carries out defervescence.
The utility model has the advantages that the present invention, compared with traditional technology, tradition plus hydrogen antisludging agent work as the constant situation of feedstock oil internal circulating load
Under, it can only guarantee heat exchanger and the pipeline non-scaling in 2 years；After provided by the invention plus hydrogen antisludging agent is added, it is ensured that 4 years
Within non-scaling.
