Description
Technical field
The present invention relates to a kind of ethene compressor cleaning media that is exclusively used in, it adds in the compressor wash oil uses.
Background technology
For preventing the fouling of ethylene device compressor system, in compressor, inject washing oil usually, washing oil can play two effects, and the first is washed away, and the dirty thing that sticks on compressor impeller and the cavity is washed away; Its two be the cooling splitting gas slow down polymerization fouling.
Chinese patent CN1217373A has pointed out a kind of scale inhibitor that can effectively suppress fouling in the petroleum refining process (refinery cracking unit).This scale inhibitor contains vistac base imine compound, tert-butyl phenol compound, polyoxy alkylene aminated compounds, organic acid acetic compounds, two inferior bigcatkin willow alkyl diamine compounds etc.
Japanese Patent JP2001181600 discloses the antitartar agents in the depropanizing tower that can be used for ethylene unit, and the heterogeneous ring compound of its employing N-substituted-amino or the heterogeneous ring compound of N-substituted-amino and hydroxy phenylic derivant are as the effective ingredient of antitartar agents.
Above-mentioned antitartar agents all non-at the ethylene device compressor system fouling develop, relatively poor so it is bigger than normal to produce consumption, or deficiency such as anti-tartar DeGrain to the cracking adaptability to raw material, have in addition the postorder device had side effects.
Summary of the invention
The technical issues that need to address of the present invention are, overcome the existing deficiency of prior art, provide a kind of strong to the cracking adaptability to raw material, the antitartar agents that anti-tartar is effective.
At first ethene cracking gas compression process and anti-tartar mechanism are studied.Before address because heaviness, the poor qualityization of cracking stock makes the serious scale effect device of compressor ordinary production.Cracking gas compressor fouling, most important reason are the polyreactions of the unsaturated hydrocarbons in the splitting gas.It is generally acknowledged that unsaturated hydrocarbons easily forms free radical under the effect of trace oxygen, photo-thermal, metal ion, chainpropagation then forms polymkeric substance.It is as follows that free radical causes the reaction process that generates cross-linked polymer:
(1) initiation of chain: RH+O
2-→ R+HOO,
The free radical R that produces is very active, continues reaction with oxygen and generates peroxide radical R+O
2-→ ROO, peroxide radical capture the H in the hydrocarbon molecules again, generate superoxide and new free radical.
(2) transfer of chain: ROO+PH-→ ROOH+R,
New free radical reacts with oxygen again, and chain is increased, and superoxide is captured the H in the hydrocarbon molecules and produced new free radical once more under the bringing out of metal ion:
ROOH—→RO·+OH·，
RO·+RH—→ROH+R·，
OH·+RH—→H
2O+R·，
(3) growth of chain: M+R-→ MR (=Mn),
(4) end stopping of chain: 2Mn-→ polymkeric substance,
R·+ROO—→ROOR，
Inject at compressor under the situation of washing oil, every section temperature out is all more than 90 ℃.Under this temperature, be enough to make unsaturated hydrocarbons to produce free radical, finish the radical chain polymerization reaction and fouling.
Antitartar agents of the present invention is researched and developed according to the mechanism of unsaturated hydrocarbon radical chain polymerization, and it mainly contains phenolic antioxidant, organo phosphorous compounds metalloid passivator, components such as amine stopper.Its anti-tartar mechanism is:
(1) antioxygenation: eliminate trace oxygen, reduce the generation of free radical;
(2) for the free radical that has formed, use the stopper terminating chain to increase, its mechanism of action is:
R is a free radical, and AH is a stopper.
A compares with R and will stablize, and be difficult for to cause new chainpropagation, but free radical A also can successive reaction go down, that is:
This is a homeostasis process, and the equilibrated result is that most free radicals are in A condition in the medium, and the minority free radical is in the R state, thereby reaches the poly-purpose of relative resistance.
(3) passive metal ionic effect: partly surperficial at compressor, form protective membrane with passivating metallic surfaces, or complexing is dissolved in the central metal ion of medium to stop the katalysis of metal ion;
The reaction product of (four) three components is disperseed peace and quiet effect in addition, and it can make polymer dispersed can not stick to equipment surface and blocking channel in the middle of medium, and the dirty thing that perhaps will stick to equipment surface is removed, and flows away with medium.
Ethene compressor cleaning media of the present invention, it is characterized in that by weight % takes by weighing phenolic antioxidant and solvent places container, heat be stirred to phenolic antioxidant complete molten after, cooling, % adds amine stopper and Organophosphorous compounds by weight, abundant stirring reaction, reduce to room temperature and promptly get the antitartar agents product after filtration, wherein phenolic antioxidant is 2～15% (weight), and organo phosphorous compounds is 10～40% (weight), amine stopper 6～30% (weight), all the other are solvent.
