Abstract
The invention relates to an application of random silica copolymer which is obtained by carrying out ring opening copolymerization on cyclosiloxane and unsaturated aliphatics organic acid anhydride, and unsaturated aliphatics organic acid or ester thereof, i.e. the application of the silica copolymer on preparing the anti-foaming agent of hydrocarbon liquid. The invention provides the anti-foaming agent of the hydrocarbon liquid, wherein the silicon content of the anti-foaming agent is controllable. The anti-foaming agent has better anti-foaming effect and is especially suitable for resisting foaming for the hydrocarbon liquid sensitive to silica content.
Description
Technical field
The present invention relates to a kind of purposes of silica multipolymer, specifically, relate to a kind of purposes of the silica random copolymers that obtains through ring opening copolymer by cyclosiloxane and unsaturated aliphatic organic acid anhydride, unsaturated aliphatic organic acid or its ester,
Background technology
As everyone knows, the material that hydrocarbon liquids such as petroleum fractions, refining of petroleum and processing unit (plant) relate to, gasoline, rocket(engine)fuel, diesel oil, lubricating oil, residual oil contain non-carbon, protium usually, like sulphur, nitrogen, oxygen.Though these non-hydrocarbon compound content are very low, they have reduced the surface tension of hydrocarbon liquids, make hydrocarbon liquids be prone to produce foam.Hydrocarbon liquids is prone to produce foam will produce many disadvantageous effects to the use or the process for processing of hydrocarbon liquids.
For example, the foam of delayed coking unit material handling generation.Delayed coking is a kind of refining of petroleum technology that the residual oil drastic cracking is converted into coking dry gas, coker gasoline, coker gas oil, wax tailings and coke.The conversion reaction of this residual oil degree of depth is accomplished in coke drum.In coke drum, because gas speed is higher, a large amount of oil gas produce foam in coke drum, and foam is overflowed along with oil gas and flowed out coke drum, causes follow-up equipment coking.In delayed coking process, in order to reduce the disadvantageous effect of foam, adopt the method that reduces the coke drum useful volume usually to operation of equipment, this will increase the switching of coke drum, increase the delayed coking operation cost.
And for example, the foam that material produces in the HP separator of shortening process.HP separator is the visual plant in the hydrogenation unit, and the gas-oil mixture that reactor drum comes out is separated into gas, liquid phase separation oil and water in HP separator after cooling.Material is prone to produce foam in the HP separator, makes gas, liquid phase oil and water effectively not to be separated, and has not only reduced purity, the new hydrogen consumption of increase of hydrogen, and has increased segregational load for follow-up light pressure separator.
And for example, the foam that produces in the lubricating oil use.The oiling system of machinery is if circulating, and lubricating oil will recycle in system repeatedly.When lubricating oil receives fierce the stirring at workplace, with producing foam in the inclusion of air oil.If foam can not in time be removed, the cooling of lubricating oil descends effect, and pipeline produces vapour lock, even oil pump is found time, and causes lubricating oil under-supply, increases wearing and tearing.Because the compressibility of bubble has prolonged the time of response in the hydraulicefficiency system, impel oil pump efficient to reduce, cause misoperation.
Produce foam in order to control hydrocarbon liquids, adopt usually to add the physical and chemical performance that kilfoam changes hydrocarbon liquids.Kilfoam at present commonly used mainly contains two kinds, and one of which is ZGK 5 (being commonly called as silicone oil), and it two is the polyoxyethylene polyoxypropylene compound.But these two kinds of kilfoams respectively have certain shortcoming:
1, the silicone oil kilfoam is very effective to control hydrocarbon liquids generation foam, but different use systems is produced different spinoffs.As make that silicone content is very high in the coking distillate, and downstream unit is when the high coking distillate of this silicone content of processing, and catalyzer is poisoned easily.When silicone oil uses, also be prone to cause poisoning of catalyst in HP separator.Silicone oil dispersing property in lubricating oil product is undesirable, thereby its package stability is poor, and asks bigger to the disadvantageous effect of the air release value of hydraulicefficiency oil, has influenced the quality of oil product.
2, non-silicon kilfoam can not be eliminated the foam that light hydrocarbons liquid causes.When in heavy hydrocarbon liquid such as lubricating oil product, using, still bigger to the disadvantageous effect of air release property ability, and poor with the compatibleness of other additives, thus limited its suitability in oil product.
Therefore, provide the controlled and kilfoam that have a hydrocarbon liquids of good resistance bubble performance of a kind of silicone content just to become the technical issues that need to address of the present invention.
