Description
Technical field
Water lettuce plant viscosity reductant of the present invention and production method belong to oil field, particularly a kind of water lettuce plant that is used for is sent out effect liquid attenuating viscosity of crude, be applied in processes such as petroleum crude oil oil recovery, transportation, oil refining, storage, can effectively lower the water lettuce plant viscosity reductant and the production method of viscosity of crude.
Background technology
Petroleum crude oil is many to be present in the stratum with the viscous crude form, and the high viscosity viscous crude is up to more than 200,000 CP, and the low viscosity viscous crude is generally also between 10,000 CP.Because the viscosity of the processing condition of recovering the oil requirement petroleum crude oil should be below 5000CP, for this reason, people must add a large amount of viscosity depressants in crude oil, to reduce viscosity.At present, the viscosity depressant of field use is many based on emulsifying agent, based on organism such as polyethers, this kind viscosity depressant is bigger to crude quality influence, when serious, will make the crude oil can't breaking emulsion and dewatering, water content in crude oil is too high, can directly cause the generation of serious accident in the oil refining process.In addition, this kind viscosity depressant is bigger to the visbreaking difference on effect of the crude oil in the different places of production, and cost is high.Viscosity depressant based on organism is big to the crude quality influence, wide spectrum, a large amount of use do not cause environmental pollution phenomenon serious to the visbreaking effect.
Summary of the invention
The objective of the invention is to avoid the deficiencies in the prior art part and a kind of secondary visbreaking and the difficult problem of dehydration repeatedly of having solved before the oil refining be provided, lower the oil refining cost, improve refinery output, adopt the mechanism of biological visbreaking, the water lettuce plant viscosity reductant of environmentally safe and production method.
The objective of the invention is to reach by following measure, water lettuce plant viscosity reductant contains following component, and the weight percent of each component is as follows:
Biochemical water lettuce plant fermented liq 20-65%,
Tensio-active agent 78-25%,
Liquid silicone 2-15%.
Its activity performance index is as follows: water wet type contact angle＜60 °, medium-sized moist type=80-130 °, oil-wet type contact angle＞130 °.
The process of making of biochemical water lettuce plant fermented liq is the tap water that adds gross weight 25-65% after fresh water lettuce is pulverized, it is worn into slurries, remove wherein cellulosic impurity with 40 purpose screen filtrations then, in filtrate, add millesimal subtilis or lactobacillus, fermented 4-6 days in 15-35 ℃ of close covering, treat that fermented liquid is savory and send, promptly get the water lettuce plant fermented liq.
Tensio-active agent can adopt polyoxyethylene nonylphenol ether, fatty alcohol-polyoxyethylene ether, alkylbenzene sulfonate, sulfonated petro-leum, alkyl dimethyl trimethyl-glycine a kind of, or at least a mixture.
Liquid silicone can adopt the polyethers organosilicon, anion organosilicon, amido silicon oil, methyl-silicone oil, containing hydrogen silicone oil a kind of, or at least a mixture.
The production method of water lettuce plant viscosity reductant comprises the steps:
Biochemical water lettuce plant fermented liq 20-65%,
Tensio-active agent 78-25%,
Liquid silicone 2-15%.
Get the water lettuce plant fermented liq of gross weight 20-65%, with gross weight tensio-active agent 5-25%, the liquid silicone of gross weight 2-15% mixes and carries out emulsification.
At 40-55 ℃, under the normal pressure, in there-necked flask, add the water lettuce plant fermented liq of gross weight 20-65%, the 5-25% that slowly adds the tensio-active agent gross weight successively, the liquid silicone of gross weight 2-15%, the limit edged stirs, and is incubated 40-55 ℃, stirred 1-2 hour, stir, promptly get opaque faint yellow emulsus mucus, surveying its viscosity in the time of 25 ℃ is 250-350mpa.s.
The present invention is to be the made tensio-active agent of raw material with the water lettuce, and its activity performance is that index is a water wet type contact angle＜60 °, medium-sized moist type=80-130 °, and oil-wet type contact angle＞130 °.
The present invention is effective and stable performance to the visbreaking of petroleum crude oil, solidification phenomenon can not take place in crude oil through visbreaking basically in transportation, storage process, a difficult problem that has solved the preceding secondary visbreaking of oil refining and repeatedly dewatered, lowered the oil refining cost, simultaneously since of the present invention be the mechanism of biological visbreaking, avoid organic a large amount of use, overcome and used the various disadvantages that organism brought, had high economic benefit and social benefit.
