Abstract
The present invention relates to a viscosity reducer which is used when oil is collected, conveyed and treated. The viscosity reducer is characterized in that the viscosity reducer is prepared by a blending method. The viscosity reducer contains 40 to 55 wt% of lignine, 12 to 16 wt% of AES (detergent), 7 to 10 wt% of polypropylene/ polyethylene acylamide or triethanolamine, 2.5 to 5 wt% of sodium tripolyphosphate, 5 wt% of sodium hydroxide and water as the rest. The viscosity reducer for oil has the advantages of stable raw materials, high product viscosity reduction rate of 78%, innocuity, harmlessness and no odor, can lower a wax melting point by 3 to 5 DEG C, is easy to dissolve into water, and is very convenient in use.
Description
The present invention relates to tensio-active agent, particularly a kind of viscosity reducing agent for petroleum.
In order to gather, carry, to handle oil and cleaning oil well and pipe-line equipment, need use properties good, both had the viscosity reducing agent for petroleum of viscosity reduction, pour point depression ability.Existing tensio-active agent, as CN1031490 " a kind of method of making hydrocarbon surfactants " is to adopt fatty acid, amino acids, vegetable wax class, phospholipid, and in the alkyl, fragrant base class material one or more, in alkaline aqueous solution, react or composite forming with a certain proportion of black liquid resin, its production method is subjected to the influence of black liquor composition, wayward, the performance of the finished product is still undesirable.
It is stable to the purpose of this invention is to provide a kind of raw material, is easy to preparation, functional, safe viscosity reducing agent for petroleum easy to use.
For this reason and the invention viscosity reducing agent for petroleum, the xylogen that contains 40-55% (weight), the poly alkyl alcohol oxyethane ether sulfuric ester (AES) of 12-16% (weight), polyacrylamide or the trolamine of 7-10% (weight), the tripoly phosphate sodium STPP of 2.5-5% (weight), the sodium hydroxide of 5% (weight), all the other are water.
Optimum formula of the present invention is to contain the xylogen of 50% (weight), the poly alkyl alcohol oxyethane ether sulfuric ester of 15% (weight), the polyacrylamide of 10% (weight) or trolamine, the tripoly phosphate sodium STPP of 3% (weight), the sodium hydroxide of 5% (weight), all the other are water.
Viscosity reducing agent for petroleum effective ingredient about 50% of the present invention, viscosity break ratio reaches 78%, can reduce wax fusing point 3 to 5 degree, and is very easily water-soluble, and nontoxic, has no irritating odor, harmless.
Embodiment 1, method is blent in employing, and 50kg sodium hydroxide and 285kg water are added in the reactor, is warming up to 70-75%, add the 400kg xylogen, constantly be stirred to whole dissolvings, be cooled to 40 ℃, add 160kg poly alkyl alcohol oxyethane ether sulfuric ester respectively, 80kg polyacrylamide and 25kg tripoly phosphate sodium STPP, stirred 30-40 minute, and reduced to room temperature, can get the viscosity reducing agent for petroleum finished product by blowing.
Embodiment 2, and with 50kg oxygen sodium oxide, 160kg water, 550kg xylogen, 120kg poly alkyl alcohol oxyethane ether sulfuric ester, 70kg trolamine, 50kg tripoly phosphate sodium STPP blend into the viscosity reducing agent for petroleum finished product by embodiment 1 method.
Embodiment 3, and with 50kg sodium hydroxide, 170kg water, 500kg xylogen, 150kg poly alkyl alcohol oxyethane ether sulfuric ester, 100kg polyacrylamide, 30kg tripoly phosphate sodium STPP are made viscosity reducing agent for petroleum by embodiment 1 method.
