Abstract
A viscosity-reducing agent used for collecting, delivering and processing petroleum is prepared from lignin (40-55 wt.%), AES (12-16 wt.%), polyacryl ethyleneamide or triethanolamine (7-10 wt.%), sodium tripolyphosphate (2.5-5 wt.%), sodium hydroxide (5 wt.%) and water through mixing, and serves to reduce viscosity by 78% and smelting point of wax by 3-5 deg.C. Its advantages are no poison, odour and harm, and high water solubility.
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 viscosity reducing agent for petroleum of invention contains the xylogen of 40-55% (weight), the AES (dish detergent) of 12-16% (weight), poly-third ethernamine 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, contains the xylogen of 50% (weight), the AES of 15% (weight) (dish detergent), and poly-third ethernamine or the trolamine of 10% (weight), 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 160kgAES (dish detergent) respectively, poly-third ethernamine of 80kg 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 sodium hydroxide, 160kg water, 550kg xylogen, 120kgAES (dish detergent), 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, 150kgAES (dish detergent), 100kg gather third ethernamine, 30kg tripoly phosphate sodium STPP, make viscosity reducing agent for petroleum by embodiment 1 method.
Claims (2)
1, a kind of viscosity reducing agent for petroleum, it is characterized in that containing the xylogen of 40-55% (weight), the AES (dish detergent) of 12-16% (weight), poly-third ethernamine 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.
2, viscosity reducing agent for petroleum according to claim 1 is characterized in that containing the xylogen of 50% (weight), the AES of 15% (weight) (dish detergent), poly-third ethernamine or the trolamine of 10% (weight), the tripoly phosphate sodium STPP of 3% (weight).
