Abstract

The invention discloses a defoaming agent and a preparation method thereof. The defoaming agent comprises the following components by weight: 30-50 parts of polyether, 20-30 parts of polyol, 5-10 parts of methylene diphenyl diisocyanate, 5-8 parts of calcium carbonate, 3-7 parts of poly methyl phenyl siloxane and 1-2 parts of ferric chloride. The prepared defoaming agent is high in safety, can has good defoaming effect in the case of a less addition amount, and can be applied to defoaming of the oil field.

Description

A kind of defoamer and preparation method thereof
Technical field
The invention belongs to Petroleum Refining Additives field, particularly a kind of defoamer and preparation method thereof.
Background technology
Oil mainly, by the compositions of mixtures of various aliphatic hydrocarbons, aromatic hydrocarbon and cycloalkane, belongs to fossil fuel, can be used as fuel oil and gasoline, is non-renewable energy resources.
Along with oil is exploited, the oil pressure in oil field constantly reduces, and need to improve by setting-out or gas in oil well the yield of oil.Therefore along with the prolongation of recovery time, the composition that draws up water in next liquid in exploitation is increasing, simultaneously owing to containing various surface reactive materials in crude oil, as aphthenic acids, aliphatic acid, colloid, asphalitine etc., they can be adsorbed on oil-water interfaces or gas-liquid interface, liquid pearl and bubble are had to stabilization, produced thus the problems such as original emulsification and foaming, cause oil therefrom to separate.
Existing defoamer has many types, the most frequently used amide-type, silicone based, high-carbon fatty alcohol class and polyethers etc. of mainly containing.In process due to oil extraction, have hot environment, but a lot of defoamer often at high temperature can not be brought into play froth breaking effect well, need to increase addition, therefore needs a kind of auxiliary agent just can under low concentration with good defoaming effect.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of defoamer and preparation method thereof, the defoamer that the present invention makes is safe, can in the situation that addition is few, have good froth breaking and press down bubble effect.
Object of the present invention can be achieved through the following technical solutions:
A kind of defoamer, made by the component that comprises following weight portion:
Polyethers 30-50 part,
Polyalcohols 20-30 part,
Methyl diphenylene diisocyanate 5-10 part,
Calcium carbonate 5-8 part,
PSI 3-7 part,
Iron chloride 1-2 part.
Described component also comprises 0-2 part Graphene.
Described polyethers is selected from one or more in polyoxyethylene polyoxypropylene propylene glycol, polyoxyethylene polyoxypropylene glycerin ether, polyoxyethylene polyoxypropylene pentaerythrite ether, octadecanol polyoxyethylene polyoxypropylene block type ether and NPE.
Described polyalcohols is one or both the mixing in polyethylene glycol and polyvinyl alcohol.
The relative molecular weight of described polyethylene glycol is 4000-6000.
A preparation method for defoamer, the method comprises the following steps:
(1), by polyethers 30-50 part, polyalcohols 20-30 part, methyl diphenylene diisocyanate 5-10 part, PSI 3-7 part, under 65-90, add and in high pressure homogenizer, mix 1-2 hour;
(2) by adding calcium carbonate 5-8 part, iron chloride 1-2 part and 0-2 part Graphene vortex blender to stir in the product of step (1), obtain defoamer.
The first paragraph homogenization pressure of described high pressure homogenizer is 17-20MPa, and second segment homogenization pressure is 3-4MPa.
beneficial effect:
(1) the present invention has added polyethers, polyalcohols, and add methyl diphenylene diisocyanate, the hydroxyl that can make in system that adds of methyl diphenylene diisocyanate carries out mutual cross-linking reaction, thereby the crosslinking points between each component in system is increased, and the stability of whole system has also improved the antifoam performance of product when increasing.
(2) the present invention has added calcium carbonate to improve the permeability of oil-bearing layer rock, makes product of the present invention in having good antifoam performance, can increase the extract content of crude oil.
(3) defoamer of the present invention is safe, has good froth breaking and presses down bubble effect, all has and well presses down bubble effect for various mink cell focuses, light oil, still has good dispersiveness and defoaming in the situation that addition is few.
(4) iron chloride add the catharsis that plays water-oil separating, improved extract content.
Detailed description of the invention
The method of testing of antifoam performance: first crude oil is packed in circulation bubbling instrument, then open temperature detect switch (TDS), by heating crude oil, ON cycle pump, treat that foam rises to 300ml place, add respectively the defoamer in the embodiment 1-3 of equal quality, record the foam volume V variation of t in time.It is longer that foam reaches time at 300ml place again, proves that defoaming effect is better.
The method of testing of comparative example: first crude oil is packed in circulation bubbling instrument, then open temperature detect switch (TDS), by heating crude oil, ON cycle pump, treat that foam rises to 300ml place, add the defoamer in quality and the embodiment 1-3 of polyoxyethylene polyoxypropylene propylene glycol identical in quality, record the foam volume V variation of t in time.It is longer that foam reaches time at 300ml place again, proves that defoaming effect is better.
