Abstract
The invention discloses a degumming alkali-refining method for grease, and belongs to the field of grease refinement. The degumming and alkali refining processes are performed at a same procedure, crude oil is subjected to impurity removal and heating, then is subjected to acidification reaction with solid oxalic acid and liquid phosphoric acid, and then is neutralized by using an alkali solution, so that fully-degummed coarse oil is obtained, and the coarse oil is subjected to further decoloring and deodorization, so that refined grease is obtained. The method is simple and practicable, and the degumming effect is relatively good.
Description
Technical field
The invention belongs to grease and refine field.
Background technology
Oil and fat refining refers to the process of the primary oil of impure more, easy deterioration by oxidation, unfavorable long-term storage being carried out the operations such as impurity removing, oxide removal, peculiar smell removal, pigment removal by method that is chemical or physics.In order to obtain the higher polished fat of quality, the process removing impurity and oxide compound is extremely important, these materials form peptizate with grease in primary oil, have had a strong impact on usability and the stability of grease, aborning main rely on to come unstuck to remove with the process of alkali refining.
Summary of the invention
The present invention wishes the alkali refining method that comes unstuck of the grease proposing a kind of degumming effect excellence.
Technical scheme of the present invention is as follows:
A kind of alkali refining method that comes unstuck of grease, described coming unstuck is carried out in same operation with alkali refining, its process comprises: first crude oil is sent into well heater after strainer removal solid impurity and heat, the crude oil that will be heated to thereafter 70 ~ 90 DEG C is sent in the mixing tank of insulation, the solid oxalic acid that quality is quality of crude oil 0.05% ~ 0.1% is added in described mixing tank, adding quality after low speed mixing is more wherein the liquid phosphoric acid that the content of quality of crude oil 0.05% ~ 0.1% is more than or equal to 75%, again the crude oil containing acid is sent in sour oil reactor after high-speed mixing and fully react, non-hydratable phospholipid is converted into can hydrated phospholipid, add in its backward reactor mass concentration be 10% ~ 20% sodium hydroxide solution obtain mixed solution, the amount that described sodium hydroxide solution adds should meet and can neutralize completely with the crude oil containing acid, after adding sodium hydroxide solution, described mixed solution high-speed mixing is also left standstill 10 ~ 30min, thereafter described mixed solution is sent in whizzer and carry out soap stock separation.
Herein said low speed mixing and high-speed mixing and non-limiting mixing time agitator speed, only represent the relative size of stirring intensity, the mixed effect that can desirably reach when practical application freely optionally adjusts.
Said content is more than or equal to content >=75% of phosphoric acid in 75% liquid phosphoric acid referred to herein.
The add-on of sodium hydroxide solution is by determining the method for the crude oil sampling titration containing acid.
Its preferred embodiment is: described mixed solution is after soap stock is separated, rear for the heating of light for the upper strata of gained oil mutually and hot water are mixed to get mixing oil, thereafter described mixing oil is sent in the second whizzer that to carry out water separating of oil, the upper strata oil obtained after separation sends into bleaching process again.
Another preferred embodiment of the alkali refining method that comes unstuck of above-mentioned grease is: described well heater is sent in the mixing tank of insulation after crude oil is heated to 80 DEG C.
Another preferred embodiment of the alkali refining method that comes unstuck of above-mentioned grease is: the quality of described solid oxalic acid is 0.05% of quality of crude oil, and the content of described liquid phosphoric acid is 80%, and the quality added is 0.1% of quality of crude oil.
The alkali refining method that comes unstuck of the present invention can remove the various colloids in crude oil well, and the grease phospholipids content that the grease gone out by method refining of the present invention is gone out than alkali refining method refining of generally coming unstuck is low by more than 50%.
