Example Embodiment
[0034] Example 1
[0035] (1) Hydration degumming
[0036] ①Phosphoric acid degumming
[0037] Pump the crude rubber seed oil into the refining pot and heat, but not higher than 60°C. According to the quality of the crude oil, add edible-grade phosphoric acid with a concentration of 85% in oil weight of 1‰. After thorough stirring, the temperature is raised to about 80°C. 9% of 85-88 ℃ hot water, add water while stirring, all the hot water is added in about 15 minutes. After adding water, continue to stir for 30 minutes, and adjust the oil temperature to about 85°C. When the rubber particles are completely formed and are in a good separation state from the oil, stop stirring and let stand for 6 hours to release the oil feet.
[0038] ②Washing with alum: After releasing the hydrated oil from the oily feet, adjust the oil temperature to 75℃. Take alum with oil weight of 1‰ and add it to water with oil weight of 8-9%, heat it to fully dissolve the alum, and finally adjust the ...

[0065] Example 2
[0066] (1) Hydration degumming
[0067] ①Phosphoric acid degumming: The phosphoric acid added according to the quality of the crude oil is edible-grade phosphoric acid with a concentration of 85% by weight of 3‰, and the hot water added is hot water at 85-88°C with a weight of 12% of the oil. example 1.
[0068] ②Alum washing: adjust the oil temperature to 80℃. Take alum with an oil weight of 3‰ and add it to water with an oil weight of 12%, stop stirring and let it stand for 8 hours, and the rest are the same as in Example 1.
[0069] (2) Vacuum dehydration
[0070] The flow is adjusted to 2.2M 3 / h, and the rest are the same as in Example 1.
[0071] (3) Adsorption decolorization
[0072] Adjust the pressure to 0.3MPa, not more than 0.3MPa, and adjust the oil input to the decolorization tower to 1.8M 3 / h, keep the pressure of the leaf filter between 0.25MPa, so that the flow of the whole system is balanced; when the working pressure of the filter r...

[0075] Example 3
[0076] (1) Hydration degumming
[0077] ①Phosphoric acid degumming: The phosphoric acid added according to the quality of the crude oil is food grade phosphoric acid with a concentration of 2‰ of oil weight and a concentration of 85%, and the hot water added is 85-88 ℃ hot water with an oil weight of 9.5-10.5%, let stand for 7 hours, and the rest Same as Example 1.
[0078] ②Alum washing: adjust the oil temperature to 80℃. Take alum with an oil weight of 2‰, add it to water with an oil weight of 9.5-10.5%, stop stirring and let it stand for 7 hours, and the rest are the same as in Example 1.
[0079] (2) Vacuum dehydration
[0080] The flow is adjusted to 1.8M 3 / h, and the rest are the same as in Example 1.
[0081] (3) Adsorption decolorization
[0082] Adjust the pressure to 0.3MPa, not more than 0.3MPa, and adjust the oil input to the decolorization tower to 1.65M 3 / h, keep the pressure of the leaf filter between 0.225MPa, so that the flow of the...
