Problems solved by technology

Using the traditional deacidification process to process rubber seed crude oil, because caustic soda is used to neutralize the free fatty acids in the oil, the refining yield is low, the production cost is high, and a large amount of soapstock and industrial sewage are produced, causing environmental pollution. Refining process Deacidification by plate steam distillation, because the deacidified oil is distilled in a shallow layer in the tower, it is only suitable for deacidified oil with low acid value. For deacidified oil with high acid value, fatty acid distillation is endless
Not suitable for deacidification of rubber seed oil
no economic benefit
Due to the lack of good processing technology support, the development of rubber seed industry is seriously restricted

Embodiment 1

[0035] (1) Hydration degumming

[0036] ① Phosphoric acid degumming

[0037] Pump rubber seed crude oil into the refining pot to heat, but not exceeding 60°C. According to the quality of the crude oil, add food-grade phosphoric acid with an oil weight of 1‰ and a concentration of 85%. 9% 85-88 ℃ hot water, stir while adding water, all 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, so that the colloidal particles are completely formed and in a good separation state from the oil, stop stirring, let stand for 6 hours, and release the oily feet.

[0038] ②Washing with alum: release the hydrated oil after the oily feet, and adjust the oil temperature to 75°C. Take alum with an oil weight of 1‰ and add it to water with an oil weight of 8-9%, heat it to fully dissolve the alum, and finally adjust the water temperature to 85-88°C, add it to the rapidly stirring oil, and add all the alum water...

Embodiment 2

[0066] (1) Hydration degumming

[0067] ①Phosphoric acid degumming: According to the quality of crude oil, the phosphoric acid added is food-grade phosphoric acid with an oil weight of 3‰ and a concentration of 85%, and the hot water added is 85-88°C hot water with an oil weight of 12%. Let it stand for 8 hours, and the rest will be implemented in the same way example 1.

[0068] ②Washing with alum: Adjust the oil temperature to 80°C. Get the alum of oil weight 3 ‰ and add the water of oil weight 12%, stop stirring and leave standstill for 8 hours, all the other are with embodiment 1.

[0069] (2) Vacuum dehydration

[0070] Traffic adjusted to 2.2M 3 / h, all the other are with embodiment 1.

[0071] (3) Adsorption decolorization

[0072] Adjust the pressure to 0.3MPa, not exceeding 0.3MPa, and adjust the oil intake 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 wo...

Embodiment 3

[0076] (1) Hydration degumming

[0077] ①Phosphoric acid degumming: According to the quality of crude oil, the phosphoric acid added is food-grade phosphoric acid with an oil weight of 2‰ and a concentration of 85%, and the hot water added is 85-88°C hot water with an oil weight of 9.5-10.5%. With embodiment 1.

[0078] ②Washing with alum: Adjust the oil temperature to 80°C. Get the alum of oil weight 2‰ and add the water of oil weight 9.5-10.5%, stop stirring and let stand for 7 hours, all the other are the same as embodiment 1.

[0079] (2) Vacuum dehydration

[0080] Flow adjusted to 1.8M 3 / h, all the other are with embodiment 1.

[0081] (3) Adsorption decolorization

[0082] Adjust the pressure to 0.3MPa, not exceeding 0.3MPa, and adjust the oil intake 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 whole system is balanced; when the working pressure of the filter reaches 0.225MPa, and the oi...

Abstract

The invention relates to a membrane deacidification refining method for crude rubber seed oil filler. The invention relates to a refining method for crude oil, in particular to a deacidification refining method for the crude rubber seed oil. The method comprises the following steps: a, hydration degumming; b, vacuum dehydration; c, adsorption bleaching; and d, membrane deacidification of the filler, and obtaining finished product oil. The membrane deacidification technology for the filler belongs to membrane distillation, can remove all the fatty acid in the peracid rubber seed oil, and simultaneously cannot cause loss of neutral oil so as to have high refining yield.

Description

technical field [0001] The invention relates to a method for refining crude oil, in particular to a method for deacidifying and refining rubber seed crude oil. Background technique [0002] Rubber seed is a by-product of rubber and a woody oil resource that can be exploited and utilized. But for a long time, this advantageous resource has not been effectively developed and utilized. The main reason is: because the water content of rubber seeds is about 40% after they mature, and the seeds contain lipolytic enzymes, the place where rubber seeds are produced belongs to the subtropical climate with high temperature and high humidity, and the seeds are difficult to dry in the sun. The oil in the seeds undergoes hydrolysis and rancidity under the action of lipase, and the processed crude oil has a high acid value, usually between 30-50, which can neither meet the acid value index specified by edible oil nor industrial use. Acid value index of oil. Using the traditional deacidi...
