Abstract
A process for preparing the feed oil from niger includes such steps as using acid to regulate pH=5-7, heating until the oil and water are layered, and oil-water separation. It features that the sodium salt of fatty acid is neutralized and hydrolzed to become non-toxic free fatty acid and its nutrients (neutral oil and phosphoride) are retained, so it is an ideal oil for feed.
Description
Technical field:
The present invention relates to a kind of method of comprehensive utilization of oil prodution industry tankage, especially a kind of method of producing feed oil with soap stock.
Background technology:
Soap stock is the tankage that vegetables oil produces when adding alkali boiling, dewaters and exceptionally mainly contains fatty acid sodium salt, neutral oil and phosphatide.Treatment process for soap stock all is to add a large amount of vitriol oils in soap stock at present, makes liquid be strongly-acid, and neutral oil and phosphatide are hydrolyzed into free fatty acids, produce commercial acid oil.Because the destruction neutral oil that this method is serious and the nutritive ingredient of phosphatide be not therefore up to now also about producing the report of feed oil with soap stock.Not only reduced value-added content of product with the soap stock manufacture with sour oil, and in this process, also will produce waste acid water and the sodium sulfate waste liquid that does not meet emission standard in a large number, environment has been polluted.And, certainly will increase the wastewater treatment expense as making it up to standard, the cost that utilizes again of soap stock is increased.
Summary of the invention:
The present invention utilizes technical problems such as cost is big again for what solve the low and soap stock of product existing in prior technology added value, provides a kind of and improves added value of product, enlarges feed resource, saves the method for producing feed oil with soap stock of edible oil resource.
Technical solution of the present invention is: a kind of method of producing feed oil with soap stock, and steps in sequence is as follows:
A. with in the acid and soap stock to pH value be 5～7;
B. be heated to the profit layering;
C. with oily water separation.
Described weak acid is phosphoric acid, and the isolated water of d step is adsorbed with the peat composed of rotten mosses.
Isolated oil under 80～100 ℃ condition, is incorporated as the calcium hydroxide of oily gross weight 0.01～1%, fully stirs homogeneous.
The profit layering that is heated to of described b step preferably is heated to 120 ℃.
The present invention neutralizes to soap stock with acid, makes it be neutral meta-acid state, and promptly pH value is 5～6, then to its heating, thus breakdown of emulsion, broken glue, reaching profit moment separates.Fatty acid sodium salt neutralizing hydrolysis in the soap stock is become nontoxic free fatty acids, and still keeping the nutritive ingredient of neutral oil, phosphatide, contain the free fatty acids that is no more than gross weight 50% in the isolating oil, moisture and volatile matter content less than gross weight 2%, all the other are neutral oil and phosphatide, are the ideal feedstuff oils.Make the added value that feed oil has not only increased whole prod with soap stock, and enlarged feed resource, saved the edible oil resource.Only produce less waste water in the whole process of production, reduced the wastewater treatment expense, especially with phosphoric acid soap stock is neutralized, the waste water that is produced can adsorb with the peat composed of rotten mosses, makes phosphate fertilizer after drying, really accomplishes zero release, pollution-free.The present invention has high economic benefit and social benefit.
Embodiment:
Embodiment 1:
A. in soap stock, add phosphoric acid, should survey its pH value in the time of adding, make PH=5;
B. will heat in reaction ax and observe through the neutral soap stock, profit moment layering when reaching 105～120 ℃ stops heating after the profit layering;
C. separating oil and water;
D. with the isolating water of peat composed of rotten mosses absorption, drying forms phosphate fertilizer.
During use isolated oil of institute and feed stirring are got final product.
Embodiment 2:
A. in soap stock, add dilute sulphuric acid, should survey its pH value in the time of adding, make PH=6;
B. will heat in reaction ax and observe through the neutral soap stock, profit moment layering when reaching 105～120 ℃ stops heating after the profit layering;
C. separating oil and water;
D. be cooled to 80～100 ℃ with physical method, and under keeping warm mode, be incorporated as the calcium hydroxide of oily gross weight 0.01～1%, fully stir homogeneous, contained acid in the oil that can further neutralize, the safe reliability of assurance life-time service feed oil.
Embodiment 3:
A. in soap stock, add formic acid, should survey its pH value in the time of adding, make PH=5～6;
B. will heat in reaction ax and observe through the neutral soap stock, profit moment layering when reaching 105～120 ℃ stops heating after the profit layering;
C. separating oil and water;
Can oil and feed be stirred as embodiment 1 during use, also can in feed, add a spot of alkaline matter, or as the e step of embodiment 2, with a little acid in the oil that neutralizes.
Claims (3)
1. method of producing feed oil with soap stock, steps in sequence is as follows:
A. with in the acid and soap stock to pH value be 5～7;
B. be heated to the profit layering;
C. with oily water separation.
2. method of producing feed oil with soap stock according to claim 1, it is characterized in that: described weak acid is phosphoric acid, and the isolated water of d step is adsorbed with the peat composed of rotten mosses.
3. method of producing feed oil with soap stock according to claim 1 and 2 is characterized in that: isolated oil under 80～100 ℃ condition, is incorporated as the calcium hydroxide of oily gross weight 0.01～1%, fully stirs homogeneous.
