Agricultural extraction products and processes

Abstract

The inventive developments disclosed in this application include the following features and combinations thereof: extracting oil from spent bleaching earths for animal feed; using earths and acid water as soil amendment/fertilizer; efficient extraction of substances valuable to plants, animals, and humans from plant, animal, and fish oil soapstock, especially using the “interphase” emulsion from soapstock acidulation; use of “black paste” from oil refining as fertilizer component (nutrient source); use of interphase from agricultural oil refining, especially refining of non-degummed oils, as animal feed; use of “oil refining by-products to fertilizers” process and/or KOH refining in conjunction with “Miscella”-type hexane refining or “Zenith” process refining; fertilizers containing silica/silicates from by-products of agricultural oil refining; use of higher-sodium oil refining by-products as fertilizer for sodium-tolerant plants; using by-products of sugar beet refining as nutrient source; agriculturally useful potassium soaps from oil refining; products of the refining of non-degummed agricultural oils having useful biocidal or other biological properties; the use, as a feed additive, of potassium soapstock from the caustic refining of agricultural oils using a potassium caustic (KOH), especially with non-degummed oils, which has unexpected advantages over the use of soapstock from sodium caustic (NaOH) refining, especially from degummed oils.

1 . The processing of spent bleaching earths from agricultural oil refining characterized by extracting oil from spent bleaching earths for animal feed or using earths and acid water as soil amendment/fertilizer. 
     
     
         2 . A method of obtaining biochemicals including biopharmaceuticals by extracting said biochemicals from plant, animal, and fish oil refining soapstock, especially using the “interphase” emulsion from soapstock acidulation. 
     
     
         3 . A method of obtaining nutrients comprising using black paste from agricultural oil refining as a fertilizer component. 
     
     
         4 . An animal feed or feed additive derived from the interphase from agricultural oil refining, especially refining of non-degummed oils. 
     
     
         5 . Use of “oil refining by-products to fertilizers” process and/or potassium hydroxide (OH) refining in conjunction with “Miscella”-type hexane refining or “Zenith” process refining of agricultural oils. 
     
     
         6 . A fertilizer product containing silica/silicates and made from by-products of agricultural oil refining. 
     
     
         7 . A fertilizer made from by-products of agricultural oil refining using sodium containing caustic for use on sodium tolerant crops.

         11 . The use, as a feed additive, of potassium soapstock from the caustic refining of agricultural oils using a potassium caustic, especially with non-degummed oils, whereby spoilage is reduced.
