Abstract
Aspects of the present invention provide methods of drying lecithin in a batch reaction, comprising the steps of obtaining a lecithin-containing material (derived from a crude refining stream) comprising 15-50% water, 10-30% acetone insoluble matter, and 10-20% free fatty acid; adding a fatty acid source (also derived from a crude refining stream) to the lecithin-containing material composition to obtain a lecithin/fatty acid reaction mixture; and blowing dry gas through the gum/fatty acid reaction mixture to obtain a resultant dried lecithin fatty acid blend having a water content of less than 2%. The resultant dried lecithin fatty acid blend may be used in asphalt or oil field applications.
Claims7
A method of incorporating fatty acid lecithin blends in asphalt applications, comprising:
- (a) obtaining a lecithin fatty acid blend, comprising:
- i. less than 2 wt % water;
- ii. between 5 and 75 wt % acetone insoluble matter;
- and
- iii. between 25 and 95 wt % free fatty acid;
- and
- (b) adding the lecithin fatty acid blend to aggregates to be used in asphalt pavements, wherein the amount of the lecithin fatty acid blend ranges from 0.25 to 3 wt % of the lecithin fatty acid blend/aggregate mixture.
