Abstract
The present disclosure is related to refining one or more grain oil composition streams (e.g., distillers corn oil or syrup) in a biorefinery to provide one or more refined grain oil products, where each grain oil product has targeted amounts of a free fatty acid component and the fatty acid alkyl ester component.
Claims20
A method of refining a grain oil composition to make one or more grain oil products, the method comprising:
- a) providing a grain oil composition obtained from a biorefinery, wherein the grain oil composition comprises a fatty acid alkyl ester component;
- and
- b) exposing the grain oil composition to temperature and pressure conditions for a time period to evaporate at least a portion of the fatty acid alkyl ester component from the grain oil composition to form a first grain oil product and a second grain oil product, wherein the first grain oil product has a first concentration of fatty acid alkyl ester component and the second grain oil product has a second concentration of fatty acid alkyl ester component, and wherein the first concentration of fatty acid alkyl ester component is less than the second concentration of fatty acid alkyl ester component, wherein the temperature is in the range from 300 to 400° F., wherein the pressure is in the range from 10 to 5000 millitorr, and wherein the time period is in the range from 1 second to 30 minutes.
A method of refining a grain oil composition to make one or more grain oil products, the method comprising:
- a) providing a grain oil composition obtained from a biorefinery, wherein the grain oil composition comprises a fatty acid alkyl ester component;
- and
- b) exposing the grain oil composition to temperature and pressure conditions for a time period to evaporate at least a portion of the fatty acid alkyl ester component from the grain oil composition to form a first grain oil product and a second grain oil product, wherein the first grain oil product comprises a fatty acid alkyl ester component present in an amount in the range from 0.5 to 5 percent by weight based on the total weight of the first grain oil product;
- and wherein the second grain oil product comprises a fatty acid alkyl ester component present in an amount in the range from 45 to 95 percent by weight based on the total weight of the second grain oil product.

A method of refining a grain oil composition to make one or more grain oil products, the method comprising:
- a) providing a grain oil composition obtained from a biorefinery, wherein the grain oil composition comprises a fatty acid alkyl ester component;
- and
- b) exposing the grain oil composition to temperature and pressure conditions for a time period to evaporate at least a portion of the fatty acid alkyl ester component from the grain oil composition to form a first grain oil product and a second grain oil product, wherein the first grain oil product has a first concentration of fatty acid alkyl ester component and the second grain oil product has a second concentration of fatty acid alkyl ester component, wherein the first concentration of fatty acid alkyl ester component is less than the second concentration of fatty acid alkyl ester component, wherein the first grain oil product comprises a free fatty acid component present in an amount in the range from 0.5 to 10 percent by weight based on the total weight of the first grain oil product;
- and wherein the second grain oil product comprises a free fatty acid component present in an amount in the range from 5 to 55 percent by weight based on the total weight of the second grain oil product.
1 more element
A method of refining a grain oil composition to make one or more grain oil products, the method comprising:
- a) providing a grain oil composition obtained from a biorefinery, wherein the grain oil composition has a fatty acid alkyl ester component concentration and a free fatty acid component concentration;
- b) exposing the grain oil composition to temperature and pressure conditions for a time period to evaporate at least a portion of the free fatty acid component and at least a portion of the fatty acid alkyl ester component from the grain oil composition, wherein the grain oil composition that does not evaporate while exposing the grain oil composition to the temperature and the pressure conditions is a first grain oil product, wherein the first grain oil product has a fatty acid alkyl ester component concentration that is less than the fatty acid alkyl ester component concentration of the grain oil composition, wherein the first grain oil product has a free fatty acid component concentration that is less than the free fatty acid component concentration of the grain oil composition, and wherein the first grain oil product is a feedstock to make a final product chosen from food grade oil, defoamer, bio-based lubricant, emulsifier, biodiesel, and combinations thereof;
- c) condensing evaporated free fatty acid component and evaporated fatty acid alkyl ester component to form a second grain oil product, wherein the second grain oil product has a fatty acid alkyl ester component concentration that is greater than the fatty acid alkyl ester component concentration of the grain oil composition, wherein the second grain oil product has a free fatty acid component concentration that is greater than the free fatty acid component concentration of the grain oil composition, and wherein the second grain oil product is a feedstock to make a final product chosen from diesel via catalytic cracking, defoamer, rubber additive, ultra-low sulfur diesel, asphalt additive, and combinations thereof.
