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.
Claims24
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 free fatty acid component present in an amount of 15 percent or less by weight based on the total weight of the grain oil composition, and wherein the grain oil composition comprises a fatty acid alkyl ester component present in an amount of at least 5 percent by weight based on the total weight of the grain oil composition;
- and
- 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 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 free fatty acid component and the second grain oil product has a second concentration of free fatty acid component, and wherein first concentration of free fatty acid component is less than the second concentration of free fatty acid component.
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 present in an amount of at least 6 percent by weight based on the total weight of the grain oil composition;
- 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.
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 having a first fatty acid alkyl ester 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 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 grain oil composition that does not evaporate while exposing the grain oil composition to the temperature and the pressure conditions is the first grain oil product, wherein the first grain oil product has a second fatty acid alkyl ester component concentration that is less than the first fatty acid alkyl ester component concentration of the grain oil composition, and wherein the first grain oil product is a feedstock to make a final product chosen from defoamer, biodiesel, and combinations thereof.
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 having a first fatty acid alkyl ester 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 fatty acid alkyl ester component from the grain oil composition to form a first grain oil product and a second grain oil product;
- c) condensing evaporated fatty acid alkyl ester component to form the second grain oil product, wherein the second grain oil product has a second fatty acid alkyl ester component concentration that is greater than the first fatty acid alkyl ester 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, ultra-low sulfur diesel, asphalt additive, and combinations thereof.
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 a free fatty acid component, wherein the free fatty acid component is present in the grain oil composition in an amount in the range from 0.5 to 9 percent by weight based on the total weight of the grain oil composition;
- 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 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.
