SYSTEM AND METHOD FOR RECYCLING USED OIL

摘要

A method, in an embodiment, that includes receiving an oil having particulates and a first turbidity; selecting an agglomeration aid that includes a carboxylic acid; and mixing the oil with a sufficient quantity of the agglomeration aid for a sufficient time at a sufficient temperature so as to result in a product having a second turbidity of at least 25% less than the first turbidity.

主权项

1. A method comprising:
receiving an oil comprising particulates;
wherein the oil has a first turbidity; selecting an agglomeration aid,
wherein the agglomeration aid comprises a dicarboxylic acid having a structure according to formula (I) wherein R is selected from the group consisting of an alkane group, an alene group, an alkyne group, an alkanol group, an aryl group, a hydroxyalkane, a hydroxyalkene, a hydroxyalkyne and a carboxylic acid group, wherein R has about 1 to about 20 carbon atoms; mixing the oil with a sufficient quantity of the agglomeration aid for a sufficient time at a sufficient temperature so as to result in a product having a second turbidity of at least 25% less than the first turbidity.
