Abstract
A method for increasing removal of drag reducer additive (DRA) from liquid hydrocarbon fuel. The method comprises producing contaminated liquid hydrocarbon fuel comprising a concentration of removable DRA comprising a quantity of one or more polar groups, and contacting the contaminated liquid hydrocarbon fuel with an amount of one or more removal agents under removal conditions effective to produce a reduced concentration of the removable DRA.

A method for increasing removal of drag reducer additive (DRA) from liquid hydrocarbon fuel, said method comprising:
- producing contaminated liquid hydrocarbon fuel comprising a concentration of removable DRA comprising a quantity of one or more polar groups other than a single terminal unsaturated carbon-carbon bond;
- and,
- contacting said contaminated liquid hydrocarbon fuel with an amount of one or more removal agents under removal conditions effective to produce a reduced concentration of said removable DRA.
A method for increasing removal of DRA from liquid hydrocarbon fuel, said method comprising:
- producing contaminated liquid hydrocarbon fuel comprising a concentration of removable DRA comprising a quantity of one or more polar groups other than a single unsaturated terminal carbon-carbon bond;
- and,
- contacting said contaminated liquid hydrocarbon fuel with an amount of one or more removal agents under removal conditions effective to remove 60% or more of said removable DRA from said contaminated liquid hydrocarbon fuel, producing a reduced concentration of said removable DRA.
