Abstract
The present invention relates to a method of treating aqueous fluid and apparatus therefor. The method comprises adding an organic compound to a mass of aqueous fluid comprising at least one Kinetic Hydrate Inhibitor (KHI). The organic compound comprises a hydrophobic tail and a hydrophilic head. The hydrophobic tail comprises at least one C—H bond and the hydrophilic head comprises at least one of: a hydroxyl (—OH) group; and a carboxyl (—COOH) group.
Claims20
A method of treating aqueous fluid, comprising:
- adding an organic compound to a mass of aqueous fluid that had been provided with at least one Kinetic Hydrate Inhibitor (KHI), wherein the organic compound comprises a hydrophobic tail and a hydrophilic head, wherein the hydrophobic tail comprises at least one C—H bond, and wherein the hydrophilic head comprises at least one of:
- a hydroxyl (—OH) group and a carboxyl (—COOH) group, whereby at least a part of the KHI transfers from the mass of aqueous fluid to a separate phase formed by the organic compound;
- and
- after the step of adding the organic compound to the mass of aqueous fluid, physically removing from the mass of aqueous fluid the separate phase formed by the organic compound and transferred KHI,
- wherein the organic compound comprising at least one of:
- an alcohol having the general formula R—OH, where R has the formula CnHm, the alcohol having a carbon number of at least 6 and no more than 12;
- a glycol ether having a carbon number of at least 6 and no more than 9;
- and
- a carboxylic acid having a carbon number of no less than 5 and no more than 9.
