Abstract
The present invention generally relates to methods for removing an organic deposit or for inhibiting deposition of deposit-forming comprising contacting a cleaning composition or an anti-coking composition with a surface. The surface can have an organic deposit or be susceptible to forming an organic deposit and the surface can be in contact with a liquid containing organics. The liquid can be produced from a thermal recovery system, and the surface can be an internal surface of a piece of steam-generating or vapor-generating equipment.
Claims27
A method for removing an organic deposit or for inhibiting deposition of deposit-forming organics comprising contacting a cleaning composition with a surface, the surface having an organic deposit or being susceptible to forming an organic deposit and the surface being in contact with a liquid containing organics, the liquid being produced from a thermal recovery system, and the surface being an internal surface of a piece of steam-generating or vapor-generating equipment;
- wherein the cleaning composition comprises an alkoxylated polymer, an alkoxy alcohol, and an aromatic solvent.
