METAL SILICATE AND ORGANIC DEPOSIT INHIBITOR/DISPERSANT FOR THERMAL RECOVERY OPERATIONS OF HYDROCARBON FUELS

摘要

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.
