Abstract
Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.
