Methods for providing prophylactic surface treatment for fluid processing systems and components thereof

摘要

The invention relates to a method for creating a diffused thin film surface treatments on one or more interior surfaces of closed or partially closed fluid transport or processing systems providing improved surface prophylaxis against fouling. The method involves contacting the interior surfaces to be treated with a metal compound composition, and converting the metal compound composition to metal oxide for example by heating the surfaces to the desired temperature after all or a part of the system has been assembled. Embodiments of the present invention can be performed in situ on existing fluid processing or transport systems, which minimizes the disruption to the surface treatment created by welds, joints, flanges, and damage caused by or during the system assembly process.

1. A method for decreasing or preventing fouling on an interior surface of a pipe or tube of a fluid processing or transport system, comprising:
applying at least one metal compound composition to the interior surface with a pig train, wherein the at least one metal compound composition comprises
silicon 2-ethylhexanoate,sodium 2-ethylhexanoate,calcium 2-ethylhexanoate,chromium 2-ethylhexanoate, and2-ethylhexanoic acid; and exposing the surface with the applied at least one metal compound composition to an environment that will convert at least some of the silicon 2-ethylhexanoate, at least some of the sodium 2-ethylhexanoate, at least some of the calcium 2-ethylhexanoate, and at least some of the chromium 2-ethylhexanoate to at least one metal oxide; wherein the at least one metal oxide is resistant to fouling.
