Residuum Oil Fouling Inhibitor


This fouling Inhibitor is a very effective agent to keep the residuum oil system from forming scale, it also has certain effect in cleaning scale already existed in the system.  It is suitable for residuum oil pipeline, heat exchanger coking and incrustation, and can improve the efficiency of the heat exchanger to allow stable operation of the system, it can also prolong the operation cycle of the system and reduce system shut downs. 


1.The product has good dispersivity, it can effectively avoid accumulation of catalytic agent powder, corrosion products and salt, etc., suspended in the residuum oil, and therefore control the increase of particle in the residuum oil and deposition.

2.It has anti-oxidizing property, it can form inertia molecule with the oxidized free hydroxyl group and can stop polymerization caused by oxygen. 

3.It has metal passivation property, and corrosion resistant property and surface modification feature.
