CHEMAOIL WASH OILS
Wash oils which are designed with high aromatic contents are injected into ethylene crackers on a continuous basis or on regular intervals as an efficient anti fouling agent. Wash oils have a fairly high initial boiling point so that they won’t immediately flash to vapor. The typical fouling agents are polymers, aromatics and other products like cyclic dienes and oxygenates.
APPLICATIONS
1.
It controls the build-up of polymers on cracked gas compressor turbines, seals, intercoolers, and heat exchangers.
2.
It cleans efficiently these equipment due to strong solvency
3.
They minimize corrosion and fouling
