Wash Oil is applied to control the build up of polymers on cracked gas compressor turbines, seals, intercoolers, and heat exchangers, wash oils are typically injected into ethylene crackers on a continuous basis or on regular intervals. Wash oil has a fairly high initial boiling point (>150 Deg C) so that it won’t immediately flash to vapor, combined with a high aromatics content (>90%) for dissolving polymeric compounds.
