Lighter ethylene cracking feeds lead to increased fouling problems. Gas crackers specifically face fouling issues due to the low volume of heavier aromatic fluids formed during cracking. Furthermore, increased ethylene production from ethane results in fewer internal heavy streams available for use as a wash oil. Heavy aromatic fluids have a proven track record as effective compressor wash oils but have at times faced supply and availability challenges.
ExxonMobil Chemical has a solution to meet your needs: Exx-Wash, a newly developed portfolio of tailored wash oils.
Exx-Wash process oil is specifically designed to deliver an array of benefits for olefins manufacturers:
