  • The fuel gas system at a large Midwestern refinery had experienced numerous problems with leakage and fouling with sludge. A team of reliability experts determined that water in the fuel gas system was the primary cause of corrosion and sludge formation. A Glycol Dehydration Unit (GDU) was installed to treat the plant's fuel gas supply in order to improve the reliability and integrity of the existing fuel gas system.
