Case Study: Contamination Clean-up

The facility had experienced several documented process leaks of lignin into their cooling water system due to failed check valves as well as some operating errors. Over time it was determined that lignin had coated the entire system and was slowly sloughing off and causing plugging in the surface condenser which lowered the operating vacuum of the system by as much as 20%. This was causing a major decrease in operating efficiency and having a huge impact on the cost of operating the system.
