Lowering sulphur levels in finished fuels is a common practice going back to the 1990s, in an effort to reduce greenhouse gas emissions and improve air quality. With the introduction of new hydroprocessing technologies, Refineries have always been able to adapt to these new standards. However, new regulation changes pose new challenges for the industry.
With global regulations becoming increasingly more stringent, refineries are being forced to run their assets under more severe conditions to meet these new vehicle and environmental standards, increasing unit 'stress', causing the industry to experience more widespread fouling issues.
"Upgraded antifoulant technology is helping refiners overcome the increased hydrotreater fouling issues that result from more stringent fuel sulphur limits."
Nalco Water has developed innovative antifoulant chemistries designed to help refineries effectively mitigate the higher fouling impact on hydrotreating units due to current and pending regulation changes. The benefits from implementing the new Nalco Water antifoulant programme show significant improvements in extending unit run length, reduced pressure drop, and increased throughput.
Read the full article in PTQ magazine covering two recent case studies that detail the positive impact of the new Nalco Champion antifoulant innovations designed to help refineries address their fouling concerns, lower maintenance and energy costs, and maintain unit availability targets.
