Catalyst poison removal
The single most important factor for hydroprocessing unit profitability is the length of time your catalyst remains active. No matter how high a catalyst’s start-of-run activity is, if it deactivates more rapidly than expected, your unit performance will suffer and profits will drop.
A major cause of premature catalyst deactivation is impurities in feedstocks. Nickel, vanadium, iron, silicon, arsenic, phosphorus, and sodium are often present in feedstocks at ppb or even ppm levels, and the effect on downstream catalysts can be devastating.
Our expertise in contamination control, our market-leading poison guard catalysts, and our proven grading strategies minimize the effect of impurities in your feed blend and maximize profitability at your refinery.
