Opportunity feed sources have extended the range of poisons that hydroprocessing unit operators must face. Many of the contaminants can cause severe catalyst poisoning, even at very low concentrations. Catalyst contamination negatively impacts your return on investment, which is why Criterion Catalysts & Technologies (Criterion) has committed unique R&D resources to solve the contaminant problems you face every day.
Criterion offers SENTRY™ Guard Catalysts and Support — an entire portfolio of products dedicated to protecting hydroprocessing operations from feedstock contaminants. SENTRY(TM) offers prevention, diagnosis and resolution of contamination issues — protecting your catalyst investment and, ultimately, your bottom line.
