For petroleum refiners, improving profitability by processing high acid opportunity crudes requires an investment in high temperature corrosion protection. Investing in metallurgy delays profit improvement and return on capital is uncertain. Conventional chemical inhibitors require high phosphorus treat rates, which introduce fouling and operating risks that have deterred acceptance of chemical solutions.
In response, Dorf Ketal Chemicals, a specialty chemical company serving the downstream refining and petrochemical industries, has introduced TANSCIENT™. TANSCIENT offers more effective passivation and ongoing protection with up to 80% less phosphorus than competitor HTCI products. TANSCIENT was previewed recently at the CORCON 2014 Conference & Expo in Mumbai, India, and will be launched at CORROSION 2015 to be held in Dallas, Texas from 15 to 19 March 2015.
“TANSCIENT™ is effective at concentrations significantly below the recommended phosphorus specification of the Canadian Crude Producers Association, 0.5 ppm P, a limit that has been reinforced by catalyst manufacturers”, said P.N. Ramaswamy, Director, Technical Services at Dorf Ketal Chemicals (I). “Refiner confidence in this new technology is changing perspectives on the use of chemistry”, said Jim Ondyak, executive vice president of Dorf Ketal. “The improved level of safety, reliability, efficiency and cleanliness in corrosion protection offered with this chemistry is changing operating strategies for taking advantage of high TAN opportunity crudes.”
