New chemistry for high TAN crude corrosion control – Dorf Ketal’s TANSCIENT™
Article Type: New materials and equipment From: Anti-Corrosion Methods and Materials, Volume 62, Issue 3
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 LLC, a specialty chemical company serving the downstream refining and petrochemical industries, has introduced TANSCIENT™, a breakthrough in corrosion science. TANSCIENT™ offers more effective passivation and ongoing protection with up to 80 per cent 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 March 15-19, 2015 in Dallas, Texas:
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) Pvt. Ltd.
High phosphorus treat rates with traditional phosphate ester programs may impair the downstream unit catalyst increasing fresh catalyst addition and may potentially foul the hydrotreater, decreasing the run length of the unit. TANSCIENT™ avoids this risk.
“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.
