Corrosion Inhibitor targets petroleum refiners.

Press Release Summary:

Offering effective passivation and ongoing protection with up to 80% less phosphorous than other HTCI products, TANSCIENT™ allows for safe and reliable refining of high TAN opportunity crudes. Product offers optimized thermal stability and oil solubility as well as maximum surface reactivity. With low acidity, TRANSCIENT does not require cooled slipstream for injection. Inhibitor also minimizes risk of phosphorous fouling and catalyst impairment.

New Chemistry for High TAN Crude Corrosion Control -- Dorf Ketal's TANSCIENT(TM)

HOUSTON, -- 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% 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," saidJim 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."
