DuPont Clean Technologies Brings New MECS® Catalysts to the Market

Two new MECS® catalyst products provide improved emissions & capacity performance.

WILMINGTON, DEL. (PRWEB) NOVEMBER 05, 2020 - DuPont Clean Technologies introduces two new sulfuric acid catalysts: MECS® Super GEAR™ and MECS® XLP-310 which build upon its well-proven GEAR® and XLP catalyst product lines. While both products will benefit new or existing plants, Super GEAR™ was specifically developed to minimize total installed cost and achieve world class emissions levels in new plants, while XLP-310 was developed to provide existing plants with an economical option to reduce emissions and boost capacity.

Since its introduction to the sulfuric acid industry in 2011, MECS® GEAR® catalysts (which have a Geometrically optimized hexa-lobe shape that Enhances surface area and Activity while Reducing pressure drop build-up over time) have proven to maximize conversion, reduce emissions, and increase the time between turnarounds. Super GEAR™ combines the GEAR® shape with an advanced formulation, resulting in a truly unique and best-in-class sulfuric acid catalyst which offers sulfuric acid plants the benefits of GEAR® catalyst while further minimizing the total installed cost of new converters.

MECS® XLP ribbed ring catalyst has been in use since 2003 throughout the sulfuric acid industry and is proven to be a reliable and economical choice for all converter passes. XLP-310 adds to the versatility of the XLP product line by incorporating an advanced formulation with the XLP shape, resulting in the most active XLP ribbed ring product ever made. XLP-310 will provide the greatest value when installed in converter passes not limited by equilibrium. This targeted approach will allow plants to reach their conversion goals without the need for expensive plant modifications or complete catalyst replacement in every pass of the converter.    

Eli Ben-Shoshan, Global Business Leader, DuPont Clean Technologies, said, “Our goal with the development of the two new MECS® catalyst product lines is to help acid plant operators increase conversion and improve environmental performance with minimal investment. As such, we are pleased to announce that field installations have shown both MECS® Super GEAR™ and MECS® XLP-310 catalysts can achieve considerable increases in conversion rate, even when only installed in part of a converter. DuPont Clean Technologies will continue to look for ways to bring value to our customers by leveraging our position as a world leader in sulfuric acid process technologies, our nearly 100 years of experience in catalyst production, and by focusing on those aspects that matter most to our customers.”

Tom Brouwers of DuPont Clean Technologies will speak to these highly effective catalyst offerings next week at the CRU Sulphur + Sulphuric Acid 2020 virtual conference. Look for the presentation entitled “Effective emissions management and reduction in sulphuric acid plants with the help of advanced catalyst types” in the Sulphuric Acid Track of this event on Wednesday, November 11, 2020 at 17:20 CET.
