The control of sulfur oxide (SOx) emissions keeps being a crucial issue for refineries when it comes to secure market competitiveness. The use of additives for SOx emission reduction of FCC units is a reliable and economical strategy that aids refiners in meeting progressively more stringent environmental regulations while aiming at maximizing unit profitability by processing more challenging, high sulfur content feeds.
The DuraSOx additive results from an intense development work focused on the preparation of additives for SOx reduction having the highest attrition resistance of the market without compromising performance. The additive is recommended for FCC units operating under total combustion regimen and that are sensible to particulate matter losses.
A new binding process is the key behind the DuraSOx success, providing better attrition resistance and enabling more active sites to be incorporated into each additive particle, resulting in more efficiency in SOx removal for the same additive amount and minimum dilution of the catalyst inventory.
