Topsoe equipped three sites with state of the art sustainable Air Quality Control based on its catalytic SNOX and WSA technologies.
Carbon black manufactures around the world are looking towards the experience in the USA as, country-by-country is introducing similar stricter emission regulations, not only focusing on the stack emissions, but also a general cleaner environment with a climate-friendly and sustainable production, while at the same time ensuring cost-efficient manufacturing. As the emission and environmental regulations continue to get tighter and the manufacturing companies stive towards a higher degree of sustainability, the optimal handling of emission together with the lowest possible consumption of reagents and zero waste production are going hand-in-hand and is becoming increasingly important.
The Sustainable Air Quality Control Technology SNOXTM which removes up to 99% SO2, SO3, NOx and even oxidizes all Ammonia slip and “escaped” carbon black particulates from flue gases, even at a filter rupture, securing cleanest stack emission. The SNOXTM technology avoids any secondary pollution while recovering the sulfur from the flue gas as commercial-grade -typically 98% w/w concentrated- sulfuric acid - the world’s second most needed commodity (after oil)- mainly in demand due to its role as fertilizer in increasing the worlds food output and even production of car tires.
The extraction of energy from the flue gasses and the additional energy generated in the exothermal catalytic processes, provide a valuable thermal efficiency contribution to the carbon black manufacturing plant, keeping energy cost at a minimum and as a “side effect” the SNOXTM technology even reduces emission of the greenhouse gas carbon dioxide, compared to other more traditional technologies.
