Clariant’s EnviCat® VOC catalyst: the efficient solution for clean energy and air
Munich, July 13, 2017 – Clariant, a world leader in specialty chemicals, is among the foremost suppliers of catalysts for off-gas purification. The company combines high-performance EnviCat catalysts with 40 years of global expertise in catalytic air and gas purification to offer highly effective solutions for the market. Based on the technique of catalytic oxidation, EnviCat VOC effectively removes harmful volatile organic compounds (VOCs) and carbon monoxide while reducing the energy consumption of thermal units by up to 40%. The catalyst is suitable for numerous industries that emit VOCs, such as the chemicals, food, printing, and energy production sectors.
With the growing focus on air purification, regulations regarding VOC limits are becoming increasingly stringent, both nationally and internationally. This is especially true in larger, high-growth economies like China. Conventionally, off-gas is treated by recuperative thermal oxidization (RTO). However, compared to catalytic oxidation, RTO occupies far more plant capacity, and requires substantially higher reaction temperatures, making it more expensive and less safe. Moreover, while RTO is adequate for meeting current regulations, its efficiency for future, stricter policies is uncertain.
In contrast, EnviCat VOC offers a high conversion efficiency of more than 99%, yet it operates at up to 400°C lower temperatures. This reduces fuel consumption and stress on equipment, resulting in significant economic, operational and safety advantages for producers. Thanks to the catalyst’s adaptable design, and Clariant’s advanced manufacturing capabilities, EnviCat VOC can be customized according to operators’ processes and requirements to ensure optimum efficiency. This flexibility also means that EnviCat VOC has the potential to fulfill both current and future emissions standards. Numerous production facilities around the world already benefit from the high conversion and cost efficiencies of EnviCat VOC.
Stefan Heuser, Senior Vice President & General Manager Business Unit Catalysts at Clariant, explained the company’s comprehensive customization concept, saying, “With EnviCat VOC, high efficiency is truly tailor-made. We work closely with our customers and engineering partners to deliver the optimum, one-stop solution in every case. Our versatility and innovation has made Clariant one of the market leaders in off-gas purification.”
Shanghai Donghua Environmental Engineering Co. has been one of Clariant’s key partners in China for almost 15 years. Mr. Zhao Xiaoping, the General Manager at Shanghai Donghua, described the relationship, stating, “Both our companies and customers benefit from our collaboration. EnviCat VOC is a perfect fit for our technology. We have used the catalyst in numerous off-gas treatment facilities, such as acrylic acid and acrylonitrile plants, with great results.”
EnviCat® IS A TRADEMARK OF CLARIANT REGISTERED IN MANY COUNTRIES.
