Bayer has been commissioned by Berzelius, to build a sulfuric acid plant operating on the BAYQIK process. The plant has now been successfully brought on stream after just 17 months.
The BAYQIK (Quasi-Isotherme-Katalyse [quasi-isothermal catalysis]) process developed by BTS can increase the SO2 inlet concentration by up to 50 percent by volume. Coupled with optimized process management, results in significantly higher conversion, i.e. sulfur dioxide emissions are greatly reduced. Another benefit is an increase of at least 30% in available plant capacity, said the company.
Berzelius tested and optimized the process in a pilot application on-site. Its robustness, quality and cost benefits were the deciding factors in awarding the contract for the planning, delivery and construction of the first large-scale plant. The facility has a total capacity of 450 metric tons of sulfuric acid per day.
