KVT offers a wet process technology for the production of sulfuric acid from various types of off-gases, spent acid or sulfur bruning. Our desulphurization technologies offer the possibility to clean industrial off-gases under the aspect of sulfuric acid recovery. Developed by Kanzler Verfahrenstechnik GmbH. (KVT), the first plant was in operation for a viscose production company in 1992. During the last 20 years, OXYSULF has found applications in large fields of business. KVT offers different OXYSULF solutions for a wide range of gas concentrations and compositions. KVT can deliver a turn-key plant or provide engineering, key equipment and catalysts that are unique for performance, stability and durability. The process is based on the catalytic or the combination of thermal and catalytic oxidation of sulfur–bearing compounds and formation of sulfuric acid. It is able to handle contaminants such as SO2, H2S, COS or CS2 at a wide concentration range. OXYSULF technologies are applicable in the following markets: - Refineries & Petro-chemical Industry (SRU) - Coal based Fertilizer and Chemical Industry (Syngas SRU) - Cokes Manufacturing - Non-Ferro Metallurgical Industry (Mo, Pb…) - Power Industry - Viscose Industry - Natural Gas Processing
