SULFOX Wet Acid Process (WAP) - The Technology for cleaning up sulfurous off-gasses, with production of a saleable product as Sulfuric Acid Metallurgical Industry ? Introduction

More than 10 years ago, one of MECS?s current partners KVT developed the so called SULFOX process for cleaning waste gases containing sulfuric compounds. In this Wet Acid Process (WAP) compounds such as SO2 and H2S, CS2, COS are oxidized over catalyst bed(s) to SO3 and finally sulfuric acid is formed. The individual plants are designed according the feed gas concentrations and customers requirements to keep the investment and operating costs as low as possible. MECS strongly believes the technology we propose will meet all your expectations. Thanks to our vast experience in the construction of sulfuric acid plants (MECS built over 800 sulfuric acid plants worldwide) we were able to design you a very reliable installation. MECS is offering the metallurgical industry, besides our conventional acid plant technology (for strong SO2) and our DynaWave? scrubbing technology (for very low SO2), a SULFOX wet acid plant (for the mid range SO2 concentrations) including an optional upstream DynaWave gas cleaning plant if required. See the figure below. Besides providing advanced technology, MECS is the only company who designs and manufactures its own key critical equipment. We manufacture our own catalyst, mist eliminators, acid distributors and coolers. Because of our in-depth technology knowledge, we understand the critical aspects necessary for making optimum equipment designs. With this combined supply of technology and key critical equipment, we can make a single overall guarantee second to none other in the world.
