EnviCat - Purification of Industrial Gases
Clariant’s EnviCat catalysts and Actisorb adsorbents address the high quality demands of technical gases, reducing the level of substances such as hydrocarbons, hydrogen, oxygen, carbon monoxide or sulphur compounds to minimal levels of a few ppm or even ppb. Building on decades of research and practical application, Clariant has developed products providing mechanical stability and durability to ensure efficient and reliable purification of technical gases.
Following the steam reforming process to produce hydrogen from a hydrocarbon stream, CO2 is separated using pressure swing adsorption (PSA) or gas scrubbing. This CO2 must be purified – removing such impurities as H2, hydrocarbons, and CO before it is reused for the urea synthesis process. EnviCat® catalysts remove trace impurities to achieve the necessary purity.
Products:
- EnviCat OXO to remove hydrogen
- EnviCat HC to oxidize hydrocarbons and carbon monoxide
Ethanol and CO2 are produced by fermenting the sugar and starch components of plant-based materials. After separating the CO2 with the aid of a thermal separation process, some impurities may remain such as residual ethanol, other hydrocarbons, sulfur compounds and oxygen. These trace impurities must be removed from the CO2 before it can be used for food-grade applications, such as the beverage industry.
Products:
- EnviCat HC to oxidize methane, ethane and other hydrocarbons
- ActiSorb to remove sulphur
High-purity oxygen is required for various chemical processes. Any traces of hydrogen remaining as a result of electrolysis must therefore be reliably removed.
