Everything from a single source - Successful project business in equipping a catalytic world-scale hydrogenation plant.
2,244 INTEC ball valves for the production of hexamethylene diamine (HMD) and polyamide 6.6.
Hexamethylene diamine (HMD) is a precursor and forms the basis for the production of high-quality polyamide 6.6 plastics and coating raw materials. These products are used, for example, in the automotive industry (e.g. airbags) and for the production of specialty fibers (e.g. nylon).
In the manufacturing process, adiponitrile (ADN) is hydrogenated. Adiponitrile and hydrogen are converted into hexamethylenediamine with the aid of the Raney nickel catalyst. The hydrogenation (hydrogen loading) takes place catalytically usually at a pressure between 30 bar and 50 bar and in the temperature range between 200°C and 250°C.
For use along the entire manufacturing process with a wide range of operating conditions, the customer required high-quality chemical ball valves to ensure safe plant operation as well as the necessary quality of the end-product.
