Chemical

Sulzer Mixers are used for a wide range of mixing duties in the Chemical Process industry. The applications range from mixing of liquids of various viscosities, mixing including reaction, gas liquid contacting/ mass transfer and absorption, gas mixing and liquid evaporation in order to cope with corrosive chemicals the mixers are available in a wide range of materials.

Nitric acid is obtained by ammonia conversion in two steps. In the first step ammonia is oxidized to nitric oxide with the air oxygen in the presence of a platinum catalyst. The static mixer SMV™ secures a homogeneous mixture between ammonia and air to provide the optimal operating conditions for the catalyst bed.
