EnviNOx cuts N2O emissions at CSBP nitric acid plants

thyssenkrupp Uhde has delivered its patented EnviNOx® technology to CSBP’s newest nitric acid plant at Kwinana in Western Australia, achieving more than 98% reduction of nitrous oxide (N₂O) emissions and outlet concentrations below 1 ppmv. CSBP – part of Wesfarmers Chemicals, Energy & Fertilisers (WesCEF) – has now signed a further contract for EnviNOx® systems on its NAAN1 and NAAN2 nitric acid plants, meaning all three facilities (NAAN1, NAAN2 and NAAN3) will be integrated with the technology using thyssenkrupp Uhde’s improved EnviNOx® catalyst manufactured by partner BASF.
