Steve has recently retired from Venator (formerly Huntsman Tioxide) where he spent 31 years in various technical and operating roles, and since 2005 as Chloride Process Technical Expert. He is technically familiar with all the key unit operations associated with TiO2 manufacture, feedstock preparations and waste handling technologies via the Chloride Process.
Key technology interests include all aspects of the Chloride Process, in particular the fluid bed chlorination of titaniferous ores, cyclone design and performance, aerosol reactor design and operation and wet bead milling of pigments.
Steve also managed company external research interests in the UK and overseas.
