New Reds - Pigment Innovation

摘要

Red is the most important iron oxide pigment by volume with global consumption of over 400,000 tons per year. There are three major production routes for iron oxide red, each with its own individual challenges with regard to sustainability. The most commonly used Penniman process is under continual environmental scrutiny in China. Innovative process optimization will enable LANXESS to reduce Penniman red energy demand significantly. LANXESS's new Penniman Red process will be the first with exhaustive waste gas treatment, including laughing gas decomposition. Due to the high energy efficiency and the exhaustive waste gas treatment, the emission of climate relevant carbon dioxide equivalents will be reduced by nearly 90%. Additionally, a new generation of previously unavailable clean, yellow-shade reds have been developed offering interesting new opportunities to the coatings industry.
