MOSCOW (MRC) -- Clariant, a focused, sustainable and innovative specialty chemical company, has launched a major global campaign to reduce the climate change impact of nitrous oxide (N2O), according to Hydrocarbonprocessing.
Drawing on decades of catalyst research expertise, the company has developed the EnviCat N2O-S catalyst, which is proven to remove up to 95% of N2O generated as a by-product of nitric acid production.
Clariant is now offering a free fill of EnviCat N2O-S to 10 nitric acid producers who do not have N2O off-gas treatment in place. Through the campaign, the company intends to help avoid greenhouse gas emissions equivalent to several MM tons of CO2 per year.
Of the approximately 500 nitric acid plants operating globally, more than half run without N2O abatement, mostly in regions without applicable emission control regulations. Clariant now aims to tip the balance towards more sustainable production processes. The company is offering a free first fill of EnviCat N2O-S catalyst to up to 10 nitric acid producers who currently do not use an N2O abatement catalyst.
Hans Bohnen, Chief Operating Officer at Clariant, commented, “Sustainability is no longer an afterthought of business; it is central to what we do and requires action now. That’s why we announced new ambitious science-based climate targets for Clariant. But as a specialty chemicals company we can do more: I am therefore particularly proud to announce that we have committed a substantial investment to help nitric acid producers worldwide virtually eliminate their N2O off-gas emissions. This benefits the climate, while also helping the nitric acid manufacturers to minimize their carbon footprint and progress on their sustainability journey.”
Clariant’s EnviCat N2O-S catalyst converts up to 95% of the N2O formed during nitric acid production into the harmless substances oxygen and nitrogen. Besides climate benefits, the catalyst can also slightly increase nitric acid yield by improving the efficiency of the ammonia oxidation process. Designed as a convenient “drop-in” solution, the catalyst is easy to install with almost no engineering modifications.
As MRC reported earlier, in October 2020, Clariant announced the construction of a new state-of-the-art catalyst production site in China. This project represents a significant investment which further strengthens Clariant’s position in China and enhances its ability to support its customers in the country’s thriving petrochemicals industry.
The new facility will be primarily responsible for producing the Catofin catalyst for propane dehydrogenation, which is used in the production of olefins such as propylene. Thanks to its excellent reliability and productivity, Catofin delivers superior annual production output compared to alternative technologies, resulting in increased overall profitability for propylene producers, says the company. Construction at the Dushan Port Economic Development Zone in Jiaxing, Zhejiang Province was scheduled to commence in Q3 2020, and Clariant expects to be at full production capacity by 2022.
Propylene is the main feedstock for the production of polypropylene (PP).
According to MRC's ScanPlast report, PP shipments to the Russian market were 1,138,510 tonnes in January-September 2021, up by 30% year on year. Supply of propylene homopolymer (homopolymer PP) and block-copolymers of propylene (PP block copolymers) increased, whereas supply of injection moulding statistical copolymers of propylene (PP random copolymers) decreased significantly.
Clariant AG is a Swiss chemical company and a world leader in the production of specialty chemicals for the textile, printing, mining and metallurgical industries. It is engaged in processing crude oil products in pigments, plastics and paints.
