Let’s protect the climate

Protecting the climate can only be successful if we all work together. Therefore, Clariant now offers a free first load of our highly effective nitrous oxide abatement catalysts to up to 10 nitric acid producers.

• 10 producers receive a fill of EnviCat N₂O-S catalyst – for free
• Offer is open to nitric acid producers who do not yet use an N₂O abatement catalyst

Nitric acid – A chemical feeding the world

Nitric acid (HNO₃) is an important chemical for the preparation of fertilizers. But its production causes significant emissions of nitrous oxide (N₂O). Also known as “laughing gas”, N₂O is extremely harmful to the climate.

N₂O – A potent climate gas

Unfortunately, more than half of the world’s nitric acid plants run without N₂O offgas reduction.^*1 Every year, the N₂O emissions from nitric acid production represent about 100 million tons of CO₂.*²

EnviCat^® N₂O-S – THE POWERFUL, PROVEN N₂O REMOVAL CATALYST

The removal of N₂O off-gas is safe and simple: Clariant’s EnviCat N₂O-S catalyst almost completely removes nitrous oxide and converts it into harmless oxygen and nitrogen.

• Removes up to 95% of N₂O formed during nitric acid production^*3
• Secondary abatement catalyst installed directly (in second position) after ammonia oxidation reactor
• Robust design ensures high mechanical strength Easy to install “drop-in” solution

Experienced engineering partners – worldwide

As a “drop-in” catalyst, EnviCat^® N₂O-S usually requires little if any engineering changes. If a nitric acid production facility should still wish to receive engineering support, Clariant’s highly experienced global partners can help.

Take Action – in three easy steps

1. Interested nitric acid producers may apply until 31 March 2022 via this website.
2. Out of all valid applications, an independent attorney will draw 10 nitric acid producers* who will receive a free catalyst load.*
3. Clariant will inform the winning applications in May 2022. The catalyst supply will be aligned with the winning applicants.

Don’t miss this unique opportunity to protect the climate

Complete our application form now to be one of 10 nitric acid producers worldwide to receive a free first load of Clariant’s EnviCat N₂O-S catalyst.

^*Clariant offers one free catalyst fill for one nitric acid production unit per group of companies. Clariant’s terms and conditions of sale apply. Clariant’s acceptance of an application is subject to competition law compliance and technical feasibility reviews, and in the sole discretion of Clariant. The free fills are assigned via a drawing, without any legal obligations and without legal recourse, and are subject to compliance with locally applicable laws and regulations.
