CO2eq by 690 000 tpy at Hengli’s nitric acid plant in China

One of the winners of the campaign is Hengli which operates a 300 000 tpy nitric acid plant in Dalian, China. With the successful installation of the catalyst in June 2024, the plant is projected to reduce its N₂O emissions by 690 000 tpy of CO₂eq.

Xaver Karsunke, Vice President of Specialty Catalysts at Clariant, said: "We are honored to support Hengli Petrochemical in their drive toward cleaner chemical production. Our catalysts not only help companies, like Hengli, to significantly reduce harmful greenhouse gas emissions, but also to do so in the most efficient and economical manner possible. Partnerships like this are crucial for accelerating China’s energy transition and meeting the country’s ambitious decarbonisation goals.”

Aibo Zhu, Plant Manager at Hengli Petrochemical, stated, “We are committed to sustainable and environmentally responsible operations across all our businesses. We are proud to partner with Clariant on this N₂O abatement solution to significantly reduce greenhouse gas emissions at our large-scale nitric acid facility in Dalian.” Based in Dalian, China, Hengli Petrochemical Co. Ltd is an integrated petrochemicals producer. The company is part of the Hengli Group, an international conglomerate focused on oil refining, petrochemicals, advanced polyester materials, and textiles. Commonly known as laughing gas, nitric acid is essential for manufacturing fertilizers. However, its production emits N₂O, which is almost 300 times more harmful to the climate than CO₂. The problem is further compounded by the fact that more than half of nitric acid producers do not remove N₂O from their off gas. Based on 66 million tpy of nitric acid produced around the world, N₂O emissions equal to more than 100 million tpy of CO₂eq. With the catalyst technology, N₂O and other nitrogen oxides can be removed almost completely (up to 99% for tertiary abatement and 95% for secondary abatement). Designed as a drop-in solution, the catalysts can be easily installed in any state-of-the-art nitric acid plant without disrupting the manufacturing process.
