MOSCOW (MRC) -- Honeywell has recently announced that Hengli Petrochemical Co. Ltd. successfully used Callidus burner technology from Honeywell UOP to minimize nitrogen oxide (NOx) and carbon monoxide (CO) emissions in China, and reduce the impact of these emissions while ensuring safe and stable operations, according to Hydrocarbonprocessing.
Hengli selected Callidus advanced flares and low-NOx burner technology in 2017 to comply with environmental regulations and improve energy efficiency and operational safety at its refinery and petrochemicals complex in Dalian, Liaoning Province. Equipped with innovative low fire mode (LFM) technology, Callidus burners reduced Hengli’s emissions, improving air quality and helping to eliminate causes of acid rain.
When furnace temperatures are below 650 C, the NOx burner produces higher levels of CO. But by using the LFM technology, the Callidus burners kept emissions at ideal levels - with NOx and CO each less than 50mg/Nm3. This helped Hengli solve an industry problem of minimizing both NOx and CO emissions to reduce environmental impact, while ensuring safe and stable operations.
“We selected the Callidus technology because it’s the global leader in combustion technologies and because it was the first in China to solve the CO emission issue in a NOx burner,” said Liang Peng, Static Equipment Director, Hengli Petrochemical. “Callidus burners also can be replaced without requiring a shutdown of the furnace and other operations.”
“Our experience with these technologies around the globe helps customers like Hengli generate economic value by improving their return on investment with environmentally sound products,” said Xiang Lei, vice president and general manager, Honeywell UOP China. “We’re pleased to work with Hengli to improve its energy efficiency and operational safety.”
As MRC reported earlier, in November, 2020, Honeywell announced Zhenhua Petrochemical Co. Ltd will use Honeywell UOP’s C3 Oleflex technology for propane dehydrogenation to process 1 million metric tons per year of polymer-grade propylene for a proposed plant in Dongying City, Shandong Province, China.
Propylene is the main feedstock for production of polypropylene (PP).
According to MRC's ScanPlast report, PP shipments to the Russian market reached 141,870 tonnes in January 2021 versus 123,520 tonnes a year earlier. Supply of homopolymer PP and PP block copolymers increased.
