Honeywell announced that its Callidus® low-nitrogen oxides (NOx) burner technology has been selected by Sinopec Beijing Yanshan Petrochemical Co. Ltd. (Yanshan) to help meet China's new NOx emission regulations. More than 400 burners used in Yanshan's ethylene process units have been revamped and achieved reductions of 40% to 50% of NOx emissions from ethylene furnaces. In addition, Honeywell UOP is providing these process units with engineering, performance verification testing, burner fabrication and service. Under new government standards in China, emissions of nitrogen oxides from industry furnaces are required to drop from 150 to less than 100 milligrams per cubic meter this year. These pollutants are the primary cause of acid rain and increased surface ozone concentration, which have serious and direct impacts on public health and the environment. Among the technologies Honeywell UOP developed to meet new emissions standards are high-performance low-NOx Callidus process burners. These burners are designed to meet NOx reduction requirements for fired heaters in refinery and petrochemical plants, where space is limited and temperatures typically reach 1,200 degrees Celsius. Callidus burners can be customized to meet requirements of all types of applications, including refinery heaters, reformers, ethylene crackers, coker units, and CCR (continuous catalytic reforming) and propane dehydrogenation process heaters.
