Hengli Petrochemical (Dalian) Refinery Co., Ltd. will use Callidus advanced flares and low-nitrogen oxides (NOx) burner technology at its refinery and petrochemicals complex in China.
Honeywell will provide the largest flare system in Asia, with a capability of 5000 t/hr. In addition, the company will provide more than 1400 Callidus® low-NOx burners to provide heat for refinery processes, as well as process design and procurement services, key mechanical equipment and instrumentation.
Under the Chinese government’s Emission Standard of Pollutants for the Petroleum Refining Industry, emissions of nitrogen oxides from industry furnaces are required to drop 33%, from 150 milligrams per cubic metre in 2015 to less than 100 this year. These pollutants are a primary cause of acid rain and increased surface ozone concentration, which have serious and direct impacts on public health and the environment.
The Callidus low-NOx burner technology and customised burners will allow Hengli Petrochemical to reduce NOx emissions to half the limit prescribed under China’s new emission control regulation. The burners can be customised to meet the requirements of all types of applications at Hengli, including refinery heaters, reformers, ethylene crackers, and CCR (continuous catalytic reforming) and propane dehydrogenation process heaters.
“Callidus’ advanced burner technology helps refineries and petrochemical plants reduce NOx emissions, better control carbon monoxide emissions and achieve higher fuel efficiency, while our low-VOC flare technology provides excellent combustion performance,” said Henry Liu, vice president and general manager of Honeywell UOP China. “These technologies offer excellent economics and will help Hengli comply with stricter environmental regulations in China.”
