This paper studies the characteristics of SO 2 emission and NO x emission during the combustion of petroleum coke and desulfuration processes and discusses the effect of limestone on NO x emission. Considering desulfuration, denitration and operating costs of boilers, there is an appropriate Ca/S mole ratio for the combustion and desulfuration of petroleum coke. It provides a practical basis for industrial utilization of petroleum coke.展开更多
文摘Petroleum coke has high nitrogen and high sulfur.Its combustion will cause pollution to atmosphere. This paper studies the characteristics of SO 2 emission and NO x emission during the combustion of petroleum coke and desulfuration processes and discusses the effect of limestone on NO x emission. Considering desulfuration, denitration and operating costs of boilers, there is an appropriate Ca/S mole ratio for the combustion and desulfuration of petroleum coke.
