Emission of nitrogen/sulfur pollutants and migration of heavy metals during combustion of oily sludge from the oil refining process in fluidized bed
G Wan, L Sun, L Xu, L Lin - Journal of the Energy Institute, 2024 - Elsevier
Oily sludge is a kind of hazardous waste due to the enrichment of nitrogen, sulfur, and heavy
metals. In this work, the combustion of oily sludge from an oil refining factory in a fluidized
bed reactor at 850–1050° C and 0.8–1.2 excess air ratios were studied, with a focus on
emission of nitrogen and sulfur pollutants and migration of Cr, Ni, Cu, Zn, Cd, Pb. The
emission characteristics of nitrogen and sulfur pollutants were exhibited through monitoring
the flue gas. The migration characteristics of heavy metals were clarified by analyzing their …
