Utilization Status of Pyrolytic Residues in Oily Sludge Disposal Projects
The residue from pyrolysis of oily sludge is not only a large amount,but also stipulated as hazardous waste,which seriously restricts the promotion of pyrolysis technology and the utilization of residue.At present,the research and exploration of the multi-purpose utilization of pyrolysis residue as desorbents,catalysts,flocculants,subgrade material have been carried out,and the industrial application has not been realized.The large-scale way to utilize the residue is limited to in the oilfield area as materials padding and paving well sites and roads.Therefore,based on the industrialization and research of oily sludge pyrolysis.The research summarized the main ways and current situation of resource utilization of oily sludge pyrolysis residue in projects,analyzes the difficulties and risks encountered in the utilization of residue at present,looks forward to the trend of diversified resource utilization according to local conditions,and puts forward research recommendations.
