Modeling and mass and energy balance analysis of oily sludge pyrolysis process
The steel industry produces a lot of oily sludge when cooling steel,which causes serious pollution to the environment.Experimental investigation and simulated analysis were conducted on the pyrolysis process of oil sludge,and a compositional analysis was performed on the pyrolysis oil separated during the experiment.Within the light oil fraction,aliphatic compounds,heterocyclic compounds and aromatic compounds account for 97.8％,1.85％,and 0.35％,respectively.As for the heavy oil fraction,aliphatic compounds and heterocyclic compounds make up 93.27％and 6.73％,respectively.Additionally,the model was established by Aspen Plus,and the mass and energy balance was analyzed according to the model data.The results showed that the energy carried by pyrolysis products is pyrolysis oil,residue,pyrolysis gas and water in descending order.The volatile matter produced by oily sludge accounts for 69.4％,which indicates that there are more chemical energy that can be effectively utilized.
