| Abstract: |
| The treatment of oily sludge using drying technology has become the research focus in petrochemical industry.This paper introduced briefly the source of the oily sludge,and then the drying curves as well as drying rate curves were obtained by drying experiments of oily sludge.The methods of time computation in drying under this condition with mass transfer equations are described.The experimental data of drying kinetics for oily sludge were treated with drying models and thermal analysis kinetics method.The drying equation got by comparison is in accord with Page equation. |
| Key words: oily sludge drying time drying kinetics |
