Studies on Molecular Distillation Disposal of Petrochemical Hazardous Wastes

In this paper, heavy residual oil and distillation residues of hazardous wastes are researched with molecular distillation separation reduction technology. The separation experiments were conducted at the condition of pressure of 15 Pa and the temperature of 260°C. Under the conditions, more than 20% heavy fractions can be recycled which can be the catalytic cracking raw material sources. The properties of residual oil, such as viscosity, density, carbon residue, sulphur content and other technical indicators are also analysed. There are very practical significance of molecular distillation technology in the recovery of high boiling point organic waste.
