The invention provides a tar residue resource treatment process, which takes emulsification dehydration, solvent extraction and centrifugal separation as the core, uses coal tar 200-230°C distillate oil as the main extraction agent, and adds a small amount of crude benzene and industrial naphthalene to form Composite extraction agent, the proportion of each component is: Coal tar 200-230℃ distillate 90-95wt / %, crude benzene 4.1-9.7wt / %, industrial naphthalene 0.3-0.9wt / %, the demulsification and dehydration temperature is 35 ‑55°C, extraction temperature 55‑60°C, pressure 101.325kPa, pump circulation flow 15‑20m3 / h, extraction time 3‑4h, centrifuge speed 2500‑3000r / min, etc., using a combination of thermal extraction and centrifugation The process enables the recovery rate of tar in the tar residue to reach more than 95%. In terms of raw material adaptability, the present invention has been verified to be very suitable for raw material tar residue with a moisture content of 20-60%. The extraction agent used is used to complete the oil-water process. The slag does not need to be recycled after separation. It is directly stored and utilized in the oil as an oil product component without recycling. It simplifies the separation process, avoids waste and saves energy. It effectively solves the problems of energy utilization and environmental protection treatment of tar residue.
