According to the characteristics of quench oil and coke powder, an experimental setup is designed with a hydrocyclone for a pilot test. The relationships between structure size, flow rate, pressure drop, and separation efficiency are evaluated. The separation is successful in stable, long-period operations without complications. The stability of the separation significantly helps decrease covert damage to equipment such as fractionating towers, pumps, and heat-exchange facilities.
