Abstract
A method and a process to treat coke generated from a process application. The method includes the steps of recovering a mixture of coke particles and water or steam removed from at least one process application vessel. The mixture is directed to a cyclonic separator utilizing centrifugal force and gravity. Water is separated from the mixture in the cyclonic separator. Coke particles are separated from the mixture in the cyclonic separator and are directed to a thermal oxidizer. Coke particles are oxidized and gasified in the thermal oxidizer to produce gas and reduced particulate matter. The gas and reduced particulate matter are thereafter directed to a burner in the process application vessel.
