Engineering Application Practice of Rotary Pyrolysis Desorption Technology for Oil Based Cuttings
In an oil-based cuttings resource utilization project in Sichuan,continuous rotary pyrolysis desorption technology was used to treat waste oil-based mud and cuttings,and the content of petroleum hydrocarbons in the remaining solid phase was less than 4500 mg/kg,which replaced some raw materials for cement,and the comprehensive oil recovery rate was more than 99%.The application practice proves that the rotary pyrolysis desorption technology is a technology for the resource utilization of oil-based cuttings with stable equipment operation,significant environmental benefits and considerable economic benefits.At the same time,some problems existing in application practice are analyzed and suggestions are given.
