The invention pertains to a system and process for removing contaminants from an oil and gas well bore stream. The system comprises a vessel adapted to receive the stream from the well bore. The system also contains a centrifuge separator for breaking the emulsion of the stream, the centrifuge separator having an input for receiving the output stream from the vessel. A media filter member, which is adapted to receive the stream from the output of the centrifuge separator is also included with the system. The system further contains a carbon adsorption means, adapted to receive the output stream from the media filter, for adsorption of contaminants contained within the output stream. Also included is a level controller switch for measuring the level within the various tanks and generating a signal once a predetermined height is reached. Controller valves may also be provided, with the controller valves being operatively associated with the level controller switch for receiving the signal and opening a valve in order to release the stream to the centrifuge means. Also, the media filter further comprises a closed loop back wash line adapted to the media filter for back washing the media filter, along with a back wash tank and back wash line fluidly connecting the back wash tank to the vessel for recycling.

System and method for treating an oil gas well stream

A process and apparatus are disclosed for separating drilling mud and waste materials into pure water and a concentrated solid waste phase which is easily handled and disposed of. The process and apparatus provide for adjusting the pH of the drilling mud and waste materials to be separated, mixing the thus pH adjusted mud and waste materials with a flocculating agent and allowing the solids to settle out. The solids are then removed and further dewatered to produce a relatively dry concentrated solid waste phase. If desired, the clarified water is mixed with finely divided activated charcoal to remove various impurities from the clarified water. The mixture of clarified water and charcoal are then filtered to produce a filtrate stream which is further separated to produce pure water and a liquid phase containing dissolved solids. The pure water can then be reused in the drilling process or safely discharged into the environment.
