Abstract: A separation system for use with wells drilled for the purpose of producing hydrocarbons where the primary drilling fluid is air or mist. The separator system includes a horizontal separation tube connected to an exhaust line so that it will receive the exhaust mixture created during the drilling of the well. The separator tube has separator inlet liquid ports defined along the length of the tube. Dump outlet ports are also defined along the length of the tube. Separator liquid is injected into the tube and the solid and liquid components of the exhaust mixture along with the separator liquid will pass out of the tube through the dump outlet ports into a receiving tank. The gas component of the exhaust mixture passes through the separator tube into a secondary separator.
