EverGreen Minimal Environmental Impact Well Effluent Burner

Overview Library

Clean disposal of well effluent

The EverGreen minimal environmental impact well effluent burner is a single-head, 12-nozzle, well test oil burner for onshore and offshore exploration and development well testing and cleanup. It performs a fallout-free and smokeless combustion of liquid hydrocarbons produced during well testing. The burner geometry makes extensive use of pneumatic atomization and enhanced air induction. The burner is equipped with twin pilots, a flame-front ignition system (BRFI), and a built-in water screen to reduce heat radiation. The EverGreen burner is also fitted with an automatic shutoff valve that prevents oil spillage at the beginning and end of a burning run.

It has been proved that the EverGreen burner is highly efficient with all types of oil, particularly heavy and waxy oils. The Evergreen burner can operate effectively with up to 25% water cut, which makes it ideal for cleanup operations and an important element in the CleanTest well testing service platform. Because it eliminates liquid fallout, visible smoke emissions, and oil dumping at the end of a burn sequence, the EverGreen system is particularly well suited for operations in environmentally sensitive areas.

Development of the EverGreen burner was accomplished with the support of the European THERMIE program and with the combustion expertise of Institut Francais du Pétrole (I.F.P.).

All EverGreen burners are manufactured under a Type Approval and Design Verification Review and are provided with a Certificate of Conformity and a full quality file.
