Mining
Environmentally friendly disposal of mine gas
When the methane gas is drained and captured, the gas can be utilized or destroyed in a high-temperature flaring facility. The gas can be used for power generation or heat recovery. In those cases, the Hofstetter enclosed combustion system is applied as a safeguarding and emergency system.
Hofstetter collaborates closely with Watergasrenew Pty from Australia. Watergasrenew PTY has extensive knowledge and experience in coal mine operations and gas extraction systems. This partnership makes it possible to comply with the strictest mining regulations and offer the full engineering package including FMEA, HAZOP and cause & effect analyses. Our in-depth knowledge enables us to offer the best possible technical and most economical advice on how to handle your de-gassing issues.
