Beltana Flaring Facility Project

Project overview

Gas drainage and flaring project; creating safe work environment and reducing the carbon footprint was the key reasons for pre-draining gas from coal prior to mining. Gas that isn’t drained could cause a safety hazard for underground employees and cause delays in production.

Our involvement

Eneraque was responsible for the design, supply, installation, commissioning and on-going support for a 10,000 m³/hr flaring facility. The gas flares are flaring off the pre-drainage gas from an underground coal mine. The gas quality is in the vicinity of 90–98% CH4 and approaching the flares at a flow rate of 10,000 m³/hr. In the gas header before the flares, there is a gas filter system for removing any dust or foreign particles from the gas supply and a pressure reduction system for bringing the gas pressure down to a required flare inlet pressure.

Outcome and benefits

Once the methane is drained and captured, the gas is burnt at a flaring facility, reducing the CO2 footprint by 21 times compared to free venting. The flares installed were a fully enclosed type flare with emissions monitoring complying to the European emissions standards.
