5. The Biggest Cost Savings of All ...! Over stating your methane, greenhouse gas emissions is not a good thing. • Rel-Tek’s wide-spectrum GasBoss sensors properly account for all combustible constituents of NG, including methane, ethane, propane and hydrogen -- as they actually contribute to the LEL. There is no over-reaction to ethane. • The “ethane catastrophe” was discovered by the British decades ago… wherein optical sensors inherently overreact to ethane. The world’s coal mines use catalytic bead sensor technology to avoid such errors from optical (NDIR) devices. • Optical (NDIR) sensors widely used on Marcellus gas wells typically over-react to the inevitable ethane content of NG, exaggerating the methane greenhouse gas emission by a factor of 20x. This is due to the huge optical footprint of ethane making just 1% ethane read as 20% methane. • Solution: Eliminate undeserved fines and assessments for ethane-inflated greenhouse gas (methane) emissions. • Total cost savings can be very large figures, even exceeding the initial price.
