Biogas Monitoring – an integral part of AD

Biogas monitoring is proving to be an integral part of biogas plant operation to ensure plant efficiency and staff safety comments Chris Dakin, Managing Director of Gas Data: Biogas will almost always contain sulphur in the form of hydrogen sulphide gas.

This gas is odorous, poisonous and is the source of metal corrosion when present in both its raw form and when combusted in the engine to form sulphur dioxide (SO2), which is why it is important to monitor this gas and control its generation.

All engine manufacturers provide guidelines that state the additional maintenance requirements that must be put in place for any given level of hydrogen sulphide in the gas. Without accurate knowledge of the levels, there is a risk that maintenance will either be carried out unnecessarily or even worse be left undone; both outcomes can be very expensive and detrimental to staff safety, adds Chris.
