This one stage research project seeks to undertake a practical study to gain a better insight on the actual leakage rates from selected venting controllers.
This study will be used to inform a potential further piece of work to develop an extended modelling approach to predict the emission rates on a regional basis and to quantify the emission savings through a controller change-out. The expected benefits of this work will be reduced losses of natural gas at Above Ground Installations (AGIs) and reduced carbon footprint for AGI site operations related to valve positioners and controllers.
