The project will involve changing existing high-bleed natural gas-driven pneumatic controllers (such as level controllers and pressure controllers) to low- or no-bleed. This may be achieved either by replacing the old high-bleed controller with a new low- or no-bleed rate controller, or by modifying the existing high-bleed controller (e.g. by replacing a relay) so that it becomes a low-bleed device. By reducing the bleed (vent) rate of these controllers, emissions of natural gas to the atmosphere, which is primarily composed of methane (CH4), will be greatly reduced.
This activity is not currently required by law and will help both Alberta and Canada to meet its emission reduction targets. The project will aggregate the emissions reductions from multiple sites.
