Executive Summary
Glycol dehydration units in Alberta commonly over-circulate glycol, which results in more energy use and emissions, with negligible reduction in dry gas water content due to the extra circulation. In addition, stripping gas is commonly employed year-round, where it may only be required seasonally or not at all to ensure adequate drying of the gas.
Optimization of the operating conditions of the units can provide an opportunity to both reduce operating expenses (ie: recover fuel gas revenue from wasted fuel) and simultaneously reduce emissions of greenhouse gases and other contaminants.
