The oil and gas industry continues to feel increasing pressure to reduce greenhouse gas (GHG) emissions, with methane mitigation emerging as a top priority. Methane, a potent GHG with a global warming potential (GWP) approximately 25 times greater than carbon dioxide, is frequently released during production, compression, and storage activities.
Vent Gas Capture Systems (VGCS) have become a reliable, field-proven solution to address routine venting and recover valuable hydrocarbons. This article provides a detailed, engineering-focused overview of vent gas capture technology, its applications, system advantages, and considerations for implementation.
In Canada’s natural gas sector, compressors aid in gathering, processing, and transmission. As operators aim to improve efficiency and reduce emissions, some have considered retrofitting older compressors with sliding valve mechanisms. While common in some compressors, slide valves are not standard in all installations, raising the question: can they be retrofitted?
Natural gas compression systems often face widely varying pressures and flow rates. Sliding valve compressors are engineered to adapt with adjustable internal valves that modulate capacity in real time. This precise control allows them to maintain high efficiency even as operating conditions change.
