The modal attenuator consists of a series of carefully engineered resonant cavities to provide sound reduction across a wide spectrum of frequencies. The full-bore design allows unrestricted flow, and internal drain channels drain off condensate which could build up in the device and reduce performance. Installed just downstream of the valve, the modal attenuator achieves an overall sound reduction up to 15 dBa, while creating no restriction in flow capacity whatsoever. The device can be used on existing valves or paired with a low noise control valve to achieve even higher levels of noise reduction. Unlike diffusers or silencers, the modal attenuator works consistently across a wide range of flow rates.
Zero Emission Well Pad of the Future
Ben Fletcher, Manager of Oil & Gas Industries at Fisher Control Valves, recently published an article in the October 2022 issue of World Oil. It is titled “Achieving the Zero Emission Well Pad of the Future” and it discusses the latest round of EPA regulations, and automation solutions which can be deployed to address them. The article is summarized below.
