Acoustical Products Made in USA.
Centrifugal separators play a vital role in petrochemical processing, yet they are among the most acoustically aggressive pieces of high-speed equipment in a refinery. Operating at rotational speeds capable of generating 90–105 dBA, these units produce broadband noise that radiates outward through duct systems, structural framing, and adjacent compartments. Because separators are frequently positioned near monitoring areas and control rooms, their acoustic footprint directly impacts operator concentration and decision-making accuracy.
Separator noise presents unique challenges due to its transmission behavior. The combination of high rotational velocity and mechanical vibration generates layered airborne vs structure-borne sound pathways. Sound energy travels through mounting brackets and steel decks while simultaneously reflecting within enclosed process compartments. This creates cumulative noise buildup that complicates petrochemical plant noise control efforts and increases reliance on PPE for nearby technicians.
Attempting to mitigate separator noise using wall-mounted absorptive panels alone is insufficient. While these panels reduce reflection, they do not prevent direct breakout from the equipment itself. Effective refinery noise mitigation must begin at the source.
ImpactaCore® Acoustic Wall & Blanket Systems provide engineered containment specifically designed to surround centrifugal separator assemblies. These modular sound containment systems isolate high-output equipment while preserving necessary airflow and maintenance access. The mass-loaded barrier layer blocks outward transmission, while the absorptive core reduces internal reverberation and minimizes acoustic pressure buildup inside the enclosure.
By isolating separators directly at the source, facilities achieve measurable decibel reductions, improve overall industrial noise mitigation, and strengthen industrial facility noise management programs. This source-level containment strategy supports compliance with OSHA noise compliance thresholds and enhances long-term oil refinery acoustic solutions performance.
For petrochemical environments where high-speed equipment operates continuously, ImpactaCore® Acoustic Wall & Blanket Systems offer a durable, scalable, and performance-driven solution.
