Polyurethane Insulated Accumulators

A polyurethane insulated accumulator is a pressure vessel designed to store process fluids, dampen pressure fluctuations, or provide surge capacity while maintaining controlled temperatures through integrated polyurethane foam insulation. These vessels ensure stable operating conditions and protect temperature-sensitive processes from upset conditions.

Why are Polyurethane Insulated Accumulators Needed?

Polyurethane insulated accumulators are essential for processes requiring temperature-stable buffer capacity or surge protection. The superior thermal resistance of polyurethane insulation maintains product temperatures during residence time in the accumulator, preventing quality degradation and ensuring consistent downstream process conditions.

Polyurethane Insulated Accumulators Applications

Common applications include:

  • Reflux accumulators
  • Suction drums for compressors
  • Surge vessels
  • Buffer tanks
  • Receiver vessels
  • Blowdown drums

Polyurethane Insulated Accumulators Frequently Asked Questions (FAQs)

Why insulate accumulator vessels?

Accumulators often hold process fluids for extended periods during normal operation or upset conditions. Polyurethane insulation maintains fluid temperatures, preventing condensation, viscosity changes, or product degradation that could affect downstream process performance. Insulation also enables accumulators to serve as effective thermal buffers in the process system.

What instrumentation is typically included on insulated accumulators?

Standard instrumentation includes level indication and control, pressure indication and relief, temperature indication, and appropriate process connections. The insulation system is designed with insulation boots around instrument connections and removable sections for maintenance access to critical components.

Can accumulators be designed for both liquid and vapor service?

Yes, our polyurethane insulated accumulators can be designed for liquid service, vapor service, or combined liquid-vapor service. Design considerations include proper inlet devices, vapor-liquid disengaging space, mist elimination, and appropriate nozzle sizing. The insulation system provides consistent thermal protection regardless of service type.
