Pressure Vessels and Heat Exchangers

Our capabilities in pressure vessel and heat exchanger technology encompass the following areas, among others:

  • Design evaluations
  • Compliance with ASME Code and specification requirements
  • Development of technical purchase specifications
  • Design details for high temperature, internally lined equipment
  • Engineering design details
    • Catalyst support grids
    • Plenum chamber and cyclone systems
    • Fluidized solids distribution grids
    • Hot/cold nozzle intersections
    • Support skirt intersections
    • Outlet collectors
  • Rerating and repair analysis
  • Tall vessel design
    • Wind
    • Earthquake
    • Process- or wind-induced vibration
  • Shell-and-tube heat exchangers
    • Flange leakage
    • Vibration evaluation
    • Heat transfer duty

Here are a few examples of assignments related to pressure vessel and heat exchanger technology that we have successfully completed:

  • Evaluated existing pressure vessels and heat exchangers for revised design conditions. Demonstrated that vessels were acceptable without changes.
  • Analyzed locally corroded regions of an existing pressure vessel. Demonstrated that the vessel was acceptable for unrestricted operation.
  • Reviewed vendor design of large, horizontal pressure vessel intended for hazardous waste storage. Found major errors in saddle support design and in minimum temperature limit for use.
  • Developed mechanical design purchase specification for a large high-temperature steam generator. Performed bid conditioning review of vendor design and participated in vendor selection.
  • Performed design analysis of cyclone plenum systems for vessels containing fluidized solids. Initiated changes to vendor-proposed design to adequately carry design loads.
  • Designed and prepared stress analysis of distribution grids for large, fluid-solids unit vessels. Prepared design specifications for vendor quotation.
  • Prepared failure evaluation of distribution grid supports in fluid-solids unit vessels.
  • Gave onsite turnaround assistance in inspection and evaluation of fluid-solids unit vessels.
  • Analyzed reactor outlet collectors to determine acceptable differential pressure to avoid a unit shutdown.
