Reciprocating Compressor Design & Analysis

Reciprocating Compressor Design Services & Problem Diagnosis

Since reciprocating compressors are a mainstay of industry, their performance and reliability can have a considerable impact on plant productivity. Southwest Research Institute (SwRI) offers a line of services to apply as early as possible in the design and operating stages for troubleshooting reciprocating compressor problems, such as:

  • Vibration
  • Pulsation
  • Performance
  • Thermal Stress

From pulsation control to skid finite element analysis (FEA) design and from field support to transient surge analysis, Southwest Research Institute (SwRI) employs the most experienced and knowledgeable design team for your compressor station. SwRI has an experienced and knowledgeable design team that has:

  • Designed and analyzed more than 12,000 installations worldwide since 1955
  • Optimized pulsation and mechanical solutions for best performance and lowest installed cost
  • Advanced low-loss pulsation control technologies customized for your system
  • Field validated best-in-class analysis software for accurate analysis
  • Design staff with more than 300 years of combined gas compression experience
  • Field troubleshooting services: On-site field pulsation and vibration analysis and testing

Commercially available and internally developed software, coupled with field experience on past installations, is used by Southwest Research Institute engineers to:

  • Predict system dynamic characteristics
  • Assess the potential for problems
  • Identify modifications that will reduce the chance of problems
  • Identify operating ranges to be avoided
  • Define any areas of risk or uncertainty to be validated during startup

These design services are applicable to systems associated with the following machine types:

  • Reciprocating compressors
  • Centrifugal compressors
  • Pumps
