EPI develops a hydraulic model of an instrument air system including leak survey data and plant flow and pressure data to determine the root causes of insufficient pressure in the system.  Then we can determine the lowest cost approach to restore full design pressure to all users in the system while minimizing costs of rental air compressors.  The hydraulic models identify the most cost effective solution that is carried through the FEED, detailed design, procurement and construction management phases.  EPI's technology based approach combined with our high level of experience enables us to determine the lowest cost piping, dryer and compressor modifications to restore full design pressure to all users of instrument air.  This results in significant improvements in the plant reliability.


Benefits of an Instrument Air and Compressed Air Study:

  • Identify and correct high pressure drop segments in the piping to allow lowering of plant compressor discharge pressure and reduce energy costs
  • Determine where water may be building-up in the piping distribution network that when alleviated will provide improved system capacity
  • Allow for optimal design and operation of instrument air driers to minimize capital costs and operating costs
  • Determine the optimal location of new compressor stations and their required capacity


Instrument Air and Compressed Air Study Capabilities:

  • Accurately determine flow and pressure throughout the system based on on-site field surveys using multiple ultrasonic flow meters and pressure data loggers.
  • Simulate future operational scenarios for a comprehensive understanding of system capacity
  • Determine hydraulic limitations, inefficiencies, and bottlenecks
  • Identify optimum tie-in locations for expansion projects
  • Leak survey quantifies leaks and their effect on system capacity
