Selas Fluid Processing Corporation GOX3000 Air Separation Facility

Project Scope

Selas Fluid Processing Corporation/Linde Gas constructed a 3,000 ton/day air separation facility near Lewisville, Arkansas for the purpose of producing and selling liquefied nitrogen and liquefied oxygen.  The main components of the air separation facility are a 12,000HP/13.2kV Recycle air compressor, 2,500HP/13.2kV Main air compressor, cryogenic cold box and storage for liquefied oxygen and liquefied nitrogen.

Excellence Engineering, LLC provided detailed electrical design services for the ISBL portion of the air separation facility. Excellence’s deliverables included area equipment location plans, area grounding plans & details, area lighting plans & details, cable tray details, underground duct bank routings & details, conduit & cable schedules, panelboard schedules, 15kV & 480V electrical one-line diagrams, 480V motor starter schematics & wiring diagrams, 15kV switchgear schematics & wiring diagrams, annunciator wiring and electrical heat trace piping isometrics & installation details.
