CRYOGENIC EXPANDERS
CEX-120 / ENGINEERING REVIEW / R02
CEX-120 Cryogenic Expander
Cold-end expander reference package for continuous cryogenic refrigeration.
A cryogenic expander platform for process refrigeration and cold-end integration. Materials, seals, insulation, and start-up procedures are reviewed against the actual process fluid and temperature envelope.

REFERENCE CONFIGURATION
Published selection basis
REFERENCE FLOW120–2,400 Nm³/h
TEMPERATURE BASISSelected from process composition and metallurgy review
INTEGRATIONCold-box / skid interface by project
PROTECTIONOverspeed, vibration, temperature monitoring
STANDARDS PATHWAY
Applicability must be confirmed
- API 617 project basis
- BS 6364 cryogenic valve interfaces
- ISO 21010 cryogenic compatibility review
Reference platform data only. Cryogenic service limits require a materials review.
APPLICATION ENVELOPE
Intended study contexts
Air separation cold boxLNGIndustrial gas productionHydrogen liquefaction studies
CONFIGURATION PRINCIPLES
- Operating envelope reviewed before geometry is frozen
- Mechanical and control configuration defined by project duty
- Inspection, testing, and release records agreed by scope
OPEN ENGINEERING CHECKS
- 01The published 120-2,400 Nm3/h range is a client draft and needs model-level test evidence.
- 02Confirm minimum design temperature, materials, cleaning, and containment basis.
