CEX / FAMILY SELECTION GUIDE

Cryogenic Expanders

Reference cold-end expansion platforms for cryogenic process studies. Minimum design temperature, compatibility, cleanliness, thermal contraction, containment, and cold-box interfaces require service-specific review.

SELECTION INPUTS

What engineering needs first

01Fluid composition, purity, contaminants, and phase envelope
02Normal and transient pressure-temperature-flow cases
03Minimum design metal temperature and thermal cycles
04Cold-box, skid, insulation, purge, drainage, and removal interfaces
05Containment, cleaning, inspection, test, and preservation requirements

VERIFICATION OUTPUTS

What closes the release gate

Gas/material compatibility review
Low-temperature material and joining qualification
Thermal movement and nozzle-load review
Leak, functional, mechanical, and performance-test scope
