REFERENCE CONFIGURATION

Published selection basis

CONFIGURATIONCryogenic expander module
SERVICEClean, dry process gas after upstream treatment
SEALINGApplication-selected dry gas or labyrinth concept
INSTRUMENTATIONTemperature, vibration, speed, pressure

STANDARDS PATHWAY

Applicability must be confirmed

  • API 617 project basis
  • ISO 21010 cryogenic compatibility review
  • IEC 61511 interface where applicable

Reference platform data only. Cleanliness and start-up requirements are duty-specific.

APPLICATION ENVELOPE

Intended study contexts

LNG peak shavingNitrogen productionOxygen productionNatural gas liquids

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

  1. 01Confirm cold-box and skid interfaces, purge, drainage, and removal path.
  2. 02Release gas/material compatibility and start-up/shutdown limits.
