Gas Liquefaction Systems – Greenox Gases
Advanced Cryogenic Liquefiers for Industrial Gases | Teamwin & Yuanhan Partnership
Greenox Gases delivers high-efficiency gas liquefaction systems through our strategic partnership with Teamwin (cryogenic equipment) and Yuanhan Energy (process technology), providing reliable, energy-optimized solutions for liquefying argon, CO₂, nitrogen, oxygen, and other industrial gases.
A Gas Liquefaction System is an industrial process used to cool gases to very low temperatures until they condense into liquid form.This process involves cooling the gas to extremely low temperatures, often using refrigeration cycles, until it condenses into a liquid.
Liquefaction Technology Overview
How It Works
Our systems use cryogenic cooling, compression, and expansion cycles to convert gases into liquid form at ultra-low temperatures:
- Nitrogen/Oxygen/Argon: –196°C (77K) via Claude Cycle
- CO₂: –56.6°C (216.6K) via Cascade Refrigeration
- Custom Gases: Specialized cycles for hydrogen, helium, etc.
- Key Partners:
- Teamwin – Fabricates ASME-certified cold boxes, heat exchangers, and storage tanks
- Yuanhan Energy – Provides energy-recovery turboexpanders and AI-driven process control
