FAQ
Q: Can the system handle sour gas containing H₂S?
A: Yes, the system can be engineered for sour gas applications, with H₂S tolerance up to 5,000 ppm depending on gas composition and project-specific design conditions.
Q: What is the system's operating flexibility under changing gas conditions?
A: The system is designed to maintain stable performance under variable feed conditions, including fluctuations in flow rate, pressure, and CO₂ concentration within the design range.
Q: What ensures stable CO₂ removal performance during operation?
A: Stable performance is maintained through automated process control and continuous monitoring of key operating parameters, allowing the system to adjust to process variations in real time.
Q: How does the system ensure long-term operational reliability?
A: Long-term reliability is achieved through corrosion-resistant materials, controlled operating conditions, and continuous monitoring of solvent condition and process stability.
Q: What are the downstream CO₂ handling options?
A: Captured CO₂ can be conditioned for industrial use, enhanced oil recovery (EOR), or geological storage depending on project requirements and compression specifications.
