Natural Gas Decarbonization Equipment

Product Overview

Natural gas decarbonization equipment is a high-efficiency system specifically designed to purify natural gas by removing acidic gases (such as CO₂ and H₂S), moisture, and other impurities. Using methyl diethanolamine (MDEA) solvent absorption, the system ensures that natural gas meets high-quality standards before low-temperature liquefaction, preventing pipeline and equipment corrosion or blockage and ensuring safe, efficient operation of downstream processes.

Working Principle

Natural gas enters an absorption tower and contacts the MDEA solution. CO₂ and H₂S are selectively absorbed into the liquid phase, achieving effective gas purification.

The rich solution is sent to a regeneration system, where absorbed acidic gases are released via heating or pressure reduction, restoring the solvent’s activity for continuous recycling. The system incorporates multi-level safety controls and automated management, enabling stable, continuous operation while optimizing energy efficiency.

Key Features

• High-Efficiency Acid Gas Removal: MDEA absorption effectively reduces CO₂ to below 50 ppmV and H₂S to below 4 ppmV.
• Advanced Automation: Fully automated control with multi-level safety protection for reliable and convenient operation.
• Energy-Efficient Regeneration: Optimized regeneration process reduces energy consumption while enhancing overall system efficiency.
• Compact Design: Minimal footprint allows for easy installation and maintenance, meeting modern industrial requirements.
• Stable Long-Term Operation: Ensures consistent natural gas purification quality and protects downstream processes.

Applications

• Natural Gas Liquefaction: Pre-liquefaction decarbonization and purification to ensure high-quality LNG output.
• Oil & Gas Industry: Purification and decarbonization of natural gas for safe transport and industrial use.
• Environmental Protection: Removal of harmful gas components to reduce environmental pollution and meet regulatory standards.
