Lanran CCUS Application Solutions Series | Case VI
Case: A Refining & Petrochemical Amine Purification Project in Zhejiang Background: This refinery operates one of Asia’s largest co-exes (40 million t/a refining capacity). Its MDEA (Methyldiethanolamine) solvent system is used for H₂S and CO₂ removal from process gases. Originally, the company used anion resin beds for HSS removal. However, resin replacement was costly, suffered from sodium ion leakage, and could not achieve stable low-HSS operation. Lanran Solution: In 2024, the refinery replaced its resin system with Lanran’s ED416-250 electrodialysis stacks. Amine solvent circulates through the ED stack. Under a DC electric field, harmful HSS anions are selectively removed. Solvent is regenerated without chemical regenerants. The target was to reduce HSS from 6% → 0.5%. Technology Advantages ✔ Superior to resin-based purification – lower cost, better performance. ✔ Maintains long-term solvent stability. ✔ Provides a robust solution for large-scale refineries. Results & Impact By March 2025, both East and West refining zones achieved stable operation with HSS at 0.5%. After six months, solvent quality remains stable at the same level. Energy consumption and chemical costs have been significantly reduced.
Lanran Tech’s CCUS Amine Purification Electrodialysis Project has been recognized as a 2025 Green Trade Demonstration Case
Lanran Tech’s CCUS Amine Purification Electrodialysis Project has been recognized as a 2025 Green Trade Demonstration Case at the China International Import Expo (CIIE) and will be featured at the International Green Trade Conference. Our technology supports the world’s first 100,000 t/a green methanol project, providing key solutions for carbon capture and contributing to global climate action with innovative, sustainable membrane technology. We look forward to joining the Green Trade Policy & Case Sharing Session on November 8 in Shanghai to exchange ideas on building a cleaner, greener future.

Lanran CCUS Application Solutions Series | Case V
Case: 2,000,000 t/a CO₂ Capture & Storage Base at a steel producer in Inner Mongolia Background: A major steel producer launched China’s first 2,000,000 t/a CCUS base, built in three phases (500,000 + 500,000 + 1,000,000 t/a). Phase I was completed in 2024, marking a milestone in low-carbon steelmaking. Steel plant flue gas contains impurities that degrade amine solvents. To ensure efficient CO₂ capture, continuous HSS removal was required. Lanran Solution: Lanran provided AC50-180 ED stacks (supplied through an EPC contractor). The amine solvent passes through the ED membranes. Negatively charged HSS ions migrate out, while valuable amines are retained. This keeps the solvent reactive and reduces degradation. Technology Advantages ✔ Supports scalable CCUS in high-emission industries. ✔ Ensures solvent efficiency in harsh flue gas conditions. ✔ Reduces OPEX (operating expenses) compared with resin replacement. Results & Impact: Phase I: 500,000 t/a CO₂ captured successfully. Provides a low-carbon pathway for China’s steel industry. Reduced solvent replacement costs and extended amine lifecycle.
