Sulfinol-X is a technology development for Acid Gas Removal based on long-term design and operational experience with both traditional hybrid solvents such as Sulfinol-D and accelerated MDEA solvents. Case studies are presented showing the potential benefits of Sulfinol-X, both for revamps of existing and design of new plants. Benefits include increased capacity, energy reduction, lower chemicals consumption and waste disposal, tighter CO2, H2S and COS specifications and simplified process schemes. For new plants the case demonstrates that simplicity and reliability can be realized with Sulfinol-X, while reducing CAPEX significantly compared to traditional accelerated MDEA schemes for highly contaminated gases. Two examples are presented utilizing the Sulfinol-X technology, demonstrating the predicted advantages and long term stability of the new solvent.
