GT-BTX is Sulzer’s most advanced extractive distillation technology designed for efficient aromatics extraction and BTX recovery from refinery, petrochemical, and coke oven streams such as catalytic reformate, pyrolysis gasoline, and coke oven light oil (COLO).
GT-BTX uses a state-of-the-art two-column extractive distillation system and proprietary top-performing Techtiv solvent for superior separation, offering higher process efficiency, higher aromatics recovery, lower capital and operating costs, and easier operation compared to traditional liquid-liquid extraction and other distillation processes that use sulfolane, NFM, NMP, glycol, or any other conventional solvent.
GT-BTX is highly flexible and can process a wide range of BTX-rich feedstocks, including reformate, pyrolysis gasoline (pygas), and coke oven light oil (COLO), without requiring special pretreatment.
The technology consistently delivers ultra-high purity aromatics (≥99.9 wt%) at exceptional recovery rates (>99.9%), meeting the most stringent standards for downstream applications. It also has record-low energy consumption comparing to other aromatics extraction processes, low investment, extremely low solvent consumption, and robust operation.
Techtiv™ is a proprietary solvent developed for GT-BTX, offering optimal selectivity, stability, and extraction efficiency. It also reduces environmental impact and ensures nitrogen-free benzene output. Comparing to all other solvents used for aromatics extraction, such as sulfolane, NFM, NMP, and glycol, it proves to have superior performance in both selectivity and solvency, result in more efficient aromatics separation & purification from non-aromatics, with lower energy consumption and smaller equipment.
Yes, GT-BTX is ideal for new plants, revamps, or debottlenecking projects, providing seamless integration, operational flexibility, and rapid return on investment. GT-BTX in revamp cases can improve the existing unit’s aromatics recovery, aromatics purity, increase capacity, reduce energy consumption, reduce solvent loss, and/or increase system stability.
