Introduction: Redefining Excellence in BTX Extraction


Refineries and petrochemical producers face growing pressure to maximize yield, purity, and sustainability for aromatics like benzene, toluene, and xylene (BTX). With global markets demanding cleaner, higher-value products and operational efficiency, the choice of extraction solvent is now a critical competitive advantage.

Sulzer, a recognized leader in separation technology, introduces Techtiv™ solvent—a breakthrough solution setting new performance standards in BTX extraction. Engineered for superior selectivity and nitrogen-free formulation, Techtiv™ enables refineries to achieve exceptional results in both Liquid-Liquid Extraction (LLE) and Extractive Distillation (ED) units.


What Makes Techtiv™ Solvent Unique?


Unmatched Selectivity and Purity

Techtiv™ is formulated for ultra-precise separation of aromatics from complex hydrocarbon mixtures. With selectivity far beyond traditional sulfolane, Techtiv™ delivers BTX purities of ≥99.9% and recovery rates well above 99.9%, even with challenging feeds like catalytic reformate and pygas. This unlocks value from every feedstock and minimizes losses.


Sustainability at the Core

Unlike older solvents, Techtiv™ is designed to reduce energy consumption and environmental impact. Its nitrogen-free formula avoids catalyst poisoning and limits solvent degradation, lowering replacement frequency and supporting reliable, eco-friendly operation.


Lower Solvent-to-Feed Ratios

Techtiv™’s high solvency means units run efficiently with much less solvent. This results in lower steam, electricity, and cooling water consumption, helping refineries cut operating costs and reduce their carbon footprint.


Advanced Features for Modern Operations


  • Non-toxic & Thermally Stable: Safer operation, corrosion and hazard reduction, and robust performance under fluctuating process conditions.

  • Drop-In Compatibility: Techtiv™ can be introduced into existing assets—no costly modifications or downtime required, making upgrades fast and cost-effective.

  • Operational Experience: More than 50 BTX units worldwide have used Sulzer’s solvents, and Techtiv™ draws on this vast expertise and field-tested reliability.


Sulzer’s GT-BTX™ Technology Powered by Techtiv™ Solvent


Sulzer’s advanced GT-BTX™ extractive distillation technology uses Techtiv™ solvent as a core component, offering:

  • Optimized column design for high selectivity and easy operation

  • Ultra-low solvent loss and minimal environmental emissions

  • Suitable for a wide range of feedstocks, including combination streams and heavy aromatics


Real-World Impact: Case Study


A major Asian refinery faced solvent degradation and frequent shutdowns with traditional chemicals. After switching to Sulzer’s Techtiv™, their BTX unit achieved >99.9% aromatics recovery and reduced steam use by 15%. The transition was seamless, with no capital investment or plant revamp required—providing immediate ROI and sustainability gains.


Conclusion: Setting the New Standard in BTX Extraction


Sulzer’s Techtiv™ solvent is more than just a chemical—it’s a leap forward in aromatics extraction, purity, and process economics. With unmatched selectivity, easy integration, and proven operational savings, Techtiv™ enables refineries and petrochemical plants to meet today’s toughest demands for efficiency and sustainability.
