Sulzer Techtiv - Decarbonizing BTX extraction units
Overview
Techtiv™ Solace is Sulzer’s newest solvent portfolio, featuring superior selectivity and solvency. It is poised to revolutionize Liquid-Liquid Extraction (LLE) and Extractive Distillation (ED) units by offering tangible benefits over traditional solvents, such as sulfolane, and even systems that currently use Sulzer’s market leading solvent, the first generation Techtiv.

Techtiv™ Solace stands out with three main benefits: higher BTX recovery and purity, reduced energy consumption, and increased capacity. Thanks to its advanced selectivity and solvency, it delivers measurable process improvements while offering a drop‑in installation—meaning no plant shutdown or major modifications are needed.
Yes. Techtiv™ Solace is designed as a direct replacement (“drop‑in”) for sulfolane or first‑generation Techtiv solvents. It can be introduced while the unit is in operation, allowing refiners and petrochemical producers to realize efficiency gains in as little as one month without halting production.
By enabling lower solvent-to-feed ratios and improving process efficiency, Techtiv™ Solace cuts demand for steam, electricity, and cooling water. These energy savings directly reduce operating costs and lower CO₂ emissions, helping plants meet sustainability and decarbonization targets faster.
Operators typically notice immediate improvements in throughput, recovery yield, and product quality of aromatics like benzene, toluene, and xylene (BTX). The reduction in utility needs also decreases operational expenses, making the switch both a performance and profitability upgrade.
Yes. The solvent is non‑toxic, non‑reactive, thermally stable, and fully compatible with existing sulfolane handling procedures. It reduces corrosion risk and requires no special storage or transfer systems, making the transition safe, simple, and low‑risk for operators.
