GT-BTX PluS™: Lowering Operating Costs and Boosting Sustainability in Aromatics Recovery

Introduction

As energy prices and environmental concerns rise, refineries require cost-effective, sustainable solutions for gasoline upgrading and aromatics recovery. Sulzer’s GT-BTX PluS™ is engineered to reduce both operational expenses and environmental footprint, offering a strategic advantage for refineries processing FCC gasoline.

How GT-BTX PluS™ Reduces Costs

• Simultaneous Operations

  GT-BTX PluS™ consolidates BTX aromatics recovery and sulfur removal into a single process step. This innovation directly cuts capital and operating expenses by minimizing required equipment, utilities, and total processing time.

• Energy and Hydrogen Savings

  By leveraging advanced extractive distillation design and specialized solvents, GT-BTX PluS™ achieves high-efficiency separation with lower energy demands. Reduced hydrogen consumption further lessens refinery variable costs and carbon impact.

• Preservation of Gasoline Octane

  Unlike conventional processes that sacrifice gasoline octane or product quality, GT-BTX PluS™ maintains highest gasolineoctane while extracting maximum value from every feedstock barrel.

  
  

Sustainability and Environmental Impact

• Lower Energy Consumption

  The integrated system design delivers significant energy savings, directly reducing greenhouse gas emissions and overall environmental impact.

• Cleaner End Products

  By producing ultra-low-sulfur, high-octane gasoline and ultra-pure BTX, refineries achieve compliance with stringent global regulations, supporting public health and environmental goals while maximizing the profitability.

• Efficient Use of Feedstocks

  The process allows refineries to convert previously lower-value streams into premium fuels and petrochemicals, increasing overall resource efficiency.

  
  

Real-World Benefits

• Sulzer GT-BTX PluS™ technology is selected by large refineries globally, including in major projects such as those at CPC Corporation, Taiwan, where the technology is integral to large-scale aromatic production and gasoline upgrading, driving operational profitability and sustainability.

• The process can seamlessly retrofit into existing assets or be used in new installations, giving refineries flexibility and risk-free integration with proven performance.
