GT-BTX PluS™: Flexible Solutions for Retrofit, Expansion, and New Builds

Introduction

In today’s rapidly evolving refining landscape, flexibility is essential to meet changing market demands, regulatory requirements, and feedstock variations. Sulzer’s GT-BTX PluS™ technology offers unmatched adaptability, making it the ideal choice for refineries planning new units, retrofits, or capacity expansions. This comprehensive solution integrates easily into diverse refinery configurations, enabling operators to optimize aromatics recovery and sulfur removal regardless of operational context.

Installation and Integration Options

• New Builds GT-BTX PluS can be designed into greenfield refineries, allowing full customization of process layout and equipment sizing. A new installation benefits the refinery to have capability to produce ultra-low sulfur FCC gasoline with near-zero octane loss, and have flexibility to produce high-quality high-value BTX aromatics product when the market requires.

• Retrofit Applications Existing FCC gasoline units can be upgraded with GT-BTX PluS technology to enhance process performance, product quality, and environmental compliance without major overhauls. Its flexibility to switch between gasoline mode with highest octane number and petrochemical mode with high-value BTX production can be the life saver for refinery to adapt the fast market change without additional investment.

  
  

Advantages of Flexible Deployment

• Feedstock Versatility

  GT-BTX PluS™ effectively processes a wide range of FCC gasoline feedstocks, including variations in sulfur, olefin content, and aromatics content. This flexibility ensures consistent performance even as crude slates or product demands shift.

• Dual Production Modes

  Refineries can adjust operation between producing higher volumes of low-sulfur, high-octane gasoline and maximizing petrochemical-grade BTX output switching easily according to market or regulatory needs. When paired with related technologies such as Prime-G+®, this flexibility becomes a significant competitive advantage.

• Rapid Return on Investment

  With the simple two-column extractive distillation process, GT-BTX PluS™ has low capital and operating costs. Combining with high value addition regardless of gasoline mode or petrochemical mode, the unit always provides speedy project return.

• Proven Field Experience

  The technology has been successfully deployed in large-scale projects worldwide, showcasing reliability, ease of integration, and robust performance under varying operating conditions.

  
  

Case Highlight: Flexible Operation in Practice

At a major petrochemical complex in Eastern Europe, GT-BTX PluS was selected for a benzene unit aimed at processing FCC gasoline from multiple sources. The plant achieves higher benzene purity and improved cost efficiency, while maintaining the ultra-low sulfur and high-octane gasoline production.
