Technip Energies Unveils Breakthrough Low-Emission Furnace for Cleaner Ethylene Production

In a bold step toward decarbonizing the petrochemical industry, Technip Energies has unveiled a low-emission furnace (LEF) design that promises to significantly reduce carbon dioxide emissions from ethylene production—an industry notoriously known for its heavy environmental footprint. This pioneering technology offers a game-changing solution in balancing industrial growth with climate responsibility.

Ethylene, a core component used in everything from packaging materials to textiles and pharmaceuticals, is traditionally produced through a high-energy process called steam cracking, which contributes substantial CO₂ emissions. With the global demand for ethylene soaring, the industry has been under pressure to evolve toward cleaner processes. Technip Energies has taken this challenge head-on with its innovative low-emission furnace technology.

Next-Gen Furnace Technology Reduces Emissions, Boosts Global Sustainability Efforts

Ethylene is often referred to as the “building block” of the modern petrochemical industry. It plays a central role in the creation of plastics, antifreeze, detergents, and even synthetic rubber. However, the steam cracking furnaces used to produce ethylene consume massive amounts of fuel and release large volumes of carbon dioxide into the atmosphere.

Traditional efforts to reduce emissions have often struggled to meet both economic and environmental expectations. Technip Energies’ LEF design, however, has succeeded in doing both.

The Innovation Behind the Low-Emission Furnace

At the heart of this breakthrough is Technip Energies’ decades-long commitment to improving the thermal efficiency of cracking furnaces. The newly developed LEF optimizes combustion and harnesses waste heat more effectively than ever before.

Key features of the LEF design include:

• Flue gas combustion air preheating, which reduces fuel demand
  
• A feed effluent Transfer Line Exchanger (TLE), which integrates multiple process steps for maximum thermal efficiency
  
• Use of double pipe and shell-and-tube feed effluent TLE systems, tested and validated in the Netherlands and now being implemented globally
  

These innovations together allow the LEF to cut furnace CO₂ emissions by up to 30%—a remarkable achievement in an industry where single-digit reductions are considered successful.

Proven Success and Real-World Deployment

Technip Energies’ confidence in the LEF’s real-world applicability is backed by successful pilot projects and full-scale implementation. In 2024, the company completed testing of the double pipe TLE system in the Netherlands, leading to a significant contract with Chevron Phillips Chemical Company (CPChem) for its Sweeny facility in Texas, USA.

In 2025, the shell-and-tube TLE system also passed rigorous testing and is now being rolled out in key international projects, such as:

• CSPC III low-emission mixed-feed cracker in China (capacity: 1600KTA)
  
• IOCL’s low-emission cracker in India (capacity: 1500KTA)
  

These deployments showcase the scalability and adaptability of LEF technology across markets and geographies, making it a viable solution for global ethylene producers looking to green their operations.

Beyond Emission Reduction: Economic and Social Impact

The low-emission furnace doesn’t only offer environmental gains—it also delivers economic and social value:

• Lower capital expenditure (CAPEX) and operational expenditure (OPEX)
  
• Increased energy efficiency, translating into lower long-term production costs
  
• Job creation and investment through projects like CPChem Sweeny
  
• Scalability, enabling adaptation in both existing and new production units
  

Furthermore, the technology is future-ready, with potential to integrate 100% hydrogen firing or carbon capture systems, positioning it at the forefront of next-generation green manufacturing.

A Vision for a Carbon-Neutral Future

Technip Energies’ commitment to sustainability and innovation is not new. The LEF is a continuation of the company’s mission to offer cleaner solutions without compromising on performance or profitability. By enabling a dramatic drop in CO₂ output from one of the industry’s largest emitters, the company sets a new benchmark for industrial responsibility.

The timing of this innovation is critical. As nations and corporations push toward net-zero targets, scalable solutions like the LEF could become a cornerstone of decarbonization strategies across the chemical sector.

A Call to Action for the Industry

The success of the LEF underscores the urgent need—and the possibility—for industrial transformation. Other players in the petrochemical space now have a proven model to emulate, thanks to Technip Energies’ bold approach to tackling one of the toughest challenges in industrial sustainability.

In a sector traditionally viewed as difficult to decarbonize, the low-emission furnace stands out as a beacon of innovation and optimism. It’s not just a technological achievement—it’s a demonstration of what’s possible when engineering excellence meets environmental stewardship.

As Technip Energies continues to work with partners across the globe to scale up this breakthrough, the industry can look forward to a future where clean ethylene production is not just an ambition, but a standard.

With its low-emission furnace design, Technip Energies is leading the charge in redefining how essential materials like ethylene are produced—more responsibly, more efficiently, and with far less environmental impact.

As the world transitions to a greener industrial future, solutions like this not only prove that cleaner alternatives are viable but also show they can be more profitable and scalable than ever before.

In Technip Energies’ hands, the future of petrochemicals is looking cleaner, smarter, and more sustainable.
