Process Technologies

Proprietary Supply (Ethylene Production)

Lummus Technology supports our petrochemical and refining technologies with a variety of engineered products that facilitate conversion, enhance productivity and lower production cost. Our proprietary offerings include: 

  • Catalysts for petrochemical, polymer and refining processes
  • Heat transfer equipment, including fired process heaters, ethylene furnaces and heat exchangers
  • Specialized internals for fluid catalytic cracking (FCC) units
  • Modular pressure swing adsorption (PSA) gas separation units

SRT® Ethylene Furnaces

At Lummus, we have built more ethylene furnaces than any other ethylene process licensor, representing more than 40% of worldwide capacity. In response to the growing ethylene demand we have developed a state-of-the-art pyrolysis furnace. The first generation of the pyrolysis heater called SRT-I (Short Residence Time), was developed in the mid-1960s. Today, the most widely selected SRT furnaces include SRT-III, SRT-V, SRT-VI and SRT‑VII, which are known for their reliability in capacity, yield, run-length and energy efficiency. Together with SCHMIDTSCHE SCHACK-ARVOS, we have also developed the proprietary transfer line exchangers “Bath Tub” and “Quick Quencher.” Which provide quick quench to the cracking effluent for high ethylene yield and extended TLE run-length.

HELIXCHANGER® Heat Exchanger

Leveraging our industry-proven, enhanced heat transfer technology, the HELIXCHANGER heat exchanger provides solutions to common issues such as shell-side fouling, high-pressure drop and vibration. In the HELIXCHANGER heat exchanger, quadrant shaped baffle plates are placed at an angle to the tube axis in a sequential arrangement to create a helical flow pattern. Installed in refining, power and petrochemical facilities worldwide, our heat exchanger technology offers a lower life-cycle-cost solution for extending the operating period between cleaning campaigns of crude preheat exchangers, reducing capital costs in a petrochemical plant and improving energy-efficiency of feed/effluent towers.


Lummus Technology maintains proprietary catalyst formulations tied to our licensed processes. Catalysts improve process economics by steering reactions to higher conversions and yields.
