Since 1934, Lummus Technology's Heat Transfer group has been providing process industries worldwide with the design and supply of specialized heat transfer equipment.

Fired Heaters

We have designed and built fired heaters of every size and type, often as the forerunner in the field of new design applications, technology and pollution control. Our experience list includes:

• SRT (Short Residence Time) pyrolysis heaters for the ethylene industry. SRT heaters are used to produce more than 40% of the world's annual ethylene capacity.
• Steam reformers for applications in ammonia, methanol, hydrogen and town gas plants, and for the reduction of iron ore.
• More than 60 heaters for visbreaking projects.
• Fifty percent of the world's existing cokers.
• Several hundred crude and vacuum heaters.
• Charge and recycle heaters for hydrocracking processes, some with pressures as high as 325 bar (4600 psi) and temperatures up to 550 degrees C (1020 degrees F).
• More than 100 catalytic reformers.
• Special purpose heaters for refining processes such as alkylation, solvent refining and sulfur recovery, and for petrochemical processes such as styrene and vinyls production.

Air Preheaters

We offer cast iron preheaters, tubular systems, regenerative systems and preheaters used on gas turbine units to preheat air against exhaust gas.

Heat Exchangers

We have designed and supplied more than 20,000 shell-and-tube heat exchangers over the past 60 years, including high pressure applications. Ongoing research and development, along with our ISO 9001 Lloyds-certified quality system, ensure that our advanced equipment meets our clients' requirements.

One innovation is the HELIXCHANGER^® helically baffled heat exchanger, is currently applied in more than 1,800 applications. Quadrant-shaped segment baffle plates are positioned at an angle to the tube axis in a sequential arrangement to guide the shellside flow into a helical pattern. The result is reduced capital cost and life cycle cost, improved thermal effectiveness, enhanced heat transfer, reduced pressure drop, lower fouling and significantly reduced vibration hazards.
