Catalysts and Equipment

Heat Transfer Equipment

For more than 100 years, we have provided process industries around the world with the design and supply of specialized heat transfer equipment. We offer proprietary critical equipment based on patented designs that are essential to the proper functioning and performance of our licensed processes.

Fired Heaters

Lummus Technology has designed and built fired heaters to meet refining and petrochemical industry needs, including refinery heaters, steam superheaters, heaters for delayed coking units and steam reformers, and our patented SRT® (Short Residence Time) pyrolysis heaters for ethylene production. 

Our heaters can be designed to operate under natural draft, forced draft, induced draft or balanced draft conditions, with or without an air preheater system. Some heaters have also been integrated with gas turbine exhaust systems to improve plant energy balance. 

Lummus Technology not only provides new heaters, but also helps customers improve or revamp existing heaters to meet new process requirement. 

DeNOx Units

Lummus Technology designs and supplies DeNOx units, also known as selective catalytic reduction (SCR) units. The SCR unit can be incorporated in a new design, retrofitted in an existing heater or installed during a heater revamp. 

Heat Exchangers

We have designed and supplied more than 25,000 shell-and-tube heat exchangers over the past century, including high pressure applications. Ongoing research and development, along with our ISO 9001 Lloyds-certified quality system, ensure that our advanced equipment meets our customers' requirements. 

Technical Services

In addition to the design and supply of heat transfer equipment, Lummus Technology provides technical support for plant startup, troubleshooting, performance improvement and personnel training. We also provide feasibility studies for projects involving heat transfer equipment. 

Our after-sale service can be extended to help customers evaluate heat transfer equipment and obtain spare parts.

Heat Exchangers

For more than 100 years, Lummus Technology has designed and supplied more than 25,000 shell-and-tube heat exchangers, including enhanced heat transfer and high pressure closure technologies.

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 Advanced Breech-Lock Exchanger®

For over 35 years, the Lummus Advanced Breech-Lock Exchanger has been extensively used in hydroprocessing and hydrogen-rich environments, assuring leak-free performance and easy maintenance. Using our industry-proven high-pressure heat exchanger closure technology, it provides solutions for critical high-pressure and high-temperature services with innovative technology that eliminates the large channel cover flange and bolting of other conventional high-pressure exchanger designs.
