Proprietary Supply (Residuum Upgrading)

Our innovative ModGrid® catalyst stripper is a novel hardware design commercially proven to increase unit profitability and a reliable solution for all modes of operation.

Designed with the optimal angle, correct exit velocities and thorough feed/catalyst contact necessary to maximize the performance of the unit, they achieve superior yields of valuable light products when replacing conventional injectors.

Used in both grassroots and revamp applications our Reaction Termination Device (RTD), incorporates our proprietary Direct-Coupled Cyclone technology, and is critical in preserving the yields of gasoline and light olefins by terminating the reactions at the end of the reactor riser.

Our air distributors, which include the unique Multi-Stage Orifice (MSO™) nozzle, are designed to provide ultra-stable flow. Through extensive CFD modeling, we have identified the erosion mechanisms often seen in conventional borda tube nozzles.

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.

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.
