What Elessent Clean Technologies does

Elessent Clean Technologies is a global provider of proprietary process technologies, equipment, catalysts, and engineering services for the metals, fertilizer, chemicals, and oil refining industries. The company's portfolio is anchored by four flagship technology platforms: MECS sulfuric acid production technologies (including HRS heat recovery, DynaWave wet scrubbing, MAX3 single absorption, and SolvR regenerative SO2 recovery); STRATCO alkylation for high-octane gasoline production; BELCO wet scrubbing and gas cleaning for air pollution control (NOx, SOx, HCl, particulate); and IsoTherming hydroprocessing for clean fuel production. These are complemented by the Brink fiber bed mist eliminator line (installed at 5,000+ facilities in 100+ countries since 1958), the recently acquired Sulphurnet filtration portfolio, ZeCor acid coolers, proprietary sulfuric acid catalysts (XLP-100 and cesium-promoted variants), the TMODS dynamic simulator engine, and the EleSAF technology for sustainable aviation fuel.

The company traces its technology heritage to MECS catalyst products first introduced in 1925, and was formed on January 1, 2022, when a private equity consortium comprising BPGC Management LP, Asia Green Fund, and Saudi Arabia's Dussur acquired DuPont's Clean Technologies business. Elessent operates from its global headquarters in St. Louis, Missouri, with 25+ office and production locations across the Americas, EMEAI, and Asia Pacific, including a catalyst manufacturing plant in Martinez, California, regional headquarters in Shanghai and Hoeilaart (Belgium), and satellite offices spanning six continents.

Elessent generates revenue through four primary streams: technology licensing (process design and know-how fees for MECS, STRATCO, BELCO, and IsoTherming), equipment and catalyst sales (proprietary catalysts, mist eliminators, acid coolers, heat exchangers), engineering and technical services (including operator training via TMODS-based simulators), and digital solutions (the MECS Digital Advisor subscription platform). The go-to-market combines direct enterprise field sales with regional VPs covering Americas, EMEAI, and Asia Pacific, a global network of joint ventures and licensees, and partnerships with engineering procurement and construction firms. Customers are large industrial enterprises including PetroChina, Ma'aden, Ivanhoe Mines' Kamoa-Kakula, Jiangxi Copper, First Quantum Minerals, Next Wave Energy Partners, and Essar Oil UK.
