Global Technology & Engineering
Applying established process technologies and engineering expertise to refining, gas processing and energy infrastructure.
Process Technology
Fourier has a strong track record of engineering and optimizing Honeywell UOP technology routes for commercial refining operations, spanning hydrotreating, hydrocracking, gasoline upgrading and jet fuel treating.
We have directly supported projects utilizing Unicracking and Unionfining for distillate production, Platforming and Penex for gasoline upgrading, and Merox for fuel treating, ensuring seamless design integration from feedstock analysis to final product.
Technology & Engineering
Fourier provides comprehensive engineering and brownfield/greenfield integration for KBR process technologies, executing refining and petrochemical studies for residue upgrading and olefins production.
Our team's project expertise covers ROSE solvent deasphalting, SCORE selective cracking, K-COT catalytic olefins technology and K-PRO propane dehydrogenation, unlocking reliable pathways to higher-value fuels and chemical feedstocks.


Separation & Mass Transfer
Fourier partners with operators to deploy Sulzer Chemtech technologies, executing detailed separation-system designs for distillation, absorption and gas–liquid separation in refining and gas processing.
We have successfully implemented Mellapak and MellapakPlus structured packing, column trays, internals and mist elimination systems to achieve column efficiency, capacity upgrades and lower pressure drop in grassroots installations and turnaround revamps.
Refining & Clean Fuels
Fourier brings hands-on engineering expertise in Axens technology routes, catalysts and adsorbents, delivering process design and optimization for hydrotreating, hydrocracking, catalytic reforming and residue upgrading.
We have worked directly with key platforms including Prime-G+ for FCC gasoline desulfurization and H-Oil for residue hydroconversion, enabling refineries to meet strict clean-fuel mandates and maximize heavy-residue margins.
