Introduction - choose your path to SAF scale Whether you retrofit an existing hydrotreater for co-processing or design a greenfield SAF complex, BioFlux™ TPT integrates smoothly using standard refinery equipment. Modular supply compresses schedules, enabling ≤24 months from concept to modules. Integration options 1) Retrofit + coprocessing Leverage the existing hydrotreater to co-process bio-feeds. BioFlux™ prepares FOGs so you can ramp production quickly while validating hyd

Introduction - turning “problem” FOGs into opportunity High-impurity waste fats and oils are abundant and cheap, but they challenge conventional pretreatment. BioFlux™ converts and cleans these feeds into hydrotreating-ready material while minimizing contaminants and oxygen content - allowing refiners to reliably monetize hardest-to-use streams, including Category 1 tallow. What feedstocks are in scope? Used Cooking Oil (UCO) Distillers Corn Oil (DCO) Soybean oil and palm oil

Introduction - the business case for thermal pretreatment BioFlux™ improves both OPEX and product margins by tackling the two biggest SAF cost drivers: feedstock price and hydrogen consumption. It enables use of lower-cost FOGs and reduces hydrotreating hydrogen demand by up to 50% through oxygen removal. Combined benefits translate to up to 12% lower production costs vs. conventional processes, and up to 15% savings when compared to the combined conventional pretreatment + h

Introduction - from triglycerides to hydrotreating-ready feed FOGs are chemically complex. Conventional pretreatment struggles to make them uniform enough for hydrotreaters especially when metals, phosphorus, and chlorides are high. BioFlux™ TPT thermally converts these feeds: triglycerides become free fatty acids (FFAs) and PIONAs, contaminants are radically reduced, and oxygen is substantially removed before hydrotreating. Core mechanism - thermal cracking with purpose Trig

Introduction - the fast lane to competitive SAF Sustainable aviation fuel (SAF) economics hinge on two variables: feedstock cost and hydrotreating efficiency. Sulzer’s BioFlux™ Thermal Pretreatment Technology (TPT) unlocks low-cost feedstocks including used cooking oil (UCO), distillers corn oil (DCO), and Category 1 tallow by drastically lowering contaminants (up to 96% metals, 99% phosphorus, 99.9% chlorides) and removing up to 50% oxygen before hydrotreating. The result is

As the world races to meet ambitious emission targets, the demand for clean fuels from renewable sources is surging. Renewable diesel also known as hydrotreated vegetable oil (HVO) - has emerged as a leading alternative for road transportation, while sustainable aviation fuel (SAF) production increasingly relies on hydrotreated esters and fatty acids (HEFA). Both pathways utilize hydroprocessing technologies to convert fats, oils, and greases (FOG) into high-quality, drop-in

Introduction As the renewable fuels industry grows, the shift from traditional fossil-based feedstocks to fats, oils, and greases (FOG) brings new challenges - chief among them, managing contaminants. The choice of pretreatment technology is critical, as it directly impacts downstream processing, product quality, and operational efficiency.
