Chevron Lummus unveils new ISOTERRA process for SAF production

In California, Chevron Lummus Global LLC announced the expansion of its technology portfolio with the addition of its new ISOTERRA process for renewable diesel and sustainable aviation fuel (SAF) from biomass sources. The two-step process involves hydrodeoxygenation of alternative feeds such as vegetable, algae, palm and used cooking oils. It is then followed by dewaxing to meet final cold flow property specifications.

ISOTERRA helps repurpose existing assets, making it ideal for revamping existing hydrotreaters to renewables service as the process can be implemented in either one or two reactor stages. The two-stage configuration allows feed and product flexibility and robustness, and the single-stage configuration provides a low CAPEX option for existing hydrotreating facilities.
