HVO/SAF Hydroprocessing Pilot Plant

Description

The HVO/SAF Hydroprocessing Pilot Plant is a modular pilot-scale unit that converts biobased feedstocks into Sustainable Aviation Fuel via catalytic hydrodeoxygenation and isomerization reactions of the Hydrotreated Vegetable Oil (HVO) process, under representative pressure and temperature conditions. It integrates two fixed-bed reactors for Hydrodeoxygenation (HDO) and Isomerization (ISOM), operating up to 500 °C and 150 barg with multi-zone electrical furnaces ensuring precise temperature control. The plant features heated and nitrogen-blanketed liquid feed systems, high-pressure hydrogen and nitrogen supply with mass flow control, and a hydrogen recirculation loop via a dedicated compressor. Advanced gas conditioning and preheating sections ensure stable reactor operation. Multi-stage high- and low-pressure separation systems enable efficient gas, organic, and aqueous phase recovery. Product flows are accurately quantified using Coriolis flow meters and weight scales to ensure full mass balance closure. Fully automated with PLC and SCADA supervision, the unit is designed for unattended operation with a multi-layer safety architecture.
