Pre-Manufacturing Factory Manufacturing Green Diesel from PFAD (Palm Fatty Acid Distillate) with a Production Capacity of 150,000 Tons/Year and Special Task of Designing Engineering Detailed Hydrodeoxygenation Reactor

In the current era of sustainability, the need for alternative energy sources is increasingly urgent. One solution that attracts attention is Green Diesel, a vegetable fuel that has physical and chemical properties similar to Petroleum Diesel. Green Diesel can be produced from Palm Fatty Acid Distillate (PFAD), which is a source of abundant vegetable fat and does not compete with food needs. The Green Diesel factory, which is planned to produce as many as 150,000 tons per year and is located in the Special Economic Zone (KEK) of Sei Mangkei, Simalungun, North Sumatra, with a factory area reaching 20,000 m², is a significant step towards achieving this goal.

Green diesel production from PFAD is carried out through catalytic hydroprocessing reactions and hydrodeoxygenation. The hydrodeoxygenation process is a key step in removing oxygen from fat compounds, producing cleaner and more efficient fuel. In this factory, the hydrodeoxygenation reactor that has been designed using the Palladium on Carbon (PD/C) catalyst with a catalyst weight of 1,390,404 kg. The reactor used is a type of multitubular fixed bed with the following specifications:

Number of tubes: 42 tubes
Shell diameter: 54 in
Reactor height: 10,864 m

This reactor is designed to provide optimal performance in the processing of PFAD to become green diesel.

The Importance of Hydrodeoxygenation Reactor Design

The design of the hydrodeoxygenation reactor is crucial in ensuring the efficient production of green diesel. The reactor's specifications, such as the number of tubes, shell diameter, and reactor height, are carefully selected to optimize the processing of PFAD. The use of a multitubular fixed bed reactor allows for a high degree of flexibility in terms of catalyst selection and reactor design. The Palladium on Carbon (PD/C) catalyst is chosen for its high activity and selectivity in the hydrodeoxygenation reaction.
