Introduction

The world is shifting towards a more sustainable and environmentally friendly energy source, and one of the promising alternatives is green diesel. Green diesel is a diesel fuel produced from the hydrogenation of vegetable oil, which has several advantages over fossil-based biodiesel and fatty acid methyl ester (FAME). In this article, we will discuss the prancangan (design) of a factory that produces green diesel from Palm Fatty Acid Distillate (PFAD) with a production capacity of 100,000 tons per year.

Advantages of Green Diesel

Green diesel has several advantages over traditional diesel fuel. Firstly, it has a higher cetane number, which ranges from 55-90, making it a cleaner-burning fuel. Additionally, green diesel has a lower sulfur content, which reduces air pollution and has a positive impact on the environment. It also has good oxygen stability and a clearer color, making it a more desirable fuel for consumers.

Production Process

The production process of green diesel involves catalytic hydroprocess and hydrodeoxygenation reactions. These reactions are in accordance with the characteristics of PFAD raw materials, which are rich in fatty acids and are included in the category of non-food vegetable oils. The hydrodeoxygenation reactor is a key component in the green diesel production process, and it is designed to be highly efficient in converting PFAD into a quality green diesel.

Hydrodeoxygenation Reactor Design

The hydrodeoxygenation reactor is designed to be a Fixed Bed Multitube Reactor, with a catalyst of Palladium in Gamma Alumina (PD/γ-al2O3). The reactor has a total mass of 631,307 kg and is constructed from SA-299 carbon steel. It has 39 tubes, each with a thickness of 1 1/4 inch, and a shell diameter of 60 inches with a thickness of 3/4 inch. The reactor height is 10,940 m, making it a large and complex piece of equipment.

Factory Economic Analysis

The economic analysis of the green diesel manufacturing factory from PFAD shows that it is feasible to be established. The total investment capital required is Rp 3,231,081,337,588,53, while the total production costs are Rp 1,086,487,515,642.47. The sales revenue is expected to be Rp 2,095,934,457,983.03, resulting in a net profit of Rp 671,528,691,103.97. The profit margin is 45.767%, while the break point (BEP) is 23.246%. The investment return (ROI) is 20.794%, and the return time (pot) is 4 years 11 months. The network returns (RON) are 34,657%, and the internal return rate (IRR) is 26.913%.

Conclusion

The establishment of the green diesel manufacturing factory from PFAD with the addition of the isomerization process is a strategic step in the development of sustainable energy sources. In addition to meeting environmentally friendly energy needs, this factory also has the potential to provide economic benefits for the community and the surrounding area. With the support of appropriate technology and efficient management, this factory is expected to contribute to the optimal and sustainable use of vegetable resources.
