Fluor's scope includes feasibility, FEED and detailed engineering for the inside battery limits (ISBL) facilities. Fluor is acting as agent for the client in procuring all ISBL materials, services and equipment. Fluor also performed the pre-FEED studies for the hydrogen plant.
Two existing refinery units will be revamped to produce R100 diesel, a distillate hydrotreater (DHT) and a naphtha hydrotreater (NHT). The combined units are referred to as the renewable diesel unit (RDU). The DHT converts the soybean oil to n-paraffins via olefin saturation and hydrodeoxygenation, while the NHT isomerizes the n-paraffins in a sweet catalyst environment to improve cold flow properties. Some equipment from other units will also be integrated into the RDU.
The client and Fluor aligned early on the optimal balance between schedule reduction, quality requirements and capital investment. Developing high-quality deliverables that could be adapted for late changes was deemed the best approach to support safe and efficient construction while maintaining the accelerated schedule and supporting the client’s economic model.
