Figure 6 Raychem Pipeline Supervisor DTS fibre optic technology captures data points along the entire length of the pipeline
• Pre-insulated/prefabricated piping systems that offer superior thermal insulation reliability and underground integrity by providing a homogeneous temperature profile for the entire length of the pipeline. • Fibre optic DTS to measure the temperature of the underground pipeline every metre along its underground routing. • Raychem RPS predictive analytics software for comprehensive control and safe management of temperature-critical pipelines. This key feedstock line was constructed using mostly horizontal directional drilling to install the 1.6 km, pre-insulated, STS heated underground. The pipeline temperature is monitored every metre along its length using DTS fibre optic technology (see Figure 6 ). Raychem RPS software ensures feedstock flow assurance by monitoring the entire pipeline and providing the real-time data required for operations to confirm that this underground line is functioning as designed. Conclusion This case study highlights the challenges the renewable diesel industry faces, not only in processing new feedstocks but also in transporting them to refineries. The energy transition has brought significant attention to biofuels, including biodiesel, renewable diesel, and sustainable aviation fuel (SAF), all
of which use similar feedstocks. This creates new challenges for maintaining process temperatures, regardless of delivery methods. New renewable diesel refineries will integrate HMS into their feedstock handling areas. Retrofitted refineries will need to add HMS to manage feedstocks in areas lacking heat tracing or thermal insulation and may face power “ Retrofitted refineries will need to add a heat management system to manage feedstocks in areas lacking heat tracing distribution challenges. We strongly recommend involving a heat management integrator early in the design process for both new and retrofit renewable diesel projects to ensure the most reliable feedstock HMS possible. or thermal insulation and may face power distribution challenges ”
