the Raychem Skin-effect Tracing System (STS) because the bundled longline technologies would optimise the heat management system performance: • Pre-insulated/pre-fabricated piping systems that offer superior thermal insulation reliability and underground integrity by providing a homogeneous temperature profile for the entire length of the pipeline. • Fiber-optic Distributed Temperature Sensing (DTS) systems to measure the temperature of the underground pipeline every metre along its underground routing. • Raychem Pipeline Supervisor (RPS) predictive analytics software for comprehensive control and to safely manage temperature-critical pipelines. • Power distribution solution at one end of the pipeline. Process temperature maintenance of this key feedstock line was completed using directional drilling to install a one-mile-long, pre-insulated, STS-heated, underground pipeline with the temperature being maintained at 120°F (50°C). The pipeline temperature is being monitored every metre along this pipeline using DTS-Fiber Optic. RPS ensures feedstock flow assurance by monitoring the entire pipeline and providing the data required by operations to ensure this underground line is functioning as designed. Case study 5: Self-regulating heating cable technology in CCS industry Ethanol plants in the Midwest USA produce significant CO₂ as a result of fermentation. With an overall goal of protecting the long-term viability of the ethanol and agricultural industry, a Midwest customer is partnering with more than 30 ethanol plants across five states on a project to reduce the carbon emissions at each location through a CCS process. At each ethanol facility, CO₂ will be captured, dehydrated, and compressed, and then CO₂ will be gathered and transported through pipelines to the deep geological formation injection point in North Dakota. The customer’s mission-critical objectives for the heat management solution include ensuring operational reliability for managing northern climate freeze protection and process temperature maintenance and optimising energy efficiency across all the plants. This CCS project is currently the largest in the

world and upon completion will safely capture 18 million metric tons of CO₂ per year. nVent engineers designed a system using Raychem XTVR high-temperature self-regulating heating cables with High Power Retention (HPR) technology for both the process temperature maintenance and freeze protection applications. The design was completed with the advanced Raychem NGC-30 heat trace control and monitoring unit to save energy, minimise risk, and maximise productivity. Case study 6: Self-regulating heating cable technology in hydrogen industry A leading global producer of industrial gases in Alabama is constructing a new SMR hydrogen plant to support the long-term viability of the chemical industries in the area. The facility design and construction include all the infrastructure and utilities required for an industrial project. The customer’s mission-critical objectives for the heat management solution include finding the optimal system design that would keep critical process maintenance and freeze protection applications running, prevent condensation in large bore piping that transports process gases and nitrogen gas, protect/winterise instruments, and provide an energy-efficient control and monitoring solution that verifies the operational reliability of the heat management system. nVent engineers designed a system using Raychem XTVR high-temperature self-regulating heating cables with HPR technology for both the process temperature maintenance and freeze protection applications. The design was completed with the NGC-40 heat trace control and monitoring unit to save energy, minimise risk, and maximise productivity. Summary Critical heat trace solutions for the energy transition industries will remain vital as more industrial facilities convert to clean fuels and CO₂ reduction. Securing reliable operation and uptime in plants and refineries, especially with the high-temperature maintain demands of new biofuel feedstocks, will require well-designed solutions to manage pipe, tank, and equipment temperatures. nvent.com/RAYCHEM
