Decarbonisation Technology - November 2023 Issue

processes in these facilities through a few different technologies, with the most common one today being regenerant amine absorption. The CO₂ is then dehydrated, compressed, and typically piped to an underground storage facility. Higher temperature SR heat management applications are typically associated with the steam system, the regenerant amine system, the dehy unit, and the lube oil systems in these facilities. The biofuels industry

nVent’s high-temperature SR heating cables with innovative High Power Retention (HPR) technology

of rated performance even after 10 years of operation at continuous exposure to maximum temperatures, and a heating cable design life of 30+ years. Plus, with more available power variants (XTVR has seven at 200-277V and four at 100-130V; HTV has eight at 200-277V), a more efficient heat-trace design that closely matches the heat loss of industrial process pipes is now possible. This, in turn, helps with cost savings on energy consumption and power infrastructure, and reduces downtime risk and maintenance costs for decades. High-temperature self-regulating cables with HPR are a perfect solution for energy transition industries. Not only is this novel technology ready to keep critical processes operational, protect pipes, tanks, and equipment from freezing, and meet the maintenance demands of new biofuel feedstocks, but it also helps us create a more sustainable future.

includes ethanol, biodiesel, renewable diesel and sustainable aviation fuel (SAF). The feedstocks include plant oils, animal fats, and used cooking oils, which often require process maintenance temperatures in the 50°C/122°F range. Biodiesel as an end product requires a similar process temperature maintenance. This requirement impacts the (un)loading and storage facilities of feedstock and the end product. nVent recently developed high-temperature SR heating cables with innovative High Power Retention (HPR) technology: • Raychem XTVR heating cables are designed for continuous operating temperatures up to 302°F (150°C) and withstand temperatures up to 482°F (250°C). • Raychem HTV heating cables are designed for high continuous operating temperatures of 205°C/400°F and withstand temperatures up to 260°C/500°F. The power retention levels for both XTVR and HTV cables surpass previous self-regulating heating cables in performance and design life. These cables guarantee a minimum of 95%
