High velocity thermal spray achieves 50 savings in renewables conversion

摘要

A former refinery in Eastern Canada was carrying out a site-wide conversion in preparation for the use of renewable fuels instead of oil.The Canadian government was partly financing this conversion,and the refinery aims to start processing sustainable aviation fuel(SAF)this summer,which can result in an up to 80 reduction in carbon emissions compared to the traditional jet fuel it replaces.Two reactors and two drums required an internal metallurgy upgrade due to the new operating conditions,as with renewables processing,reactors are susceptible to high temperature free fatty acid corrosion,sulfidation,wet chloride corrosion,and stress corrosion cracking.This upgrading could be achieved by automated welding,or high velocity thermal spray(HVTS).
