At one of the most modern and complex refineries in Asia (11+ Nelson complexity index) they have decided to apply Tubacoat technology in their Delayed Coker Unit, which is one of the 3 largest worldwide. Tubacoat internal coated tubes were successfully installed in October 2020 in of one of their furnaces. Cost savings, increased reliability and improved heat transfer efficiency are the factors which motivated their decision.
Coating of the whole radiant section is expected to save the refinery over 10 million USD/year, based on the reduced number of decoking shutdowns needed and increased throughput.
With this project Tubacoat expands its reference list for fired heater anti-coking applications, which include Vacuum Distillation Units, Visbreakers and Delayed Cokers.
