Two Key Features
Benefits in Operation
EST does not have to be used for all the tubes in the furnace. The application of EST only to the hottest sections of the furnace (most severe coking) has been proven to be effective and thus the initial cost penalty can be reduced. EST can contribute to maintenance cost reduction and productivity growth.
