This blog was originally posted on Hydrocarbon Processing and is a follow-up article to “Automate furnace controls to improve safety and energy efficiency,” which was published in the June 2014 edition of Hydrocarbon Processing. That earlier article described how automatic controls could be used in furnaces to enhance both safety and efficiency at the basic process control system (BPCS) level.
