Best options for a reboiler revamp
It is always a challenge to reconfigure and resize existing reboilers, especially vertical thermosiphon ones, for the revised design and operating conditions of a brownfield project, since hydraulics external to the reboiler must match the reboiler hydraulics under the revamped conditions to ensure trouble-free operation.
An evolving approach to digitalization
Much has been written in recent years about the need for refineries to embrace the Industrial Internet of Things (IIoT).
