We are installing a coking unit, and we found that there are three radial feed pumps from the distillation tower to the coking furnace; one of these pumps is powered by steam, while the other two are powered by motors. So why not use motors as power sources for all three pumps? What is the purpose of using a steam pump in one of these units?

It is designed in this way to prevent a disruption in the material flow to the coking furnace due to sudden power outages, or a disruption in the feeding of the coking furnace as a result of a stoppage in steam supply driven by steam pumps.
