Abstract
A chemical plant or a petrochemical plant or a refinery may include one or more pieces of equipment that process one or more input chemicals to create one or more products. For example, catalytic dehydrogenation can be used to convert paraffins to the corresponding olefin. A delta temperature controller may determine and control differential temperature across the reactor, and use a delta temperature to control a set point for a heater temperature controller. By doing so, the plant may ramp up a catalytic dehydrogenation unit faster and ensure it does not coke up the catalyst and/or foul a screens too quickly. Catalyst activity may be taken into account and allow the plant to have better control over production and run length of the unit.
