Abstract
AbstractA mathematical model of the transient behavior of an existing ethane dehydrogenation furnace is discussed. The correlation of pressure drop with time has been found from the available data. The fractional carbon deposition and the multiplier coefficient of a pressure drop equation have been determined by the direct search optimization technique of Hooke and Jeeves.A considerably improved policy for the operation of the furnace was determined by considering plant temperature profile and hydrocarbon/steam ratio as parameters for maximizing average ethylene produced per day. The effect of temperature profile on the distribution of carbon deposited along the reactor was also predicted and discussed.
