13.5.1** Develop a computed MV controller for the reboiler shown in Figure 13.5.1, assuming that steam is used for reboiler duty instead of quench water. The computed MV controller should be able to make adjustments in the steam flow rate to account for changes in the steam enthalpy; therefore, the steam temperature and pressure upstream of the control valve should be measured and used by the computed MV. Assume that there is no condensed water in the steam. 124 Team Computed Reboiler Controller Qxpec AC TT RSP FCK TT FT) Quench Water 1.
