Advanced process control in a continuous catalytic regeneration reformer

An advanced process control system in a continuous catalytic regeneration reformer for maintaining heavy reformate octane number and maximizing heavy reformate octane barrel while controlling coke on spent catalyst, said system comprising:

• a master-slave configuration, comprising:
• a master advanced process controller configured to:
• predict coke on spent-catalyst based on an online inferential;
• an empirical tool;
• and
• specify a set point for at least one of:
• a) hydrogen to hydrocarbon (H2/HC) ratio in respect of a reaction-section, and b) catalyst circulation rate in respect of a regeneration-section;
• a reactor advanced process controller to at-least optimize a control ratio of H2/HC within the reaction-section based on the set point specified by the master advance process controller;
• and
• a regenerator advanced process controller to at-least optimize the catalyst circulation rate within the regeneration-section based on the set point specified by the master advance process controller;
• wherein, the reactor advanced process controller and the regenerator advanced process controller are linked to the master controller.
