What about reactor advanced process control?

摘要

The premise of advanced process control(APC)is that there is money to be made by pushing a unit against its limits while keeping the product qualities at target.This concept is easy to understand but difficult to implement because,while some qualities and unit constraints are measured,many are not.Expressing unmeasured process parameters in a numerical format suitable for our multivariable control tools is the challenge of our industry.Applications that can do it mine gold,and those that cannot join the high pile of APC garbage.Many papers have already been devoted to inferential modeling of product qualities and,hence,this editorial concentrates mostly on other unmeasured constraints.
