DESCRIPTION:Paper making is a very energy-intensive operation. In recent t
 imes\, increasing interest in the environment and significant rises in ene
 rgy costs have generated considerable interest in finding ways to improve 
 the energy efficiency of paper-making. By reference to work undertaken on 
 several full scale commercial machines\, the seminar will discuss some sig
 nificant progress made in this direction using multivariable Advanced Proc
 ess Control (APC).  A paper machine is an adventurous and complex conjunct
 ion of mechanical\, chemical and electrical phenomena. It is a very multiv
 ariable process and yet it is typically controlled using traditional singl
 e loop control strategies which are not naturally suited to comprehending 
 and compensating for the effect a number of input variables may have on ea
 ch paper quality variable. Consequently\, in normal operation many potenti
 ally useful control variables remain unused. Furthermore\, efficient opera
 tion of a paper machine requires a control system able to optimize in real
 -time. APC has the capability to provide control that meets both these req
 uirements. The seminar will explain the potential for energy saving in pap
 er making which APC offers. Present indications are that at least a 20% re
 duction may be possible.
