Abstract: In this paper, the application of RMPCT controllers of Honeywell company in Gas
Rectification Unit in a refinery is introduced . The control strategies and adaptive model are also described. By using theoretical fractionator model and soft sensor software of CUP, we havesuccessfully implemented advanced process control for gas rectification unit . We also developed the software to realtime modify the RMPCT controller model according to the process. So that, model adaptation is also realized. Current commission result indicates that it can stablize the operation of unit , optimize the operation online ,ensure the quality more stable and achieve significant economy benefits.
