GRADE TRANSITION CONTROL FOR AN IMPACT COPOLYMERIZATION REACTOR

摘要: Abstract In impact polypropylene processes, two reactors in scries are usually employed. The first reactor makes propylene homopolymer (HP), while the second ethylene-propylene rubber (EPR). industry, products of different grades must be made same train, so efficient and safe grade transitions essential. This paper describes both method for determining optimal transition trajectory use model-based control implementing this transition.
