Through the use of this statistical tool, together with a detailed deterministic model validated with industrial data, it is possible to identify the most relevant variables to be considered as degrees of freedom for the optimization and also to acquire significant process knowledge, which is valuable not only for future explicit optimization but also for current operational practice. The responses evaluated by the experimental design approach include the objective function and the constraints of the optimization, which also consider the polymer properties. A Plackett-Burman design with 16 trials is first carried out in order to identify the most important inlet variables. This reduces the number of decision variables, hence the complexity of the optimization model. In order to carry out a deeper investigation of the process, complete factorial designs are further implemented. They provide valuable process knowledge because interaction effects, including highly non-linear interactions between the variables, are treated methodically and are easily observed.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-08-24T23:01:51Z No. of bitstreams: 1 a15v28n1.pdf: 1830894 bytes, checksum: 784abd543b78bf8091d0d3a313a84c07 (MD5)Made available in DSpace on 2011-08-24T23:01:52Z (GMT).
