In order to do that, dynamic simulations are carried out and process responses are analyzed as functions of process operating policies and flowsheet configuration, at conditions that resemble the actual operation of industrial sites. It is shown that system responses are highly nonlinear and very sensitive to disturbances of the operating conditions and that catalyst decay is of fundamental importance for proper understanding of process behavior. Results indicate that mixing conditions inside the reactor vessels exert a significant impact upon the final polymer quality and can be manipulated for in-line control of final resin properties. Finally, it is shown that the development of feed policies, based on the use of lateral feed streams, allows the simultaneous control of melt flow index, stress exponent and polymer density of the final polymer resin.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-12-09T17:23:22Z No. of bitstreams: 1 10.1002mren.200700047.pdf: 627100 bytes, checksum: 78e1d2af26bb7a5b74ec01ff5172e185 (MD5)Approved for entry into archive by LIVIA FREITAS (livia.freitas@ufba.br) on 2013-12-18T11:51:21Z (GMT) No. of bitstreams: 1 10.1002mren.200700047.pdf: 627100 bytes, checksum: 78e1d2af26bb7a5b74ec01ff5172e185 (MD5)Made available in DSpace on 2013-12-18T11:51:21Z (GMT).
