This paper presents the application of a MVCA technique for the prediction of C3 concentration in the outlet stream of the deethanizer tower (outlet stream of a liquefied gas natural plant). This is a variable whose prediction and inference is of great importance in the correct control of the unit. Good results are obtained with a non parametric MISO (Multiple Input Single Output) model (impulse response) provided by the multivariable correlation technique using real data from a commercial plant. This paper also suggests a procedure to handle output data whose sampling rate is lower than input sampling.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-10-11T13:33:52Z No. of bitstreams: 1 1-s2.0-S0920410509000369-main.pdf: 802619 bytes, checksum: acb0cf7e64defa01e5e0e3c326afca96 (MD5)Approved for entry into archive by LIVIA FREITAS(livia.freitas@ufba.br) on 2013-10-16T15:03:01Z (GMT) No. of bitstreams: 1 1-s2.0-S0920410509000369-main.pdf: 802619 bytes, checksum: acb0cf7e64defa01e5e0e3c326afca96 (MD5)Made available in DSpace on 2013-10-16T15:03:01Z (GMT).
