Operation of homogeneous azeotropic distillation column sequences

  title={Operation of homogeneous azeotropic distillation column sequences},
  author={Jan Ulrich and Manfred Morari},
A self-optimizing control concept is provided for sequences of three homogeneous azeotropic distillation columns with two recycles separating a ternary feed of a 020 mixture that has two simple distillation regions that are separated by a residue curve boundary. Studying a case with reduced complexity (columns of infinite length operated at infinite reflux), one of the two recycles (the entrainer recycle) is identified as the key manipulated variable for ensuring optimal operation of the… CONTINUE READING
