The multiperiod blending problem involves binary variables and bilinear terms, yielding a nonconvex MINLP. In this work we present two major contributions for the global solution of the problem. The first one is an alternative formulation of the problem. This formulation makes use of redundant constraints that improve the MILP relaxation of the MINLP. The(More)
In the optimization of liquid production from power-intensive Air Separation Units (ASU’s), decisions need to be made at two time scales week-ahead production scheduling to leverage fluctuations in electricity prices, and real-time decisions that optimize the entire plant operation, while capturing spot opportunities. Although methodologies exist for(More)
