Methods for Optimizing Petrochemical Facilities Through Stream Lined Transferal

Methods and processes for moving towards optimizing one or more parameters in a parallel train comprising two hydrocarbon cracking facilities where the two facilities either have non-identical process unit configurations or are operating under non-identical process conditions are disclosed. These methods and processes use models to simulate the impact of interconnecting the facilities by partially withdrawing an intermediate stream from within one cracking facility and adding the partially withdrawn stream to the second cracking facility in order to better optimize the overall operation of the parallel train.
