Abstract
Systems and methods for separating a multi-component fluid are provided. The method can include introducing a multi-component fluid to a dividing wall column. The multi-component fluid can be heated to provide a first product, a second product, an intermediate distillate, and a process fluid. At least a portion of the first product can be compressed to provide a compressed first product. Heat can be indirectly transferred from the compressed first product to at least a portion of the intermediate distillate to provide a heated intermediate distillate. The heated intermediate distillate can be recycled to the dividing wall column. The compressed first product can be expanded.
