Abstract

“This thesis contains some of the results of the work involved in developing an optimal equipment configuration for ethylene recovery. A comparison is made (using a simulator) between a conventional design that uses a front end demethanizer with ethylene and propylene refrigerants and a revised design that uses distributed distillation. The material and energy balances for both designs together with their associated refrigeration systems are calculated The two designs are heat integrated after analyzing the appropriate composite heating and cooling curves. The thermodynamic efficiencies within the distillation columns are analyzed. In order to pinpoint the process improvements comparisons are made on three different bases; firstly, including all equipment after the third stage of compression; secondly, including al equipment after the third stage of compression, but excluding the depropanizer and all equipment downstream of the depropanizer; lastly, the effect of thermomechanical integration of the propane/propylene splitter is evaluated.

Process flow diagrams, heating and cooling curves, equipment lists and utility summaries are generated. A comparison is made between the designs based on thermodynamic efficiency and purchased equipment cost.

Areas for new improvement are identified and commented on”--Abstract, page iii.
