Optimization Olefin-Paraffin operating condition through membrane /distillation hybrid system

Light olefin and paraffin are commonly separated by cryogenic distillation which is extremely energy intensive. Membrane/distillation hybrid system is an economical alternative separation process in this regard. In this paper, augmenting a membrane module in existing distillation column is investigated. Different hybrid configurations named: top, bottom, front and parallel configuration system and its optimum parameters are included in the survey. Results show that the most beneficial configuration is parallel which will result up to 45% reduction in reflux ration and therefore about 50% energy saving
