Abstract

Large quantities of energy are required in distillation of light olefms such as ethylene used for polymer grade separations of close boiling mixtures. Since the ethylene/ethane separation is the more difficult separation in terms of energy and requirement, it also provides greater opportunity for altering the economics of the ethylene process. The purpose of this paper is to introduce an industrially viable; internally heat integrated DISTILLATION COLUMN (HIDiC) version of a state of art C2 SPLITTER by using a HEAT PUMP assisted, stand-alone column. In this article, a methodology is proposed for the thermal integration of electrically driven HEAT PUMPing systems between intermediate stages in DISTILLATION COLUMN using the concept of Column Grand Composite Curve (CGCC). To accomplish this goal, Equation Oriented (EO) modular of Aspen plus is applied. This research differs to other's work in term of HEAT PENALTY that causes more utility load and hydraulic bottlenecking in a column. An objective function consisting of utility costs and product revenue is established to maximize the net profit obtained from this process. A sensitivity analysis is executed over different electricity and capital cost scenarios. Eventually, the most competing scenarios in term of total annual profit are determined.
