摘要

Utilization of fossil fuel, as one of the major contributorsrnin CO_2 emission production, provides driving forcernbehind global warming. Increasing energy efficiencyrnthrough energy retrofit of process plants can reduce fuelrnrequirement and hence reduce CO_2 emission production.rnThe current practice for reducing CO_2 emissions oftenrnselects the retrofit options with no consideration of carbonrntax or opportunity for carbon emission credit. This workrnpresents a design methodology to select and combinernfrom the heat exchanger network (HEN) retrofit optionsrnof different process plants considering the availablerninvestment cost for process integration measures andrnconstraining carbon emission reduction target. Thernpresented methodology investigates the capability of thernintroduced scenarios from combined retrofit options forrncarbon emission credit opportunity. In this method therndecision for degree of heat recovery in retrofit of HENrncan be made either based on achieving maximumrnopportunity for carbon emission credit considering fixedrnavailable investment cost or based on investing minimumrncost to maintain the emission reduction target with nornextra CO_2 emission reduction. The final decision makingrnis then based on total payback of the combined retrofitrnscenario. The method is developed through a case study.rnResults show that the presented method is capable torninclude issues of carbon emission trading scheme inrnmaking decision for energy conservation in processrnindustries with the objective of reducing CO_2 Emission.rnThe results also illustrate that the payback of therncombined retrofit options which are selected to meet thernemission target are lower and hence better options relativernto those that provide CO_2 emission credit.
