Simulation of Complex and Dry Reforming of Natural Gas for Synthesis Gas Production and their Comparison

In this study, two units of production of synthesis gas has been stimulated into 2 forms of natural gas complex reforming and dry reforming. they have been examined from technical and economical views. The product from this process is synthesis gas by the unit ratio of Hydrogen and Carbon Monoxide (H2/CO =1) which isused in Arak petrochemical complex for producing 2EH. For producing this synthesis gas in 900C (reactor temperature) and 15 bar of total pressure, the ratio of feeding parts into reforming reactor for total input carbon (methane and other hydrocarbon) and Carbon dioxide gas and water vapor in representation [CH4 + equivalent carbon in other hydrocarbons: CO2: H2O] for complex reforming equals [1: 2.5: 2.15], and for dry reformingequals [1: 1: 0.33]. The Result of mentioned simulation clarifies the percentage of saving fuel gas, Electrical Energy, water and Carbon dioxide in dry reforming to complex reforming. In this study, operational conditions and costs of energy and materials are the same real costs in production unit of synthesis gas in Arak petrochemical complex. By comparing the results out of the two simulated units it is shown that the total operational costs of the current unit will decrease more than twice in case of changing to dry reforming
