An evaluation of shale gas reforming technologies—Part 2: Cost and carbon intensity estimation

Part 1 of this two-part article explored the different types of methane reforming technologies and explained the characteristics of each. Part 1 also presented a selection methodology that can be used to screen the different reforming pathways at the early stages of the project definition. In Part 2, an order-of-magnitude cost correlations carbon-footprint estimation is provided that can guide designers in making preliminary design decisions for a process that involves a reformer. A linear regression of data from gas-to-liquid (GTL), ammonia and methanol plants was used to develop the correlations using simple inputs of the natural gas feed capacity and the desired (H2/CO) ratio. The devel
