Abstract
As anthropomorphic levels of carbon dioxide continue to rise, it is necessary to implement responsible production practices to minimize the greenhouse gas created in industrial processes. One such process of interest is that of shale gas, which is expected to increase in production and become our dominant natural gas source within the next few decades. Currently, carbon dioxide sequestration techniques like enhanced oil recovery (EOR) and geological sequestration have helped alleviate some of the burden. However, these methods only serve to store limited amounts of CO2 and do not reduce the overall global net levels.
In this study, the utilization method of mineralization is investigated as a potential integrated process to turn CO2 into value added products. Furthermore, the use of industrial waste as a mineral feedstock is implemented to facilitate sustainability practices. Through Aspen modeling and simulation, the integrated process can be evaluated for several waste sources and the overall economics can be analyzed to determine financial viability.
Results indicate that over a large range of waste compositions the process could return a considerable profit over a relatively short time span. Cost sensitivity analysis also demonstrated the systems flexibility for fluctuations in product price points. The results of this study will hopefully encourage further look into CO2 utilization methods as not only an environmentally oriented practice, but as a profitable and sustainable option.
