Screening of site-wide retrofit options for the minimization of CO2 emissions in process industries

초록

This paper addresses the systematic screening of possible retrofit options for the minimization of CO2 emissions from process industries. In retrofit scenarios there are various options for the reduction of CO2 emitted which can be considered with different costs and capacities for CO2 reduction/removal. This study considers a holistic view accounting for multiple sources of CO2 emitted from a site and multiple potential retrofit options which can be implemented individually or in combination to meet CO2 reduction targets. For a given site the different possible retrofit options are ranked in terms of costeffectiveness and the most appropriate options are highlighted using graphical methods to suggest the most cost-effective combinations of retrofits. A case study is used to demonstrate the applicability of the proposed design methodology. This case study illustrates how fuel switching and energy-saving projects can be practical and beneficial measures for the implementation of decarbonization in process industries.
