Conceptual Design of an Integrated Process IncludingHeat and Mass Exchange Networksand Renewable Energy

Many process industries include complex networks of mass and heat transfer units. Although theseunits are separately considered during the design and optimization stages, they have some interactionsthat affect overall performance; therefore, considering these interactions is critical to find an optimaland practical design. The aim of this research is to use a conceptual method to design a processincluding mass and heat exchange networks emphasizing the application of renewable energy inchemical industries. For this purpose, the process of removing ammonia from the ammonia-rich gaseousstreams using a water-based solvent as mass separating agent (MSA) and then regeneration of theammonia-rich external MSA stream with steam stripping was investigated. In comparison with resultsof a mathematical method, the consumption of solvent reduced by about ۶۷% while the number of massexchange units remained the same, resulting in a ۲۰% reduction of the total annualized cost.
