(500c) Process Design Frameworks for Cost-Effective Small-Scale Processes
In this work, we propose new design targets for small-scale technologies which are significantly less capitally-intensive compared to current designs. To this end, we develop three different methodologies which can work in tandem for achieving the proposed design targets for reducing overall capital intensity [1,2]. The methodologies are as follows: (i) functionality-based concurrent design, (ii) dynamic process intensification and (iii) agile and flexible chemical productions. The functionality-based concurrent design methodology departs from traditional design of individual plants in isolation, and instead incorporates simultaneous design and manufacturing of multiple small-scale processes. From manufacturing standpoint, simultaneous design is advantageous as economies of numbers can be leveraged via standardized equipment design for multiple processes. Secondly, we use the reaction-adsorption principles rooted in dynamic process intensification to obtain more compact, efficient, cost-effective and sustainable intensified processes. Lastly, we use flexible manufacturing processing trains to leverage temporal variabilities typical in feedstock availability and quality; and product demand and price. The advantages offered by the proposed design protocols are demonstrated through a variety of case studies fundamental to midstream- and downstream-processing of unconventional natural gas.
