“…The selection of separation-systems process synthesis is motivated by the high capital costs and energy consumptions of these systems (Agrawal, 2001). Most discussion in this section may be extended to process synthesis of other systems.…”

a b s t r a c tThis paper gives the author's perspective on some of the open questions and opportunities in process synthesis focusing on separation systems as the application. Driven by energy and environmental concerns and challenged by introduction of new raw materials, this author anticipates significant advances in: (1) novel approaches that integrate experimental studies and process synthesis activities, and multiscale and surrogate models for accurately capturing the behavior of these unconventional mixtures, (2) systematic generation of alternatives for processing these mixtures, and (3) global, robust, and stochastic optimization for identifying the optimum alternative. This paper is an extended version of a conference

“…Since the advent of synthetic zeolites in 1950s and pressure swing Adsorption (PSA) processes in 1970s the small and medium scale air separations are being increasingly accomplished by adsorption. PSA air separation has become more economical at product throughputs below 10,000 standard cubic meters per hour compared to cryogenic distillation (Agrawal, 2001). Now, about one-fifth of air separation is carried out using adsorption technologies, i.e., PSA and vacuum swing adsorption (VSA) (Rege and Yang, 1997).…”

“…As CO2 emissions are directly related to the energy consumption, more energy efficient distillation also contribute directly to reduction in CO2 emissions. In addition, more energy efficient configurations that reduce the internal vapour and liquid flow rates give more compact units with a smaller diameter and thus reduce the capital cost (Agrawal, 2001).…”
