“…For this reason, acetone produced from IPA may be preferred in the pharmaceutical industry due to the strong restrictions on using solvents . Likewise, the source of the cumene oxidation process (Hock Process) is oil, while IPA can be synthesized from various sources such as oil, natural gas, or biomass . From the global energy and environmental point of view, acetone production from IPA has CO 2 mitigation benefits .…”

Acetone purification is one of the most critical stages of its production process, because a large amount of energy is required. Due to this high energy consumption, the process turns out to be not very sustainable and not friendly to the environment. In this sense, the development of intensified alternatives that minimize energy consumption in this process is of utmost importance. Besides, the safest possible processes are sought, so it is necessary that the control properties of these novel processes be studied at an early design stage. This work proposes two new intensified systems for the purification of acetone; the intensified schemes are a thermally coupled distillation system with a side rectifier and a Petlyuk arrangement. The results indicate that in this type of systems where interconnection flows are used, the magnitudes of these flows have a direct impact on energy consumption, because lower values of interconnection flows as in the case of the thermally coupled system achieve a reduction, whereas higher values as in the case of the Petlyuk system have a negative impact. As for the control properties, the intensified schemes present better values of the condition number with respect to the conventional design, because the interconnection flows reduce the disturbance of the manipulable variables. On the other hand, if the feed is disturbed, the interconnection flows generate an increase in the disturbance in the system, obtaining that the conventional system presents the best values. Therefore, making a balance between the studied designs and looking for a system that presents the best sustainability indicators, the thermally coupled system obtains the best results with a 25.92% energy saving and CO2 emission reduction with respect to the conventional system and acceptable values for the control and safety indexes.

“…Membrane reactors can be applied to dehydrogenation of alcohols to form aldehydes or ketones in chemical syntheses [13][14][15][16][17][18][19]. Liu et al [13] performed the catalytic dehydrogenation of ethanol with a NiP-Cu composite membrane and found that both conversion and selectivity increased with an increase in the flow rate of sweep gas on the permeation side.…”

“…They also constructed a model for dehydrogenation of ethanol that could describe the reaction rate. For long chain alcohols, Trianto et al [18] conducted a study on the dehydration of 2-propanol to yield acetone with a Vycor glass-based porous membrane reactor and reported that the acetone concentration in the permeation side increased with sweep gas flow rate. Keuler and Lorenzen [19] examined the dehydrogenation of 2-butanol in a Pd-Ag membrane reactor.…”

Membrane reactors combining reaction and membrane separation provide numerous advantages over conventional reactors, including retaining expensive catalysts, in situ purification, enhancing reaction rate, and reducing postprocessing of the reaction (by) products. In this article, two different ways were used to classify the various types of membrane reactors. One is based on whether the membrane is catalytic or noncatalytic, selective or nonselective, and whether or not a packed bed or a fluidized bed of catalysts is being used. The second classification is based on the membrane role: the extractor‐type, the distributor‐type, and the contactor‐type membrane reactors. This article presents the key features of these three types of reactors and the various classes of reactions these reactors have been applied, with emphasis on conventional (i.e., nonbiochemical) reaction systems.
