The research carries out the regression of thermodynamic and kinetic parameters, rigorous design of four process configurations, optimization, carbon emission analysis, and control. The results from steady-state analysis reveal that the solvent-free coupled reaction/distillation (SFCRD) process is the most promising. It reduces 40.09% of total annual cost and 45.09% of CO2 emission from the base case, the separated reactor-distillation process. Besides, the CO2 emission rate of the SFCRD process is found 35.29% and 65.91% less than the recently reported upper and the middle partition reactive dividing-wall column process, respectively, indicating the unfavorability of intensifying this reacting system through reactive distillation. Finally, a control structure for the SFCRD process is established for effectively handling the disturbances from the flowrate, composition and catalyst deactivation. Through the dynamic simulation, the closed-loop control results were revealed satisfactory.glycerol; solketal; process design; simulated annealing; coupled reaction; distillation; carbon emission; GLYCEROL KETALIZATION; CATALYTIC CONVERSION; REACTOR; ACETONE; CO2journal article10.1016/j.psep.2021.11.0112-s2.0-85119202751WOS:000721498200005http://www.scopus.com/inward/record.url?eid=2-s2.0-85119202751&partnerID=MN8TOARS108279306
