Simultaneous Design and Controllability Optimization for the Reaction Zone for Furfural Bioproduction

Abstract

For sustainable production and consumption, emerging green technologies must be optimized in order to achieve a minimal environmental impact, a maximal economic impact, and dynamic behavior. The need for environmentally sustainable production and consumption is now one of the main developmental goals. To enable a more sustainable production in the chemical sector, new green chemical technologies from renewable feedstock such as furfural (a chemical compound produced from biomass used as a building block in the production of biofuels) are currently being developed. Furfural, a versatile chemical, is also employed as a solvent, an extractant base for fungicides, and a platform for other compounds. In this work, the simultaneous optimization of design parameters and control properties, which are highly relevant targets according to the principles of green chemistry, is performed within the reaction zone in the production process of furfural from biomass. The Differential Evolution with Taboo List algorithm (DETL) is used to carry out the multiobjective optimization. The total annual cost (TAC), eco-indicator 99 (EI99), and condition number, which represent the objective functions for a sustainable process, are combined as economic, environmental, and controllability criteria, respectively. Based on the results, the operating conditions found allow for an acceptable furfural production of 2014.4 kg/h, which reduce costs by 39% and its environmental impact by 42% in a system with satisfactory control properties compared to a case base.

Advancements in Optimization and Control Techniques for Intensifying Processes

“…The HWA method assumes that the process flow sheet and control structure have been defined a priori, and it rapidly estimates the worst-case disturbance by using singular value calculations [115]. Segovia-Hernández and coworkers have proposed multi-objective optimization frameworks to assess economic and controllability features of intensified processes using the condition number as a controllability criterion [116][117][118]. Cabrera-Ruiz and coworkers proposed an open-loop operability criterion based on integrating the condition number in a multi-objective optimization framework to consider the simultaneous design and controllability of intensified distillation processes.…”

A Study on Green Consumption Behavior of Young People Empowered by Digital Economy Based on Double Goal Constraints

“…Lifestyle greening is measured to a large extent by the green consumption behavior of the residents. Green consumption behavior has become an important way for residents to participate in environmental co-governance in their daily lives [16][17][18][19][20]. In the context of building a beautiful China and led by the theory that green water and green mountains are golden mountains, how to stimulate residents' green consumption behavior has logically become a hot issue for theoretical research [21][22][23][24].…”
