A dividing‐wall column (DWC) was used for pretreating industrial multi‐component reformed gasoline (IMCRG). IMCRG consists of 16 components, which are non‐aromatics, benzene, toluene, xylenes & ethylbenzene, and heavy aromatics. Rigorous steady‐state simulations were conducted using Aspen Plus. Compared with a conventional direct and indirect two‐column sequence separation, the reduction in the total annualized cost (TAC) by a DWC can be up to 13.06 % (direct sequence) and 24.79 % (indirect sequence). To treat the noncondensable gas in the feed, a DWC flowsheet with a partial condenser was considered. Two control structures with a S/L ratio control strategy were proposed to control the DWC. Controllability analyses with respect to feed flow rate and feed composition disturbance were conducted to evaluate the control effect of the two structures by using Aspen Plus Dynamics. Finally, a feasible DWC control structure to pretreat IMCRG was obtained.

“…Likewise, dynamic high‐fidelity models of the process are represented using approximation and model reduction techniques for simultaneous design and control . Some practitioners considered several subproblems and solved the hierarchy of analyses in a decomposition‐based solution approach . Recently, Pistikopoulos et al decomposed the original system to explore the interaction between design and control using a multiparametric programming approach.…”

A trust‐region approach is presented to address the simultaneous design and control of large‐scale systems under uncertainty. The key idea is to represent the system using power series expansions (PSEs) as piecewise models in an iterative manner while the validity of those expansions is certified in a trusted region. The mean of squared errors is used as a metric to quantify the accuracy of the PSE approximations. Identified search regions specify the boundaries of the decision variables for the PSE‐based optimization problems. The proposed algorithm shows a significant accomplishment in locating dynamically feasible and near‐optimal design and operating conditions. The proposed approach was tested in a wastewater treatment plant and the Tennessee Eastman process. The results indicate that the proposed methodology leads to more economically attractive and reliable designs while maintaining the dynamic operability of the system in the presence of disturbances and uncertainty.

“…A disadvantage is that intensified processes possess specific and/or unique properties that may result in a more difficult or complex operation in the presence of disturbances. This is mainly due to the loss in degrees of freedom because of integration of unit operations, functions or phenomena [88][89][90][91].…”

Abstract:Recovering valuable compounds from waste streams of bio-based production processes is in line with the circular economy paradigm, and is achievable by implementing "simple-to-use" and well-established process separation technologies. Such solutions are acceptable from industrial, economic and environmental points of view, implying relatively easy future implementation on pilot-and full-scale levels in the bio-based industry. Reviewing such technologies is therefore the focus here. Considerations about technology readiness level (TRL) and Net Present Value (NPV) are included in the review, since TRL and NPV contribute significantly to the techno-economic evaluation of future and promising process solutions. Based on the present review, a qualitative guideline for resource recovery from bio-based production processes is proposed. Finally, future approaches and perspectives toward identification and implementation of suitable resource recovery units for bio-based production processes are discussed.
