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.

“…The alternatives are represented (step 2) in three different levels of aggregation presented in the next sections. The third and fourth steps are merged in the application of the thermodynamic insights theory developed by Jaksland et al (1995). The thermodynamic insights theory employs physicochemical properties and their relationships to separation techniques for design and synthesis of separation processes.…”

-Based on reliable property values, a framework for biodiesel process synthesis, design and simulation was created. To assess the capabilities of this framework, the biodiesel production from degummed oil and ethanol was taken as a process design case study. The process is synthesized based on a systematic methodology that uses knowledge and the thermodynamics insight theory to generate and evaluate process alternatives. A preliminary process design is proposed and simulated on COCO (CAPE-OPEN-to-CAPE-OPEN) process simulator confirming the contribution of this work as a tool for the application of process and product design techniques.

“…In reality, several properties of the molecules or materials being designed play a role in determining the performance of the process and they do so in a nonlinear way, with unknown or indeed variable relative importance. 25,35 Furthermore, many of the molecular/mixture properties vary with operating conditions, that is, they are secondary properties in the sense discussed by Jaksland et al 38 The optimal operating conditions of the process, in turn, depend on the material that is chosen, as well as the process constraints and specifications. Even the feasible operating region depends on the material chosen: the range of temperatures and pressures at which a solvent is in the liquid state depends on its molecular structure; some choices of molecular structure may lead to the appearance of new phases, perhaps due to immiscibility or partial miscibility between the various components in the process.…”

Outer approximation algorithm with physical domain reduction for computer‐aided molecular and separation process design

Integrated approaches to the design of separation systems based on computer-aided molecular and process design (CAMPD) can yield an optimal solvent structure and process conditions. The underlying design problem, however, is a challenging mixed integer nonlinear problem, prone to convergence failure as a result of the strong and nonlinear interactions between solvent and process. To facilitate the solution of this problem, a modified outer-approximation (OA) algorithm is proposed. Tests that remove infeasible regions from both the process and molecular domains are embedded within the OA framework. Four tests are developed to remove subdomains where constraints on phase behavior that are implicit in process models or explicit process (design) constraints are violated. The algorithm is applied to three case studies relating to the separation of methane and carbon dioxide at high pressure. The process model is highly nonlinear, and includes mass and energy balances as well as phase equilibrium relations and physical property models based on a group-contribution version of the statistical associating fluid theory (SAFT-c Mie) and on the GC 1 group contribution method for some pure component properties. A fully automated implementation of the proposed approach is found to converge successfully to a local solution in 30 problem instances. The results highlight the extent to which optimal solvent and process conditions are interrelated and dependent on process specifications and constraints. The robustness of the CAMPD algorithm makes it possible to adopt higher-fidelity nonlinear models in molecular and process design.
