“…Also, this analysis considers the evaluation of variables like accumulated cash flow (CCF), payback period (PBP), return of investment, and net present value. 37 It is worth pointing out that this methodology considered the evaluation of the discounted payback period (DPBP) as long as the traditional PBP does not takes into account the change in the value of money over plantlife. 38 NVOC is the normalized variable operating cost, C i v is the selling price of product i, m i is the mass flow of product i, PAT is the profit after taxes, int is the interest rate, AFC is the annualized fixed cost, FCH is the fixed costs, AOC is the annualized operational costs, TCI is the total capital investment, and FCI is the fixed capital investment.…”

New ways and technologies for synthesizing adsorbent materials have been emerging based on the green chemistry concept for the sustainable use of available resources. In this sense, the chitosan-based products arise as a promising technology alternative for application of several fields that include mitigation, prevention, and control of environmental issues. Nevertheless, there is a lack of information about the development and behavior of these topologies at the industrial scale. This study addressed the techno-economic and sensitivity analyses as decision-making tools to assess promising topologies for production of chitosan-based bio-adsorbents. From the data provided by process inventory, economic analysis of these routes was implemented. The evaluation allowed obtaining a start point market price for chitosan microbeads (64.40 $/t) and chitosan microbeads modified with TiO 2 nanoparticles (37 $/t). The economic analysis also showed that there is a vast potential to explore the chitosan market that enables generation of very profitable businesses from the implementation of those processes, considering the obtained economic performance indicators for both topologies. It is crucial to highlight that these indicators were slightly higher for chitosan microbead production. In addition, the sensitivity analysis indicated that the chitosan-TiO 2 process could resist higher fluctuations in the operating costs, which might indicate that this topology might be a reliable alternative between evaluated cases.

“…154 The sensitivity analysis on process economics allowed estimating those effects associated with changes in the operating cost, feedstock purchase cost, and product selling price. 155 In this sense, Perez et al 156 introduced the technoeconomic sensitivity analysis to evaluate biorefineries, applying a case study for palm-based topologies. The methodology included economic uncertainties of economic variables to anticipate possible variations in a chemical plant's economic behavior.…”

These days, developing sustainable chemical facilities to generate biofuels, energy, bioproducts, and value-added chemicals has attracted attention. The above involves changing the traditional conception of transformation processes into more sustainable production based on the green chemistry principles, renewable energies, and the triple dimensions of sustainable development. Consequently, the addition of sustainability issues in process synthesis, analysis, and optimization of bioprocesses has become increasingly noteworthy. This study reports a literature review concerning the sustainable chemical process design framework based on process synthesis, analysis, and optimization methodologies. Studies on biorefinery/process synthesis approaches are analyzed and compared, offering a detailed overview of selected literature. These included hierarchical, mathematical, and mixed approaches. This review also outlined indexes and indicators for measuring sustainability in process design considering exergetic/energetic, environmental, economic, and safety aspects. It is worth mentioning the role that exergetic metrics are expected to play in measuring global process sustainability. Finally, the current research gap of process integration is analyzed, considering pinch analysis techniques, simultaneous heat and mass integration, and hybrid intensification−integration approaches.

“…Since the thermo-economic analysis aims to investigate the energetic technical parameters and also the financial indices to estimate if any thermal plant would be feasibly or not [18], the needs to search for the ideal input configuration in terms of the energetic and economic domain have been mentioned in many studies on polygeneration systems, as it could be seen in [19,20]. In this context, using different technical methods to optimize the thermal systems have been applied to find the best configuration for energetic and economic efficiency using the Four E technique [21], artificial neural network [22], using the TRNSYS function the optimization of the economic index [23], MOPSO algorithm [24] or even combining different techniques of optimization such as pessimistic and optimistic criteria [25]. Previously, Panahizadeh et al [26] presented an analogous study using the exergetic parameters as the basis of the optimization method trying to minimize the exergy destruction by applying the particle swarm optimization (PSO) algorithm.…”

Absorption chillers are one of the most used equipment in industrial, commercial, and domestic applications. For the places where high cooling is required, they are utilized in a network to perform the cooling demand. The main objective of the current study was to find the optimum operating conditions of a network of steam absorption chillers according to energy and economic viewpoints. Firstly, energy and economic analysis and modeling of the absorption chiller network were carried out to have a deep understanding of the network and investigate the effects of operating conditions. Finally, the particle swarm optimization search algorithm was employed to find an optimum levelized total costs of the plant. The absorption chiller network plant of the Marun Petrochemical Complex in Iran was selected as a case study. To verify the simulation results, the outputs of energy modeling were compared with the measured values. The comparison with experimental results indicated that the developed model could predict the working condition of the absorption chiller network with high accuracy. The economic analysis results revealed that the levelized total costs of the plant is 1730 $/kW and the payback period is three years. The optimization findings indicated that working at optimal conditions reduces the levelized total costs of the plant by 8.5%, compared to the design condition.
