In this study, the optimal design and operation of an Organic Rankine Cycle (ORC) system driven by solar energy is investigated. A two-tank sensible thermal storage configured to overcome intermittency energy. circulating fluid, also termed as heat transfer fluid (HTF) that connects collector ORC plays a critical role in system. The mass flowrate HTF determines both temperature amount absorbed from collector. simulation-based optimization model developed work. Process simulation performed...
Abstract The uncertainty and sensitivity analysis are evaluated for their usefulness as part of the model‐building within Process Analytical Technology applications. A mechanistic model describing a batch cultivation Streptomyces coelicolor antibiotic production was used case study. input resulting from assumptions propagated using Monte Carlo procedure to estimate output uncertainty. results showed that significant exists in outputs. Moreover biomass, glucose, ammonium base‐consumption were...
Biocatalysis has been attracting increasing interest in recent years. Nevertheless, most studies concerning biocatalysis have carried out using single enzymes (soluble or immobilized). Currently, multiple enzyme mixtures are attractive for the production of many compounds at an industrial level. In this review, a classification multienzyme-catalyzed processes is proposed. Special emphasis placed on description multienzyme ex-vivo systems where several reactions by combination acting outside...
Abstract Significant progress in the area of simultaneous design and control for chemical processes has been achieved various methodologies have put forward to address this issue over last several decades. These methods can be classified two categories (1) controllability indicator‐based frameworks that are capable screening alternative designs, (2) optimization‐based integrate process system design. The major objective is give an up‐to‐date review state‐of‐the‐art challenging control....
The aim of this work is to develop group-contribution(+) (GC(+)) method (combined group-contribution (GC) and atom connectivity index (CI) method) based property models provide reliable estimations environment-related properties organic chemicals together with uncertainties estimated values. For purpose, a systematic methodology for modeling uncertainty analysis used. includes parameter estimation step determine parameters an establish statistical information about the quality estimation,...
This study aims to demonstrate the application of deep learning quantitatively describe long-term full-scale data observed from wastewater treatment plants (WWTPs) perspectives process modeling, analysis, and forecasting modeling. Approximately, 750,000 measurements including influent flow rate, air temperature, ammonium, nitrate, dissolved oxygen, nitrous oxide (N2O) collected for more than a year Avedøre WWTP located in Denmark are utilized develop neural network (DNN) through supervised...
The use of fluctuating renewable energy over a certain threshold may lead to an unmanageable mismatch between the electricity generation and demand profiles threatening grid's stability. In this study, innovative complex storage/conversion system is proposed for cogeneration electricity, cooling, water by integrating liquefied natural gas (LNG) regasification process, organic Rankine cycle, compressed air storage (CAES) system, multi-effect distillation unit. study attempts minimize CO2...
Quantitative structure-property relationships (QSPRs) are important tools to facilitate and accelerate the discovery of compounds with desired properties. While many QSPRs have been developed, they associated various shortcomings such as a lack generalizability modest accuracy. Albeit machine-learning deep-learning techniques integrated into models, another shortcoming has emerged in form transparency interpretability models. In this work, two interpretable graph neural network (GNN) models...
