Themodynamics Limits and Energetic Analysis of Chemical Process Intensification
MetadataShow full item record
Many energy technologies are based on the chemical process such as conversion, separation and storage within a single flow-sheet. This chemical process can be intensified by combining several operation units in a single unit, which leads to a fundamentally cleaner, safer, more compact and more energy-efficient technology. However, for many chemical technologies, the theoretical limit of intensification is currently unknown. In this project, fundamental concepts of thermodynamics (e.g., 1st law, 2nd law, enthalpy and entropy calculation, Gibbs free energy minimization, mole balance and stoichiometric coefficient, heat, work, and exergy) are precisely applied, also improving the constraints of NLP formulation model. To this end, ultimate goal of this work is to achieve the maximum possible with accurately describing actual chemical phenomenon. This work can be also applied for many different chemical models such as fuel processing plants and energy sectors. First analysis is conducted on the methane reforming alternatives in syngas production model with small number of chemical species and reaction pathways, and next, the model is expanded to include various conversion routes of chemicals; methanol synthesis and ethane reforming are analyzed.
