This paper presents a neural network based strategy for the modelling and optimisation of distillation columns incorporating the second law of thermodynamics. Real time optimisation of distillation columns based on mechanistic models is often infeasible due to the effort in model development and the large computation effort associated with mechanistic model computation. This issue can be addres...

Design and operation of chemical plants involves a combination of synthesis, analysis and evaluation of alternatives. Suchactivitieshave traditionallybeendrivenbyeconomic factorsfirst, followedbyengineering, safety and environmental considerations. Recently, chemical companies have embraced the concept of sustainable development, entailing renewable feedmaterials and energy, non-toxic and biode...

For the high utilization of abundant lignocellulose, which is difficult to directly convert into ethanol, an energy-efficient ethanol production process using acetic acid was examined, and its energy saving performance, economics, and thermodynamic efficiency were compared with the conventional process. The raw ethanol synthesized from acetic acid and hydrogen was fed to the proposed ethanol co...

Abstract This project attempts to evaluate the effect of nanofluids on thermal performance and economic parameters shell tube heat exchangers. First, two thermodynamic processes including combined power (CHP) system solar-driven organic Rankine cycle (ORC) are simulated using Aspen HYSYS. The CHP ORC systems can produce 25 MW 175.8 kW electrical power, respectively. Thereafter, use in exchanger...

Nowadays, clean and high-power generation is essential matters worldwide. To be improved optimized, power plants require accurate models that can introduced to process simulators. There various commercial software for industrial simulation which not accessible everyone. The open-source DWSIM simulator the first chemical engineering code offers many tools better study of plants. In this paper, w...
