		+	== Effect of pressure on heat duties in pressure swing distillation: A simulation study ==
		+
		+	'''Authors:''' D. S. V. J. P. Koteswari M.; Vivek Kumar
		+
		+	'''Abstract:''' Acetone-methanol mixture is a typical minimum-boiling azeotropic system which cannot be separated in its constituent liquids using conventional techniques. At the same time, pressure swing distillation (PSD) is a separation technique which does not put the requirement of an additional third component to drive the separation process. The current work is based on the application of PSD for the minimum boiling azeotropes. The current study presents a theoretical investigation done over pressure sensitivity for the PSD of acetone-methanol mixture. Various thermodynamic models have been used. The azeotrope composition shift showed a direct effect on reboiler duty. This study also presented the optimum best operating pressure which targeted total energy consumption. DWSIM, the open source simulation software, has been used for all the simulations and it matched well with the results obtained using commercial software PRO II. The study presents the relation between high pressure column pressure and heat duty. It also discusses the possibility of heat integration and capital cost to decide the range of operating pressure.

		+	== Transfer learning for process design with reinforcement learning ==
		+
		+	'''Authors:''' Qinghe Gao, Haoyu Yang, Shachi M. Shanbhag, Artur M. Schweidtmann
		+
		+	'''Abstract:''' Process design is a creative task that is currently performed manually by engineers. Artificial intelligence provides new potential to facilitate process design. Specifically, reinforcement learning (RL) has shown some success in automating process design by integrating data-driven models that learn to build process flowsheets with process simulation in an iterative design process. However, one major challenge in the learning process is that the RL agent demands numerous process simulations in rigorous process simulators, thereby requiring long simulation times and expensive computational power. Therefore, typically short-cut simulation methods are employed to accelerate the learning process. Short-cut methods can, however, lead to inaccurate results. We thus propose to utilize transfer learning for process design with RL in combination with rigorous simulation methods. Transfer learning is an established approach from machine learning that stores knowledge gained while solving one problem and reuses this information on a different target domain. We integrate transfer learning in our RL framework for process design and apply it to an illustrative case study comprising equilibrium reactions, azeotropic separation, and recycles, our method can design economically feasible flowsheets with stable interaction with DWSIM. Our results show that transfer learning enables RL to economically design feasible flowsheets with DWSIM, resulting in a flowsheet with an 8% higher revenue. And the learning time can be reduced by a factor of 2.

		+	== Process Simulation for Low Emission Hydrogen Production Using DWSIM ==
		+
		+	'''Authors:''' Ganesan Subramanian & Neale R. Neelameggham
		+
		+	'''Abstract:''' Low emission hydrogen and blended natural gas production technologies are at the forefront of meeting NETZERO50 objectives to mitigate climate change. This paper demonstrates how a chemical flowsheet simulator DWSIM (DWSIM – The Open Source Chemical Process Simulator “Chemical Process Simulation for Everyone: DWSIM for Desktop is free and open-source”, [online] Available at: https://dwsim.org [accessed August 18,1922]) is used in evaluating the effectiveness of material conversion and optimal energy requirements for thermochemical processes involving light elements C and H which are at the heart of zero or low emission fuel generation from hydrocarbons. DWSIM simulator is very flexible in that the focus can be on a single piece of equipment like a reactor where one can rigorously assess equilibrium or kinetic conversions or a complex network of an entire manufacturing facility with multiple comparison scenarios to evaluate economics.

		+	== Green ammonia production via the integration of a solid oxide electrolyser and a Haber-Bosch loop with a series of solid electrolyte oxygen pumps ==
		+
		+	'''Authors:''' Duncan A. Nowicki, Gerry D. Agnew, John T.S. Irvine
		+
		+	'''Abstract:''' A conceptual design for a small-scale green ammonia plant is presented in which ammonia synthesis was realised via a Haber-Bosch loop using hydrogen produced by a solid oxide electrolyser and nitrogen purified from air with a series of solid electrolyte oxygen pumps. The system operated with an energetic efficiency of 52.12%, very close to a cryogenic ASU reference system where an efficiency of 52.89% was achieved. The specific energy consumption was 9.94 kWh/kgNH3. Whilst these were encouraging results, opportunities exist to improve system design further. For example, greater heat integration could allow for steam required by the electrolyser to be raised using waste heat from the series of oxygen pumps.

		+	== Designing interactive augmented reality application for student's directed learning of continuous distillation process ==
		+
		+	'''Authors:''' Sitian Gao, Yunpeng Lu, Ching Hui Ooi, Yiyu Cai, Poernomo Gunawan
		+
		+	'''Abstract:''' Continuous distillation is an important separation process in chemical engineering curriculum. Conventionally, it is often taught as black box diagrams that lack user visibility, thus preventing students from developing a deeper understanding and comprehension. This paper presents the technical development of the mobile AR application and its implementation in the curriculum of Chemical Engineering Unit Operations at Nanyang Technological University Singapore. The mobile AR application is to provide interactive visualization and real-time numerical simulation to promote students’ active learning in the classroom. The results of the pre-test and post-test indicated that the AR application helped students gain a better understanding of the principle and fundamental concepts of the distillation process. The evaluation survey with 6-point likert scale questions shows that students had a positive experience using the mobile AR application and it has enhanced their learning experience, as suggested by a mean evaluation score of 5.18 out of 6.0.

		+	== In a biogas power plant from waste heat power generation system using Organic Rankine Cycle and multi-criteria optimization ==
		+
		+	'''Authors:''' Cagatay Varis, Selin Ozcira Ozkilic
		+
		+	'''Abstract:''' Increasing energy consumption, rapid population growth, and technological developments have increased the need for energy demand day by day. At the point of meeting this need, renewable energy is an important alternative resource that can replace rapidly exhaustible fossil fuels. There are many renewable energy sources such as sun, wind, hydrogen, geothermal, and biogas. Biogas, one of the most important renewable energy sources, is mainly used as fuel in combined heat-power (CHP) engines/gas engines and transformed into electrical energy. However, the efficiency of these engines is low owing to the fact that a considerable amount of the energy that enters with the combustion of biogas is thrown into the atmosphere as exhaust gas. In this context, the recovery of the waste heat of 26 gas engines with a temperature of 475–500 °C in the Silivri region of Istanbul and producing biogas from household wastes was studied. Calculate the waste heat values according to the exhaust gas flow, temperature, and pressure values to be taken from the chimney outlet of the gas engines in the facility. Subsequently, the determination of the parameters of the ORC (Organic Rankine Cycle) and the optimum consumption values of the equipment in the whole system in the loop as well as the optimum ORC mechanical power will help manage and optimize the electricity production.

-'''Abstract:''' The study of the viability of hydrogen production as a sustainable energy source is a current challenge, to satisfy the great world energy demand. There are several techniques to produce hydrogen, either mature or under development. The election of the hydrogen production method will have a high impact on practical sustainability of the hydrogen economy. An important profile for the viability of a process is the calculation of energy and exergy efficiencies, as well as their overall integration into the circular economy. To carry out theoretical energy and exergy analyses we have estimated proposed hydrogen production using different software (DWSIM and MATLAB) and reference conditions. The analysis consolidates methane reforming or auto-thermal reforming as the viable technologies at the present state of the art, with reasonable energy and exergy efficiencies, but pending on the impact of environmental constraints as CO2 emission countermeasures. However, natural gas or electrolysis show very promising results, and should be advanced in their technological and maturity scaling. Electrolysis shows a very good exergy efficiency due to the fact that electricity itself is a high exergy source. Pyrolysis exergy loses are mostly in the form of solid carbon material, which has a very high integration potential into the hydrogen economy.

 '''Abstract:''' Actualmente la simulación de procesos por ordenador en la ingeniería química es una etapa fundamental en la puesta en marcha y control de cualquier proceso en el campo de la petroquímica, donde permiten predecir los resultados de cualquier etapa del proceso productivo. La comparativa entre el comportamiento de dos simuladores populares, el UNISIM, disponible bajo licencia y el DWSIM, de código abierto, tiene una importancia económica significativa, ya que permite obtener resultados de un programa de aplicación industrial utilizando uno de uso académico. Delimitando el estudio para los hidrocarburos aromáticos Tolueno y Benceno, principales componentes de una mezcla BTX. Mediante la revisión de la bibliografía pertinente se estable una base teórica firme, para a continuación, proceder a modelar el comportamiento de estos componentes y una mezcla equimolar de los mismos, a través de los simuladores se obtienen las principles propiedades físico-químicas de fase y propiedades termodinámicas, luego, de aquellas propiedades que presentan mayores diferencias entre simuladores se proponen medios para corregirlas, buscando así obtener resultados con DWSIM lo más semejantes posibles a los arrojados por UNISIM, para finalizar se proponen recomendaciones para completar el estudio y poder emular el modelado de una columna de platos de simulador bajo licencia en el programa de código abierto.
