Integration of solar energy into absorption refrigerators and industrial processes
Chemical Engineering and Technology, 2010Co-Authors: Eman A. Tora, Mahmoud M. El-halwagiAbstract:Absorption Refrigeration is gaining increasing attention in industrial facilities to use process heat for partially or completely driving a cooling cycle. This paper introduces a systematic approach to the design of absorption Refrigeration systems for industrial processes. Three sources of energy are considered to drive absorption refrigerators: excess process heat, solar energy, and fossil fuels. To handle the dynamic nature of solar energy, hot water tanks are used for energy storage and dispatch. Thermal pinch analysis is performed to determine the amount of available excess heat and the required Refrigeration Duty. Next, a multiperiod optimization formulation is developed for the entire system. The procedure determines the optimal mix of energy forms (solar versus fossil) and the dynamic operation of the system. Three case studies are solved to demonstrate the effectiveness and applicability of the devised procedure.

introducing a hybrid multi generation fuel cell system hydrogen production and cryogenic co2 capturing process
Chemical Engineering and Processing, 2017Co-Authors: Mehdi Mehrpooya, Cyrus Rahbari, S Ali M MoosavianAbstract:Abstract A combined system containing molten carbonate fuel cell power plant, coal gasification, hydrogen production cryogenic CO 2 capture, Rankine steam cycle and ammonia-water absorption Refrigeration system is introduced and analyzed. In this process, power, heat and cooling are produced. An electrochemical model is developed to validate the experimental results of the fuel cell. In this system at first coal burn with oxygen and produce synthesis gas which is primary fuel for molten carbonate fuel cell and hydrogen production. Outlet gases which contain carbon dioxide are sent to the cryogenic CO 2 capture system and hydrogen is separated from CO 2 . Effect of key parameters on performance of the process is investigated. The power output from the system is 6.55 MW which 6 MW is gained from the fuel cell and 0.55 MW from the heat recovery and steam cycle. Also, this process produce 90 kmol/h hydrogen and 90% of the produced CO 2 is captured. Electrical efficiency of the hybrid system is 58% (LHV). Refrigeration Duty (−30 °C) and the recovered heat are 101.2 kW and 22.11 kW respectively.
