Half-Day Talk on “Hybrid Liquid Desiccant System and Chimney Micro-Plant for Simultaneous Production of Fresh Water and Electricity”


Date: Saturday, 16th November 2019
Venue: IEM (Southern Branch) Training Centre, 24-B Jalan Abiad, Taman Tebrau Jaya, Johor Bahru
Speaker: Assoc. Prof. Dr. Ahmad Jais Alimin, Faculty of Mechanical and Manufacturing, UTHM


Rapid growth of global population, especially in poor developing regions without sustainable petroleum resource, have inevitably increase their concern on issues such as alternative energy resources and water security. Recently, a hybrid plant concept that uses liquid desiccant system for harvesting freshwater from the atmospheric and solar chimney for energy supply has been constructed and tested for simultaneous production of freshwater and electricity. Experimental and simulation works showed that the hybrid system is greatly influenced by the liquid desiccant’s properties (quality and concentration) and ratio of desiccant’s mass flow rate to mass flow rate of the processed humid air. By understanding the overall hybrid integration and operation efficiencies, future development towards upscaling the integrated solution, specific for those living in the humid and sunny regions, can be worked out systematically. The presentation on this topic is separated into a few sections beginning with the description about the solar chimney technology, followed by the concept of extracting water from the atmospheric, the methodology of combining both technologies, the construction and testing of the hybrid plant and lastly the summary on the findings and outcome from this research project. The main objective of this technical talk course is to give a better understanding for our young engineers and practicing engineers to get some insight on the above topic.
