Special Issue Information

Dear Colleagues,

With the onset of the Corona pandemic, the entire world economy, with very few exceptions, is on its knees. The oil industry in particular has been strongly affected, as evidenced by the unprecedented negative oil prices we have witnessed in the last few months.

Thus, within the framework of this meeting, we are interested in the subject of the rationalization of energy consumption through the optimization, audit, and control of processes. Mainly, our focus is on the different processes, electrification, heating and air conditioning, refining, petrochemicals, gas treatment, pharmaceuticals, food processing, etc., without of course forgetting conventional and new hybrid energy systems in addition to economic models combining fossil and renewable energies.

Based on these ideas, we are inviting authors to submit original research and review papers on a broad range of topics to this Special Issue on “Rationalization of Energy Consumption through the Optimization, Audit, and Control of Processes”. Experimental and modeling works focused on process optimization and energy metering in a wide variety of application fields as well as reviews or technical notes in terms of the synergy between conventional and renewable energy are highly welcome.

Kiln is a prime need in the ceramics industry, where energy loss is a major part which consumes about 60% production cost through thermal energy for different applications. Higher density of fired and tunnel kiln refractory material lowers the thermal diffusivity and the proper selection of fired material minimizes the energy loss along the kiln. In particular, this research analysed the results of a heat recovery system comprised of a metallic recuperator which gives around 8% energy savings in natural gas consumption. In this work, detailed power quality analysis of low-power factor motors of a tunnel kiln was carried out and a power factor improvement solution was suggested to save electrical energy with payback period of 0.8 y. The motor operating at a low-power factor consumes more reactive power which does not produce beneficial work. A low-power factor around 0.4 causes network power loss, increases in transformer loss and voltage drops. The solution with accumulative capacitance power of 148.05 uF was installed to achieve the power factor to 0.9. Flu gas analyzer was installed to monitor the range of O2 in pre-heating, oxidation, and firing zones of the kiln which should be ≥8% and 3%, respectively. Regression analysis for thermal energy consumption of a tunnel kiln is done to find the forecast thermal energy consumption. This analysis can be used to find operational efficiency, supporting decisions regarding dependent variable of thermal energy consumption and independent variable of production. This research is very helpful for the ceramics industry to mitigate the energy loss at SMEs as well as in mass production level. Full article
