RFID system plays a major role in asset tracking but its performance may get challenged when it has to work in extreme atmospheric conditions. RFID system can play an important role in military or defense purpose to track the land mines, military containers etc. Keeping these things in mind, this research work was carried out for the military areas which are situated in arid and semiarid regions. In this research work, experimental investigation, statistical analysis and optimization of the low frequency RFID system read range has been carried out with respect to four major input parameters i.e. varying sandy soil grain sizes (0.45 mm, 0.78 mm, 1.18 mm, 1.6 mm and 2 mm) which is present in between RFID reader and tag, temperature (15 °C to 50 °C), humidity (35 %RH to 70 %RH) and sandy soil layer thickness (0 mm to 90 mm). Here the optimization is being done by using response surface methodology (RSM). From the investigations and optimization it was found that maximum value of read range which the LF RFID system can attain is 118.14 mm for the optimum combination of input variables i.e. temperature, soil layer thickness, relative humidity and soil grain size were found to be 25.606 °C, 0 mm, 35 % and 2 mm respectively.

“…37 The BSFC is lower when the calorific value is greater because a decrease in the calorific value of fuel leads to an increase in the amount of fuel required to produce the same power output. 38 The comparison of the BSFC of test fuel with advanced IT, ORG, and retarded IT is shown in Figure 3(a) and (b). According to the data shown in Figure 3(a), the BSFC for diesel is 258.8 g/kW-h at 80% load; however, WPO10D90, WPO20D80, and WPO show increased BSFC than diesel were 9.4%, 11.3%, and 20.2%, respectively at ORG.…”

Fossil fuels are a major global concern due to escalating demand and current geo-politics. So demand has been arising for alternative fuel for I C engines. Alternatively, the generation of waste plastic is a severe environmental problem due to global disposal issues; however, it may be converted into alternative fossil fuel with minor amendments in fueling systems. So In this study, blends of waste plastic oil (WPO) have been investigated on CRDI diesel at variable injection timings (IT) (from 26°bTDC to 14°bTDC) to address above mentioned problems. The effect of different injection timings has been analyzed for WPO blends fuels, WPO10D90 (10% WPO+90% Diesel) and WPO20D80 (20% WPO+80% Diesel) and compared with baseline diesel fuel. In the experimental investigations, WPO20D80 achieved optimum results at IT of 17°bTDC; however, the original injection timings (ORG) was 23°bTDC. The optimal result has been provided as 6.7% greater BTE for WPO20D80 at 17°bTDC injection timing, and CO and NOx emissions have been reduced by 16% and 2.15%, respectively. So, suitable IT settings provided considerable improvement in performance and emissions for WPO blends with respect to baseline fuel and original injection timings. Furthermore, it can potentially be a long-term solution for the waste plastic disposal issue.

“…Biodiesel can be produced from the transesterification of vegetable oil or animal fat with alcohol. Biodiesel with a target of 20% blending is expected to increase from 19.8 to 31.1 billion liters in 2020 and 2030, respectively [1]. The rapidly increasing demand for biodiesel has led to a high amount of glycerol, a low-value byproduct.…”

Process and Energy Intensification of Glycerol Carbonate Production from Glycerol and Dimethyl Carbonate in the Presence of Eggshell-Derived CaO Heterogeneous Catalyst

et al. 2021

The process and energy intensifications for the synthesis of glycerol carbonate (GC) from glycerol and dimethyl carbonate (DMC) using an eggshell-derived CaO heterogeneous catalyst were investigated. The transesterification reaction between glycerol and DMC was typically limited by mass transfer because of the immiscible nature of the reactants. By varying the stirring speed, it was observed that the mass transfer limitation could be neglected at 800 rpm. The presence of the CaO solid catalyst made the mass transport-limited reaction process more prominent. Mass transfer intensification using a simple kitchen countertop blender as an alternative to overcome the external mass transfer limitation of a typical magnetic stirrer was demonstrated. A lower amount of the catalyst and a shorter reaction time were required to achieve 93% glycerol conversion or 91% GC yield, and the turnover frequency (TOF) increased almost 5 times from 1.5 to 7.2 min−1 when using a conventional magnetic stirrer and countertop blender, respectively. In addition, using a simple kitchen countertop blender with 7200 rpm, the reaction temperature of 60 °C could be reached within approximately 3 min without the need of a heating unit. This was the result of the self-frictional heat generated by the high-shear blender. This was considered to be heat transfer intensification, as heat was generated locally (in situ), offering a higher homogeneity distribution. Meanwhile, the trend toward energy intensification was promising as the yield efficiency increased from 0.064 to 2.391 g/kJ. A comparison among other process intensification techniques, e.g., microwave reactor, ultrasonic reactor, and reactive distillation was also rationalized.
