Recently, the disposal of waste oil-in-water cutting emulsion has become an urgent issue because of its extremely high chemical oxygen demand (COD). The present work focuses on treating the waste cutting emulsion generated from the Samsung Thai-Nguyen factory in Vietnam. This work used multistage methods to treat the waste cutting emulsion to meet the wastewater disposal requirement and characterize the oil recovered. The multistage methods consist of the flocculation method (stage 1) and Fenton oxidation (stage 2). The wastewater after stage 1 treatment has a COD reduction efficiency of 98.24% at the condition of pH 5, Al2(SO4)3 2 g/L, C-PAM 12 mg/L, stirring speed 50 rpm, and stirring time 15 minutes. At that condition, the COD value decreased from 147200 mg/L to 2484 mg/L. After stage 2, the COD value further decreased from 2484 mg/L to 85.4 mg/L with total COD removal efficiency increasing to 99.9% at the optimum conditions of pH 3, H2O2 : FeSO4 concentration ratio of 10 : 1, and FeSO4 concentration of 14.04 g/L. After the stage 2 treatment, the wastewater with the COD value of 85.4 mg/L and BOD5 value of 30 mg/L satisfied the Vietnam standard grade B and grade A, respectively, for industrial wastewater. The oil recovered from the treatment has a heating value of 38095 ± 8 kJ/kg, and thus, it could be reusable as fuel gas.

“…This means that the rate of fuel consumption is increased for the fuel blend with maximum density, viscosity, and minimum calorific value. 30 The fuel mass flow rate and specific fuel consumption is given in Figure 4. The mass flow rate of diesel is quite larger than the biodiesel and it is increased when increasing the engine load conditions.…”

In conventional diesel engines, the reactivity controlled combustion ignition (RCCI) systems find to be offer better emission and engine performances. The main aim of this work is to study and enhance the emission, combustion, and performance characteristics of the RCCI based diesel engine. In the present work, we compare and optimize the characteristics of the diesel engines when using methane added hydrogen and methanol fuels as low reactive fuels (LRF). The diesel and dimethyl ether added biodiesel (spirulina microalgae) are used as high reactivity fuels (HRF) with six different proportion rates. In this, initially, the experimental results are investigated by using methanol as LRF with HRF fuel, and better blend proportion is optimized by using bald eagle search optimization (BESO) performed in the Matlab platform. Then, the methane content added hydrogen is used as LRF with the optimized HRF fuel combinations. Finally, from both cases, the optimized experimental characteristics are predicted with the help of the Elman recurrent neural network based BESO. In which, the hydrogen gas contributed RCCI engine provide supreme engine characteristics such as 217.6 g/kWh of specific fuel consumption, 38.7% of brake thermal efficiency, 84.45 bar of cylinder pressure, and the CO 2 and NOx emissions are 539.2 g/kWh, and 1020 ppm. The result reveals that the proposed predicted results are superiorly validated the experimental outcomes with minimal errors.

“…Over sixty researchers some of whom include [17, 19, 23, 32, 36, 47-57, 61, 62, 64-70] studied alkali catalyst transesterification of different plant oil concerning their fuel properties such as density, viscosity, cetane number, cold flow properties, flash point, and calorific value. Their studies show the best quality alkyl ester under different transesterification circumstances [1,14,17,19,24,35,36,[47][48][49][50][51][52][53][54][55][56][57][71][72][73]. A review on biodiesel fuel specifications by [61] found that over 80% of scientists and researchers failed to extensively report on the fuel properties of biodiesel and their influence on performance in compression ignition engines.…”

“…Among the plant oil biodiesel studied, Jatropha curcas biodiesel and algae biodiesel stands out in terms of quality and good fuel properties for use in compression ignition engines [36,47,48,56,71,74,75]. Some studies [5,25,56,[76][77][78] even report that Jatropha seed oil or its blend with conventional diesel fuel can be used as diesel in compression ignition engines without engine modification.…”

“…Moreover, J. curcas has a yield per hectare of more than four times that of soybean and ten times that of corn [79]. Recent studies on the evaluation of 75 nonedible oils as biodiesel feedstocks, identified J. curcas as one of the most promising plants apart from algae [71,79,80]. J. curcas plant is very prolific, it grows on any type of soil, gets matured within a very short period, and produces large quantities of seed almost throughout the year.…”

Due to population explosion, and increased industrialization with urban and rural development, the need for increased energy utilization has become more intense. Petrodiesel that has been the main energy source for heavy-duty automobiles or machines has contributed immensely to environmental pollution leading to climate change, an increase in illnesses, and reduced lifespan. To combat this ugly situation arising from the utilization of Petrodiesel, biodiesel is produced from plant oil or animal fats to substitute for Petrodiesel in internal combustion engines, either as neat biodiesel or as a blend with Petrodiesel. Different scientists and researchers have produced biodiesel from edible and non-edible plant oils. Their reports show that biodiesel properties depend on the nature of the parent plant oil and the production procedures taken. These properties that are due mainly to its production procedures determining their performance in internal combustion engines. In this chapter, recent findings on biodiesel properties with their effects on performance in internal combustion engines are reviewed. Researchers’ reports show that the most suitable blend of biodiesel with Petrodiesel is B20. This blend consisting of 20% biodiesel with 80% Petrodiesel has equivalent performance as Petrodiesel with fewer pollutants and only 1–7% nitrogen oxide emission.
