“…Membrane technology may be a viable option for separating glycerol from biodiesel, but special efforts are necessary to prevent membrane fouling and clogging [34]. Other emerging technologies, such as high-voltage electrolysis, may be good candidates for separating glycerol from biodiesel [35]. Distillation has traditionally been used to separate and recover methanol [36].…”

Cottonseed oil (CSO) is well known as one of the commercial cooking oils. However, CSO still needs to compete with other edible oils available in the market due to its small production scale and high processing cost, which makes it a potential candidate as a feedstock for biodiesel production. To date, transesterification is the most widely applied technique in the conversion of vegetable oil to biodiesel, with glycerol produced as a by-product. Large-scale biodiesel production also implies that more glycerol will be produced, which can be further utilized to synthesize hydrogen via the steam reforming route. Therefore here, an integrated biodiesel and hydrogen production from CSO was simulated using Aspen Hysys v11. Simulation results showed that the produced biodiesel has good characteristics compared to standard biodiesel. An optimum steam-to-glycerol ratio for hydrogen production was found to be 4.5, with higher reaction temperatures up to 750 °C resulting in higher hydrogen yield and selectivity. In addition, a simple economic analysis of this study showed that the integrated process is economically viable.

“…En cambio, para un voltaje de 3000 V y una distancia entre electrodos de 6 cm se logró la misma separación en un tiempo de 45,3 segundos. En los últimos años han aparecido en la bibliografía muy pocos trabajos de varios autores que utilizan esta técnica para purificar biodiésel obtenido de fuentes diversas (Abbaszadeh et al, 2013, 2014; Barakat y Mayer-Laigle, 2017; Ratanabuntha et al, 2018;Susumu, 2018;Trisnaliani y Zikri, 2018;Utama Putra et al, 2018;Xie et al, 2011).

Con el propósito de aplicar una tecnología limpia y de bajo consumo energético en la separación de emulsiones, se construyó un separador electrostático de 1,0 dm 3. Se utilizaron electrodos de cobre rectangulares. Para los ensayos se prepararon emulsiones de glicerina (10% v/v) en biodiésel. Como agente emulsificante se utilizó licitina. Los voltajes empleados fueron 3000, 6000 y 9000 voltios; y las distancias entre electrodos fueron 2, 4 y 6 cm. Para cada ensayo se alcanzó la separación completa de la emulsión y se registraron los tiempos necesarios. Se determinó que existe un efecto tanto individual como combinado de los factores ensayados en la separación de la glicerina del biodiésel. La distancia entre electrodos fue la variable que mayor efecto produjo en la separación, seguidos del voltaje y la combinación de voltaje/distancia. Los tiempos de separación observados varían entre 8,3 y 45,3 segundos.

“…Glycerol may be separated from oil more quickly with a high-voltage device than by using the gravity approach. Because it can speed up the process of separating biodiesel from glycerol and other undesirable chemicals, the separation process, assisted by a voltage electric current, can yield positive results [43,44]. Figure 13 illustrates the impact of a high voltage on the duration of glycerol separation for pongamia and jatropha oils at a distance of 2.5 cm between electrodes.…”

The biodiesel industry is a promising field globally, and is expanding significantly and quickly. To create a biodiesel business that is both sustainable and commercially feasible, a number of studies have been conducted on the use of non-edible oils to produce biodiesel. Thus, this study highlights biodiesel synthesis from non-edible plant oils such as pongamia and jatropha using a glycerol separation technique with an AC high voltage method through the transesterification reaction. In this context, non-edible plant oil has emerged as an alternative with a high potential for making the biodiesel process sustainable. Moreover, the study introduces how the created biodiesel fuel behaves when burned in a diesel engine. The results showed that the optimum conditions for creating biodiesel were a temperature of 60 °C, a potassium hydroxide catalyst percentage by weight of oils of 1%, and a stirring time of 60 min at a 5:1 (v/v) ratio of methanol to oil. A high-voltage procedure was used to separate glycerol and biodiesel using two electrodes of copper with different distances between them and different high voltages. The results showed that, for a batch of 15 L, the minimum separating time was 10 min when the distance between the copper electrodes was 2.5 cm, and the high voltage was 15 kV. The density, kinematic viscosity, and flash point of jatropha oil were reduced from 0.920 to 0.881 g/cm3 at 15 °C, from 37.1 to 4.38 cSt at 40 °C, and from 211 to 162 °C, respectively, for the production of biodiesel. Additionally, the density, kinematic viscosity, and flash point of pongamia oil were reduced from 0.924 to 0.888 g/cm3 at 15 °C, from 27.8 to 5.23 cSt at 40 °C, and from 222 to 158 °C, respectively, for the production of biodiesel. The calorific value of jatropha oil was increased from 38.08 to 39.65 MJ/kg for the production of biodiesel, while that of pongamia oil was increased from 36.61 to 36.94 MJ/kg. The cetane number increased from 21 for oil to 50 for biodiesel and from 32 for oil to 52 for jatropha and pongamia biodiesel, respectively. In order to run an air-cooled, single-cylinder, four-stroke diesel engine at full load, the produced biodiesel fuel was blended with diesel fuel at different percentages—10, 20, and 30%—for jatropha and pongamia methyl esters. The produced engine power values were 3.91, 3.69, and 3.29 kW for B10, B20, and B30, respectively, compared with the engine power value of jatropha methyl ester, which was 4.12 kW for diesel fuel (B00); meanwhile, the values were 3.70, 3.36, and 3.07 kW for B10, B20 and B30, respectively, for pongamia methyl ester. The findings suggest that the biodiesel derived from non-edible oils, such as pongamia and jatropha, could be a good alternative to diesel fuel.
