“…This way, the possibility of designing biorefineries based on these raw materials is feasible, at least concerning biodiesel production. 18,22 However, the oxidative stability of the samples was below the lower limit established by the EN 14214 standard (8 hours), ranging from around 5 hours for rapeseed biodiesel and 2.5 hours for seed and frying biodiesel. Consequently, the use of antioxidants to comply with the standard is necessary.…”

“…1 Moreover, the use of heterogeneous catalysts could also be a good alternative to traditional ones, especially making the catalyst removal from the final product easier. 17 This way, if the production of biolubricants is based on transesterification, the raw material could play an important role in the development of a biorefinery, as many other similar sources have been considered in the literature [18][19][20][21][22] (see Figure 1). However, not many studies have pointed out the feasibility of the design of a biorefinery based on vegetable oils through transesterification, although some parts of the process (for instance fatty acid methyl esters [FAMEs] production) have been widely studied.…”

“…However, not many studies have pointed out the feasibility of the design of a biorefinery based on vegetable oils through transesterification, although some parts of the process (for instance fatty acid methyl esters [FAMEs] production) have been widely studied. 22 Also, this study presents three different biolubricants from vegetable oils (including wastes such as frying oil and rapeseed oil, which can be a suitable crop in climatically difficult regions), supplementing the range of biolubricants obtained from many different sources and chemical routes. 1 For instance, by using rapeseed (which is an interesting plant for rotation crop as it has a long tap root, showing good yields and resistance) as the basis of a biorefinery (as seen in the literature 18,20 ), in this case three main products are found: oil, biodiesel (FAMEs) and biolubricant (fatty acid complex esters).…”

A study about the production and characterization of biodiesel and, especially, biolubricants from different raw materials (ie, rapeseed, a mixture of corn and sunflower, and frying oils) is here performed. Optimal chemical conditions were used to carry out the transesterification of biodiesel and biolubricants, hence obtaining high yields in all investigated cases. The physical properties, such as fatty acid methyl ester profile, viscosity, viscosity index and oxidative stability, among others, are analyzed. The biodiesel products comply with the standards, according to the characteristics covered in this research. Regarding the biolubricants, the viscosity values are analogous to those found in the literature but showing longer induction points. These properties appear to be highly influenced by the fatty acid profile of the raw material, which is an important factor for both biodiesel and biolubricant performance. Therefore, the initial characterization of vegetable oils is an important stage for the optimal design of biorefineries. Finally, the use of transesterification for biodiesel and biolubricant production is also justified, as many valuable products (eg, glycerol, fatty acid methyl esters, and fatty acid complex esters) are obtained and some by-products (eg, methanol) can be reused.

“…The novel integrative approaches overcome the equilibrium limitation and reduce the production cost with an additional energy‐saving potential of 45 to 85% . The economic assessment of biodiesel plant design with an integrated approach revealed an 18% decrease in an overall cost . There is a great scope of equipment and energy integration for biodiesel production making the process economically attractive and practically feasible.…”

Biodiesel is a promising alternative to conventional fuels. Research on biodiesel has vast experimental findings, but the outcomes are not always unidirectional.The sequence of unit operation for various transesterification processes is studied. The review work emphasizes on the separation and purification of Jatropha-derived biodiesel. The study on the downstream processes of alcohol recovery, glycerol-rich and biodiesel-rich phase separation, and biodiesel purification techniques is the main part of this paper. The biodiesel purification includes wet and dry washing and membrane techniques. The purpose of the review is to find separation techniques that are less energy-intensive and environmentally friendly purification processes for biodiesel production from Jatropha. The strategies to reduce the cost of biodiesel production from Jatropha are discussed. The Jatropha biodiesel possesses huge potential as one of the alternative energy sources for commercial exploitation in India.

“…The first approach involves the simple selection of the most abundant FA present in the mixture [3] and the second approach involves the initial determination of the average properties of the FA mixture based on the contribution of the component FAs in the mixture. The model FA is then subsequently selected after a comparative assessment of the properties of possible model FAs and estimated average properties of the FA mixture [21,22]. The present study considers the second approach more comprehensively in determining the model FA best suited to model the DFA mixture, since in my view, the first approach is too simplistic to provide a sufficiently accurate basis for accurate simulations.…”

For the first time, a steady state computational simulation for the production of biodiesel from meat processing dissolved air flotation sludge via an integrated process of in-situ hydrolysis and esterification technologies has been investigated. Important thermophysical properties of the intrinsic lipids of dissolved air flotation sludge were estimated using chemical constituent fragment methods. The environmental performance and the economic performance of the biodiesel production process were assessed via the estimation of the net energy ratio (NER) and the unit production cost, respectively. Since electrical energy requirements may be satisfied via either non-renewable (case A) or renewable sources (case B), the NER was determined for both scenarios. To enhance the robustness of the study results, uncertainties in the NER and the unit cost of the biodiesel production process due to the variability of the underlying study assumptions were also assessed. Uncertainty analysis indicated that the likely range of the NER for the biodiesel production process for cases A and B are 1.76 to 3.32 and 1.82 to 3.36, respectively, at 95% probability. Uncertainty analysis also showed that the likely range of the unit production cost for biodiesel is $US0.41/kg-biodiesel to $US0.71/kg-biodiesel at 95% probability. The results that were obtained in this study therefore provide evidence of both the environmental sustainability and the economic viability of biodiesel production from dissolved air flotation sludge via the proposed integrated process of in-situ hydrolysis and esterification.
