The possibility of regenerating the solvent of extraction units by cyclic adsorption was analyzed. This combination seems convenient when extraction is performed with a high solvent-to-impurity ratio, making other choices of solvent regeneration, typically distillation, unattractive. To our knowledge, the proposed regeneration scheme has not been considered before in the open literature. Basic relations were developed for continuous and discontinuous extraction/adsorption combinations. One example, deacidification of plant oil with alcohol, was studied in detail using separate experiments for measuring process parameters and simulation for predicting performance at different conditions. An activated carbon adsorbent was regenerated by thermal swing, making cyclic operation possible. When extracting the acid with methanol in a spray column, feed = 4 L min−1, solvent = 80 L min−1, feed impurity level 140 mmol L−1, and extract concentration 7.6 mmol L−1, the raffinate reaches a purity of 1.2 mmol L−1, the solvent being regenerated cyclically in the adsorber (364 kg) to an average of 0.7 mmol L−1. Regeneration of the solvent by cyclic adsorption had a low heat duty. Values of 174 kJ per litre of solvent compared well with the high values for vaporization of the whole extract phase (1011 kJ L−1).

“…Phosphorus, calcium and magnesium are minor components typically associated with phospholipids and gums which may act as emulsifiers or cause sediment as well as lowering yields during the transesterification process [81]. According to ASTM D6751 standard, the phosphorus content in biodiesel must be less than 10 ppm, and calcium and magnesium combined must be less than 5 ppm.…”

Reusing biomass waste is one objective of environmental sustainability and has turned into a choice to increase the value of producers. Biosorbent, the most fitting illustrative of biomass waste, is as of now acquiring adequate attraction, because of its convenience and potentiality in protection of nature. Affirming the statement, this article presents a cutting‐edge review of different biosorbents in dry cleaning of biodiesel impurities. Moreover, the progress on the preparation of these biodegradable adsorbents, their formidable challenges in concert with the future prospect, has been featured and discussed. Finally, the examination of biomass‐derived adsorbents in the area of adsorption science and technology represents a possible alternative, prompting the widespread change of pollution control. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13077, 2019
