“…The non-random two-liquid (NRTL) thermodynamic method correlates the activity coefficients of one compound with its mole fractions, and the reference methods are NRTL-HOC . The NRTL-RK model is appropriate because the majority of compounds are non-electrolyte polar and the operating pressure is less than 10 bar. − …”

The environmental conditions generated by the consumption of fossil fuels have created a growing interest in alternative energy sources for various sectors of society. In the case of the aviation sector, one solution is biojet fuel as a sustainable fuel for direct application in flights. The alcohol to jet (ATJ) fuel process has high expectations due to its performance and for revalorizing alcohols from fermentation. Starting from ethanol, the ATJ process consists of four stages: dehydration, oligomerization, hydrogenation, and separation. On the other hand, process intensification philosophy promotes process efficiency, reducing the number of equipment used, reducing land use, and combining different phenomenologies. In this sense, this work researches the outlines of implementing intensification ideas to the ATJ process using reactive distillation (RD) to improve the sustainable performance of jet fuel production. Particularly, the oligomerization and hydrogenation stages will be subject to process intensification strategies. Both strategies were evaluated considering various sustainability indicators (global warming potential, mass intensity, energy intensity, economic impact, etc.). The most intensified alternative presented is an RD column with two reactive sections. Once a distillation column with two reactive zones was implemented, an improvement in the return on investment value of close to 50% and a decrease in the total annual cost of close to 90% were observed. The global warming potential value improved by 70%. Likewise, an improvement of close to 30% was observed in efficiency, mass intensity, and thermodynamic efficiency.

“…Another major disadvantage for this technology is the high capital upfront required for economic feasibility. The collection facilities from different areas, relatively low heat value and unstable fuel quantity and quality will also incur extra cost and uncertainties of the process [48]. In terms of drop-in performance, the lack of aromatic compounds in FT fuels [49] can lead to fuel leakage problems due to the insufficient swelling…”

“…In the last twenty years, several techno-economic (TEA) studies have been performed on biofuels production from biomass [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]; but just recently, a few studies have focused on the economic analysis of a platform chemical production [ 32 , 33 , 34 , 35 ]. However, no TEA studies have been published on the production of acetic acid via bioconversion from cellulosic biomass.…”

Most of the current commercial production of glacial acetic acid (GAA) is by petrochemical routes, primarily methanol carbonylation. GAA is an intermediate in the production of plastics, textiles, dyes, and paints. GAA production from biomass might be an economically viable and sustainable alternative to petroleum-derived routes. Separation of acetic acid from water is a major expense and requires considerable energy. This study evaluates and compares the technical and economic feasibility of GAA production via bioconversion using either ethyl acetate or alamine in diisobutylkerosene (DIBK) as organic solvents for purification. Models of a GAA biorefinery with a production of 120,650 tons/year were simulated in Aspen software. This biorefinery follows the path of pretreatment, enzymatic hydrolysis, acetogen fermentation, and acid purification. Estimated capital costs for different scenarios ranged from USD 186 to 245 million. Recovery of GGA using alamine/DIBK was a more economical process and consumed 64% less energy, due to lower steam demand in the recovery distillation columns. The estimated average minimum selling prices of GGA were USD 756 and 877/ton for alamine/DIBK and ethyl acetate scenarios, respectively. This work establishes a feasible and sustainable approach to produce GGA from poplar biomass via fermentation.
