“…The efficiency of gas stripping depends on the flow rate, level of foam, and the presence of other components in fermentation broth (Xue et al 2014). The highest butanol selectivity was obtained when gas stripping was performed at 67 °C (Abdehagh et al 2013). Although batch, fed batch, and continuous fermentation can be coupled with in situ product removal, continuous fermentation had the highest beneficial effect.…”

“…For every ton of butanol recovered from a 2% broth, 6 tons of steam are required (Abdehagh et al 2013) (In this article, metric units are used throughout, and the term "tons" indicates metric tons). This corresponds to a distillation cost of $54 per ton of butanol assuming the use of a natural gas boiler for steam generation and a natural gas cost of $2.95 per 1000 ft 3 ($2.78 per GJ).…”

“…Therefore, alternative techniques were developed that enable instantaneous product removal from the broth, which not only enriches the concentration of solvent prior to distillation, but allows continuous fermentation by maintaining a low enough titer to reduce the microbial toxicity. Some prominent strategies used for in situ product removal include gas stripping, solvent extraction, and pervaporation (Table 4) (Ezeji et al 2003;Ezeji et al 2010;Dürre 2007;Abdehagh et al 2013). (Ezeji et al 2004;Dürre 2007;Inokuma et al 2010;Baez et al 2011;Abdehagh et al 2013;Xue et al 2014 In gas stripping, nitrogen or fermentation gases are bubbled through the fermentation broth to strip away the products (de Vrije et al 2013;Xue et al 2013b;2014a;2014b;Ezeji et al 2003).…”

“…Biobutanol has more favorable characteristics in comparison to other biofuels such as bioethanol. Butanol has a net heat of combustion (NHOC) close to gasoline; it is less hazardous to handle due to its lower vapor pressure and volatility, and it can be blended with gasoline in any proportion and be used in existing car engines without any modifications [1]- [9]. It is however limited by its low final concentration due to product inhibition.…”

Currently, the analysis of acetone-butanol-ethanol (ABE) broths is performed using both High Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC) for each sample since GC cannot be used in quantifying sugars and HPLC methods are not yet efficient enough to detect all components separately. In this study, a novel method was developed to quantify all main components present in ABE model solutions (acetone, butanol, ethanol, butyric acid, acetic acid, glucose and xylose) using only HPLC. Although the HPLC operating conditions were optimized to obtain the best possible resolution in HPLC chromatograms, it was observed that the peaks for butyric acid, acetone and ethanol overlapped. The same trend was observed for glucose and xylose. Using the asymmetric Gaussian fit, a program was written in MATLAB to detect the overlapped peaks, deconvolute them and calculate the area of each separated peak. The concentrations of each component were then calculated using the areas and the calibration curves for each component. Experimental results show that this method works well for the ABE model solutions and can be used to quantify all components in the solution when there are some overlapped peaks in the HPLC chromatograms.

“…The fermentation products contain acetone, butanol, and ethanol with a volumetric ratio of approximately 3:6:1. Despite the advantages of A-B-E fermentation, the higher costs of separation of butanol from the fermentation broth have prohibited the large-scale industrial production of butanol [5][6][7]. The direct use of the intermediate product (acetone-butanol-ethanol mixture) could be an economical pathway if used for clean combustion.…”

The present investigation deals with the puffing and micro-explosion characteristics in the combustion of a single droplet comprising butanol/Jet A-1, acetone-butanol-ethanol (A-B-E)/Jet A-1 blends, and A-B-E. The onset of nucleation, growth of vapor bubble and subsequent breakup of droplet for various fuel blends have been analyzed from the high-speed images. Puffing was observed to be the dominant phenomenon in 30% butanol blend, while micro-explosion was found to be the dominant one in other fuel blends (blend with 50% butanol or 30% A-B-E or 50% A-B-E). It was observed that puffing always preceded the micro-explosion. The probability of micro-explosion in droplets with A-B-E blends was found to be higher than that of butanol blends. Although the rate of bubble growth was almost similar for all butanol and A-B-E blends, the final bubble diameter before the droplet breakup was found to be higher for 50/50 blends than that of 30/70 blends. The occurrence of microexplosion shortened the droplet lifetime, and this effect appeared to be stronger for droplets with 50/50 composition. Micro-explosion led to the ejection of both larger and smaller secondary droplets; however, puffing resulted in relatively smaller secondary droplets compared to micro-explosion.Puffing/micro-explosion were also observed in the secondary droplets.
