From batch to continuous extractive distillation using thermodynamic insight: class 1.0-2 case B [PDF]

, 2011
A systematic feasibility analysis is presented for the separation azeotropic mixtures by batch and continuous extractive distillation. Based on batch feasibility knowledge, batch and continuous separation feasibility is studied under reflux ratio and ...

Elevated butanol and acetone bio-production with integrated co-extraction in lime-buffered fermentation using high cell concentration

Case Studies in Chemical and Environmental Engineering
Butanol and acetone bioproduction face inhibition from excessive substrates, leading to acid crashes. Buffering stabilizes acidity and aids product formation, whereas simultaneous extraction prolongs cell productivity. This study aimed to enhance butanol

A novel extractive fermentation process for lactic acid

, 1989
In order to produce lactic acid directly with high productivity, we have developed a novel extractive fermentation process combining lactic acid production by two-step pH manipulation and extraction of lactic acid by poly(4-vinylpyridine) resin.

Solvent-based approaches to evaluate the ABE extractive fermentation [PDF]

, 2019
The reindustrialization of ABE fermentation is hampered by significant production costs, linked to high product inhibition and limited intrinsic yield. The reduction of these costs depends on the effective application of integrated toxic product removal ...

Extractive fermentation of clavulanic acid by Streptomyces DAUFPE 3060 using aqueous two-phase system

, 2011
The influence of four variables, specifically polyethylene glycol (PEG) molar mass (400, 1,000, and 8,000 g/mol), concentrations of PEG and phosphate salts (15, 20, and 25% for both), and agitation intensity (110, 150, and 200 rpm), on clavulanic acid ...

Non-linear predictive control of an extractive alcoholic fermentation process

, 2015
In this work a SISO non-linear predictive controller was developed for an extractive alcoholic fermentation process. The internal model of the controller was represented by a functional link network (FLN).

Dynamic modelling, simulation and optimization of an extractive continuous alcoholic fermentation process

, 2015
The conventional alcoholic fermentation is a typical inhibitory process, leading to low productivity and yield. The ethanol produced inhibits yeast cells, causing a reduction in the alcohol production rate and cell growth rate.
