“…The NRTL-HOC (Non-Random Two Liquids with Hayden O'Connell correlation) model was used for the vapour-liquid equilibrium (VLE) in all cases. This model was used in a number of studies simulating the VLE of SCOAs, e.g., [19,20].…”

Anaerobic fermentation (AF) to produce sustainable short-chain organic acids (SCOAs) has found no commercial application so far. This is due to several limitations, including the high energy consumption of the SCOAs’ separation from water by distillation. This study used AspenPlus simulations to investigate the benefits of reverse osmosis (RO) to remove water and concentrate the SCOAs from AF before their separation by distillation. The effect of RO on distillation reflux ratio, heat energy requirements, column diameter and equipment costs was simulated for the processing of model SCOA-containing streams, representing AF effluents. A total of 90 simulations were carried out, investigating three different SCOA compositions, corresponding to different ratios of lactic, acetic and propionic acids, three different concentrations of the total SCOAs (10, 50, 100 g/kg in the stream entering RO) and different extents of water removal by RO. RO brought a reduction in the distillation reboilers’ duty of up to more than 90%, with a reduction of column diameter of up to more than 70%. The total energy consumption, equipment cost and NPV (net present value) of the RO plus distillation process were in all cases more favourable than for the process without membranes.

“…Lactic acid is the most important hydrocarboxylic acid (Wang et al 2016a), and it has a wide variety of applications such as in pharmaceutical products, cosmetics, food industry, package industry, chemistry, and medical areas (Komesu et al 2014a). However, the versatility of applications can only be fully exploited if the compound has a cost-effective production (Komesu et al 2016). The greatest challenge in its production is to obtain high purity lactic acid, which is related to downstream processes (Pal et al 2009).…”
