“…One of the primary disadvantages of electrodialysis is the electricity requirements, which can result in high processing costs. For example, studies have indicated that the power requirements for lactic acid separation using electrodialysis can vary from 0.21 to 0.71 kWh/kg acid produced under optimized conditions for maximum lactate recovery [160,161]. However, even with the membrane fouling problems and electricity requirements, electrodialysis has shown significant promise (through improvements in membrane quality) in in situ extraction of carboxylic acid from fermentation broths [133,159].…”

Biochemical Production and Separation of Carboxylic Acids for Biorefinery Applications

Carboxylic acids are traditionally produced from fossil fuels and have significant applications in the chemical, pharmaceutical, food, and fuel industries. Significant progress has been made in replacing such fossil fuel sources used for production of carboxylic acids with sustainable and renewable biomass resources. However, the merits and demerits of each carboxylic acid processing platform are dependent on the application of the final product in the industry. There are a number of studies that indicate that separation processes account for over 30% of the total processing costs in such processes. This review focuses on the sustainable processing of biomass resources to produce carboxylic acids. The primary focus of the review will be on a discussion of and comparison between existing biochemical processes for producing lower-chain fatty acids such as acetic-, propionic-, butyric-, and lactic acids. The significance of these acids stems from the recent progress in catalytic upgrading to produce biofuels apart from the current applications of the carboxylic acids in the food, pharmaceutical, and plastics sectors. A significant part of the review will discuss current state-of-art of techniques for separation and purification of these acids from fermentation broths for further downstream processing to produce high-value products.

“…Membranes used in electrodialysis are polymeric, non-porous, and have a thickness between 10 and 500 m (Porciúncula 2007). Electrodialysis is applied to remove salts from solutions or to concentrate ionic substances (Hábová et al 2004). A special type of configuration is electrodialysis with bipolar membranes.…”

Lactic acid is an important platform chemical with a wide range of applications. Production of lactic acid by fermentation is advantageous because renewable and low cost raw materials can be used as substrates. After fermentation, the broth needs to be purified to obtain pure lactic acid for further uses. Thus, efficient downstream processes are very important because they account for 50% of the production costs. This review discusses different processes that are currently employed for lactic acid recovery, focusing on precipitation, solvent extraction, and separation with membranes. Advances in such recovery processes and drawbacks that limit the application of these technologies at the industrial level are also presented.

“…However, due to fouling of the membranes by bacteria [139,140], a more favorable solution is coupling conventional ED for salt concentration in the brine and removal of non-ionic species with an ED-based process to convert salt to acid and recovery of the base [135,[141][142][143][144][145][146]. Such a solution improves synthesis efficiency, reduces the environmental impact by eliminating wastes and assures longer lifetime of membranes, especially of costly BPMs.…”

“…However, BMED is the most widely used membrane technique for this purpose, and some pilot and commercial industrial plants are currently under operation worldwide, mostly to recover acids from fermentation broths [18,159]. BMED was also demonstrated to be effective in recovery of lactic acid [160][161][162][163][164][165][166], citric acid [167][168][169][170][171][172]191], fumaric acid [173] from fermentation broth, but also in salts conversion in the following acids: formic acid [174,175], acetic acid [176,177], gluconic acid [172,192], p-toluenesulfonic acid [178], salicylic acid [179], ascorbic acid [180,181], lactobionic acid [182], aminoacids [183] and morpholine [184]. The above processes encounter typical obstacles characteristic of BMED: proton and hydroxyl leakage through monopolar IEMs, and ion leakage through BPM.…”

Abstract:The applicability of ion-exchange membranes (IEMs) in chemical synthesis was discussed based on the existing literature. At first, a brief description of properties and structures of commercially available ion-exchange membranes was provided. Then, the IEM-based synthesis methods reported in the literature were summarized, and areas of their application were discussed. The methods in question, namely: membrane electrolysis, electro-electrodialysis, electrodialysis metathesis, ionsubstitution electrodialysis and electrodialysis with bipolar membrane, were found to be applicable for a number of organic and inorganic syntheses and acid/base production or recovery processes, which can be conducted in aqueous and non-aqueous solvents. The number and the quality of the scientific reports found indicate a great potential for IEMs in chemical synthesis.
