Extractant Systems for Acetic Acid Recovery

Development of Processes for Production of Calcium Magnesium Acetate 

In a demonstration project report (Basu et al. 1999), a process was outlined whereby municipal solid waste (MSW) coal or sewage sludge was converted to syngas (CO, CO2, and H2) by well-known technologies. For example, lignocellulosic biomass may be gasified by the approximate reaction  

Economic projections for a facility to produce 100,000 t/year of CMA from MSW were presented. With no charge or credit for the waste materials used, the operating cost with an included 30 % investment return was estimated at 200/t. This price is less than 28 % of the price of the CMA deicer. 

a detailed process has been developed for the production of CMA from cheese whey lactose (Yang et al. 1999). 

lactiSy in the fibrous bed removed the requirement for purging O2 from the whey medium to allow growth of the strictly anaerobic C. formicoaceticum. Lactococcus lactis is not as sensitive to O2 and removes the residual O2 from the medium.
