摘要：

An engineering study was conducted to evaluate the engineering economics of producing calcium magnesium acetate (CMA), using different kinds of residue biomass as feedstock (sewage sludge, biomass, municipal solid wastes, industrial wastes etc.). This study focused on bioconversion of cellulose (as a model organic) to CMA based on 'suppressed methane' fermentation of the organic residue to produce acetic acid, followed by liquid ion exchange to recover the acetic acid from the fermenter broth, with subsequent reaction with dolime to form CMA, which is dried to a white crystalline salt. Preliminary economic analysis revealed that the base line production cost for CMA was $358 (metric) tonne ($325 per US ton). However, with the assumption of a 'credit' for the disposal of the residue biomass, CMA can be more competitive. For example, it was found with a credit of $1210 per t ($1100 per US ton) for disposal of sewage sludge, the costs result in a plus $825 per t ($750 per US ton) CMA produced.
