Lactic Acid from Glucose (Speculative Low pH Continuous Fermentation)
Lactic Acid Operating Costs & Plant Construction Costs
This report presents the economics of Lactic Acid production from glucose syrup using a speculative, continuous, low pH, fermentation process in the United States. In this process, Lactic Acid is recovered from the fermentation broth through microfiltration and nanofiltration steps, generating an 80 wt% Technical Grade Lactic Acid, with 95 wt% purity.
The report provides a comprehensive study of Lactic Acid production and related Lactic Acid production cost, covering three key aspects: a complete description of the Lactic Acid production process examined; an in-depth analysis of the related Lactic Acid plant capital cost (Capex); and an evaluation of the respective Lactic Acid plant operating costs (Opex).
The Lactic Acid production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Lactic Acid plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Lactic Acid plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises two major sections: (1) Fermentation; and (2) Product Separation.
Fermentation. The culture media used in the fermentation is prepared by diluting glucose (fermentable carbon source) and nutrients (comprised mainly of yeast extract as sources of vitamins and nitrogen). Such media is heat sterilized at 121 °C for 30 min. Then, the media is cooled to about 35 °C and fed continuously to fermentation. Lactic Acid is produced by fermentation of glucose using 'Lactobacillus rhamnosus', a homolactic organism. The fermentation is carried out in a continuous membrane based fermentation system, at temperatures ranging between 25 and 40 °C, and uncontrolled pH.
Product Separation. A continuous broth stream is withdrawn from fermenter and passed through microfiltration and nanofiltration steps. In the microfiltration step, cells are retained and recycled to the fermentation. The nanofiltration step separates Lactic Acid from unconverted sugar, which are also recycled to the fermenter. Finally, the Lactic Acid solution from nanofiltration is subjected to an evaporation step and an 80 wt% Lactic Acid with 95 wt% purity is obtained.
