Lactic Acid Production from Lactose
Lactic Acid Operating Costs & Plant Construction Costs
This report provides an economic analysis of Lactic Acid production from lactose via a fermentation process in the United States. Lactic Acid purification is carried out using ion exchange resins and product concentration is accomplished by reverse osmosis and evaporation.
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) Purification.
Fermentation. The culture media used in the batch fermentation is prepared by diluting lactose and yeast extract. Such media is heat sterilized and sent to fermentation. The fermentation is carried out in batch mode and under anaerobic process conditions in an agitated, jacketed fermenter. The pH of the fermentation is maintained between 5 and 6. The temperature is controlled between 40 and 50 °C via circulation of cooling water in the fermenter jacket. The lactate concentration obtained in the fermentation broth is about 6 wt%.
Purification. Cells and other insoluble particles are separated from the fermentation broth by ultrafiltration. Subsequently, the inorganic cations and anions are removed from the clarified fermentation broth by treatment on cation and anion exchange resins. The Lactic Acid solution obtained is concentrated by means of reverse osmosis, using an aromatic polyamide membrane. The resulting Lactic Acid diluted solution is evaporated in a triple effect evaporator. The Lactic Acid is concentrated to 50 wt% with purity above 99 wt%.
