The annual output of 3000 tons of lactic acid production workshop

process design矚慫润厲钐瘗睞枥庑赖。 Abstract Lactic acid is one of the three organic acids which is widely used in the world. This design reviewed the production technology of lactic acid and its prospects for development both at home and abroad were. In production technology for a variety of lactic acid after detailed comparison, I chose the diastatic fermentation production process. Through the material balance, heat balance, main equipment design, selection of auxiliary equipment and layout of the plant, I’m done the annual output of 3000 tons of lactic acid production workshop process design，map the main equipment and process flow diagram and workshop layout, etc., and probes into the whole process of economic, environmental and safety evaluation, which shows that it’s an economic and reasonable process design.
