The Citric Acid Plant Of Yearly10000Tons Produced

The citric acid is the important industrial chemicals which food and the chemicalindustry must be needed and widely applied in food and the chemical industry. Ourcountry’s citric acid output amounts to500,000tons, the citric acid and the citrateexport total approximately are400,000tons, and the yearly average export growth is20%³0%. Along with the world economy’s development and the improvement of thestandard of living, the citric acid market demand also in the swift growth, therefore, thecitric acid market speaking of the world has the big development potential. In thisproject the corn, a raw material carries on the fermentation after smashing,liquefication. The corn dregs’s reuse reduced the production cost greatly. Moreover,taking the corn as raw material may cause the waste water.The organic pollutantdensity also large scale reduced. In the extraction construction section, this project usesdomestic advanced “Absorption exchange” extraction.Extraction receiving rateenhances from original75%about to80%, which improved the product quality,reduced the production cost.The production realizes the automatic routine control, eliminates production waste-CaSO₄, and saves the energy consumption. After the calculation, this project mayproduce citric acid10000t, corn dregs400t, mycelium680t,（NH₄）₂SO₄580t each year,the year creates the income30,915,000Yuan, the recycling contract is4years. In brief,this project conforms to the sustainable development principle and promotingprovincial economy development, increasing the farmers’ income, so this project hasthe high added value and the investment rate of return project.
