Liquid liquid centrifugal extractor used in organic acid fermentation extraction
2026-02-12
A four-stage countercurrent centrifugal extraction system (flow rate 0.8m³/h) uses trialkylamine (N235) as the extractant, achieving a citric acid extraction rate of 94%, reducing solvent residue from 2.1% to 0.6%. Back-extraction and crystallization: After back-extraction of the supported organic phase with sulfuric acid, high-purity citric acid crystals (purity ≥99.5%) are obtained through evaporation concentration and centrifugal crystallization....
