The research for resistance and influencing factors of ion exchanger using citric acid extraction
This paper studies the relationship between the rate of resin expansion and the absorption of time and the resin layer height, and the relationship between the fermentation liquid flow and the absorption of time and the resin layer height during extracting the citric acid from the fermentation liquid using fixed-bed ion exchanger. Through the analysis, we obtained that the resin expansion is the main reason led to resin bed resistance, and put forward the improving measures.
