Purification of Ammonium Carbonate Solution Using Ceramic Membrane in the Production of Ammonium Sulfate in Uremia Petrochemical Company

One important application of the membrane technology is in solid particles separation from suspension. Recently, Ceramic membranes have been investigated significantly due to it,s advantages such as high mechanical strength, high thermal and chemical stability, etc. In this work, for the first time, the ceramic membrane has been used for solid particles separation of ammonium carbonate as a feed-in Uremia Petrochemical. The experimental results showed that the rejection factor reduced (less than 10%) with increasing temperature and pressure difference. Also, enhancing of rejection factor (up to 97%) and reducing of permeated flux (less than 0.5 cc/min) was observed for at a long time due to cake formation on the ceramic membrane. After 30 min washing with pure water, the used membrane at a long time was regenerated. So, the results confirmed the high potential of the ceramic membranes in solid particle separation of ammonium carbonate.
