DESIGN OF NA INDUSTRIAL PROCESS FO GLYCERIN CARBONATE PRODUCION

Abstract

Biodiesel industries generates large amounts of glycerin what creates a demand for its suitable destination, with a possible transformation into a valuable product. One of these products is the glycerin carbonate. This substance has an increasing market as raw material for cosmetics, drugs, polymers and specilatiy solvents among others. This work shows an industrial process for the production of glycerin carbonate which achieves near complete conversion. The studies wre made with the use of the software Aspen Plus^®. All physical equilibrium properties were calculated by the NRTL method. A process flowsheet with basic control strategy is presented. It has been also made a preliminary economic analysis based on ultilities, raw materials and product costs
