Integration of the Process for Production of Ethyl Acetate by an Enhanced Extraction Process

The paper presents a study on the performance of conventional plant-producing ethyl acetate from ethanol and acetic acid. Process models were compiled in simulator Chemcad 7. impact key parameters individual installation nodes was examined by sensitivity analysis. Three approaches are presented compared: two classic with different heat duties an improved one. An technological solution, closed circulation extractant as well azeotrope subcooling for better extraction is demonstrated. energy mass balance developed. proposed enhancement technology significantly reduced consumption fresh also offers deep recovery raw materials, i.e., wastewater. We assumed that same relative to strategy 0.531 0.524 t/tproduct (−1.2%), process water 2.18 1.42 (−34.9%), wastewater 2.36 1.61 (−31.8%). By this, total organic loading (TOL), chemical oxygen demand nine times reduced. major advantage achieved through azeotrope, which improves efficiency, making phase enriched acetate. Therefore, product separation node whole system improved.
