Abstract:
Recycle streams in an ethanol production process are hydrolyzed to reduce ethyl acetate concentration. In the process, acetic acid is hydrogenated to form a crude ethanol product, which undergoes a separation or purification process. Ethyl acetate is formed as a byproduct of the hydrogenation of acetic acid. The hydrolysis of recycle steams from the separation process can reduce the concentration of ethyl acetate, converting some or all of the ethyl acetate to acetic acid and ethanol.
