(a) What is the oxygen demand for acetic acid production in this crop? (b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?
The chemical reaction equation for the conversion of ethanol (C2H5OH) to acetic acid (CH3COOH) is:
C2H5OH + O2 → CH3COOH + H2O
In a vinegar production industry, acetic acid is produced from ethanol during the growth of the bacterium Acetobacter aceti, whose cellular composition is CH1,8O0,5N0,2. The biomass yield from substrate is 0.14 g/g, while the product yield also from substrate is 0.92 g/g. Ammonia is used as a nitrogen source. Based on this information, answer:
(a) What is the oxygen demand for acetic acid production in this crop?
(b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?
