Measuring Carbon Monoxide Gas—Liquid Mass Transfer in a Stirred Tank Reactor for Syngas Fermentation
Carbon monoxide‐liquid mass transfer rates in a water‐filled stirred tank reactor are determined using a myoglobin protein method to measure dissolved carbon monoxide concentrations as a function of time. Data are acquired over a range of stirrer speeds (200 ≤ N ≤ 600 rpm) and gas flow rates (1 ≤ Q ≤ 6 L/min), corresponding to a gas retention time range of 1.2–7 min. Volumetric CO‐water mass transfer coefficients range from 0.003 to 0.043 s−1 and are well‐correlated using the power density and the superficial gas velocity.
