Web1 okt. 2024 · The continuous production of high titres of E coli T3 phages (10 11 PFU mL-1) was achieved using two continuous stirred tank bioreactors connected in series, and a third bioreactor was used as a final holding tank operated in semi-batch mode to finish the infection process. WebFor a mass of liquid Mbatch, at a specific heat, Cpbatch, the heat energy of the fluid, Q, is defined as: Q = Mbatch * Cpbatch * Tbatch (1) where: Mbatch = mass of the batch liquid being heated or cooled, expressed as lbs. Cpbatch = heat capacity of the liquid batch, expressed as Btu/lb.-F. Tbatch = the temperature of the batch liquid at any time,
WebAs shown in Figure 8.9d, the batch (or tubular) reactor is kinetically superior to the continuous stirred tank reactor.2 The batch reactor has a smaller reaction time and can produce the same amount of product faster than the back-mixed one.
