In a continuous culture at 28°C with ammonia as a nitrogen source, the alginate yield obtained was 4 g/g of oxygen consumed. It is desired to produce alginate at a rate of 5 kg/h. As the viscosity of alginate in water is considerable, the energy related to stirring the broth cannot be neglected, and the fermenter is equipped with a Rushton-type turbine. For satisfactory agitation and aeration speed, the estimated energy requirement is 1.5 kW. Calculate the cooling requirement.arrow_forward
