Control of the mixing time in vessels agitated by submerged recirculating jets
Submerged recirculating jet mixing systems are an efficient and economical method of agitating large tanks with a high hydraulic residence time. Much work has been carried out in developing design correlations to aid the predictions of the mixing time in such systems, with the first such correlation being developed nearly 70 years ago. In most of these correlations, the mixing time depends dire...
متن کاملComparison of non-agitated and agitated batch, thermophilic anaerobic digestion of sugarbeet tailings.
Sugar beet tailings were anaerobically digested at non-agitated and agitated conditions in identical thermophilic batch reactors. The average methane yield in the agitated digester was only 74% of that in the non-agitated digester. Ninety percent of the ultimate methane yield was produced in approximately 5 days in the non-agitated digester whereas it took 12 days in agitated digester. Even upo...
متن کاملOxygen transfer and mixing in mechanically agitated airlift bioreactors
Gas holdup, mixing, liquid circulation and gas–liquid oxygen transfer were characterized in a large (∼1.5 m3) draft-tube airlift bioreactor agitated with Prochem® hydrofoil impellers placed in the draft-tube. Measurements were made in water and in cellulose fiber slurries that resembled broths of mycelial microfungi. Use of mechanical agitation generally enhanced mixing performance and the oxyg...
متن کاملSolutions to Batch Mixing Issues
Inefficiencies in batch mixing operations manifest themselves in a number of ways such as long cycle times, frequent reworks, defects or low product quality, difficulties in maintaining temperature, losses in raw material or finished product, and intensive clean-up, to name a few. This white paper presents some strategies for improving commonly encountered batch mixing problems. Because mixing ...
متن کاملa review on the jet mixing in vessels
mixing is an important unit operation in many chemical engineering applications. nowadays, the jet mixing is widely used and going to be replaced with conventional mixers as a result of its simplicity, high performance and low costs. jet mixing in tanks has been investigated by many researchers. however, no comprehensive literature review exists. in the present review detailed investigation of ...
