Bioreactor - Wikipedia

Bioreactor - Wikipedia

A bioreactor refers to any manufactured device or system that supports a biologically active environment. In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This process can either be aerobic or anaerobic.These bioreactors are commonly cylindrical, ranging in size from litres .

Comparison of rotating bed reactor (RBR) technology and fixed bed reactor (FBR) column during activated carbon decolourization. The more efficient use of the adsorbent with a SpinChem® RBR enabled completion of the process within 40% of the time at the same material amount or allowed reduction to 50% material while still being able to finish the process within the same time as the FBR.

Pressure Relief Valves - Parr Instrument Company

Spring-loaded relief valves should be viewed as supplements and not substitutes for a safety rupture disc. The rupture disc is the primary means for protection of the operator and the vessel in case of accidental over-pressure. Spring-loaded relief valves can be added to a reactor or vessel to: Relieve pressures near the maximum operating pressure. [.]

Effect of Gas Bypassing in Deep Beds on Cyclone Dipleg .

Bolthrunis (13) found that severe gas maldistribution occurring in a large fluid bed reactor could be prevented by installing baffles. If cyclone diplegs are located in the poorly fluidized region of a gas bypassing bed, solids discharge from the dipleg will likely be hindered, which can lead to the flooding of the dipleg and the cyclone.
