OVERVIEW OF CHEMICAL REACTION ENGINEERING .

Chemical reaction engineering (CRE) is the branch of engineering that encompasses the selection, design, and operation of chemical reactors. Because of the diversity of chemical reactor applications, the wide spectrum of operating conditions, and the multitude of factors that affect reactor .

A cylindrical bioreactor of diameter 3 m has four baffles .

A cylindrical bioreactor of diameter 3 m has four baffles. A Marine. propeller mounted in the reactor has a diameter of one-third the tank diameter. The liquid height is equal to the tank diameter and the density of the fluid is approximately 1 g cm3 . The reactor is used to culture an anaerobic organism that does not require gas sparging.

Reactor - processdesign

In order to manually design a fluidized bed reactor which would yield a useful information, myriads of parameters such as porosity at minimum fluidization, minimum fluidization velocity, bubble size, minimum fluidization velocity, velocity of bubble rise, fraction of the total bed occupied by bubbles, fraction of the bed consisting of wakes, volume of the catalyst in the bubbles, clouds and .

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 .

Mass and Energy Balances

In environmental engineering and chemical engineering, the term Continuously Stirred Tank Reactor, or CSTR is used for such a system. An example of a CSTR is shown in Figure 1 . We will use a mass balance for a control volume which encloses the CSTR in Figure 1 as an example to describe the meaning of each term in equation 14 .
