In the Process Industry, many chemical
reactions are carried out between liquids / slurries and gases,
Traditionally, such gas-slurry reactions have been carried
out with the help of equipment, where basically, an agitator
was used to stir the liquid in the Reactor. This somewhat
clumsy method resulted in less than satisfactory performance,
due to non-ideal mixing, which led to poor catalyst suspension,
negligible gas-liquid interfacial areas, as well as low heat
and mass transfer coefficients.
An Omega Kemix Gas - Induction Reactor offers a radial change
from this conventional approach. Instead of churning the liquid
reaction mass, a hollow agitator pumps gases from the head
space to the lowest part of the Reactor vessel, as shown in
the picture. A specially designed impeller vigorously disperes
these gases into the reactor bottom, resulting in a mixture
akin to a boiling liquid. Gas bubbles react with liquid/slurry
as the as they rise. Unreacted gases are re-inducted into
the liquid.
The self-aspiration agitator of an Omega Gas-Induction Reactor
has a highly efficient design, which leads to the following
advantages:
Vigorous Gas Liquid mixing
Thorough suspension of solid components (e.g Catalyst)
Large gas-liquid interfacial areas (Typical, interfacial
area is 100 to 300 m2 pm3 of operating
volume)
Enhanced Gas-Liquid and Liquid Mass Transfer rates
Very high vessel side heat transfer coefficients, which
approach boling coefficients
Reduced Bath times
Minimal side reactions
Excellent Bath-to-Bath Repeatability
