The kinetics of a gas-promoted oil agglomeration process were investigated by monitoring the change in the turbidity of an aqueous particle suspension as the particles were agglomerated with heptane in a closed tank fitted with baffles and an agitator. Measured amounts of air and heptane were added to a suspension of Pittsburgh No. 8 coal under vigorous agitation. The subsequent rate of change of particle concentration was taken to be an indication of the rate of agglomeration. The rate was found to be proportional to the particle number concentration raised to a power and dependent on agitator speed and the amounts of air and oil added.
