Supercritical fluid distribution in a packed column was investigated by measuring the weight loss of a solid in coaxial cylinders where the fluid passed through. Two criteria to make the equilibrium distribution be uniform were suggested: (1) the ratio of the column diameter to the particle diameter is at least 10, and (2) the particle layers are larger than 40 when a point source is used. The radial diffusion model was found to be applicable to describe the flow in a packed column under supercritical operations. The spreading coefficients in this model were evaluated and were observed to be dependent on particle size and flow rate. A correlation is proposed for predicting the spreading coefficients which gives a deviation smaller than 3.0%. |
