Prediction method for the Paraffinic Wax Crystal Size Distribution in Solvent Dewaxing Process

A steady state 1-D model was implemented for conventional solvent dewaxing unit. The coupled equations for heat transfer and population balance were solved numerically to obtain the wax crystal size distribution, wax volume fraction along a double pipe scraped surface heat exchangers and chillers th...
