Modeling of Wax Crystallization in Production of Lube Oil Base Stock in Solvent Dewaxing

A mathematical model of a steady heat transfer and crystallization was established in double pipe scraped surface heat exchangers and chillers for solvent dewaxing process. The model equations were numerically solved to obtain, the temperatures distribution, wax volume fraction, crystals number and...
