By avoiding the use of a conventional heat exchanger, a DCC crystallizer avoids the troublesome problems associated with encrustation on heat transfer surfaces (section 9.5). The coolant in a DCC process can be a solid, liquid or gas, and heat is extracted by the transfer of sensible and/or latent heat (vaporization or sublimation). 

Stream properties required for solving material and energy balance equations and other process calculations are predicted from component properties. The properties of petroleum pseudocomponents can be estimated from their boiling points and specific gravities. The component properties include the molecular weight, critical constants, acentric factor, heat of formation, ideal gas enthalpy, latent heat, vapor pressure, and transport properties. These are predicted mainly by empirical correlations based on experimental data. Many of these correlations are documented in the American Petroleum Institute Technical Data Book (API, 1983).
