Kinetics of wax deposition and its movement in a pipeline

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Summary

  1. 1.

    An electrical analog has been used in studying the thermal processes involved in crystallization of a wax melt as it moves within a short section of a pipeline.

  2. 2.

    Temperature profiles have been obtained for the crystalline wax layer, cylindrical in form, at various moments of time.

  3. 3.

    Effects have been determined for the withdrawal of heat to the cooling agent (α a and ta) and the supply of heat from the superheated melt (Δtm and w) to the phase boundary, in relation to the formation of the crystalline wax layer.

  4. 4.

    It has been shown that the pipeline diameter affects the change in open area.

  5. 5.

    Good agreement has been obtained for the limiting values of the crystal-layer thickness as calculated from the proposed analytical formula (7) and as found by means of the electrical analog.
