Abstract:

The peculiarities and conditions of paraffin crystallization in oil are studied by experiment and theory. A new technique for measuring of paraffin crystallization point is developed by the Fotekon fluid analyzer. The P-T diagram of the gas-oil-paraffin ternary system, which allows determining the PT region of stable paraffin in oil, is built by the methods of physical and mathematical modeling. The theoretical estimates are in agreement with the results obtained in the experimental studies.
