Abstract
Sposób wyznaczania temperatury depozycji stałej fazy parafinowej w ropie naftowej charakteryzuje się tym, że odpowietrzony ciśnieniowy układ (11) wraz z komorą (1), poprzez układ połączeń ciśnieniowych (11), napełniono z pojemnika ciśnieniowego (10a) separatorowym gazem a następnie przez układ połączeń ciśnieniowych (11) z pojemnika ciśnieniowego (10b) do komory (1) wtłoczono separatorową ropę i uruchomiono mieszanie próbki za pomocą magnetycznego mieszadła, a następnie w łaźni termostatycznej (8) włączono grzanie przygotowanego układu ropa-gaz do temperatury wyższej od depozycji stałej fazy parafinowej i podnoszono ciśnienie w komorze (1) do wartości ciśnienia panującego w warunkach rzeczywistych, jednocześnie monitorując utrzymywanie zadanego ciśnienia w układzie (1), a po uzyskaniu stabilizacji temperatury, w której próbkę nasyconą gazem utrzymywano w zadanych warunkach ciśnienia i temperatury przez okres 90 min, ciągle mieszając, aż do osiągnięcia stabilizacji fazowej, wyłączono mieszanie i wytłaczano do pojemnika tłokowego nadmiarowy" gaz, który w danych warunkach ciśnienia i temperatury nie zdołał rozpuścić się w próbce ropy, a następnie tak przygotowaną nasyconą gazem próbkę, przetłaczano przez kapilarę (3) zanurzoną w układzie kriostatycznym, rejestrując online opór przepływu w zadanej temperaturze przez czas 5 minut, jednocześnie utrzymując stałą temperaturę 50°C w obu komorach ciśnieniowych (1) i (2), a po wykonaniu pomiaru w nastawie kriostatu obniżano temperaturę o 1°C i stabilizowano przez 15 minut, po czym próbkę ponownie przetłaczano przez kapilarę (3) zanurzoną w układzie kriostatycznym, rejestrując opór przepływu w obniżonej temperaturze przez czas 5 minut, i czynność tę powtarzano, zmniejszając temperaturę o 1°C do chwili pojawienia się wzrostu oporów przepływu przez kapilarę (3), a po przyroście oporów dokonuję się trzech kolejnych pomiarów i na końcu, po wykonaniu serii pomiarowej w zadanym ciśnieniu, próbkę ponownie przetłaczano bajpasem (9) do komory tłoczącej z możliwością przygotowania próbki dla innej wartości ciśnienia nasycenia ropy i wykonania kolejnej serii pomiarowej."The method for determining the deposition temperature of the solid paraffin phase in crude oil is characterized by the fact that the deaerated pressure system (11) together with the chamber (1) is filled with separator gas from the pressure container (10a) through the pressure connection system (11) and then through the connection system. pressure vessels (11) from the pressure container (10b) into the chamber (1), the separator oil was pumped and the sample was mixed using a magnetic stirrer, and then the prepared oil-gas system was heated in the thermostatic bath (8) to a temperature higher than the deposition of the solid paraffin phase and the pressure in the chamber (1) was increased to the pressure prevailing in real conditions, while monitoring the maintenance of the set pressure in the system (1), and after achieving temperature stabilization, in which the sample saturated with gas was maintained at the set pressure and temperature conditions for a period of 90 min, while stirring continuously until phase stabilization was achieved, the mixing was turned off and the "excess" gas was extruded into the piston container, which failed to dissolve in the oil sample under the given pressure and temperature conditions, and then the gas-saturated sample prepared in this way was forced through the capillary (3) immersed in the cryostatic system, recording online the flow resistance at a given temperature for 5 minutes, while maintaining a constant temperature of 50°C in both pressure chambers (1) and (2), and after the measurement in the cryostat setting, the temperature was lowered by 1°C and stabilized for 15 minutes, then the sample was again forced through the capillary (3) immersed in the cryostatic system, recording the flow resistance at a reduced temperature for 5 minutes, and this activity was repeated, reducing the temperature by 1°C until the flow resistance through the capillary increased. (3), and after the resistance increases, three further measurements are made and finally, after performing a measurement series at a given pressure, the sample is again pumped through the bypass (9) into the pumping chamber with the option of preparing the sample for a different value of oil saturation pressure and performing another measurement series "
