A new type of crude oil freezing point measuring device and its measuring method

Abstract

The invention relates to a novel crude oil condensation point measurement device and a measurement method thereof. The novel crude oil condensation point measurement device comprises an X-ray emission device, a real-time image receiving and processing device, a tank body, a liquid tank, a condensation point test tube, a rotation driving device and a computer terminal control platform, wherein the liquid tank is located between the X-ray emission device and the real-time image receiving and processing device, and the real-time image receiving and processing device is connected with the computer terminal control platform; a temperature sensor is fixed in the condensation point test tube, and another temperature sensor is fixedly mounted in the liquid tank; the two temperature sensors are connected with corresponding signal converting and processing devices which are respectively connected with corresponding data acquisition cards, and the two data acquisition cards are both connected with the computer terminal control platform; the X-ray emission device, the rotation driving device and a heating-refrigerating liquid circulator are all connected with the computer terminal control platform. The novel crude oil condensation point measurement device and the measurement method thereof improve the condensation point measurement accuracy.

Description

technical field [0001] The invention relates to a measuring device for the freezing point of petroleum products, in particular to a measuring device for the freezing point of crude oil, additive modified crude oil and crude oil emulsion and a measuring method thereof. Background technique [0002] The freezing point is an important indicator of petroleum products, and the measurement of the freezing point is of great significance to the use, storage and transportation of petroleum products. Condensation point is one of the main basic physical parameters in the design and calculation of crude oil pipeline transportation. The accuracy of its measurement is not only related to the energy saving and consumption reduction of petroleum product storage and transportation, but also an important basis parameter for its flow safety guarantee. [0003] When using the existing petroleum freezing point tester to measure the freezing point of additive modified crude oil, it is found that ...
