Problems solved by technology

In the actual measurement of volume, the influence of temperature differences is not considered
The most important thing is that without the density data of crude oil, it is impossible to calculate the percentage of distillate volume at each temperature point of the distillation range, which affects the accuracy of crude oil distillation range analysis
At the same time, in order to improve the sensitivity and accuracy of the analysis, the existing detection device needs to use a photoelectric detection initial boiling point system and a photoelectric liquid level tracking system, resulting in cumbersome operation of the crude oil distillation range detection process, long test time, troublesome, time-consuming and laborious

Abstract

The invention relates to a device and technological method for detecting the distillation range of crude oil through a mass method. The device is characterized in that a distillation flask is connected with a temperature tester, a branch pipe of the distillation flask is connected with a condensation pipe, and a condenser is connected to the condensation pipe; the outlet end of the condensation pipe is opposite to a receiver which is placed on an electronic scale. The detection method includes the steps that 100 g of crude oil samples are weighed and placed into the distillation flask; secondly, the distillation flask containing the crude oil samples is heated, the distillation temperature of the crude oil samples is accurately measured through the temperature tester, and the mass of distilled substances is continuously weighed through the electronic scale; thirdly, temperature which is continuously measured by the temperature tester and data of continuous weighing, performed by the electronic scale, of the distilled substances are calculated and processed, and an analysis data result of the distillation range of crude oil is obtained. According to the device and technological method for detecting the distillation range of crude oil through the mass method, the distillation range of crude oil is analyzed in the mode that the crude oil samples and the distilled substances are weighed through the mass method, and therefore analysis of the distillation range of crude oil can be more accurate and faster.

Description

technical field [0001] The invention relates to a device and a process method for detecting the distillation range of crude oil in the technical field of petrochemical industry, in particular to a device and a process method for detecting the distillation range of crude oil by mass method. Background technique [0002] The distillation range refers to the temperature corresponding to the volume of each distillation range from the initial boiling point to the final boiling point when the petroleum product is distilled under standard conditions. Crude oil distillation range analysis is the most important testing item for crude oil. The results of distillation range analysis are important basic parameters for oilfield exploration, development, storage and transportation, refining and processing departments to evaluate the properties of crude oil. The existing national standard "GB / T26984-2011 Crude Oil "Determination of Distillation Range" is formulated on the basis of the B me...
