An experimental loop platform for sequential delivery of mixed oil products

Abstract

The invention relates to a product oil sequential conveying experiment circuit platform. The product oil sequential conveying experiment circuit platform is characterized in that the platform comprises an experiment circuit system provided with a detachable experimental data measuring section, an oil supply system, a data acquisition system and an industrial control computer; the experiment circuit system comprises six layers of experiment circuits arranged in a vertical plane and supported by supports, the detachable experimental data measuring section and a switching triple valve set; the input terminal of the first layer of experiment circuit is connected with the output terminal of the oil supply system to serve as an inlet of a first pumping station; the output terminal of the sixth layer of experiment circuit is connected with the input terminal of the detachable experimental data measuring section; and other layers of experiment circuits are sequentially connected and communicated with one another. After an experiment medium in the oil supply system enters the experiment circuit system, the data acquisition system acquires related data of the experiment circuit system and the oil supply system and sends the related data to the industrial control computer for processing, and research related to product oil sequential conveying is achieved. The product oil sequential conveying experiment circuit platform can be widely applied to product oil sequential conveying mixed oil experiment research.

Description

technical field [0001] The invention relates to the field of petroleum pipeline transportation, in particular to an experimental loop platform for sequential transportation of mixed oil products. Background technique [0002] Sequential transportation is the main way of long-distance pipeline transportation of crude oil and refined oil. It uses one oil pipeline to transport several different petroleum products successively. The cost of oil has a significant effect on improving economic benefits. But at the same time, when different oil products are alternately transported in the pipeline, due to the different physical and chemical properties (especially viscosity and density) of the two oil products, a section of mixed oil is inevitably formed on the contact surface of different oil products. The quality of mixed oil generally does not meet the quality index requirements of the product and cannot be sold directly, so it is often treated as waste or downgraded, especially in...

AI Technical Summary

Problems solved by technology

However, this patent has the following technical shortcomings: ① The length of the experimental loop used in this experimental device is not enough to study the change law of the mixed oil after it is fully developed after long-distance transportation

②The experimental device does not avoid the influence of mixed oil passing through the pump and valve on the temperature, concentration and other physical parameters of the oil, and the influence of this effect on the experimental results cannot be ignored

③The experimental device mainly studies the influence of the running length of mixed oil on the physical parameters such as oil temperature and concentration, and the research on the influencing factors of mixed oil is not comprehensive enough
