Abstract

The invention belongs to the field of detection and control over flow of supercritical carbon dioxide used in petroleum, chemical industry, food, environment protection and the like, in particular to a supercritical carbon dioxide flow measuring method and a flowmeter. Pressure P in a pipeline is measured by a pressure sensor, the temperature T of liquid in the pipeline is measured by a temperature sensor, recoil force to the jet flow recoil force sensor when gas, liquid and solid fluid flows is measured and detected by the jet flow recoil force sensor, measuring is performed by the recoil force, an impact angle and a jet diffusion curve, mass and flow are calculated by the pressure P and the temperature T, and the problem of calculation difficulty about the flow and mass of the supercritical carbon dioxide in states such as multi-phase mixing and mutual transformation is solved.

Description

technical field [0001] The invention belongs to the field of flow detection and control in the fields of petroleum, chemical industry, food, environmental protection and the like using supercritical carbon dioxide, and in particular relates to a supercritical carbon dioxide flow measurement method and a flowmeter. Background technique [0002] With the development of process technology, supercritical carbon dioxide is used more and more in petroleum, chemical and other fields. [0003] Due to its low cost, elimination of carbon emissions, comprehensive utilization and recovery, as well as its super permeability and various chemical properties, it is widely used in new applications such as oil production, drilling, and chemical technology, and brings good economic benefits. [0004] The measurement problem of the user department has not been solved, and the important links such as measurement and charging or control of process parameters need to be accurately measured in orde...
