Abstract

The invention belongs to the field of flow detection and control in the fields of petroleum, chemical industry, food, environmental protection, etc. using supercritical carbon dioxide, and in particular relates to a supercritical carbon dioxide flow measurement method and a flowmeter. The pressure P in the pipeline is measured by a pressure sensor, and the temperature sensor Measure the temperature T of the liquid in the pipeline, and measure the recoil force on the sensor when the gas, liquid, and solid fluids flow through the jet recoil sensor, measure the recoil force, impact angle, and jet diffusion curve, and calculate the pressure P and temperature T Its mass flow rate solves the flow mass measurement problem of supercritical carbon dioxide multiphase mixing and mutual transformation.

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, etc. 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 technology, supercritical carbon dioxide is used in more and more fields such as petroleum and chemical industry. [0003] Because of its low cost, elimination of carbon emissions, comprehensive utilization and recovery, and its super permeability and various chemical properties, it has a wide range of new applications in oil recovery, drilling, and chemical processes, and brings good economic benefits. [0004] The measurement problem of the user department has not been solved. Whether it is measurement charges or control of process parameters and other important links, accurate measurement is required for other work....
