A Method of Predicting and Controlling the Output Quality of Multiphase Flow System Containing Hot Gas

Abstract

The invention discloses a method for predicting and controlling the discharging quality of a multiphase flow system containing hot gas. The method comprises the following steps: (1) guaranteeing parameters related to the characteristics of the multiphase flow system containing the hot gas, selecting basic parameters and rest parameters to constitute at least five dimensionless parameters, and building at least two relevance forms with corresponding schemes; (2) measuring field data of operational systems; (3) guaranteeing the regressed relevance forms of the discharging quality of the system; (4) verifying the accuracy of the regressed relevance forms, and operating the step (5) if the accuracy is adequate, otherwise, going back to the step (1); (5) controlling corresponding technology parameters required for production by use of the regressed relevance forms and based on the requirement for the accuracy of the discharging quality, and in addition, predicting and controlling the result of the discharging quality by use of the regressed relevance forms and based on the technology parameters. According to the invention, the relevance forms of predicting and controlling the discharging quality of the multiphase flow system containing the hot gas can be acquired by use of lower cost, which is beneficial to lowering running and operating cost and guaranteeing the quality of products.

Description

technical field [0001] The invention relates to a method for controlling the output quality of a multiphase flow system, in particular to a method for predicting and controlling the output quality of a multiphase flow system containing hot gas. Background technique [0002] A flow in which two or more fluids of different phases are mixed together is called a multiphase flow. For the multiphase flow system containing hot gas, there are many parameters involved in the operation process, not only gas, but also solid, but it is necessary to measure parameters such as temperature and flow to evaluate its operating performance. Its outstanding feature is that the parameters involved are not completely independent of each other in dimension. [0003] With the development of the economy, people's pursuit of health, environmental protection and economy has led to an increasing demand for the discharge of the multi-phase flow system containing hot gas. more demanding. With the impr...

AI Technical Summary

Problems solved by technology

When the multi-phase flow system with hot gas is in operation, on-site personnel generally rely on experience or single-factor analysis to evaluate the operating performance of the system. There is a certain degree of blindness. Waste, serious equipment accidents

Especially in the abnormal stage of the system, it is difficult to control the quality of the output material as easily as in the normal operation stage of the system

The reason is that some parameters of the system are adjustment parameters that are difficult to respond quickly, but once their values ​​are set correctly, it will reduce a lot of unnecessary troubles for subsequent operations
