Application of Mass Flow Meter in Monomer Metering in PVC Production

Abstract: The application information of mass flow meter in the monomer metering of PVC production is provided by excellent flow meter and flow meter manufacturers. Abstract: The quality and application in PVC chemical enterprises are widely used. The quality of PVC products is closely related to the flowmeter. This paper mainly introduces its application in production through the principle and improvement of the flowmeter. Today, PVC chemical companies generally use mass flow. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application article details of mass flowmeters in the monomer measurement of PVC production. The quality and application in PVC chemical enterprises are relatively extensive. The quality of PVC products is closely related to the flowmeter. This article mainly introduces its application in production through the principle and improvement of the flowmeter. Nowadays, PVC chemical companies generally use mass flow meters for feeding measurement, and one of the most typical links is monomer feeding. In the mature PVC automatic production process, the monomer is usually pumped out by the pump and then pumped into the polymerization kettle. The monomer feed needs to be metered by two flow meters in series, one of which is used to measure the amount of monomer added to the polymerization tank, and the other is used to correct the metering of the former. If the two tables reflect a maximum allowable error of more than 1.5% of the total charge, the table needs to be corrected. The quality of PVC products is closely related to the accuracy of monomer input. If the amount of monomer injected into the kettle exceeds the error range required by the process, the product will be unqualified, which will cause serious economic losses; on the contrary, the smaller the error of the amount of monomer added to the theoretical standard value, the more high-quality products can be produced. ,Improve economic efficiency. Therefore, the monomer feeding process of PVC production is usually measured by a high-precision mass flow meter that can directly measure the quality. Xinyi Jiatai Chemical Plant has been engaged in PVC production for many years. Originally, a metering tank was used for monomer metering [as shown in Figure 1]. In the technical transformation project of monomer feeding at the end of 2005, two DN80 mainland mass flowmeters were selected. The monomer feeding model after the technical transformation is as follows [Figure 2]: Figure 1 and Figure 2 can be seen from the schematic diagram, the original device uses a metering tank for monomer feeding measurement, and after the improvement, a mass flow meter is used to replace the metering tank. After the technical transformation, there are at least the following advantages: 1. The production efficiency is greatly increased. When measuring with a measuring tank, there are many operation steps, long feeding time, and low production efficiency; using a flowmeter not only realizes the automatic measurement of monomer quality, but also enables real-time online control of parameters such as flow rate, thereby greatly improving production efficiency. Second, the measurement accuracy is greatly improved. The surface area of ​​the measuring tank is large, and the slight deviation of the liquid level reading may lead to a major deviation in the total measurement, which will lead to unstable or even unqualified product quality, resulting in major economic losses; the comprehensive error of using a mass flow meter is only 0.2%, It provides a reliable guarantee to ensure the accuracy of the total amount of monomer feed, and also provides a strong technical guarantee for the production of high-quality products, and the economic benefits are bound to be greatly improved. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
