Industrial liquid flow meters are precision instruments for measuring the flow of liquids, gases and vapors in sealed pipes. As the detecting element is sealed in the detecting body, there is no measured medium, no internal moving parts, no need for on-site maintenance. Therefore, it is highly praised by users and widely used in the measurement management and process control of textile printing and dyeing, petroleum, chemical industry, metallurgy and pharmacy, thermoelectricity, papermaking, fire-fighting and other industries.
Industrial Liquid Flow Meter - Chemical Industry Flow Monitoring
Chemical production involves complex chemical reactions and material transportation, flow as a core process parameter, directly affects:
1, material proportioning accuracy: such as PTA production, each link of raw materials, additives, flow control, to determine whether the reaction is carried out in accordance with the optimal proportion of the yield and quality of products.
2, energy cost control: accurate flow monitoring can avoid waste caused by excessive material delivery, optimize energy distribution, reduce production costs.
3、Safety risk prevention and control: abnormal fluctuations in flow may indicate pipeline blockage, equipment failure, timely monitoring can be early warning, effective prevention and control.
Take ARTang industrial liquid flow meter applied in PTA refining section as an example, the flow control of crude terephthalic acid (CTA) slurry directly affects the effect of subsequent hydrogenation and refining, crystallization and separation, and it is the basis for guaranteeing the purity of PTA to meet the standard.
PTA refining section: ARTang Industrial Liquid Flow Meter
In the refining section of PTA production of XXXX Co., Ltd, ARTang electromagnetic flow meter is deeply adapted to the complex process:
- In the refining section, CTA slurry is transported to the fifth crystallizer preheater by pressurized pumps. Pipeline pressure is high (such as part of the link pressure up to several MPa), and the medium (CTA slurry) high temperature, fast flow rate. Ordinary electromagnetic flowmeter is not enough to withstand pressure, so the company used ARTang C electromagnetic flowmeter, which takes into account the cost and measurement accuracy.
- High-pressure environment fit: CTA slurry in the section of high pressure after pressurization, ARTang electromagnetic flowmeter, the use of high-strength shell and sealing process, high-pressure impact, to ensure long-term stable operation, to eliminate the risk of leakage of media.
- Accurate measurement guarantee: CTA slurry containing solid particles, high temperature, flowmeter optimization of the magnetic circuit and electrode design, with corrosion-resistant wear-resistant lining (such as PTFE), accurately capture the flow signal, even in the complex flow state, the measurement error is still controlled in a very small range for the hydrogenation reaction ratio, crystallization and separation process, to provide reliable data.
Product advantages of ARTang Industrial Liquid Flow Meter
- Accurate flow monitoring ensures stable CTA slurry delivery, accurate material proportioning in hydrofinishing process, effective reduction of 4-CBA and other impurity residues, improvement of PTA product purity, and upgrading of downstream polyester production quality.
- Industrial water flow meters durability, low frequency of operation and maintenance, saving late maintenance costs; accurate flow control to avoid waste of materials, optimize energy consumption, long-term operation can significantly reduce production costs; early warning of flow abnormalities, reduce equipment failure and downtime losses.
- Industrial water flow meter is stable and reliable, to ensure the continuous operation of the refining section; real-time accurate data to support the dynamic adjustment of process parameters, shorten the production debugging cycle, and help release production capacity.
- CTA slurry is high-pressure, particle-containing and corrosive, which is a great test for instrument structure and material. Aiming at the working conditions, ERTANG adopts high-strength stainless steel shell + customized corrosion-resistant and wear-resistant lining and electrode, and passes strict tests to ensure long-term stable operation.
In the refining section of chemical PTA production, ARTang’s industrial liquid flow meter has become an important guarantee for the stable operation of the process with “accurate measurement, reliable adaptation and cost optimization”. From the necessity of flow monitoring, to the in-depth application in complex scenarios, to the breakthroughs in customer benefits and challenges, ARTang uses its technology and services to help chemical companies cope with the financial pressure and production uncertainty, and to make the “precise control, cost reduction and efficiency enhancement” from a goal to a reality.
