background
A new material technology company located in the southern region of China is expanding a set of pyrrolidone series production facilities. The main construction contents include acetylene drying unit, catalyst preparation unit, alpha pyrrolidone unit, N-vinyl pyrrolidone unit. The project's water supply, power supply, heating, cooling and circulating water and other public works rely on the existing public works in the factory area.
Measurement requirements
The flow meter of this project needs to measure the alpha pyrrolidone unit, drying workshop, N-vinyl pyrrolidone unit, power workshop, external lines, low-pressure steam, medium pressure steam, high-pressure steam, heat transfer oil, as well as ammonia water, hot water, circulating water, chilled water, sodium hypochlorite, fire water, etc. The pipeline diameter is between DN20-DN100, requiring accurate flow measurement and stable product performance. Before the flowmeter leaves the factory, it must obtain certification from a high-precision real flow calibration device to ensure its accuracy. In addition, maintenance free is also required.
Xun'er Solution
After on-site investigation and communication of the Xun'er selection project, the temperature pressure compensation integrated vortex flowmeter is used for measuring steam and nitrogen on site, measuring thermal oil, and measuring NVP solution liquid in the drying room cold water and circulating water. The vortex flowmeter without temperature pressure compensation function is used for liquid measurement. To ensure the safety of the application, all vortex flowmeters are equipped with explosion-proof function and adopt IP65 protection level, 304 body and 316 probe, meeting the customer's maintenance free requirements.
For the measurement of sodium hypochlorite, water, and acetylene in the acetylene workshop, as well as for the measurement of conductive liquids such as ammonia water, hot water, and circulating water in the alpha pyrrolidone unit, explosion-proof electromagnetic flow meters are used. For the acidity and alkalinity of the medium, PTFE lining and rubber lining, tantalum electrodes, and 316L electrodes are equipped respectively.
Customer benefits
The stability of the Xun'er flow meter is high. Since installation, customers have provided feedback that the meter can maintain accurate measurement under high temperature, high pressure, and medium changes, greatly reducing maintenance workload and improving overall production efficiency.In production areas involving flammable and explosive substances, explosion-proof design ensures the safety of production. At the same time, the IP65 protection level ensures the normal operation of the instrument in harsh environments, effectively resisting external factors such as water and dust, and further ensuring production safety.
