Fluorinated refrigerants

Application Challenge:

1. The process media possess complex characteristics, necessitating stringent requirements for wetted materials and sealing components. The production process involves fluorine-containing raw materials, reaction intermediates, and multi-component mixtures; their corrosivity and compatibility with materials fluctuate based on moisture content and temperature. Consequently, instrumentation must be carefully selected—considering wetted materials, sealing structures, and process connections—to mitigate the risks of corrosion, leakage, and measurement drift that could otherwise disrupt continuous production.
2. Raw material supply, reaction temperature and pressure, as well as condensation and distillation conditions, are all interconnected. Fluctuations in feed, variations in heat exchange, or pressure anomalies can impact downstream separation loads and product consistency. Furthermore, certain measurement points may involve gas-liquid two-phase flow or pressure pulsations, placing higher demands on instrument response and measurement stability.
3. Some refrigerants are stored and transported in a liquefied state; changes in temperature or pressure can lead to density fluctuations or localized flashing, complicating the measurement of liquid levels and flow rates. Instrument selection must account for the phase state of the medium, operating pressure, and installation conditions, while also complying with site-specific requirements for explosion protection and environmental ingress protection.

Solution Advantages

1. Based on factors such as the nature of the medium, operating temperature, pressure range, and installation conditions, Micro Sensor provides expert guidance on the selection of pressure, temperature, flow, and level instrumentation. For applications involving corrosive media or unique installation requirements, we offer customized configurations—including specialized wetted materials, diaphragm seals, and process connections—to ensure optimal compatibility between the instruments and the specific operating environment.

2. For processes such as raw material metering, chemical synthesis, condensation/separation, and distillation/purification, we configure appropriate measurement points for pressure, temperature, flow, and level, while also incorporating differential pressure monitoring for filtration or separation equipment. By integrating with on-site control systems, our solutions provide the data necessary for feed regulation, heat exchange management, and operational trend analysis, enabling clients to promptly identify changes in process conditions.

3. To address measurement requirements for storage tanks, pipelines, and filling stations, we carefully select measurement methods and instrument configurations, taking into account variables such as density fluctuations, phase transitions, and installation positioning. We ensure that all selected products meet the necessary regional certification and ingress protection (IP) standards, while also considering requirements for maintenance access and service procedures, thereby supporting the continuous, reliable operation of your facilities.
