In the wave of transformation towards intelligent and efficient operations in the coal chemical industry, accurate and reliable instrumentation is the core foundation for stable process operation. In a methanol technical upgrade project of a large coal chemical company, YIGEQI provided a customized pressure measurement solution, empowering the traditional coal chemical industry's upgrade with professional technology. Project Background: The coal gas-water separation section is a key link in the methanol production process. Based on the technical requirements of the project's detailed engineering design, YIGEQI customized pressure transmitter solutions for both venting and coal gas-water conditions, perfectly matching process requirements and on-site conditions:
• Pressure monitoring of venting pipelines: This is a core control point to ensure the safety of process system depressurization and prevent overpressure risks;
• Pressure/level measurement of coal gas-water media: This requires handling conditions containing impurities and high-temperature corrosiveness, placing extremely high demands on the reliability and weather resistance of the instruments.
Solution Analysis: Precise Adaptation of Two Types of Transmitters
Based on the technical parameters of the project's instrument datasheet, the application solution for YIGEQI pressure transmitters is as follows:
Side-mounted Single Flange Pressure Transmitter
For the pressure measurement requirements of the venting pipeline, the project selected the Egerqi side-mounted single-flange pressure transmitter. Its core parameters and advantages are as follows:
These transmitters are installed directly on the venting pipeline to monitor the pipeline pressure in real time, providing accurate data for the safe depressurization and stable operation of the process system. They are the "first line of defense" to ensure the safety of the process section.
Pressure Capillary Single-Flange Level Transmitter
For pressure/level measurement of gas and water media, the project selected the YIGEQI pressure capillary single-flange level transmitter, which perfectly solved the measurement challenges under complex operating conditions.
The gas-water medium contains impurities and is corrosive. The capillary single-flange structure isolates the process medium through a diaphragm, fundamentally solving the pain points of the operating conditions and ensuring long-term stable and reliable measurement.
Core Advantages of Egertech Transmitters
Full-condition adaptability, meeting the harsh environment of coal chemical industry
For methanol projects facing complex conditions such as explosion-proof, high-temperature, corrosive, and dusty environments, YIGEQI transmitters meet project requirements across all dimensions, from explosion-proof rating, protection rating, material selection to structural design. They are intrinsically safe and explosion-proof certified, adaptable to explosive gas environments, and their IP65 protection rating copes with harsh on-site conditions.
High-precision measurement, enabling process optimization
With a high measurement accuracy of ±0.075%, combined with the HART intelligent communication protocol, accurate pressure data acquisition and remote monitoring are achieved, providing data support for process optimization and energy consumption reduction, and helping projects achieve intelligent production.
Customized solutions, tailored to actual project needs
Based on the technical requirements of the project's instrumentation datasheets, YIGEQI has customized two solutions for air venting and coal gas/water conditions: side-mounted single flange and capillary single flange. This ensures both measurement performance and ease of installation and maintenance, achieving an optimal balance between technology and cost.
Full-process service to ensure project implementation
From technical coordination and solution design to production delivery and on-site commissioning, YIGEQI provides professional services throughout the entire process to ensure that instruments are perfectly adapted to the project's processes and to safeguard the smooth commissioning of the project.
