Successful Application Cases of SUP-P300 Pressure Transmitter in the Petrochemical Industry

Under the harsh operating conditions of the petrochemical industry, the SUP-P300 pressure transmitter has become a key device by virtue of its outstanding stability and accuracy. This article will provide an in-depth analysis of the successful application cases of this product in multiple large-scale petrochemical projects, showing how it helps customers achieve efficient process control and safe production.

1. Stringent Requirements for Pressure Transmitters in the Petrochemical Industry

The production environment in the petrochemical industry is usually accompanied by extreme conditions such as high temperature, high pressure, and corrosive media, which place extremely high demands on the performance of pressure transmitters. The SUP-P300 pressure transmitter adopts advanced sensor technology and durable 316L stainless steel material, and can withstand a pressure range of up to 1000bar and a temperature range of -40℃ to 125℃, ensuring stable measurement accuracy even under harsh working conditions.

In addition, this product has passed ATEX and IECEx explosion-proof certifications, complies with the safety standards of the petrochemical industry, and effectively avoids safety hazards caused by equipment failure. Its IP67 protection rating also ensures reliable operation in humid and dusty environments.

2. Application Case of SUP-P300 in a Refinery

In the catalytic cracking unit of a large refinery, the SUP-P300 pressure transmitter was used to monitor pressure changes inside the reactor. The operating pressure of this unit is as high as 30bar, the temperature exceeds 500℃, and the medium contains a large amount of catalyst particles. Traditional pressure transmitters are prone to measurement drift or even damage in such an environment.

With its unique diaphragm isolation technology and self-cleaning function, the SUP-P300 effectively prevents the accumulation and blockage of catalyst particles. Within one year after installation, its measurement error remained within ±0.1%FS, far exceeding the industry requirement of ±0.5%FS. This not only improved production efficiency, but also reduced raw material waste caused by measurement errors, saving the customer more than 2 million yuan in operating costs each year.

3. Outstanding Performance in an Ethylene Cracking Unit

Ethylene is an important basic raw material in petrochemicals, and pressure control in its production process is of vital importance. A petrochemical enterprise adopted the SUP-P300 pressure transmitter in its ethylene cracking unit with an annual output of 1 million tons, to monitor pressure fluctuations at the outlet of the cracking furnace.

This unit is characterized by rapid pressure changes and large fluctuations, requiring the transmitter to have an extremely fast response speed. The response time of the SUP-P300 is less than 10ms, enabling it to capture pressure changes in real time and provide accurate feedback signals to the DCS system. At the same time, its built-in temperature compensation function ensures measurement consistency under different ambient temperatures, avoiding control deviations caused by temperature changes.

After the project was implemented, the ethylene yield of the unit increased by 1.2%, generating additional annual benefits of more than 15 million yuan. The customer highly praised the stability and reliability of the SUP-P300 and plans to promote its use in other units.

4. Safety Protection Role at an LNG Receiving Terminal

The storage and transportation of liquefied natural gas (LNG) require strict safety control. A coastal LNG receiving terminal installed the SUP-P300 pressure transmitter on its high-pressure transfer pump to monitor the pump outlet pressure.

During LNG transportation, excessively high pressure may cause pipeline rupture, while excessively low pressure will affect the normal use of downstream users. The high-accuracy measurement and fast response characteristics of the SUP-P300, combined with the safety interlock system, can trigger protective actions in time when pressure is abnormal, thereby preventing accidents.

It is worth mentioning that this product can still maintain stable operation in an ultra-low-temperature environment of -162℃, and its special low-temperature sealing design effectively prevents LNG leakage. In the three years of operation of the receiving terminal, there has never been a shutdown caused by pressure measurement problems, fully proving the reliability of the SUP-P300 in extreme environments.

5. Product Advantages and Technical Features

Through the analysis of multiple application cases, we can summarize the core advantages of the SUP-P300 pressure transmitter:

• High-accuracy measurement: ±0.1%FS accuracy meets the most stringent process requirements
• Wide temperature range operation: -40℃ to 125℃ standard range, with higher specifications customizable
• Fast response: <10ms response time ensures real-time control
• Robust and durable: 316L stainless steel material, IP67 protection rating
• Safety certification: Passed ATEX, IECEx and other explosion-proof certifications
• Intelligent diagnostics: Built-in self-check function for predictive maintenance

These features make the SUP-P300 an ideal choice for pressure measurement in the petrochemical industry, especially suitable for key process links such as catalytic cracking, ethylene production, and LNG processing.
