A large petrochemical enterprise has an advanced hydrocracking unit, and its hydrogenation reactor uses hydrogen to treat heavy oil under high temperature, high pressure, and catalyst conditions, converting it into more valuable light oil products such as gasoline, diesel, etc. In this process, the purity of hydrogen is crucial. Even trace amounts of oxygen mixed into the hydrogen and entering the reaction vessel may undergo violent reactions with the hydrogen in a high-temperature and high-pressure environment. This not only damages expensive catalysts, reduces their activity, and leads to a decrease in reaction efficiency, but may also cause safety accidents, such as explosions and other dangerous situations.

Selection considerations for hydrogen oxygen analyzer：

Measurement accuracy and rangeGiven the strict requirements for hydrogen purity in the process, it is necessary to be able to accurately detect extremely low levels of oxygen. The selected hydrogen oxygen analyzer has a measurement accuracy of ± 0.5 ppm and a measurement range of 0-10 ppm, ensuring that extremely small changes in oxygen in hydrogen can be accurately captured, so as to take timely measures to ensure the safe and efficient reaction inside the reactor.

stability and reliabilityDue to the continuous and uninterrupted operation of the hydrocracking unit, with only a short maintenance period throughout the year, it is required that the analyzer must have high stability and be able to operate reliably for a long time in harsh industrial environments such as high temperature, high humidity, and the presence of certain corrosive gases. The company has chosen aChengdu Hongrui Tao YouHT-FX100 Explosion proof Hydrogen Oxygen AnalyzerThe HT-SY50-EX explosion-proof gas analysis system integrated with pre-processing sampling,The analyzer adopts high-quality electrochemical sensors and has multiple redundant designs. Its internal temperature and pressure compensation mechanism can effectively cope with the complex working conditions around the reactor, ensuring the accuracy and stability of measurement data. In actual operation, it can work continuously and stably for several months without manual intervention or calibration.

Function and usability：HT-FX100 Hydrogen Oxygen AnalyzerEquipped with an intuitive LCD screen, it can display real-time and clear oxygen concentration values as well as historical data records, making it convenient for operators to view at any time. At the same time, it also has remote monitoring function, which is connected to the enterprise's central control system, allowing technicians to real-time grasp the oxygen content in hydrogen gas in the central control room. In addition, the over threshold alarm function is set to immediately notify on-site and remote staff through sound and light alarms and sending alarm signals to the central control system once the oxygen content approaches the dangerous value (such as exceeding 2 ppm), in order to prevent dangerous situations from occurring.

after-sales serviceConsidering that equipment failure may have a huge impact on the entire production process, the company focuses on examining the manufacturer's after-sales service capabilities. The final selectionChengdu Hongruitao TechnologyWe have a professional after-sales maintenance team that can provide 24-hour response service and regularly conduct follow-up and maintenance on the equipment to ensure that it is always in the best operating condition. At the same time, Chengdu Hongruitao can also provide sufficient spare parts to ensure that they can be quickly deployed when replacement parts are needed, minimizing equipment downtime.

Usage effect：
Self install thisHT-SY50-EX Explosion proof Gas Analysis SystemLater, in the daily operation of the hydrogenation reactor, it timely and accurately detected the abnormal fluctuation of oxygen content in hydrogen for many times by virtue of high-precision measurement and stable and reliable performance, enabling operators to adjust the hydrogen supply system in advance, check possible oxygen mixing sources, effectively protect the activity of the catalyst, and ensure the efficient and stable hydrocracking reaction. At the same time, the improved alarm and remote monitoring functions enhance the safety of the entire production process, avoiding safety accidents caused by excessive oxygen, and playing an important role in the smooth production and economic benefits of the enterprise.
