The hydrogen production process is crucial, and the oxygen in hydrogen analyzer, hydrogen in oxygen analyzer, and dew point analyzer work together to safeguard system safety and hydrogen quality. This article deeply analyzes the key roles and application scenarios of the three core instruments in the hydrogen production process.
What are the roles of hydrogen in oxygen, hydrogen in oxygen analyzer, and dew point analyzer?
In the context of the increasing demand for clean energy today, hydrogen production technology is receiving more and more attention. In the process of hydrogen production, Hongruitao Technology has three important instruments - HT-FX100-H2 oxygen analyzer, HT-FX100-O2 hydrogen analyzer, and HT-FD500 explosion-proof dew point analyzer, each of which plays a key role in ensuring the safety and efficiency of the hydrogen production process. Today, let's delve into the specific functions of these three instruments in hydrogen production.
During the hydrogen production process, the HT-FX100-H2 oxygen analyzer, HT-FX100-O2 hydrogen analyzer, and HT-FD500 explosion-proof dew point analyzer each perform their respective duties, ensuring the stable operation of the hydrogen production system from three key dimensions: safety monitoring, purity assurance, and humidity control. Their specific functions are as follows:
2. Oxygen hydrogen analyzer - prevention and control of explosion risk on the oxygen side
In the process of hydrogen production (such as electrolysis of water), hydrogen and oxygen are usually generated in different gas paths, but cross mixing may occur due to equipment leaks, membrane damage, and other issues. When hydrogen gas is mixed into oxygen, if the concentration of hydrogen gas reaches the explosive limit of 4%~75%, it may cause an explosion when exposed to a fire source. The core function of HT-FX100-H2 oxygen hydrogen analyzer is to monitor the hydrogen content in oxygen products in real time. When the hydrogen concentration approaches the safety threshold (usually set at 1/4~1/5 of the explosion limit, such as 1%~2%), an alarm is triggered and the system is linked to shut down to avoid explosion accidents. -Commonly used at key nodes such as oxygen outlets and oxygen storage tanks in electrolytic cells, it is the core equipment that ensures the safety of the 'oxygen side'.
3. Hydrogen oxygen analyzer - ensuring hydrogen purity and safety
As a product, the purity of hydrogen directly affects its application value (for example, fuel cells require a purity of over 99.97%, and chemical synthesis is more sensitive to impurities), and there is also a risk of explosion when oxygen is mixed into hydrogen (oxygen concentration of 4%~94% will trigger the explosion limit). The core function of HT-FX100-O2 hydrogen oxygen analyzer is to detect the oxygen content in hydrogen products online, ensuring that the purity of hydrogen meets downstream standards (such as the national standard GB/T 37244-2018, which has clear limits on the oxygen content of different grades of hydrogen). -When the oxygen concentration exceeds the standard, timely warning should be given to avoid unqualified hydrogen entering the storage or use process, and to prevent the risk of hydrogen side explosion caused by excessive oxygen content. -Widely used in key processes such as hydrogen drying, tank inlet, and before filling, it is a dual guarantee of purity and safety on the 'hydrogen side'.
4. Dew point meter - controls hydrogen humidity to avoid equipment damage and performance degradation
The moisture (humidity) in hydrogen can cause multiple hazards to the hydrogen production system and downstream equipment: it may freeze and block pipelines in low-temperature environments; -Corrosive metal equipment (such as compressors, storage tanks); -Reduce fuel cell efficiency (moisture can affect proton conduction).
The core function of HT-FD500 explosion-proof dew point transmitter is to indirectly reflect the absolute humidity in hydrogen by measuring the dew point temperature of hydrogen (corresponding to the moisture content at a specific pressure) (such as a dew point of -60 ℃ corresponding to a moisture content of about 10ppm). -Ensure that the humidity of hydrogen meets the process requirements (such as controlling the dew point of hydrogen after electrolysis of water to below -40 ℃, and using hydrogen for fuel cells to below -60 ℃). -Commonly used in drying machine outlets, hydrogen storage tanks, and other processes to guide the operation of drying equipment and avoid equipment damage or performance loss caused by excessive moisture.
5. Collaboration of Three Major Instruments - Hydrogen Production Safety and Quality Closed Loop
Although the functions of the three are different, they together form a 'safety purity quality' closed loop in the hydrogen production process: - the hydrogen in oxygen analyzer and the hydrogen in oxygen analyzer focus on explosion risk prevention and control, respectively guarding the gas safety of the oxygen side and hydrogen side; -The dew point meter focuses on hydrogen quality control to ensure the stability of downstream applications. Under the trend of large-scale hydrogen production and high purity demand, these three types of instruments are key detection equipment.
