(C₂H₄) High-Precision Laser Gas Analyzer

1. Process Monitoring Scenarios in Petrochemical Production
Petroleum Refining: In the core equipment for ethylene production via naphtha cracking, including cracking furnaces, quench towers and fractionation towers, real-time monitoring of ethylene concentration is conducted to accurately control the cracking reaction process and separation efficiency. It provides data support for adjusting process parameters such as cracking temperature and pressure, improving the yield and purity of ethylene products. Meanwhile, it monitors potential leakage points such as device pipelines and valves, issues timely warnings against ethylene leakage risks, and avoids safety accidents caused by flammable gas accumulation.
Olefin Deep Processing: In production workshops for polymers like polyethylene and polyvinyl chloride, ethylene concentration at the feed and discharge ports of reactors is monitored to ensure precise raw material ratio for polymerization reactions and guarantee the stability of product quality. Continuous ethylene concentration monitoring is carried out in confined spaces of the workshops to prevent personnel poisoning or explosion hazards caused by gas leakage.
Chemical Storage and Transportation: Fixed deployment or mounting on inspection robots is adopted in ethylene storage tank areas, loading/unloading stations and along conveying pipelines to achieve 24/7 uninterrupted monitoring. It enables real-time tracking of tank sealing conditions and pipeline leakage status, ensuring the safety and controllability of ethylene storage and transportation links.

2. Monitoring Scenarios in Fruit and Vegetable Preservation and Food Processing
Controlled Atmosphere Storage of Fruits and Vegetables: Ethylene concentration in storage environments such as controlled atmosphere cold storage and fresh-keeping warehouses is monitored. As a "ripening hormone" that accelerates the ripening and senescence of fruits and vegetables, excessive ethylene accumulation will speed up their decay and deterioration. The analyzer can feed back concentration data in real time, and link with ventilation systems or ethylene removal equipment to control the concentration within an optimal range, extending the fresh-keeping period of fruits and vegetables and reducing storage losses.
Food Processing Workshops: In production processes such as wine brewing and fruit and vegetable juice processing, ethylene concentration generated during fermentation is monitored to assist in judging the fermentation progress, ensuring the stability of food processing technology and the consistency of product quality.

3. Environmental Monitoring and Emergency Response Scenarios
Unorganized Emission Monitoring in Petrochemical Parks: Grid deployment of analyzers or mobile inspections via robots is implemented in areas such as plant boundaries, sewage treatment stations and waste residue yards of petrochemical enterprises to accurately identify ethylene unorganized emission sources, providing data support for enterprise emission reduction management and environmental compliance.
Emergency Monitoring of Sudden Leakage: At emergency sites such as ethylene storage tank leakage and transportation pipeline rupture, robots equipped with the device are rapidly deployed to conduct real-time monitoring of ethylene concentration in the leakage area. It delineates safe protection zones for emergency rescuers and guides emergency disposal work such as leak plugging and personnel evacuation.
Industrial Waste Gas Emission Monitoring: At waste gas outlets of petrochemical enterprises, the analyzer is connected to environmental supervision platforms to upload ethylene emission data in real time, ensuring that the emission concentration complies with national standards and helping enterprises achieve environmental emission reduction targets.

4. Scientific Research Experiments and Special Field Scenarios
Laboratories in Universities and Research Institutes: Applied in research fields such as plant physiology and atmospheric chemistry. For example, it monitors the ethylene content released or absorbed during plant photosynthesis and respiration, analyzing the regulatory mechanism of ethylene on plant growth and development. In atmospheric pollution simulation experiments, it accurately detects the reaction process between ethylene and other pollutants, providing high-precision data for the research on the formation mechanism of photochemical smog.
Agricultural Scientific Research Applications: In scenarios such as breeding test fields and greenhouses, the ethylene release rules of different crop varieties during their growth cycles are monitored, studying the effects of ethylene on crop flowering, fruiting and senescence, and supporting the breeding of crop varieties with high fresh-keeping performance and good storability.
Auxiliary Monitoring in Semiconductor Manufacturing: In some semiconductor material synthesis processes, ethylene concentration in the reaction environment is monitored to ensure that the raw material purity meets the process requirements and guarantee the yield of semiconductor chip production.
