Elevated flare

System Overview  

The elevated flare system is a critical safety emission device used in petrochemical and natural gas processing industries. It is designed for the emergency or continuous combustion of combustible waste gases and toxic gases, achieving harmless treatment through high-temperature oxidation. The system features high-efficiency combustion, safety, and stability.  

Core Components  

- Flare Tip: Multi-stage combustion structure integrated with steam smoke suppression/air-assisted combustion technology to ensure complete combustion.  

- Flare Stack: High-temperature-resistant stainless steel material, with a height of 30-150 meters, ensuring safe gas dispersion.  

- Ignition System: High-altitude automatic ignition device equipped with a pilot flame and flame detector.  

- Control System: PLC/DCS integration for real-time monitoring of pressure, flow, and flame status, supporting interlock protection.  

- Support Structure: Self-supporting tower or guyed mast, made of carbon steel/stainless steel, with earthquake and wind-resistant design.  

Technical Advantages  

- Efficient Treatment: Single tower processing capacity of 500-500,000 Nm³/h, with a combustion efficiency of ≥98%.  

- Safe and Reliable: Molecular seal to prevent flashback, nitrogen purge system + thermal radiation monitoring to eliminate explosion risks.  

- Environmental Compliance: Combustion products meet emission standards.  

- Flexible Adaptation: Configurable with steam injection, gas-liquid separation, silencers, and other modules to adapt to complex working conditions.  

Application Scenarios  

- Petrochemical Industry: Emergency vent gas treatment in refineries and chemical plants.  

- Natural Gas Processing: Combustion of associated gas in LNG receiving terminals and gas field extraction.  

- Coal Chemical/Pharmaceutical Industries: Harmless treatment of process tail gas and emergency emissions.  

The elevated flare system, with its high reliability, strong environmental adaptability, and intelligent control, serves as a core safeguard for industrial safety and environmental management. It helps enterprises achieve risk control and compliant emissions.
