Gas gathering station flare

System Overview  

The vent flare system is a critical safety device in the petrochemical and natural gas processing industries, designed for the emergency or planned discharge and combustion of combustible gases. It achieves harmless treatment through high-temperature oxidation, featuring high-efficiency combustion, safety, and stability, while meeting stringent standards.  

Core Components  

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

- Flare Stack: High-temperature-resistant stainless steel material, with a height of 10-150 meters, ensuring safe gas dispersion.  

- Ignition System: 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 to eliminate explosion risks.  

- Environmental Compliance: Combustion products meet emission standards.  

- Flexible Adaptation: Configurable with steam injection, gas-liquid separators, 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 vent 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.
