Customizable Flare Stack for Gas Storage Facilities

Product Description

 

Product Introduction

The elevated flare is an open-type industrial waste gas combustion device installed on a high-altitude tower. It is mainly used in petroleum, petrochemical, natural gas, coal chemical, LNG and other industries to treat flammable and toxic waste gas from startup/shutdown, emergency blowdown and continuous venting. It realizes harmless disposal of waste gas through high-altitude combustion, featuring super-large flow discharge capacity, stable and reliable operation, and wide application range. It is a key environmental protection equipment for the safe production of industrial plants.

• Super-large Discharge Capacity: Withstands instantaneous super-large flow waste gas discharge, suitable for safe emission during plant emergency shutdown and accident conditions
• High-altitude Safety Isolation: Flame is far away from ground equipment and personnel, with minimal impact of heat radiation and noise on the plant, no potential safety hazards
• Simple & Reliable Structure: Open design, no complex combustion chamber structure, low failure rate and extremely low operation and maintenance cost

 

• Wide Working Condition Adaptability: Can treat various complex component waste gases such as low-pressure, high-pressure, sulfur-containing and dust-containing gases, with strong adaptability
• Pilot Burner Guarantee: 24-hour pilot burner + high-energy ignition system, ensuring 100% successful ignition under any working conditions
• Environmental Compliance: Combustion efficiency > 99%, equipped with steam/air assisted combustion system to realize smokeless combustion, meeting environmental protection standards
high automation:Supports DCS/PLC remote monitoring, high automation, safe and controllable operation.

 

Working Principle

 

 

The core of the elevated flare is controlled high-altitude combustion technology. Through the four-step process of "gas intake control → precise ignition → high-altitude combustion → safe emission", it realizes harmless treatment of industrial waste gases. The specific process is as follows
1. Gas Intake Control: Waste gas enters the flare system through pipe network, flame arrester and separator drum, automatically adjusts intake pressure and flow rate, separates condensate and impurities, avoiding flashback and liquid carry-over risks
2. Precise Ignition: The system automatically triggers the high-energy ignition device according to waste gas flow and concentration, with the pilot burner continuously burning to ensure instant ignition when waste gas enters

3. High-altitude Combustion: Waste gas is fully burned in the high-altitude flare tip, equipped with steam/air assisted combustion system to realize smokeless combustion. Combustible substances are converted into CO2and H2O, and toxic substances are decomposed simultaneously
4. Safe Emission: The burned flue gas diffuses rapidly at high altitude, with minimal impact of heat radiation and noise on the ground. The whole process is monitored in real time by DCS system to ensure safe and stable operation

 
 

Application Scenarios

• Refining & Petrochemical Plants: Treatment of emergency blowdown gas and continuous emission gas from CDU, FCC, ethylene and other units
• Oil & Gas Fields & Long-distance Pipelines: Combustion of oilfield associated gas, pipeline pigging gas and emergency vented natural gas
• LNG Terminals & Storage Stations: Safe combustion of BOG and tank overpressure vent gas

• Coal Chemical & Coking Plants: Treatment of combustible waste gases such as syngas, coke oven gas and purge gas
• Large Chemical Parks: Centralized flare in the park, treating waste gas discharge from multiple units
• Offshore Platforms & FPSOs: Waste gas combustion for offshore oil and gas production platforms, ensuring safe offshore operation
