Torch column, the core equipment of the torch system, is used to safely discharge and burn combustible waste gases (such as VOCs, combustible tail) in industries such as petrochemicals and chemical industry.
1. Safe emission: Receive the waste gas treated by the upstream split tank and water seal tank, and through high-altitude emission combustion, combustible/toxic gases (such as hydrocarbons, H2S) into CO2, H2O (part of which contains SO2, etc., which supporting desulphurization), to avoid direct emission polluting the environment or causing explosions. 2. Combustion enhancement: Airflow distribution structures (such as guide, stable combustion rings) can be set inside the cylinder to fully mix the waste gas with air, ensuring complete combustion (reducing black smoke and improving purification efficiency); the top head integrates high-energy igniter and constant flame lamp to achieve automatic ignition (quickly ignite during emergency emission).
1. Shell:
1. Material: mostly carbon steel / stainless steel (stainless steel or lining is used when there is a high demand corrosion resistance), thickness needs to be calculated for wind load, seismic load (especially for high torch, the height can reach 80-120 meters). . Lining: refractory castable / ceramic fiber is set in the high temperature section (flame zone) to prevent the shell from overheating and deformation; anticrosive treatment is done in the low temperature section (to deal with acid rain, waste gas condensation corrosion).
2. Auxiliary system:
1. Pilot light burning 24 hours a day (or pulse ignition), to ensure instant ignition in case of emergency discharge; 2. Ignition system: electric ignition / gas ignition, with DCS (automatic ignition trigger when the pressure is too high); 3. Purging system: use nitrogen for purging before shutdown and maintenance, to replace the internal flable gas and prevent explosion.
1. Waste gas characteristics: 1. High concentration of hydrocarbons (e.g., from refinery) → Large diameter, high torch ( avoid backfire); 2. Low concentration of VOCs (e.g., from paint exhaust) → Integrated catalytic combustion, catalyst parameters need to be matched.2. Geographical environment: 1. Coastal / high humidity → Strengthen anti-corrosion (316L stainless steel); 2. High altitude Adjust ignition system (atmospheric pressure affects flame stability).
1. Liquid-gas separator: first separate the condensate in the waste gas (to prevent liquid seal, fire rain), and then purify the gas the flare stack; 2. Water seal tank: control the back pressure through the water seal height, which allows normal exhaust and prevents flashback (flame backflow into the pipeline); 3. Gas-liquid separator: further liquid and solid removal under complex conditions (such as multiple waste gas mixed discharge), and protect the flare head
Petrochemicals/refining: emergency venting from atmospheric/vacuum distillation unit, catalytic cracking unit, discharge of hydrocarbons, H, etc.;
Coal chemical industry: coal gasification, coke oven gas venting from coke plants;
Environmental control: waste gas combustion fromTO/RCO system for VOCs control (some processes integrate the flare stack with the combustion chamber).
