The QBJ Thermal Oxidation Units are designed to continuously incinerate still effluents from glycol dehydrators and amine units. The QBJ TO design introduces excess air mixed with the heated still effluents so that combustion and destruction occur at the operational temperature of between 1300°F and 1500°F. Our designed is based upon a 2 second retention time in order to assure a continuously thermal destruction of the hydrocarbon effluents from TEG and Amine regenerator in order to meet current environmental requirements for BTEX destruction.
QBJ Thermal Oxidizers are normally equipped with:
- Still Effluent 3-way Diverter Shutdown Valves
- Inlet Effluent Flash Arrestor
- Inlet Liquid Knockout
- A TEG Stack / Still Column Stack Heat exchanger
- Quench (Excess) Air Blower with PLC actuated temperature / flow control
- 6” or 9” Pyroblock Ceramic Refractory Lined Combustion Chamber
- Forced Draft Burner System
- Burner Controls Compliant with the Latest NFPA Standards
- Combustion Chamber Temperature Control
- Stack High Temperature Shutdown
- Modular Constructed for Ease of Installation
- NEMA 4 Control Panel
The Still Column effluents enter the unit through kimray three-way valves mounted by the customer on the Still Column effluent lines. The effluents enter the bottom of the heater and exit at the top. The heater design prevents liquid carry over into main combustion chamber. The hot effluent vapors are then piped to the combustion chamber where incineration occurs. The incineration products are released to the atmosphere via a refractory lined stack. The stack gases are cooled by the addition of air from a blower mounted on the stack. This prevents the stack gases from exiting at the temperature that is potentially dangerous from a standpoint of accidental ignition of free hydrocarbon vapors at the site.
