A thermal oxidiser was designed and installed by ABM to mitigate the emissions produced by the bitumen storage facility.
The thermal oxidiser is vertically fitted with an integral ABM burner. The upper chamber and stack are constructed from carbon steel with stack bonded 1,400oC lining. The shell is coated with an insulating paint to minimise heat loss. The lower chamber is constructed from carbon steel with 1,650oC hard refractory lining with an insulating refractory backup.
The thermal oxidiser is fired by natural gas and the gas train includes isolation valves, filter, regulator, transmitting flow meter, pressure switches and double block and vent pneumatic valves. Key benefits include:
- The design destroys 99.9% of VOCs within the vapour flow
- Equipment shutdown can be for up to 6 months, but the thermal oxidiser can also brought to full operational temperature within 15 minutes
- Minimum operating temperature is 825 deg C and the equipment operates with a sound pressure level of 84 dB
- Equipment is very reliable and emissions output is accurately measured
