The High Temperature Treatment Unit (HTTU) by econ industries is an advanced thermal processing solution specifically designed for the safe and efficient treatment of hazardous waste such as spent catalysts, activated carbon, and other kind of waste containing mercury sulphide (HgS) and mercury chloride (HgCl2). Primarily serving industries such as oil and gas and off-gas treatment systems, the HTTU ensures comprehensive mercury removal while enabling the recycling and reuse of valuable resources.
Operating at material temperatures between 700°C and 800°C, the HTTU utilizes high-temperature treatment to effectively break down mercury sulphide (HgS), recovering elemental mercury through a controlled condensation process. During this thermal transformation, sulphur compounds are oxidized to sulphur dioxide (SO₂), which is subsequently captured and neutralized in an alkaline scrubber system. This approach not only removes hazardous contaminants, but also ensures that the treated activated carbon or catalyst is mercury-free, allowing safe reactivation or recycling in future applications.
Flexible Integration and Operational Modes
The HTTU is designed with operational flexibility in mind, allowing it to function either as a standalone unit or if required, in combination with the VacuDry® process:
- Combined Operation with VacuDry®: When integrated with the VacuDry® process, the treated solid is discharged into a hermetically sealed bunker, which safely transfers the material to the HTTU for further thermal treatment, if required. Alternatively, the material can be directed to a cooling screw conveyor for safe handling.
- Standalone Operation: In standalone mode, the HTTU can directly process catalysts or activated carbon containing mercury compounds, streamlining the treatment process and reducing overall processing time. This setup is ideal for dedicated waste streams requiring specialized high-temperature treatment.
