Heated Overland Thermal Treatment Pad (‘Hottpad’) System at the Karratha Liquid Waste Treatment Plant and Waste Transfer Station

Project
Proposal description: 

The proposal is for the installation and operation of a Heated Overland Thermal Treatment (‘Hottpad’) system at the Karratha liquid waste treatment plant and waste transfer station located approximately 6 kilometres south-west of Karratha. 

The Hottpad is intended to treat hydrocarbon-impacted ‘sludge’ from oil and gas operations in the region, that are currently transported interstate for thermal treatment. The proposal has a project life of 10 years and involves a self-sustaining smouldering combustion process to thermally degrade hydrocarbon contaminants. 

The system comprises: 

  • Two containerised Hottpad units 

  • An exhaust management system, including a mercury recovery unit, odour control and stack 

  • Continuous emissions monitoring system
