Basics
- A Technology where Supercritical Conditions are used in a Water Rich Mixture to Oxidize (Often in a manner to Incineration ) It's Components
- It is mainly used for Wastewater Treatment , but also has applications in Thermal Hydrocarbon Cracking and Hazardous Waste Disposal
- When applied to the disposal of hazardous waste it has a high Destruction and Removal Efficiency
- Supercritical Water is a Non-Polar Solvent, so most minerals precipitate as salts
- This is actually one of the main issues with the technology, in Radially Heated / Non-Cooled + Laminar Flow Reactors, the sides get coated in precipitate, reducing heat transfer
- Also if not made with something very corrosion resistant such as Inconel etc the reactor can corrode and explode
- Also because of this oxygen and hydrocarbons diffuse very well
- This is actually one of the main issues with the technology, in Radially Heated / Non-Cooled + Laminar Flow Reactors, the sides get coated in precipitate, reducing heat transfer
