Supercritical Water Oxidation

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
• 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
