Supercritical fluid exchangers

Graham spherical Heliflow Heat Exchanger

Supercritical water oxidation (SCWO) is a cutting edge technology that has been developed for the treatment of hazardous waste solutions. This method uses high pressure, high temperature water at its supercritical state of 3200 psig and 705 degrees F. During this process, oxygen and the supercritical water are injected into the waste stream. The waste contaminants are oxidized, transforming them into carbon dioxide and other harmless substances.

This process is cost competitive and more environmentally friendly than traditional disposal methods, such as land fill or incineration.

Specially designed Heliflows with spherical casings are used to withstand the high operating pressures and temperatures required. These units are used to cool the reactor effluent, to generate steam, as a feed interchanger, and as sample coolers.
