Abstract
Simple flow path with minimum turns for the vapor extraction flow paths can provide maximum air flow with minimal head loss, leading to higher efficiency in a thermal desorption process. Hot air vapor extraction arrangement can include large diameter vertical or horizontal trunk line or curved plate with continuous wire wrap well screens. The vapor extraction trunk can draw all vapors to the center of the soil box, which can reduce the treatment time by substantially removing condensation zone. The interior of the vapor extraction well screen and trunk can include porous material, which can reduce dust within the vapor stream, eliminate potential short circuiting in the event of a screen rupture and reduce potential explosion hazards.
