What to understand about Thermal Desorption?
Thermal Desorption is one of the physical separation procedures, contaminated soils are simply heated to volatilize organic and water contaminants. A carrier gas or even vacuum system transports volatilized water as well as organics to the gas treatment system. There are usually three methods of thermal desorption: · Indirect heated An outwardly fired rotary dryer volatilizes the water as well as organics from a contaminated media into the inert carrier gas stream; steam can also be utilized as an indirect heating method. · Indirect fired The straight direct-fired rotary dryer heats the air stream that is in contact with the contaminated soil. · Direct fired Fire gets applied directly upon the surface of contaminated media. Thermal desorption procedures can be separated into two groups: Low temperature thermal desorption (LT...
