How does thermal desorption work?

How the MCS works
Volume reduction: Sludge or contaminated effluent solids are filter pressed or centrifuged to produce a cake.
Loading: Trays containing the waste cake are loaded into the MCS, and a hood seals the trays inside the unit.
Thermal desorption: Infrared energy heats the base of the trays. A vacuum reduces the boiling points of any volatile chemicals and draws heating-system exhaust gas through the cake matrix to displace air and create a non-flammable atmosphere. The volatile chemicals quickly evaporate and are stripped from the thermal unit.
Off-gas treatment: The volatile compounds are fed into an emissions control unit and are recovered as liquids through the off-gas treatment system.
Quick and efficient
Unlike less-sophisticated hot-box systems, which can take days to complete a cycle, each MCS treatment cycle takes 2–3 hours, with 5–10 minutes being required to change out the trays. Multiple trays and thermal units give the production rates of continuous-feed processes.
Bespoke systems
The unit’s modular design means that it is flexible and can be modified to treat different throughputs and types of waste. Each system is built to meet individual project and customer requirements.
