Sharq, Kuwait, KW
Remediation,
Kuwait has been letting large thermal remediation jobs for decades. The plant shown in the photo is an indirect fired Tarmac soil remediation plant that ran over 300,000 tons. In Tarmac’s indirect fired plants, the hydrocarbon is first brought up to a high temperature as a fume leaving the soils treated to low hydrocarbon levels. The fume is then cooled and condensed into a thick liquid to be recycled.
Indirect fired plants are typically used when the project requires the gas flow within the dryer (super heated steam and hydrocarbons) to be separate from the dryer’s heat source. There can be two common reasons for this:
- Specific contaminants (i.e. chlorinated compounds) are required to be out of direct contact with the dryer flame.
- The hydrocarbon content is too high within the soil (such as 300,000 PPM oil based drill cutting). TI219
