Applications of Thermally Enhanced Vapor Extraction Technology (TEVET) for Contaminated Land Management in Asia

by Paul Kau (WSP)

10:30 am



Conventional remedial technologies such as soil washing, chemical oxidation and biopiling have been commonly used as “default technologies” for treating petroleum hydrocarbon impacted soils throughout Asia. While these technologies are mature and well-understood, the ever-growing urbanisation in Asia is exposing some inherent disadvantages of these systems and encouraging the exploration of other remedial technologies, such as the thermally enhanced vapor extraction technology (TEVET), a small-scale low temperature thermal desorption technology. In this presentation, a brief overview of these technologies will be made, together with several case studies of successful TEVET projects in Asia.
