As the proposed technology uses less amount of fossil fuel, it is more economical from an energy standpoint, andgiven that the ambient temperature is suitable for oil degradation, according to the characteristics of the injection of
microwaves into the soil by the high temperature heating element, the degradation takes place at a faster rate than
that of thermal desorption using hot blasts. More specifically, the aim was to develop a new commercial technology
for removing oil pollution based on heat treatment that can be used on-site in the field, which meets the following
criteria: volatile contaminants are degraded at lower ambient temperatures than that required in the thermal
desorption process; low-cost and highly efficient with min. treatment capacity of 3 ton/day using the characteristic of
rapidly rising temperatures. For types of oils that include lubricating oil or cutting oil, treatment resulted in TPH
concentration that was below the threshold required for restoration of oil contaminated soils, except when treatment
was done at 8kW and 500℃. On the other hand, for soils contaminated with the ordinary type of oil, treatment
resulted in TPH concentration that was below the same threshold even at 8kW and 500℃ in less than 20 minutes.
The rate of oil removal according to classification based on the particle diameter was high at 80%~98%. It was also
shown that the treatment rates didn’t differ much according to the particle diameter. To purify the exhaust gas that
was generated from the treatment of oil contaminated soil, a gas purification device was manufactured to analyze the
exhaust gas. The results showed that dioxins and VOCs released into the atmosphere were below the allowable levels.
As such, it is deemed that there won’t be secondary pollution from the purification of oil contaminated soils.
