The

Thermal Desorber offers the following advantages:

• Very low cost

• Unique construction with proprietary internals, process seals, and air polution control system allows manufacturing cost to be drastically reduced.

• Very low weight

• The typical direct fired rotary kiln or fixed hearth incinerator uses large quantities of high density hard refractory. The PTI thermal extractor requires none, resulting in tremendous weight and cost savings.

• Minimum site preparation

• Due to modular construction and trailer mounting site preparation can be a simple as leveling the required area.

• Very low utilities consumption

• During normal operation with typical plant waste, excess heat will be generated by the Thermal Oxidizer. Depending on process requirements, some or all of this heat is ducted through the plenum of the thermal desorber to heat the incoming feed. Therefore, the Thermal Oxidizer burner will normally consume no fuel. The normal utility requirements will consist of only the power required to drive the fans, kiln drive, and loader drive.

• Less than 4 hour start-up and 2 hour shut-downs

• The ceramic fiber refractory used in both the kiln firebox and the thermal oxidizer is insensitive to thermal shock. The typical direct fired rotary kiln requires two or three days to reach operating temperature

• Wet or dry low maintenance ash removal system

• The Pressnall Technology AWS wet ash removal system uses water to provide a positive seal for the solids discharge chute of the kiln. It has no bearings or articulated joints submerged the liquid. Therefore, wear and the resulting maintenance are greatly reduced.

• The Pressnall Technology ADS dry ash removal system relies on the material being conveyed to seal the solids discharge chute of the kiln. The bearings are externally mounted and protected from the heat. Both water cooled and air cooled versions are available, depending on the specific requirements of the process.

• Low maintenance high efficiency scrubbing system

• By cleaning the gas after it exits the Thermal Desorber and before it enters the Thermal Oxidizer, a much smaller volume of gas requires treatment. This results a much smaller scrubber, reducing the capital and operating costs. The Thermal Oxidizer burns only cleaned gases therefore its exhaust is clean. In addition, the Pressnall Technology scrubber system uses less power

• Hydrocarbon Recovery

• When treating oil contaminated soil, the heavy ends of the oil are recovered in the scrubber. These have value as fuel or chemical feedstock.
