    Abstract: A rotating drum in an oven is sealed against hot gas and air transfer. An annular outer seal holder has an L shaped cross section. A first end of the holder is connected to the oven. A second end is a radial flange. A backing plate has first and second sections. The first section has an inward extending guide. The second section has an inner diameter larger than an inner diameter of the guide portion. Bolts hold the backing plate and the seal retainer segments assembled on the flange. A cylindrical space between the radially guide portion of the backing plate and the seal retainer segments receives radially outwardly extending holder plates of segmental inner sealing elements. Partially cylindrical plates welded to the holder plates engage a drum wear plate. Leaf springs are connected to the seal retainer segments. Inner edges pressing the cylindrical plates radially inward.

    Abstract: The present invention is a decontamination plant for removing contaminates from contaminated material. The decontamination plant comprises an outer shell including a cavity therein. A drum formed of heat conductive material is rotatably mounted in the cavity defined by the outer shell so as to form an annular heating chamber between the drum and the outer shell. A plurality of heat sources are positioned to discharge heat into the annular heating chamber. The drum also has an inner surface defining a decontamination chamber. A tube is concentrically supported within the decontamination chamber formed in the drum. The tube has an inlet which is in communication with the annular heating chamber so as to receive flue gases therefrom. The outlet of the tube is positioned to exhaust gases from the drum. The drum is slightly inclined from a material receiving opening to a soil discharge end so as to cause the material which is being decontaminated to progress through the decontamination chamber as the drum rotates. While the material is passing through the decontamination chamber, the material is held in contact with the heating drum and the heated tube so as to heat the material via conduction.

    Abstract: A system for removing volatilizable organic contaminants from solid materials has a primary volatilizer and a secondary volatilizer positioned in series. A charging system continuously loads solid materials which have been blended to contain a predetermined concentration of contaminants into the primary volatilizer. A portion of the contaminants are volatilized in the primary volatilizer. The solid materials and the volatilized contaminants are transfered to the secondary volatilizer where the volatilized contaminants are burned to provide heat for help in volatilizing the remainder of the contaminants. The solid material which is now decontaminated is quenched. The gases are treated to convert the remaining volatilized contaminants to harmless gases and water vapor. Particulate material is removed from the gases. Nitrogen oxides and sulpher are also converted to harmless forms.

    Abstract: An asphalt recycling conveyor system has a substantially horizontal collecting trough for receiving returned, unused hot mix asphalt. Deflecting plates are provided at the back and ends of this trough, and spaced guard rails extend across it. Asphalt is moved in the trough by an auger having standard pitch to a hopper at one end of the trough. Asphalt lump breaking rods extend from the auger shaft above the hopper to prevent these lumps from bridging the hopper opening. An elevating trough may receive the asphalt from the collection trough hopper and carry it to a higher elevation. The elevating trough has an auger having one-half standard pitch and is turned at a faster speed than the collection trough auger. Heat trace lines are provided on the bottom of the troughs to prevent asphalt buildup.

    Abstract: A system for receiving and removing contaminants from soil, sand, etc. which has been contaminated by liquid contaminants. The contaminated material is heated in a rotating chamber sufficiently to volatilize the contaminants. The volatilized contaminents flow from one end of the chamber while the separated material is discharged from the other end as an uncontaminated material. Dust is removed from the volatilized contaminants and they are fed into a combustion chamber for conversion to harmless products of combustion.

    Abstract: A tar sand volatilizer system thermally removes petroleum crude oil from tar sands or shale oil. A series of heated augers or thermal screws are used to elevate material temperature gradually using conductive heat transfer. The thermal screws blades and auger case receive a heated fluid. The screws are driven by variable speed drive systems. The unit is sized for any throughput rate desired. Hot clean material discharges into a rotary cooler and re-hydrator unit. The exhaust gases are pulled through a high temperature filter collector for particulate removal. The particulate free petroleum vapor laden hot gas exits the filter house into a multi stage condenser system with water chillers where the vapor temperature is gradually cooled. A microwave upgrader system processes crude oil using catalyst injected microwave technology to produce a diesel like fuel oil in a continuous process stream.

    Abstract: A system for remediating soil containing contaminants. The system comprises a rotary volatilizer, a thermal dust conductor, a soil cooler, a separator and an afterburner. The rotary volatilizer includes a rotatable, counterflow volatilizer drum with a drying zone, a heating zone and a burn zone. The burn zone of the volatilizer has an outer shell and a stainless steel inner liner supported by spring brackets within the outer shell. A separator is provided to receive exhaust gases from the volatilizer and the soil cooler and to remove dust from the exhaust gases. Dust from the separator and hot soil from the volatilizer is introduced into the thermal dust conductor. Hot gases from the thermal dust conductor are returned to the volatilizer to preheat combustion air for the volatilizer and to incinerate contaminants in the returned gases. Soil is transferred from the thermal dust conductor to the soil cooler, where water injection cools the remediated soil and adds moisture to the soil. The cool remediated soil is conveyed from the soil cooler to a load out hopper.

    Abstract: A bag house air filtration system with minimal recirculation uses new inlet airflow patterns and cleaning processes. Inlet air enters the bag house. An input plenum changes the velocity profile. Dirty inlet air is split into two plenums, and then passed through guide vanes. A clean air plenum contains a series of individual compartments with a pre-set number of filter bags that are effectively cleaned during a single cleaning cycle. Each individual compartment has a door or louver mounted above the bag openings that is opened and closed during the cleaning cycle. An automatic control system continuously senses bag house pressure drop and activates the cycle when needed. The doors open and close in a pre-set pattern to drop the dust cakes from the bags and restore air flow to normal pressures. Closing a door mounted above the bags creates a reversal of pressure that removes the dust cake.
