Recycling Plant

THERMAL DESORPTION TREATMENT We offer Thermal Desorption Systems which can be used to process various materials. Specific design of the system depends not only on
your technological requirements but also environmental regulations
as well as local and company requirements.
Systems can process following materials:
• Hydrocarbon contaminated soil (following oil or fuel spillages, etc.);
• Drilling cuttings;
• Solid fraction after processing sludge on centrifuge;
• Sediments from oil and bunker oil tanks;
• Spend catalysts used in oil refineries, etc.

Thermal Desorption Treatment

INDIRECT FIRED THERMAL DESORPTION SYSTEM With proposed Thermal Desorption system, hydrocarbons are separated from the solids in the sludge. The treated solids/sludge may have zero residual hydrocarbons, resulting in an end product that can be disposed cost-effectively without harming environment. Technology overcomes many of the disadvantages associated with mechanical and other thermal technologies for desorption of hydrocarbons. Thermal process chamber is designed to have a large open capacity with low vapor exit velocity. By minimizing particulate in the vapor stream the recovered hydrocarbons are clean and can be used as fuel to heat the system or resold. Technology incorporates multiple heating zones along the length of the drum. This allows applying controlled heating at different temperatures within each zone of the drum. Typically, the first zone evaporates the water. The middle zones are used to remove hydrocarbons down to less than one percent, and the last zone is a polishing zone to take off heavy hydrocarbons and meet regulatory standards or customer's requirements for residual hydrocarbons.

Electrical Screw Thermal Desorption System

System uses an indirect thermal desorption process to remove and recycle hydrocarbons from contaminated solids. Discharged solids are safe for landfill disposal. Residual hydrocarbons can meet strictest customer requirements. The system uses a very low speed rotation and, as a result, reducing maintenance cost. Electrical heating elements contained within the hollow core of the screws are operated to heat the screws evenly at a controlled rate. Thermocouples are installed at the discharge end of the processor, which measures the material temperatures at the specified location. The equipment is designed airtight with nozzles for possible injection of an inert gas such as nitrogen to limit the oxygen content. The housing is totally insulated for minimal heat loss. An adequate number of vapor ports are installed in order to collect the off-gas emissions generated during system operation. Treatment of off-gas must remove particulates and contaminants using fabric filters and carbon adsorption procedures FULL SERVICE PROVIDED KMT offers comprehensive service, including:

We offer Thermal Drying Systems which can be used to process various type of materials. Proposed drying systems significantly reduce moisture content, thereby producing a desirable, and often sellable, end product.

 Thermal Drying of materials is a well-proven technology that reduces the volume and weight of solids. Dried products are more easily handled, stored and transported drastically reducing cost to customers. Drying materials makes it easier than ever to meet stringent environmental regulations and in many cases, can provide a sustainable source of energy to be used. ROTARY DRYER Rotary Dryers are reliable, durable, economical to run and efficient. The rotary dryer sturdy construction makes it a reliable solution for drying a wide range of materials. We offer two types of Rotary Drying Systems: ➢ DIRECT FIRED DRYING SYSTEM Mostly used for inorganic materials or materials with high moisture content. Such system can be designed in a parallel or counter-current flow configuration. In a parallel, or co-current, flow configuration, the hot gases and the product enter the dryer at the same end. The wet material comes into contact with the hot gas at its highest temperature, resulting in the rapid evaporation of surface moisture without overheating the product. In a counter-current configuration, the hot gas stream enters the kiln on the opposite end as the materials, and the dry product comes into contact with the gas at its lowest temperature.

INDIRECT FIRED DRYING SYSTEM Such systems are used when material has to be dried in controlled oxygenlean environment. Material is heated by several burners mounted trough isolated jacket. materials with low density and fine particles are mostly suited for this type of dryers. Proposed rotary dryers are equipped with specially designed flights to maximize heat transfer between the product and the hot gas stream. Rotary dryers are able to process and remove moisture from a variety of materials, from fertilizer to minerals to industrial waste. They are excellent for processing inorganic materials, such as aggregate, sand and foundry waste, at high process rates. Versatile and purpose-built to dry a wide variety of materials, our direct fired rotary dryers shower the material with a hot gas stream from end to end. HOLO-SCRU DRYER Holo-Scru drying system for your treatment plant is essential to maximizing cost efficiency and reducing environmental impact. The dryer system eliminates pathogens and reduces moisture content to 90% and volume to typically 20% or less

during biosolids drying. The HoloScru is a simple, easy to maintain dryer system with a small footprint. The fully automated system ensures exceptional product quality and safety. System effectively drying digested, undigested primary, waste activated sludge and mixes of these sludges (as is common for regional facilities). The design of the Holo-Scru includes features to continuously remove build-up from the heat transfer surfaces. The system also eliminates any large clumps from building and passing through the system via a series of cutters that break up and homogenize the particle size at each stage of the rotor. The heat energy for drying is indirect, created by thermal fluid circulated through the rotor, flitting and the outer jacket of the drying chamber in a closed loop. The drying process operates under a slight negative pressure in a sealed chamber.
