Large-scale pyrolysis plant

This pyrolysis plants efficiently treats 8-10 tph of soil contaminated with mercury, organics (polycyclic hydrocarbons, mineral oil hydrocarbons, acid resins, chlorinated compounds (dioxins, furans, PCB), and other poisonous or dangerous like pesticides, cyanides, explosives. Actual plant capacity depends on type of contamination.

After the inital screeening to separate big stones and other bulky objects, the contaminated soil is dryed  and then sent to the pyrolysis kiln.  Clean soil is unloaded from the pyrolysis kiln while gases, containing contaminants, are further terated in the gas cleaning system comprised of both dry cleaning and wet scrubber units. 

When required this pyrolysis plant also performs regeneration of a spent activated carbon


MSW pyrolysis plant

Municipal, industrial and bulky waste is delivered by waste collecting vehicles and discharged into the coarse waste storage bin. The waste is then picked up by a crane, discharged onto two alternative operated rotor cutters and then delivered into the fine storage bin. Some sewage sludge is also delivered there.

Crane mixes waste and sewagesludge in order to obtain a homogeneous mixture.The crane transfers the mixed waste into the feeding hoppers of the charging devices of the two rotary kilns.The conveyors transport the waste from the hoppers to the feeding chute, consisting of a gas-tight slide gate valve (prevents air access to the kilns) and a chute. A feeding screw arranged downstream the feeding chute conveys the waste into the pyrolysis kiln.

The pyrolysis of the waste materials takes place into two indirect heated rotary kilns. The kilns have heated lengths of about 20 meters and an inner diameter of about 2.2 meters. Each kiln has a capacity of 3 tons per hour. Waste is thermally degraded using an indirect external source of heat at ~500 C in the absence of free oxygen supply. Solid residuals of the pyrolysis process are removed via a wet discharger. The pyrolysis gas is sealed from the atmosphere by the water level in the discharger. Metals are extracted by an overhead magnetic separator discharged into a container for recycling.

The exhaust gas from the boiler is thoroughly cleaned in the emission control subsystem in order to achieve the full compliance with the emissions limits. The volatile portion of the feedstock produces syngas, which is sent into the boiler, generating steam. Steam is used by a turbine for power generation. Average electric power generation ~2.2 MW. The residual steam/condensate is used in greenhouses located in the neighbourhood.

The pyrolysis facility operation is monitored and controlled from the control room.

This pyrolysis plant annually treating about 35000 tons of MSW practically demonstrates the most efficient and environmental friendly approach for the management of municipal waste.
