Our system is modular and each gasifier can operate according to need either as a waste-to-energy plant, combustor or pyrolyzer. This is therefore an extremely flexible system, modular, capable of treating different matrices simultaneously and can be implemented, as needed, with further ancillary systems, able to maximize the efficiency of energy recovery.
Our gasification system involves the use of drying systems for pre-treating the incoming material or matrix. The dryer is fed through the process’ heat and allows to bring the input humidity of the matrix by the value of the conferral (normally value between 70% and 30%) to, approximately, 10%.
The matrix is dried in this way, is transported inside the reactor, where it is raised to temperatures ranging from 400 to 650 ° C, through the recovery of heat generated by the same syngas and by the same process of gasification that happens in the last part of the reactor. The waste is so subjected, quickly, to the total drying, pyrolysis and gasification.
The gas produced (syngas) is sent, after being washed and purified, to a turbine and / or endothermic engines and / or advanced ORC systems (EXAMPLE: From Heat to Energy) in which thermal kW and / or electric kW will be produced or methanol / DME can be obtained with ZEB. Part of the electricity will be used for self-sufficiency (about 15%), the other will be used to reduce the costs of other energy-intensive processes within the plant or sent into the national grid. If available, the heat can be used for drying or to power a district heating network or to produce cold thanks to inverters..
Once the gasification process has taken place, the only resulting waste product is ash, on average about 5-10% of the matrix entering the gasifiers. The part of the ash treated with the plasma will turn into a material that can be used for useful purposes without environmental risks.
In RINA Consulting - Centro Sviluppo Materiali spa, there is a pilot that can be visited, fully equipped with a plasma torch.
We plan to finish setting up our demo site in Italy in 2024 given the impossibility of showing existing working systems for safety-related issues.
