Descrizione dell’invenzione industriale avente titolo: Description of the industrial invention entitled:
“Procedimento ed impianto per la produzione di energia da una fonte rinnovabile” "Process and plant for the production of energy from a renewable source"
Descrizione del trovato Description of the finding
La presente invenzione si riferisce ad un procedimento e ad un impianto per la produzione di energia da una fonte rinnovabile secondo i preamboli delle rivendicazioni 1 e 4, The present invention refers to a process and a plant for the production of energy from a renewable source according to the preambles of claims 1 and 4,
Come noto, attualmente gii impianti a biogas, utilizzanti una digestione anaerobica, per la produzione di energia elettrica e/o termica stanno avendo un grande sviluppo in Europa e nel mondo in seguito al notevole interesse nelle energie rinnovabili. D’altro canto il rendimento di questi impianti è proporzionale al contenuto di biomassa, laddove il contenuto minimo richiesto di biomassa di buona qualità (ovvero ricca in zuccheri, grassi, alcoli, ecc.) è di almeno il 15% della massa trattata come input per ottenere un buon rendimento economico del processo. Tuttavia le difficoltà nella disponibilità continuativa di masse presentanti una sufficiente percentuale di biomassa di buona qualità limitano in pratica Γ implementazione di questi impianti a biogas. As is known, currently biogas plants, using anaerobic digestion, for the production of electrical and / or thermal energy are having a great development in Europe and in the world following the considerable interest in renewable energies. On the other hand, the yield of these plants is proportional to the biomass content, where the minimum required content of good quality biomass (i.e. rich in sugars, fats, alcohols, etc.) is at least 15% of the mass treated as input. to obtain a good economic performance of the process. However, the difficulties in the continuous availability of masses with a sufficient percentage of good quality biomass limit in practice Γ implementation of these biogas plants.
E’ parimenti noto l’ottenimento di biocombustibili partendo da coltivazioni di cereali, soia, mais, ecc., come pure olio di palma o di jatropha, la qual cosa sottrae grandi superfici coltivabili, sinora utilizzate, ovvero utilizzabili, per la produzione di generi alimentari per l’uomo e gli animali, con il noto risultato del continuo rincaro di questi ultimi. It is also known to obtain biofuels starting from the cultivation of cereals, soybeans, corn, etc., as well as palm or jatropha oil, which subtracts large arable areas, used up to now, or usable, for the production of food for humans and animals, with the well-known result of the continuing increase in the price of the latter.
E’ pure noto che le alghe e le microalghe hanno una più rapida crescita rispetto alla soia, mais e così via e potrebbero pertanto costituire buoni fornitori di biocombustibili ed inoltre non disturberebbero il ‘'mercato agricolo” richiamato più sopra, laddove tuttavia l’estrazione dell’olio dalle microalghe è complicato ed oneroso. It is also known that algae and microalgae have a faster growth than soybeans, corn and so on and could therefore constitute good suppliers of biofuels and moreover they would not disturb the "agricultural market" mentioned above, where however the extraction oil from microalgae is complicated and burdensome.
E’ inoltre nota l’elevata emissione di gas serra da parte sia delle nazioni più industriali che da parte delle nazioni emergenti, con le conseguenti influenze e variazioni climatiche, riscaldamenti marini, formazione di tifoni, onde anomale e cosi via, nonché il pagamento di quote di C02 o “certificati verdi” da parte delle nazioni producenti 002 in eccedenza a favore di nazioni più virtuose. It is also known the high emission of greenhouse gases by both the most industrial and emerging nations, with the consequent influences and climatic variations, marine heating, typhoon formation, anomalous waves and so on, as well as the payment of quotas of C02 or "green certificates" by nations producing 002 in excess in favor of more virtuous nations.
A titolo di esempio, e relativamente alle persone, si indica che come media calcolata su una persona che vive in una famiglia media dì 3 persone consuma 35 € al bimestre per energia elettrica, 40 € al mese per consumo di gas, ed usa treno e mezzi pubblici per 300 km/mese, comporta una emissione di 90 g di C02 per ora. By way of example, and with regard to people, it is indicated that as an average calculated on a person living in an average family of 3 people, he consumes € 35 per two months for electricity, € 40 per month for gas consumption, and uses trains and public transport for 300 km / month, involves an emission of 90 g of C02 per hour.
Gravi impatti ambientali in termini di produzione di C02, scarti alimentari ed agricoli, rifiuti solidi urbani, e così via, si verificano poi nel caso di grandi concentrazioni locali di persone per lunghi periodi. Ad esempio nel caso della prossima EXPO di Milano del 2015 si possono indicare i seguenti parametri: Serious environmental impacts in terms of C02 production, food and agricultural waste, urban solid waste, and so on, then occur in the case of large local concentrations of people for long periods. For example, in the case of the next EXPO in Milan in 2015, the following parameters can be indicated:
visitatori previsti: 15-30 milioni expected visitors: 15-30 million
durata: 6 mesi duration: 6 months
area occupata: 1.100.000 m2. occupied area: 1,100,000 m2.
Calcolando 15.000.000 di visitatori con una durata media di visita dì 8 ore risulta una emissione complessiva di C02 di 10,80 tonnellate. Calculating 15,000,000 visitors with an average length of visit of 8 hours, an overall C02 emission of 10.80 tons results.
Come facilmente immaginabile, l’impatto ambientale nel caso di forti e prolungate concentrazioni di persone, come per esempio durante fiere ed esposizioni è di per sé molto negativo, e lo sarà in particolare nel caso della Expo di Milano, se affrontato con i mezzi attualmente disponibili. As easily imaginable, the environmental impact in the case of strong and prolonged concentrations of people, such as during fairs and exhibitions is in itself very negative, and it will be particularly so in the case of the Milan Expo, if faced with the means currently available. available.
Alla base della presente invenzione è posto il compito di indicare, in particolare per forti concentrazioni di persone, un procedimento ed un impianto per la sua attuazione in grado di demolire la €02 formata nella combustione di biogas formato dalla trasformazione di sostanze organiche, nonché di eventuali sfalci di prati locali prodotti, ed in grado dì fornire una elevata produzione di energia elettrica e dì ossigeno, nonché di compost, con l’ausilio di una fonte rinnovabile e con un impatto ambientale praticamente zero. The purpose of the present invention is to indicate, in particular for high concentrations of people, a process and a plant for its implementation capable of demolishing the € 02 formed in the combustion of biogas formed by the transformation of organic substances, as well as of possible mowing of local lawns produced, and able to provide a high production of electricity and oxygen, as well as compost, with the help of a renewable source and with a practically zero environmental impact.
Questo compito viene risolto, secondo l’invenzione, con un procedimento ed un impianto che presentano le caratteristiche delle rivendicazioni 1 e 4. Nel procedimento ed impianto secondo Γ invenzione si sfrutta la conoscenza secondo la quale le alghe e microalghe catturano la €02, emettono 02 ed hanno una rapida crescita che è di circa 10 volte più veloce rispetto alla soia, cereali e così via, la qual cosa permette vantaggiosamente di utilizzare le alghe stesse quale fonte dì energia rinnovabile in un ciclo chiuso, con l’impiego di un noto digestore anaerobico. This task is solved, according to the invention, with a process and a plant that have the characteristics of claims 1 and 4. In the process and plant according to the invention, the knowledge according to which algae and microalgae capture the € 02, emit 02 and have a rapid growth that is about 10 times faster than soybeans, cereals and so on, which advantageously allows the algae to be used as a renewable energy source in a closed cycle, with the use of a known anaerobic digester.
L’insegnamento di base dell’invenzione è quindi quello di integrare, secondo due varianti, l’impiego di: The basic teaching of the invention is therefore to integrate, according to two variants, the use of:
1 ) microalghe, le quali catturano la €02 e liberano 02, 1) microalgae, which capture € 02 and release 02,
2) utilizzare ulteriormente le alghe prodotte come alimento per un digestore anaerobico in modo diretto, 2) further use the algae produced as food for an anaerobic digester directly,
3) recuperare la €02 prodotta dalla combustione del metano o biogas prodotto dalla digestione anaerobica fissandola, con l’energia solare, come nuove alghe ed emettere ossigeno. 3) recover the € 02 produced by the combustion of methane or biogas produced by anaerobic digestion by fixing it, with solar energy, as new algae and emitting oxygen.
Le due varianti menzionate verranno descritte più dettagliatamente nel seguito. The two variants mentioned will be described in more detail below.
Un ulteriore vantaggio dell’invenzione consiste nel fatto che per l’attuazione delle fasi previste dal procedimento proposto sono utilizzabili dispositivi in principio appartenenti alla tecnica nota. A further advantage of the invention consists in the fact that devices in principle belonging to the known technique can be used for the implementation of the steps provided for by the proposed procedure.
Ulteriori caratteristiche e vantaggi del procedimento e dell’ impianto secondo l’invenzione sono rilevabili dalla descrizione seguente di due esempi di esecuzione illustrati schematicamente a titolo esemplificativo nel disegno allegato, nel quale mostrano: Further features and advantages of the process and of the plant according to the invention can be seen from the following description of two examples of execution schematically illustrated by way of example in the attached drawing, in which they show:
la figura 1 il ciclo chiuso del procedimento secondo l’invenzione, la figura 2 una prima forma di esecuzione di un impianto secondo l’invenzione, e Figure 1 the closed cycle of the process according to the invention, Figure 2 a first embodiment of a plant according to the invention, and
la figura 3 una seconda forma di esecuzione di un impianto secondo l’invenzione. Figure 3 is a second embodiment of a plant according to the invention.
Si fa dapprima riferimento alla fìg. 1, dalla quale sono rilevabili i componenti principali di un impianto per realizzare le diverse fasi del procedimento proposto, e più precisamente con 1 è indicato uno stadio di fotoreattori, con 2 un di gestore anaerobico o stadio di formazione di biogas e con 3 un co-generatore o stadio di produzione di energia elettrica e di C02. Reference is first made to fig. 1, from which the main components of a plant to carry out the different phases of the proposed process can be detected, and more precisely with 1 a photoreactor stage is indicated, with 2 an anaerobic manager or biogas formation stage and with 3 a co -generator or stage for the production of electricity and C02.
Più in dettaglio i fotoreattori dello stadio 1 sono formati da tubi trasparenti nei quali percola acqua e viene ricevuta la luce solare per far crescere le microalghe. Le alghe così prodotte vengono poi utilizzate direttamente come alimento per il di gestore anaerobico 2 a valle. Inoltre, per avere una grande superficie di coltivazione delle microalghe nello stadio 1 è prevista una pluralità di fotoreattori. More in detail, the photoreactors of stage 1 are formed by transparent tubes in which water percolates and sunlight is received to make the microalgae grow. The algae thus produced are then used directly as food for the downstream anaerobic manager 2. Furthermore, in order to have a large cultivation surface of the microalgae in stage 1 a plurality of photoreactors is provided.
Il digestore anaerobico 2 è un grande serbatoio nel quale vengono convogliate direttamente le alghe prodotte ed inoltre i diversi materiali organici come resti di cibo, rifiuti, altri scarti organici, sfalcio , e così via, e nel quale avviene la trasformazione di detti materiali organici in metano o biogas. The anaerobic digester 2 is a large tank in which the algae produced are directly conveyed and also the various organic materials such as food remains, waste, other organic waste, mowing, and so on, and in which the transformation of said organic materials into methane or biogas.
Nel co-generatore 3 viene poi bruciato il biogas formato nel digestore anaerobico 2 per la produzione di energia elettrica in modo noto e si forma C02. In the co-generator 3 the biogas formed in the anaerobic digester 2 is then burned for the production of electricity in a known way and C02 is formed.
La C02 così prodotta non viene scaricata nell’atmosfera ma, secondo Linvenzione, viene fissata, con l’energia solare, come nuove alghe, le quali durante la loro vita emetteranno ossigeno, che verrà poi scaricato The C02 thus produced is not discharged into the atmosphere but, according to the invention, is fixed, with solar energy, as new algae, which during their life will emit oxygen, which will then be discharged
nell’ atmosfera, con il vantaggio di arricchire l’aria ambiente. in the atmosphere, with the advantage of enriching the ambient air.
Viene così chiuso su sé stesso il ciclo del procedimento proposto secondo l’insegnamento dell’ invenzione, il quale può essere attuato con impianti rilevabili dalle due forme di esecuzione illustrate nelle figure 2 e 3. The cycle of the procedure proposed according to the teaching of the invention is thus closed on itself, which can be implemented with systems detectable by the two embodiments illustrated in Figures 2 and 3.
L’impianto illustrato in fig. 2 rappresenta la combinazione di cui ai punti precedenti 1 e 2. Esso presenta il vantaggio che la nota cogenerazione di energia elettrica da scarti è di per sé già considerata a tutti gli effetti energia da fonti rinnovabili, e quindi a complessivo impatto ambientale zero, poiché l’anidride carbonica prodotta sarebbe stata prodotta semplicemente anche scaricando gli scarti direttamente in discarica, o in un impianto di depurazione, ma senza la possibilità di recuperare energia elettrica. Il recupero, secondo l’invenzione, permette anche di ridurre ulteriormente i consumi di energia che sarebbero stati necessari per lo smaltimento di detti scarti in discarica. The system illustrated in fig. 2 represents the combination referred to in the previous points 1 and 2. It has the advantage that the well-known cogeneration of electrical energy from waste is in itself already considered to all intents and purposes energy from renewable sources, and therefore with an overall zero environmental impact, since the carbon dioxide produced would also have been produced simply by unloading the waste directly in landfills or in a purification plant, but without the possibility of recovering electricity. The recovery, according to the invention, also allows to further reduce the energy consumption that would have been necessary for the disposal of said waste in landfills.
con questa variante si ottiene il doppio vantaggio di: with this variant you get the double advantage of:
- trasformare la C02 dell’aria in ossigeno, e - transform the C02 of the air into oxygen, e
- trasformare le alghe generate dalla C02 in energia elettrica. - transform the algae generated by C02 into electricity.
La seconda variante illustrata in fìg. 3 è formata dalla prima variante della fig. 2 alla quale è aggiunta la fase 3. The second variant illustrated in fig. 3 is formed by the first variant of fig. 2 to which step 3 is added.
Con questa variante si può ottenere una rimozione completa, o parziale, anche della C02 emessa dalla combustione delle fonti rinnovabili, e pertanto un bilancio ancora più positivo di riduzione del gas effetto serra, come pure un aumento dell<5>ossigeno nell<5>aria ambiente. With this variant it is possible to obtain a complete or partial removal of the C02 emitted by the combustion of renewable sources, and therefore an even more positive balance of greenhouse gas reduction, as well as an increase in oxygen in the <5> ambient air.
Un ulteriore vantaggio è che con l’insegnamento dell’ invenzione come materiale di scarico del di gestore si ottiene un compost di elevata qualità. Si osserva inoltre che l’energia elettrica prodotta può essere utilizzata vantaggiosamente per il rafffescamento in estate ed il riscaldamento in inverno di edifici, ad esempio della EXPO, o in parte venduta. A further advantage is that by teaching the invention as a waste material for the operator, a high quality compost is obtained. It is also noted that the electricity produced can be used advantageously for cooling in the summer and heating in the winter of buildings, such as the EXPO, or partly sold.
Come dati tecnici con riferimento ad un impianto per la Expo si precisa che: As technical data with reference to a plant for the Expo it is specified that:
relativamente alle alghe, per ogni ettaro di superficie alla quale si sostengono e crescono le alghe si producono circa 60 t/anno di materia secca, equivalenti a circa 30 1 di carbonio/ha/anno pari a 110 t/ha/anno di C02 rimossa. with regard to algae, for each hectare of surface on which the algae sustain and grow, about 60 t / year of dry matter are produced, equivalent to about 30 1 of carbon / ha / year equal to 110 t / ha / year of C02 removed .
La superficie di alghe richiesta per la Expo è dell’ordine di 980.000 m2, mentre la superficie occupata dai fotoreattori è di 31,000 m2. The surface area of algae required for the Expo is of the order of 980,000 m2, while the surface occupied by the photoreactors is 31,000 m2.
Nel caso della Expo inoltre, dopo il termine dell’esposizione, con un impianto secondo Γ invenzione si possono ottenere i seguenti vantaggi: Furthermore, in the case of the Expo, after the end of the exhibition, the following advantages can be obtained with a system according to the invention:
- mantenere Milano con impatto zero per 30.000 persone per tutto l’anno, - maintain Milan with zero impact for 30,000 people throughout the year,
- oppure mettere sul mercato (C02 trading) ca. 10,800 tonnellate ogni anno, (ricavo delle quote di C02 per 1 - 1,5 milioni di € per anno), - garantire ai milanesi aria più pulita, - or put on the market (C02 trading) approx. 10,800 tons every year, (revenue from C02 quotas for 1 - 1.5 million € per year), - guarantee the Milanese cleaner air,
- produrre ogni anno ca. 8.760 MWh di energia elettrica pulita (ricavo dell’energia elettrica prodotta per 1,6 milioni di € per anno, ovvero quota certificati verdi più energia elettrica venduta a 180 €/MWh), - generazione di riscaldamento/rafffescamento di alcuni padiglioni dell’ Expo. - produce approx. 8,760 MWh of clean electricity (revenue from electricity produced for € 1.6 million per year, or share of green certificates plus electricity sold at € 180 / MWh), - generation of heating / cooling of some pavilions of the Expo .
Dalla descrizione funzionale e strutturale del procedimento e degli impianti secondo l’invenzione è rilevabile che con gli stessi si risolve efficacemente il compito indicato e si ottengono i vantaggi indicati.
