Description of the waste generating technology

A füstgáz kéntelenítésből származó gipsz a hőerőművek kéményéből kikerülő füstgáz kén-dioxid tartalmának csökkentését eredményező technológia során keletkezik. A nedves és félszáraz kéntelenítési folyamat mellékterméke a gipsz.
Nagy tömegben, gyakorlatilag vegytisztán keletkezik, a füstgázok kén-dioxid tartalmának nedves, mészköves technológia alkalmazásával való csökkentése során, amit ipari méretekben ún. kéntelenítő berendezés alkalmazásával végeznek.
A gipsz a füstgáz kéndioxid-tartalmának csökkentését eredményező leválasztó technológia terméke. A mosótoronyban a felfelé áramló 120–130 °C-os füstgázba vizes mészkőszuszpenziót permeteznek be. A több szinten bepermetezett mosóoldat hatására a forró füstgáz lehűl, a kémiai reakciók eredményeként pedig a mészkő megköti a kéndioxid gázt, miközben kalciumszulfittá alakul. A mosóberendezés zsompjában összegyűlő szulfitiszapot állandó keverés közben, sűrített levegő bevezetésével, kalciumszulfáttá, azaz gipsszé oxidálják. A gipszszuszpenzió víztelenítése hidrociklonokkal és vákuum-szalagszűrőn történik. A kelettkezett gipszet gipszsilokban tárolják. Forrás: http://www.mert.hu/hu/fustgaz-kentelenites

Name of the waste/by-product
Füstgáz kéntelenítéséből származó gipsz
Components of the waste/by-product

Fő összetevői a kálcium és a kén (CaSO4.2H2O). A gipsz kőzetalkotó ásvány, mindenhol képződik, ahol szulfidásványok oxidálódnak és Ca is jelen van a környezetben.
A pontos összetételt a vegyi anyag tartalom pont alatt megadtuk.

Other characteristics of the waste/by-product

Szervetlen anyagokból áll, amelyek bekerülnek a biológiai rendszerkbe, elemkörforgalmakba, átalakulva vagy eredeti formában. A talaj szervetlen strukturális alkotóelemeibe, oxidokban, hidroxidokba és anyagásványokba beépülnek.
A gipsz kis mértékben vízoldható, oldhatósága és hidrolizálhatósága nagyban függ a környezetben jelen lévő többi anyagtól és iontól.
A gipsz szerves anyagokkal együtt hulladéklerakókban anaerob körülmények között hidrogénszulfid gáz termelését eredményezheti.

If harmful effect was measured, please, specify what was measured, which method was used, who did the measurement, and what was the result

Nagy fluorid tartalma lehet, ezért FGD-vel kezelt talajon termesztett növények akkumulálhatják a fluort, amely káros hatást gyakorolhat a növényekre és az állatokra. Ezt vizsgálták Álvarez-Ayusoa és munkatársai (2011) Spanyolországban egy spanyol széntüzelésű erőműből származó FGD-vel kezelt talajon [5].

Would it be suitable for soil reclamation in general?
Yes
Justification, references

Ca- és S- tartalmának köszönhetően javítja a talajok fizikai tulajdonságait.

Would it supply nitrogen, phosphorous and/or potassium to the soil?
No
Would it supply mesoelements (Ca, Cl, Fe, Mg, Na, S, Si) to the soil?
Yes
Justification, references

Savanyú talajhoz keverve csökkent az oldható Al tartalom, nőtt a Ca, így a Ca:Al arány csökkent. A lucerna szárazanyag-tartalma csökkent [6].Lúgos talajban csökkentette a pH-t, és a kicserélhető Na tartalmat növelte [7].

Sadakata (2004) Alkali Soil Reclamation with Flue Gas Desulfurization Gypsum in China and Assessment of Metal Content in Corn Grains, 13(1):65-80

Would it supply microelements (B, Co, Cu, Mn, Mo, Zn, V) to the soil?
Yes
Justification, references

A FGD gipsz eredetének függvényében, mivel esetenként tartalmazhat mikroelemeket is.

Would it provide sufficient amounts of special nutrients to the soil?
Yes
Justification, references

Kéntartalma miatt kénpótlásra alkalmas [8].

Would it increase the humus/organic matter content of the soil?
No
Would it suffice as a main component of growing media?
No
Would it suffice as an additive to growing media?
Yes
Justification, references

Mivel tápanyagforrás a növények számára, növeli a víztartóképességét a talajnak [7][12].

Would it be suitable for amending saline and sodic soils?
Yes
Justification, references

Ca-tartalma miatt [11][12].

No
Would it be suitable for production of geotechnical elements?
Yes
Justification, references

Szerkezetjavító hatása miatt.
