Abstract

POSTUPAK ZA TRETIRANJE GASOM FOSFINOM RASTRESITOG MATERIJALA, iniciranog ili osetljivog na infekcije stetocinama time sto se stvara i odrzava atmosfera gasa fosfina hidrolizom metalnog fosfida vodenom parom za vreme skladistenja ili transportovanja, u zatvorenim prostorima kao sto su kontejneri, sudovi ili sanduci za skladistenje ili transport, silosi brodski prostori, vagoni za transport rastresitog materijala zeleznicom ili drumom, koji obuhvata kontrolisanu hidrolizu za period od 0,25 do 20 dana pogodnog metalnog fosfida koji moze da se hidrolizuje i stvara gas fosfin i prouzrokuje ili omogucuje da se gas fosfin prostire kroz celokupni rastresiti materijal i odrzava u koncentraciji i u trajanju podesenom za razaranje prisutnih stetocina pri cemu se prouzrokuje zatvoren ciklus strujanja gasa kroz rastresit materijal, kroz prostor ili prostore u kojima se gas fosfin oslobadja prema prostoru ili prostorima rastresitog materijala koji su udaljeni i na suprotnoj strani od prostora gde se fosfin oslobadja, a odatle nazad posebnim putem vraca se na pocetak kruzenja, naznacen time, sto se metalni fosfid, kao sto je A1P, Mg3P2 ili njihova smesa, u kolicini od 1,5-50 gr. tehnickog A1P po kubnom metru prostora skladista, najbolje 1,7 do 17 g/m3, ili ekvivalentna kolicina Mg3P2, unosi u kolicini koja stvara i odrzava koncentraciju fosfina PH3 letalnu za stetocine, i iznosi u proseku od 50 do 5000 dnm, pozeljno od 500 do 5000 dnm, za period od 2 do 28 dana, na temperaturi okoline, najpogodnije od 9 do 30 C, sto kruzno strujanje pocinje da se vrsi pre nego sto koncentracija fosfina dostigne granicu samozapaljivosti u blizini mesta gde se fosfin oslobadja, najpogodnije da koncentracija fosfina bude do 6000 dnm pH3, sto se kruznim tokom strujanja smanjuje koncentracija sto je najpogodnije da dodje do potpune izmene gasa u medjuprostoru za 8 do 80 minuta, sto je najbolje da kruzni tok obuhvata izmenu kolicine gasa do dva puta i koja kolicina iznosi pozeljno 30-150% od zapremine medjuprostora u rastresitom materijalu, sto se koncentracija smanjuje u toj zoni dok ne padne na vrednost manju ili jednaku prosecnoj koncentraciji u prostoru celog skladista, i sto se strujanje uzastopno ponavlja tako da se koncentracija fosfina ogranici na gornju granicu od pozeljno 6000 dnm, i sto se sadrzaj vlage regulise iz spoljnjeg izvora. Prijava sadrzi jos 11 patentnih zahteva.
