Abstract
Ovim se diplomskim radom htio proizvesti praškasti kalcijev klorid iz ljuske jaja primjenom kiselinske obrade ljuske jaja 5 % kloridnom kiselinom u šaržnom reaktoru volumena 15 L te slijednom proizvodnjom praškastog kalcijeva klorida primjenom sušenja raspršivanjem. Pronađeno je da se proces cjelokupnog otapanja ljuske jaja uz 100 %-tni prinos na kalcijevu kloridu postiže tijekom 3 h i 30 minuta. Daljnjom obradom dobivenih otopina koja je uključivala neutralizaciju i flokulaciju te ugušćivanje postignuto je uklanjanje dijela organske tvari prisut-ne u ljusci jaja, čime su otopine kalcijeva klorida dodatno pročišćene. Primjenom postupka sušenja raspršivanjem ugušćenih otopina kalcijeva klorida pri optimalnim uvjetima (protok pumpe 5 %; protok zraka 30 L/min; temperatura sušenja 210 °C) dobivena je praškasta sol bezvodnog kalcijeva klorida visokog stupnja čistoće i zadovoljavajuće zdravstvene ispravnosti, pri čemu je prinos iznosio 88 % na masu vlažne ljuske jaja, odnosno 102 % na suhu tvar ljuske jaja.
Abstract (english)
The possibility of the production of calcium chloride from eggshell waste in 15 L batch reactor, followed by spry drying of obtained calcium chloride solution was examined. In this respect eggshells were exposed to 5% hy-drochloric acid with complete transformation of eggshell calcium carbonate to calcium chloride (100% yield) during 3 h 30 min. Further treatment of calcium chloride solution including neutralization and flocculation followed by evaporation to the 1/10 of volume yielded partially purified calcium chloride solution with reduced amount of organic matter. Spry drying of such prepared solution at optimal conditions (pump flow 5%; air flow 30 L / min; drying temperature 210 °C) yielded anhydrous calcium chloride of high purity and satisfactory mi-crobiological safety. Production yield of calcium chloride was 88% per wet weight of eggshell waste, or 102% per dry matter of eggshell waste.
