Evaluation of mass$-$flows

Evaluation of mass $($and cost$)$ flows

Take the following raw materials: sand, soda, limestone$,$ dolomite, corundum.

Calculate the economic effect per ton of molten glass when switching from soda to

caustic soda for the given container glass composition $(100\%$ batch$).$

Calculate for both options $($soda and caustic soda$)$ the batch$-$gas mass stream in

$kg$ per ton of molten glass when $50\%$ cullet is used.

Calculate the off$-$gas $($flue$-$gas$)$ mass stream without batch gasses at air$-$fuel and

oxy$-$fuel firing in $kg$ per ton of glass when $120m^3$ methane are needed per one ton

of molten glass. $($NTP$-$conditions! Assumption air: $80\%\frac{N_2}{20}\%O_2,$ assume

stoichiometric combustion!$)$
