the density of crystalline gypsum is 2.32 g per cubic centimetre. What volume of gypsum is generated per year? ( Infact the volume is several times larger because of the porosity of the gypsum produced)

Expert Solution

The disposal of by product gypsum (CaSO4 H20) is a significant problem for fertilizer manufacturers. A typical fertiliser plant may produce 100 metric tons of phosphoric acid per day by wet acid process. ( 1 metric ton = 10^3kg). What mass of gypsum is produced per year?

Given that;

A typical fertiliser plant may produce 100 metric tons of phosphoric acid per day by wet acid process.

1 metric ton = 10^3kg

So 100 metric ton = 100 metric ton * 10^3kg /1 metric ton

= 10^5 kg per day

One year = 365 days

10^5 kg per day *365 daays / 1 year

= 3.65*10^7 kg / year

= 3.65*10^10 g / year

= 36500 metric ton / year

the density of crystalline gypsum is 2.32 g per cubic centimetre. What volume of gypsum is generated per year? ( Infact the volume is several times larger because of the porosity of the gypsum produced)

density = mass/ volume

volume = mass/ density

= 3.65*10^10 g / year /2.32 g per cubic centimetre

= 1.57*10^10 cubic centimetre / year
