The pyrite rock is grinded into fine powder using mills and is then sent to the furnace (Stream F) where all sulphur in the ore is burned completely with air (Stream A) by flash combustion. Air is 10% in excess. All iron ( Fe ) in the ore forms Fe3O4 (solid waste product). The solids and gasses (Stream P1) formed in the furnace are sent to the cyclone (a plant equipment which uses centrifugal forces to separate solid substances from gasses) which separates the cinder (Stream C,Fe3O4 solid waste product and inerts) from gases (Stream P2). A negligible amount of SO3 occurs in both the cinder (Stream C) and the product gas (Stream P2). The product gas (Stream P2 ) is passes through a milk of lime (Steam L) in the absorbers to produce calcium bisulfite pulping liquor. The milk of lime liquid (Stream L) contains 40 mole %CaO and 60 mole %H20. An absorber is a plant equipment that brings gas and liquid streams into contact so that compounds of interest or contaminants in the gas phase ( SO2 in this case) are absorbed into the liquid phase as a result of their interaction. There are packings in the absorber to ensure that there is enough contact time between the liquid phase and the gas phase. The following reaction, forming calcium bisulphate, is taking place in the absorber: CaO+2SO2+H2OCa(HSO3)2 The CaO in the milk of lime is fed in stoichiometric proportions, meaning that there is no CaO in the calcium bisulphate liquor product. The exit gas from the absorber analyses: As a basis, divide your student number by 1000 and use this number in kg/hr as yo pyrite ore in the feed. For example, if your student number is 218123456 then The pyrite rock is grinded into fine powder using mills and is then sent to the furnace (Stream F) where all sulphur in the ore is burned completely with air (Stream A) by flash combustion.
