STUDY OF THE KINETICS OF DRYING IRON (II) SULFATE HEPTAHYDRATE BY FILTRATION METHOD

The object of research: kinetics filtration drying process iron (II) sulfate heptahydrate.
 Solved problem: to obtain the calculated dependence drying, which predicts nature change in moisture content material time during period complete saturation thermal agent with range heights layer 30.10-3–120.10-3 m and speeds 0.46–1.61 m/s.
 Main scientific results: heptahydrate was investigated at different pressure drops over dry material, means movement agent. A certain critical content, is Wcr=0.065 kg H2O/kg mat it reaches Based on solution system differential equations balance kinetic coefficients for a=15.75 1/m, α=3.03.10-3 1/s were determined, made possible H=30.10-3–120.10-3 velocities υ=0.46–1.61 area practical application enterprises production titanium (IV) oxide as a by-product specializing manufacture pigments based Innovative technological product: tetrahydrate (FeSO4•4H2O, rosenite), obtained result by method.
 Scope innovative technology pigments.
