The concentrate from an evaporation system is 5,870 lb/h of 35 wt% MgS04 at 180°F and 25 psia.

The concentrate from an evaporation system is 5,870 lb/h of 35 wt% MgS04 at 180°F and 25 psia. It is mixed with 10,500 lb/h of saturated aqueous recycle filtrate of MgSO4 at 80°F and 25 psia. The mixture is sent to a vacuum crystallizer, operating at 85°F and 0.58 psia in the vapor space, to produce steam and a magma of 25 wt% crystals and 75 wt% saturated solution. Determine the lb/h of water evaporated and the maximum production rate of crystals in tons/day (dry basis for 2000 lb/ton).
