A solution of MgSO4 containing 43 grams of solid per 100 grams of water is fed to a vacuum crystallizer at 220°F. The vacuum in the crystallizer corresponds to a water boiling temperature of 43°F and a saturated solution of MgSO4 has a boiling point elevation of 7°F. How many pounds of Epsom salt (MgSO4 •7H2O) can be produced per hour from a feed rate of 1 ton/hr? What percentage of MgSO4 in the feed is recovered as Epsom salt? Include a process diagram.
