Abstract
Magnesium vapor produced by carbothermic reduction of magnesia must be quenched to prevent back reaction with carbon monoxide. Laboratory research by the Bureau of Mines has shown how the quenching efficiency varies with carbon monoxide content when using natural gas, hydrogen, or nitrogen for quenching. Typically, the efficiency is about 87 percent with no carbon monoxide, drops irregularly to 75 percent at 15 percent carbon monoxide, and then decreases less rapidly to 50 percent at 100 percent carbon monoxide. Estimated costs are presented to show how quenching at higher ranges of carbon monoxide content might affect the capital and operating costs of the carbothermic process.
