3-2 Black Liquor Evaporator Design and Operation
3.2-2 Different two-phase flow schemes are created in the boiling zone, including slug flow, where a slug of liquor is followed by a slug of vapor, similar to the perking in a coffee percolator; annular flow, where a ring of liquor encases a center core of vapor and liquid mist; and mist flow, where vapor blankets the tube surface. Mist flow conditions should be avoided because poor heat

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.
