Tall towers, 10 to 20 meters high, are used to purify and lighten the color of the cane juice. The juice is introduced at the top of the tower and sulfur dioxide vapor is introduced at the bottom. The sulfur dioxide rises up through the tower in a process called sulfitation. Gas is added at 120 to 200 pounds per million pounds of juice.

Clean coal is an energy that can generally be used as fuel, the fine coal of bituminous coal is generally used for coking. The main reasons of washing coal are as bellow: 1. Improve coal quality and reduce emissions of coal-fired pollutants. Coal washing can remove 50%-80% of ash and 30%-40% of total sulfur (or 60%~80% of inorganic sulfur) in coal.

It is a new type of ultra-fine detail crushing equipment with a good "layer pulverization" effect. The open-circuit crushing product has a granularity of millimeters, which can meet the requirements of "multi-breaking and less grinding" new technology, greatly reduce the energy consumption and steel consumption of the grinding process.

Fine particulates. Very small fragments of solid materials or liquid droplets suspended in air are called particulates.Except for airborne lead, which is treated as a separate category, they are characterized on the basis of size and phase (i.e., solid or liquid) rather than by chemical composition.For example, solid particulates between roughly 1 and 100 μm in …

Coal preparation, or beneficiation, is a series of operations that remove mineral matter ( i.e ., ash) from coal. Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

To get rid of calcium carbonate you'll either have to melt the sulfur and filter it hot, or go the toluene solution route.
