Sulfur dioxide can be used for a variety of reasons during the processing of sugar cane or the production of molasses. Most commonly, sulfur dioxide is used to lighten the color of the molasses or to help extend its shelf life. It may also be used to help with the processing of sugar cane when the cane has been harvested at an early stage.

steel - steel - Billets, bars, and rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-high mill with box passes, as shown in A in the figure.
Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800 F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.
Oct 02, 2011 Kraft pulp mills have the potential of generating about 10 kg of biomethanol per ton of pulp from their digester and evaporator condensates. In most mills, the methanol is steam-stripped from the condensates along with other volatile compounds such as terpenes and sulfur compounds and burned in boilers or dedicated incinerators.
