Sulfur Condenser fog formation The mass velocity in the sulfur condenser tubes will be lower than design. When the tube velocity is too low, there is not enough turbulence within the tubes to cause the sulfur being formed to impinge on the tube wall and coalesce. The sulfur remains suspended in the gas phase as a fog or fine mist. This fog will

proper sulfur nutrition. The amount of sulfur in plants is similar to phosphorus in many cases, thus removal by crops can be sizeable especially when the entire aboveground portion of the crop is harvested. Sulfur removal by various crops is summarized in Table 1. Sulfur deficiency on growing crops is often mistaken for nitrogen deficiency.
meet various needs before, during fermentation and post-fermentation. Sulfur dioxide, as an example, is used both as an antioxidant and disinfectant at many stages in winemaking, in particular, to prevent fermentation starting prematurely and inhibiting the action of wild yeasts and bacteria. If the pH of the wine must is too high, tartaric acid is

Sulfur is a component of coal and other gasification feed stocks. Resulting sulfur compounds in syngas need to be removed in most gasification applications due to environmental regulations or to avoid catalyst poisoning. Whether it is electricity, liquid fuels, or some other product being output, sulfur emissions are regulated, and sulfur removal is important for this reason, along with the ...
