Can I burn sulfur for pest control?

Sulfur is burned or vaporized to control fungus, mites, or insects. When sulfur is burned, it turns into a gas called sulfur dioxide. The gas can mix with moisture on plants to form an acid that can damage plant leaves. Breathing the gas can be harmful to human health.

Flavorings-Related Lung Disease: Coffee Processing ...

To make ground coffee, there is a grinding step. The roasted product is then allowed to off-gas. Diacetyl, 2,3-pentanedione, other volatile organic compounds, and gases such as carbon monoxide and carbon dioxide are naturally produced during coffee roasting and released (off-gassed) during and after roasting.

Adjusting high soil pH with elemental sulfur - Agvise ...

Elemental sulfur must go through a transformation process called oxidation, converting elemental sulfur (S 0) to sulfuric acid (H 2 SO 4), a strong acid. Sulfuric acid does lower soil pH, but the problem is the amount of carbonate in the northern region, which commonly ranges from 1 to 5% CCE and sometimes over 10% CCE.

Desulfurization of Natural Gas for Fuel Cells

Typical amounts of sulfur in natural gas are between 1{5 parts per million by volume. Unfortunately, sulfur degrades the fuel cell components, and so must be ltered out of the natural gas feedstock. The gas that reaches the next component in the fuel cell must have sulfur levels as low as possible.
