What is the origin of sulphur dioxide?

Answer 1

Although there are many potential sources of sulphur dioxide the primary concern is the comes from burning fossil fuels (coal and oil). The are referred to as "sour" fuels. Sulfur dioxide has the formula SO2. It is formed by burning sulfur, which is an impurity in coal and crude oil, with oxygen in the air.

In Industry:

• The burning of sulphur containing fuels (Bunker, coal, sour gas)
• The flaring of sour gas either at gas wells or at refineries
• The processing of sulphidic ores (pyrites)
• Fires at sulphur blocks (a storage system for bulk sulphur)

In Nature:

• Volcanoes

In the lab:

• Burning of sulfur

Answer 2

Sulphur Dioxide results from:

In Nature:

* The burning of sulphur containing fuels (Bunker, coal, sour gas) * The flaring of sour gas * The processing of sulphidic ores (pyrites) * Fires at sulphur blocks * Volcanoes

In the lab:

* Burning of sulfur

Answer 3

Sulphur Oxide (SO2) and Nitrous Oxide (NOx) comes from electric powered generated that relies on the burning of fossil fuelslike coal.
For example for thermal power units using fossil fuels, from heating installations with fossil fuels, from vehicles including planes, boats.

Answer 4

I'm uncertain whether or not you still want this answer. The question may have been up for a while, however i will answer it for future persons seeking the same knowledge. Now i'm sure that you know these oxides (sulphur and nitrogen) form

acid rain and that the sulphur harms the chlorophyll in plants, etc. but you are wondering where the actually oxides come from. Are there any sources?

Yes actually not exactly "sources" but; oxides of sulphur and nitrogen emitted from the burning of fossil fuels. The primary sources of these gases are: power stations, industrial boilers and vehicles. Oxides of nitrogen are released mainly from vehicles without catalytic converters.

Additional Information

Carbon monoxide are harmful to the environment in the same way (it does not however cause acid rain). Carbon monoxide is produced from incomplete combustion of fossil fuels, as a product (waste product) in a blast furnace and from the internal combustion of an engine(car fumes).

Answer 5

the exothermic reactions from the combustion of hydrocarbons in industry and engines causes heat which ca make the sulphur containing fuels (fossil fuels, natural gas etc) react with the oxygen in the surrounding air to form sulphur dioxide (SO2)

Answer 6

Sulfur dioxide is primarily produced by burning fossil fuels like coal and oil, as well as through volcanic eruptions and the metabolism of sulfur-containing compounds by some microorganisms. It is also a byproduct of various industrial processes like smelting metal ores and producing paper.

Answer 7

It is synthesized from sulphur and oxygen. It can also be found in the atmosphere near coal fired power stations.

Answer 8

Volcanoes produce more sulfur dioxide than any other cause. Some sulfur dioxide is also release from the burning of sulfur-rich fossil fuels.

Answer 9

Burning sulphur in air. It reacts with oxygen to form sulphur dioxide.
