Best Answer

Sulphur scrubbers on coal fired power plants use a multistage system:

  1. The stack gasses containing sulphur dioxide gas are passed over a catalytic bed with the addition of extra oxygen to convert the sulphur dioxide gas to sulphur trioxide gas.
  2. The stack gasses now containing sulphur trioxide gas are passed through a chamber containing water spray and the sulphur trioxide gas dissolves in the water producing highly concentrated sulphuric acid, which precipitates out of the stack gasses as a liquid.
  3. The concentrated sulphuric acid is concentrated more producing "Oleum" a very oily industrial grade of sulphuric acid. "Oleum" can often be sold to chemical companies with no further processing.
  4. If the market for "Oleum" does not offer enough demand, then it can be processed through additional steps to extract the dry sulphur as yellow crystals called "flowers of sulphur".

What are scrubbers in smokestacks?

Scrubbers use a wet limestone slurry to absorb sulfur as it passes though. Filters are large cloth bags that catch particles as they go through the cloth. Scrubbers are more common, and can reduce sulfur emissions by up to 90 percent, when working properly. Still, smaller particulates are less likely to be absorbed by the limestone, and can pass out the smokestack into the air. yehhh the answerr


How can we reduce your carbon footprint?

If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.


Would animals reduce co2 levels in the atmosphere?

No, only vegetation growing removes carbon dioxide from the atmosphere.


What has to reduce to solve the problem of global warming?

We have to reduce the emissions of carbon dioxide and methane, the greenhouse gases, into the atmosphere.


How can you reduce the amount of sulfur dioxide released?

Some types of coal contain sulphur, and when burned, release sulphur dioxide; this is the major source of sulphur dioxide emissions. There are ways to scrub pollutants out of the smoke emitted by coal-burning power plants, however, I personally think that it makes more sense to stop burning coal and switch to other methods of power generation.


What is the quickest way to reduce the build up of carbon dioxide in the atmosphere?

How can reducing sulfur content in fuel reduce acidic gas emission?

reducing the sulphur content in fuels will effectivily reduce the amount of sulphur realised into the atmosphere. In the gas phase sulphur dioxide is oxidised by reaction with the hydroxyl radical via an intermolecular reaction: SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water, sulphur trioxide (SO3) is converted rapidly to sulphuric acid: SO3(g) + H2O(l) → H2SO4(l) the lower the sulphur released into the atmosphere the lower the amount of sulphuric acid is formed

How can power plants help their air pollution problem?

Power plants need air scrubbers to help reduce sulfur dioxide. Too often factory owners put profit ahead of public safety.


How can factories be more green?

According to Experts, factories can reduce their reliance on fossil fuels in manufacturing settings to reduce their impact on global warming. In addition, factories should consider minimizing waste as well.


How will the level of carbon in the atmosphere change if humans do nothing to reduce their impact on the carbon cycle?

If humans continue doing nothing to reduce their impact on the carbon cycle then the levels of carbon dioxide in the atmosphere will continue to rise.
