Hydrogen Gas Removal

Hydrogen makes up more than 90 percent of all atoms. It is prepared through the decomposition of certain hydrocarbons, electrolysis of water or heating carbon. Large quantities of hydrogen are required for nitrogen fixation, hydrogenation of fats and methanol production. Hydrogen fuel cells are used for generating large amounts of power. Today it is used mainly for chemical manufacturing, but in the near future it can also be used as a vehicle fuel to power hydrogen cars.

Hydrogen as a Fuel

• Today many people think that we need to depend on carbon-based fuels such as natural gas like propane, as these are cleaner and can clean the air pollutants but these fossil fuel supplies are limited. The only way to get rid of this is to use electric motors. Vehicles using electric motors get their power from hydrogen fuel cells. Hydrogen-powered fuel cells are the power source for a future generation of cars.

Processing Natural Gas

• Sulfur exists in natural gas as hydrogen sulfide gas. The process of removing hydrogen sulfide gas from natural gas is known as sweetening the gas. An "amine process" is used here to remove H2S which is called amine process. H2S gas which is also called sour gas is run through a tower containing amine solution. This will absorb sulfur components from natural gas. The amine solution used here can also be regenerated to treat more sour gas.

Removal of H2S Gas

• Carbons impregnated with triethylenediamine remove the hydrogen sulfide gas. Activated carbons without chemical saturation are less efficient than impregnated activated carbons in terms of gas removal. Activated hydrocarbons remove organic and inorganic contaminants. With the growing concern over environmental and hazardous effects of pollution there has been tremendous interest in activated carbons for removing pollutants from liquid and gas streams, used for the removal of hydrogen sulfide gas.

Moisture Removal from Hydrogen Chloride Gas

• Moisture removal from HCL gas is a purification technology. To determine the performance of a purifier in HCL gas requires various analytical tools. HCL gas is used in semiconductor devices for fabricating and cleaning the process chamber which is highly sensitive to contamination. Many considerations must be followed while selecting an appropriate purifier for HCL gas. The moisture should be removed to low parts per billion levels.

Removing H2S from Water

• If the water gives an odd odor like that of a rotten egg, then the water contains hydrogen sulfide. H2S may also be found in household hot water, in dug out and well water. There are various water treatment options for removing hydrogen sulfide like chlorination and sand filters, chlorination and activated carbon filters, aeration, manganese green sand iron filters and other oxidizing agents besides chlorine that can be added to water for removing hydrogen sulfide--hydrogen peroxide, ozone and potassium permanganate.
