Hydrogen Gas

Hydrogen Gas

S. S. Gas Lab designs and supplies complete hydrogen gas plants with cylinder filling facilities. On small scale, hydrogen is primarily produced from electrolysis of water in either Knowel's type mono polar cells or filter press type bi-polar cells known as electrolysers.

Here is the process for the production of hydrogen gas through electrolytic Knowel's cells

• Tanks and bells are welded by special quality electrodes to avoid the process embrittling between hydrogen and caustic soda.
• Bells are manufactured out of C.R.C. sheets that are specially recommended for caustic soda handling.
• The Asbestos diaphragm cloth is manufactured from 100% pure long fiber asbestos without cellulose core and closely woven to avoid pin holes.
• Extra length of cloth is provided at the bottom to guard against bye-pass of gases.
• Ebonite insulators are tested against warping under high temperature and they are checked by meger for infinity resistance.
• Nickelling of anodes is done under strict supervision for a minimum of .002 thick coarse deposit and each plate is tested chemically for pores.

There are so many details we take care of, like -

The performance and long life of the electrolyser depends on the quality of feed water. As only hydrogen and oxygen together with some water vapour escape from the electrolyser, each impurity introduced with the feed water will accumulate in electrolyte, i.e. chloride, sulphate and iron. The former two will have harmful effect on nickel metal which leads to heavy corrosion and the later will cause impure oxygen gas.

The Advantages of Hydrogen Gas Plants

There are numerous uses of hydrogen gas plant in various industries. Some of the major uses of the hydrogen gas plant are-

• Hydrogenation agent in production of Sorbitol and Mannitol & other chemicals.
• Protectiveness in the non-ferrous industry and acting as a reducing agent.
• Hydrogenation agent in the edible oil and margarine industry.
• Cooling agent for turbo-generators in power station.
• Filling gas for meteorological balloons.
• Gas for welding and cutting.
• Synthesis gas for ammonia synthesis in the chemical industry.
• Manufacture of semiconductors.
• Production of high purity metals.

The Oxygen thus generated in the precess of electrolysis too has a wide variety of application.
