Gas Dryer are engineered to removes moisture content from natural gas.
Natural gas is discovered in the earth comes with a slight over pressure up to 80 bars, depending of the source of the natural gas. It is found at low pressure locked in the structure of coal and at high pressure below thick layers of rock and other soil.
As also water vapour is one of the ingredients present, which forms the natural gas, this gas is always saturated with water vapour. When the natural gas is expanded to a lower pressure for using it in burners or compressed to higher pressure, hydrates can be formed from the natural gas and the water vapour, which will clog pipelines and instrumentation in the pipelines.
To prevent the formation of hydrates the natural gas has to be dried before processing it in pipelines and compressors or expander machines.
The most common and economical way of drying the natural gas is by reducing the dew point temperature which can be done by installing a Compressed Gas Dryer.
Delair is the 1st company in India to manufacture Compressed Gas Dryer.
