Butane is described as alkane compound with four carbon atoms, natural gas derivative. Common usage of butane is in kitchen torches, barbecue grills, and many other items. It can be found as a natural gas in deep within our earth ground.

It is also an extremely flammable hydrocarbon which is highly sought after for many different applications. Normal butane can be used for various applications like gasoline blending, as a fuel gas, and as a feedstock for the manufacture of ethylene and butadiene, as a key ingredient of synthetic rubber. Butane is used as a petrol component, as a feedstock for the production of base petrochemicals in steam cracking, as fuel for cigarette lighters and as a propellant in aerosol sprays such as deodorants.

Butane comes is extremely abundant in many parts of the world, this type of gas is relatively inexpensive to mine and produce. It is a fossil fuel, created over the course of millions of years by a complex process deep inside the earth from the remains of plants, animals, and numerous microorganisms.

Its production process involves the following steps

Removal of oil and Condensate: This process involves separation of gas from the oil where it dissolved, often using equipment installed near the well or source of the gas pocket.

Removal of Water: Besides petroleum, even gases also need to be separated from the water with the help of machinery at the surface. This is done by a dehydration process, either through absorption or adsorption process. The main concept of absorption comprises of water is absorbed into silicate or granules. Adsorption process, on the other hand, is the process where the gas binds to the surface of another solid or liquid in a condensed layer for further processing.

Glycol Dehydration Process

In this step, either diethylene glycol or triethylene glycol, absorbs water from the wet gas. The glycol particles get heavier, sink to the bottom of the contactor device, and it then removed. Now the water has been stripped out of the natural gas, it is then transported out of the dehydrator unit.

In the final step wet natural gas passes through two or more absorption towers which are filled with alumina or silica, the water is trapped, and the remaining dry gas pours out of the bottom of the towers
