In order to have an idea about the gas dehydration process and, we ought to have a better understanding of the component that is being dehydrated. Despite being a very popular source of fuel, not most industries are familiar with the true face of natural gas. So, what exactly is Natural gas?

To give you the exact definition of Natural gas, it is basically a hydrocarbon gas that mainly consists of Methane or CH4 along with some other hydrocarbons in lesser quantities. Formed more than a million years back, this natural gas is the product of the sea and ocean organisms that sunk right into the ocean bottom and were stored beneath structures of sedimentary rocks. After getting subjected to some intense episodes of pressure and heat, the organisms went through a transformation phase and gave is the natural gas which is one of the most popular sorts of fuel for energy that we use.

Nowadays we get natural gas right under the rocks that are underground and are called reservoirs. There are tiny spaces present in between these rocks, these tiny spaces or pores are the places where natural gas gets normally stored along with water, oil and other components.

One of the most common ways of extracting natural gas is through the process of drilling the wells. With pieces of equipment that can penetrate the impermeable rocks, the natural gas is extracted using these artificial methods. When it comes to the different variations of the Natural gas such as the shale gas, sour gas, tight gas, methane hydrates, and coal beds, each of them has got their own standard process of extraction. Most people also find the natural gas trapped in the reservoirs along with oil and other components.

Moving on to the details, we have 2 different types of natural gas. These types are defined and differentiated on the basis of the methane content that they have. It is readily reflected in the formation processes that they both have.

The biogenic gas or more commonly known as the Dry gas has got more or less than 95% of methane in it. The formation of the dry gas is through the decaying process of bacteria in the shallow depths.

The other type of gas that we have is the Thermogenic one which consists of more than 95% of the methane. This type is popularly known as the Wet Gas. A low-quality version of the natural gas, it is generally formed in the places with high temperature. There are some other compounds such as Butane and Ethane in the Wet natural gas apart from the methane content.

These variations of natural gas are extracted and then used for different purposes. To understand how the entire Natural gas sweetening process design and simulation work, we need to have an idea about the uses of Natural gas first.
