Natural gas is essential both as a clean energy source and as a chemical feedstock in the manufacture of plastics. However, before it reaches the consumer, it has to go through many steps known as processing natural gas. These steps are essential for recovering valuable components contained in the gas and the efficient transport of gas over long distances via the pipeline.

Processing natural gas is a tricky industrial process utilized to purify natural gas that is extracted from underground gas fields. This process separates impurities and other non-methane fluids and hydrocarbons to produce pure methane (CH4), also known as dry pipeline-quality natural gas. Commercial, Industrial, and even residential consumers utilize this processed natural gas as fuel.
Natural gas in its final state utilized by the consumer is very different from the type of gas found underneath the earth. Raw natural gas is full of impurities, whereas the final product after processing is pure methane. These impurities incorporate nitrogen, oil, hydrates, carbon dioxide, water vapor, hydrogen sulfide, and heavy hydrocarbons that consist primarily of butane, pentane, ethane, and propane.
While some of this processing is completed at the well site, the other process is completed at the processing plant. Before natural gas enters the pipeline, eliminating most or all impurities is still required. Processing natural gas as a whole requires several separate steps; however, there are four primary processes: oil, water, condensate removal, hydrogen and carbon dioxide removal, dehydration, and the removal of NGL.
The natural gas utilized by consumers in its final state varies significantly from the natural gas underground. The final product contains almost pure methane; however, raw natural gas contains a variety of impurities. Impurities incorporate carbon dioxide, hydrogen sulfide, oil, water vapor, nitrogen, hydrates, and heavier hydrocarbons, consisting mostly of ethane, butane, propane, and pentanes. Gas processing, handling, and distribution companies like AG&P – a leading LNG platform provider in Asia and Africa – bring it to the form needed for consumer and commercial consumption. Joseph Sigelman, the CEO of AG&P, is one of many energy experts investing in building an LNG infrastructure that is both accessible and environmentally friendly. This process is taking place throughout the world as countries need more sustainable energy solutions.
While some gas treatments are done at the well site, the final processing takes place at a gas processing plant. Removal of all or most impurities is needed before entering the pipeline. Even though natural gas processing has several steps, the primary processes include separation, carbon dioxide and hydrogen sulfide removal, dehydration, and NGL recovery.
As the world strives to diversify its energy mix into a single source, natural gas and the natural gas process are increasingly becoming important.
Not only is natural gas viewed as “lower carbon” contrasted to other fossil fuels, but the construction of natural gas process plants is also considered to be relatively quick (2 years). Thus, the International Energy Agency (IEA) forecasts the share of natural gas in the global energy mix to increase up to 2% annually until 2020.
This growth has increased natural gas dependency in a variety of uses. For example, natural gas is used in the power sector and industrial heat generation, ammonia in fertilization, and LNG in the transportation division for long-haul trucks or CNG (compressed natural gas).
