Study Notes
- Natural gas processing is essential for separating impurities and hydrocarbons from raw natural gas for transportation and use.
- Natural gas can originate from oil wells (associated gas), gas wells (non-associated gas), or condensate wells (non-associated gas).
- Associated gas is found in association with crude oil reservoirs, often occurring in the same underground formations as oil deposits.
- Raw natural gas, obtained from wells, is impure and needs to be purified before transportation due to major pipeline restrictions.
- Impurities in raw natural gas include water, liquids, and nitrogen, which are removed through various methods like water removal, liquid removal, nitrogen removal, membranes, adsorption, and cryogenic processes.
- Water removal from natural gas is crucial to maintain natural gas quality standards and prevent corrosion. This is achieved through methods like dehydration, desiccant dehydration, or mechanical refrigeration.
- Nitrogen removal from natural gas is essential to boost energy content and improve combustion efficiency. This is typically achieved using pressure-swing adsorption (PSA) units.
- NGLs (natural gas liquids) are often extracted during the gas processing stage for further refining and commercial use.
- Natural gas processing plays a vital role in ensuring the cleanliness and safety of natural gas for various applications, such as heating, electricity generation, and industrial processes.
