What processes are included in the purification of fuel gas at a processing plant?

The purification of fuel gas at a processing plant involves several critical processes aimed at ensuring the gas meets safety, quality, and regulatory standards before it is delivered for use. The selected option includes the essential steps typically performed in this context.

Oil and condensate removal is crucial because these substances can impede the efficiency of gas processing equipment and affect the quality of the gas. Water removal is another integral process since moisture can lead to corrosion in pipelines and impair combustion efficiency. Separation of natural gas liquids is necessary to prevent these heavier hydrocarbons from mixing with the gaseous fuel, as doing so helps in managing the energy content and ensures compliance with gas specifications.

Additionally, the removal of sulfur compounds and carbon dioxide is vital. Sulfur can lead to corrosive damage in equipment, while carbon dioxide can lower the heating value of the gas. By eliminating these unwanted components, the purification process helps enhance the overall performance and usability of the fuel gas.

The other options listed do not accurately encapsulate the specific purification processes necessary for fuel gas. For instance, combustion and distillation are more relevant to other applications rather than gas purification. Similarly, processes like heating, cooling, mixing, and compressing do not directly relate to the removal of impurities, which is a primary focus in
