What is one goal of the sulfur and carbon dioxide removal process in fuel gas purification?

The goal of the sulfur and carbon dioxide removal process in fuel gas purification is primarily to protect pipelines and equipment. When fuel gas contains sulfur compounds or excessive carbon dioxide, it can lead to the formation of corrosive acids and other harmful compounds during combustion or in the presence of moisture. This corrosion can deteriorate pipelines and equipment, resulting in leaks, failures, and increased maintenance costs.

By removing these contaminants, the integrity and longevity of the fuel gas system are enhanced, allowing for safer and more efficient operation. Protecting equipment and pipelines from corrosive damage is crucial for maintaining system reliability and performance, as well as for complying with safety and environmental regulations. This process ultimately contributes to the overall efficiency and stability of fuel gas distribution and usage.
