Complete set of natural gas purification equipment

Natural gas, as a modern energy source, has the characteristics of cleanliness, efficiency, and high quality, and is an important source of energy for both daily life and industry. With the advancement of national industrialization, the application of natural gas will gradually replace traditional high polluting energy sources, and its scope of application is becoming increasingly wide. However, the natural gas extracted from oil fields contains varying amounts of heavier hydrocarbons, as well as water vapor, sulfides (hydrogen sulfide), carbon dioxide, nitrogen, and non hydrocarbon gases, which are generally not suitable for direct use by users.

The natural gas purification device mainly removes hydrogen sulfide, water vapor, and condensate hydrocarbons from natural gas. The purified natural gas can only be delivered as commercial natural gas to users.

In the process of natural gas purification, many technologies and devices are utilized. Only by keeping up with the requirements can the purification process be put into use to meet national demand. This requires continuous optimization and development of natural gas purification technology to ensure the degree of natural gas purification, guarantee the safety of natural gas purification operations, and reap good economic and social benefits for enterprises.

The natural gas purification project mainly includes natural gas desulfurization, decarbonization, dehydration, etc.

The deacidification process (mainly referring to carbon dioxide and possible hydrogen sulfide) uses solvent absorption method, and the absorbent isMDEA； The dehydration process uses molecular sieves to remove trace amounts of water; The mercury removal process adopts the sulfur leaching activated carbon adsorption method;After natural gas purificationEnter the cold box for liquefaction.

Process selection of complete sets of natural gas purification equipment

As a raw material gas, natural gas must be purified before liquefaction. Removing acidic gases, moisture, and impurities from the raw gas, such asH₂S、CO₂TheH₂O. Hg, etc., to prevent them from freezing at low temperatures and blocking or corroding equipment and pipelines. Table 3.1-1 lists the pre-treatment standards and maximum impurity content for LNG plant feed gas.
