Overview

Small natural gas purification device: The natural gas purification process basically includes processes such as raw gas deacidification, dehydration and mercury removal system. Firstly, the well gas that has been pre treated by the block enters the purification block directly. The deacidification process (mainly referring to carbon dioxide and possible hydrogen sulfide) adopts solvent absorption method, and the absorbent is MDEA; 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 purification, it enters the cold box for liquefaction.

Selection of natural gas purification process

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.
