The manufacturing of pressure vessels for absorption tower NMP equipment is a chemical equipment mainly used for separating and purifying liquid mixtures. It utilizes the difference in volatility of each component in the mixture to enrich light components at the top of the tower and heavy components at the bottom through multiple vaporization and condensation processes inside the tower, thereby achieving separation. Widely used in industries such as petrochemicals, pharmaceuticals, and food, it is an important key equipment in modern chemical production for separating crude oil, purifying drugs, and recovering solvents.
