‌Regeneration Tower

Product Description

The regenerative tower is a key equipment for absorbent regeneration in chemical engineering, primarily used for desulfurization and dehydration of natural gas, as well as treatment of carbon dioxide solutions in synthetic ammonia production. Its function is to separate solutes from the absorbent and restore the absorbent to its initial state for recycling. Most commonly structured as packed towers, they typically use absorbents such as diethylene glycol and triethylene glycol, which feature high boiling points, stability, and easy regenerability. The main regeneration method is gas stripping, supplemented by techniques such as azeotropic regeneration and vacuum regeneration.

Product Types

• Desulfurization and Denitrification Regenerative Tower

Regenerates desulfurization and denitrification absorbents (e.g., activated carbon, ammonia water solutions) to release gases such as SO₂ and NOₓ for recycling or treatment.

Main applications: Flue gas treatment in coal-fired power plants and waste gas treatment in industrial kilns.

• Decarbonization Regenerative Tower

Regenerates CO₂ absorption liquids (e.g., MEA, DEA) to release high-purity CO₂ for storage or utilization.

Main applications: Carbon capture projects and natural gas decarbonization purification.

• Solvent Regenerative Tower

Regenerates organic solutions (e.g., methanol, ethanolamine) to recover solvents and separate solutes.

Main applications: Lubricating oil refining in petrochemical industry and acid gas removal in coal chemical industry.

Product Features

• Efficient Medium Regeneration: Enhances system recycling efficiency by achieving effective regeneration of media.
• Strong Structural and Process Adaptability: Meets multi-scenario requirements with flexible design and process compatibility.
• Reliable Equipment Performance: Ensures convenient operation and maintenance with stable functionality.
• Significant Energy Consumption and Economic Advantages: Optimizes energy efficiency and cost-effectiveness.
• Notable Environmental Benefits: Supports green production by reducing environmental impact.

Regeneration Methods

• Gas Stripping:Contact with hot stripping gas in the stripping section reduces water vapor partial pressure to concentrate glycol.
• Azeotropic Regeneration:Separates water through the formation and separation of azeotropic mixtures.
• Vacuum Regeneration:Utilizes reduced pressure to promote water evaporation.

Application Scenarios

• Gas Purification or Recovery:

Uses absorbents to remove harmful components from natural gas for purification (e.g., desulfurization/dehydration).

Extracts valuable components from gases using absorbents to obtain products (e.g., sulfuric acid absorption of sulfur trioxide to produce concentrated sulfuric acid).

• Gas Mixture Separation:

Separates components using organic solvents (e.g., absorption of benzene from coal gas).
