Absorption Tower

Product Description

An absorption tower is a commonly used equipment in the chemical industry, whose core function lies in achieving the effective separation of complex mixtures such as gases and liquids. This process is mainly completed through physical or chemical absorption methods, aiming to extract specific components. Absorption towers play an indispensable role in multiple industries such as petroleum, chemical engineering, and pharmaceuticals.

Core Types of Absorption Towers

1. Packed Tower
   • Internally filled with structured packing (such as metal orifice corrugated packing, plastic flower rings) or random packing (such as Raschig rings, Pall rings), where gas and liquid come into countercurrent contact through the packing surface.
2. Tray Tower
   • Consists of multiple trays (such as float valve trays, sieve trays, bubble cap trays), where gas bubbles through the liquid layer via openings or valves on the trays.
3. Spray Tower
   • No packing or trays; liquid is atomized through nozzles (nozzle pressure 0.1-0.5 MPa) to countercurrently contact rising gas.
4. Turbulent Ball Tower
   • The packing layer is composed of lightweight balls (such as polyethylene balls, polypropylene balls), and the balls turbulence at gas velocities of 2-6 m/s to strengthen gas-liquid mixing.
5. Bubble Column
   • Gas is bubbled through a distributor at the bottom of the tower, and the liquid remains stationary or flows slowly to form a gas-liquid mixed phase (bubble layer height accounts for 70%-80% of the tower body).

Core Advantages

1. High-Efficiency Separation Capability
   • Enhanced Mass Transfer Efficiency: Provides a large gas-liquid contact area through packing or trays, combined with countercurrent operation design, significantly improving the absorption rate of target components.
2. Outstanding Economy and Energy Efficiency
   • Low Energy Consumption Design: Uses low-resistance packing or high-efficiency trays, reducing energy consumption by 20%-30% compared to traditional equipment.
3. Long-Term Stable Operation
   • Corrosion-resistant materials (such as 316L stainless steel, Hastelloy) and lining processes (such as rubber, PTFE) ensure equipment service life (carbon steel material ≥10 years, stainless steel ≥20 years), reducing maintenance frequency.

Application Scenarios

Environmental Protection Sector：Flue Gas Desulfurization and Denitrification，Adopts processes such as the ammonia method and lime-gypsum method to remove SO₂ and NOx from flue gas, with emission concentrations ≤50mg/Nm³.

Chemical ProductionCarbon Dioxide Removal in Ammonia Synthesis，Uses MDEA solution to absorb CO₂ from synthesis gas, reducing its concentration from 15% to ≤0.1% to meet the requirements of subsequent ammonia synthesis.

Energy Industry：Natural Gas Acid Gas Removal，Removes acidic gases such as H₂S and CO₂ from natural gas, reducing the sulfur content to ≤4ppm to meet pipeline transportation standards.

Pharmaceutical and Food Industry：Solvent Recovery，Recovers solvents such as ethanol and acetone from reaction tail gases, reducing production costs and environmental pollution.
