The Recovery Tower & Column is a vital separation device in industrial processes, designed to recover valuable solvents, chemicals, or unreacted raw materials from process streams. By enabling efficient recycling and reuse, it helps reduce waste, lower operating costs, and improve sustainability. As an integral part of chemical and petrochemical plants, it contributes to resource efficiency, environmental compliance, and operational reliability.
WSHI designs and fabricates a wide range of process towers and columns for recovery, distillation, absorption, stripping, and chemical reaction applications. Engineered to perform under high pressures, broad temperature ranges, and corrosive conditions, our towers are applied in petrochemical, refining, chemical, fertilizer, and energy industries. With advanced engineering capabilities and precision manufacturing, WSHI provides durable and efficient solutions tailored to the most demanding industrial requirements.
| Type | Description |
| Solvent Recovery Column | Recovers reusable solvents from process streams via fractional condensation or distillation |
| Acid Gas Recovery Tower | Removes HCl, SO₂, CO₂ from gas streams using reactive absorbents or solvents |
| VOC Recovery Tower | Captures volatile organic compounds (VOCs) from exhaust gases, especially in chemical or pharmaceutical plants |
| Steam Condensate Recovery Tower | Separates and recycles steam condensate from process vapors |
| Amine Regeneration Tower | Regenerates amine solvents used in CO₂ or H₂S absorption processes |
| Alcohol Recovery Tower | Recovers ethanol, methanol, or isopropanol from production waste or reaction systems |
Certified Safety, Reliable Quality, Custom-Engineered Pressure Vessels.
— Globally Compliant, Built for Harsh Industrial Conditions.
The Recovery Tower & Column is designed to capture and recycle valuable raw materials, solvents, and unreacted gases from industrial process streams. By enabling efficient recovery, these towers help reduce waste, cut operational costs, and enhance sustainability. With optimized internal structures and corrosion-resistant materials, Recovery Towers ensure safe, continuous, and reliable operation even under demanding chemical and petrochemical conditions.
