Extraction Tower & Column

The Extraction Tower & Column is a key separation device in industrial processes, designed to achieve liquid–liquid separation through counter-current contact between two immiscible phases. It enables the selective recovery of valuable components from mixtures, while also enhancing process yield and reducing impurities. As a critical unit in chemical and petrochemical operations, it contributes to product purity, resource utilization, and operational efficiency.

WSHI designs and fabricates a full range of process towers and columns for extraction, absorption, distillation, stripping, and chemical reaction applications. Engineered to handle high pressures, wide temperature ranges, and corrosive media, our towers are widely applied in petrochemical, refining, chemical, fertilizer, and energy industries. With advanced engineering design and precision fabrication, WSHI provides durable and efficient solutions tailored to demanding industrial environments.
