Absorption Column
Product Overview
Our Absorption Columns are large-scale process towers designed for gas–liquid mass transfer operations, widely used in petrochemical, chemical, refinery, and environmental treatment industries. Manufactured by our factory as an experienced pressure vessel and process equipment manufacturer, these columns are engineered to deliver high separation efficiency, stable operation, and long service life under demanding process conditions.
With strong heavy-fabrication capability, we supply absorption columns suitable for high-pressure, large-diameter, and tall-tower applications, meeting the requirements of complex industrial processes.
