The Fractionation Tower & Column（also known as Distillation Columns） is an essential separation unit in industrial processes, designed to separate mixtures into distinct components or fractions based on their boiling points. It provides precise control over vapor–liquid contact and ensures efficient distribution of heat and mass transfer, which is critical for obtaining high-purity products. Widely used in refining and chemical plants, it plays a vital role in improving product quality, maximizing resource utilization, and enhancing overall process efficiency.
WSHI designs and fabricates a full range of process towers and columns for fractionation, distillation, absorption, stripping, and chemical reaction applications. Built to withstand high operating pressures, wide temperature ranges, and corrosive environments, our towers are extensively applied in petrochemical, refining, chemical, fertilizer, and energy industries. With advanced engineering design, precision fabrication, and material expertise, WSHI delivers reliable and efficient solutions tailored to demanding industrial operations.
