Column Trays are used as indispensable parts of distillation plants. These carbon steel made trays are completely corrosion proof. Application of these metallic trays can be noticed in various processing plants that include chemical industry. These trays act as gas liquid contactors where transferring of mass between gas phase and liquid phase is conducted. Column Trays are effective in maintaining precision of separation task. Factors like vapor distribution and liquid distribution are kept in mind while executing liquid and vapor separation process.
