Stripping column

Columns are used in the chemical industry for many different mass transfer processes with the required separation accomplished through countercurrent flow of liquid and vapour inside the column. Fractionation or distillation columns are used to separate various chemicals by the difference in their volatilities. Stripper, absorber and scrubber columns are used to separate and purify products, recover unreacted raw materials or valuable product from waste streams or to remove hazardous chemicals from vent and waste streams to prevent chemical emissions and to meet environmental regulations. Typical materials of construction for columns: a carbon steel, alloy, glass-lined, or fluoropolymer lined/coated shell, to ensure resistance to pressure or vacuum; internals, packings, trays, distributors to ensure chemical reactions. In presence of corrosive products, glass-lined columns offer required corrosion-resistant properties. The column shell is made of one or several glass-lined steel sections. The sealing at the body flanges of the different sections is using the Pfaudler Gasket System 3000 with UF3000 compound. The column shell can be supported either on brackets, rings, or skirts. Depending on the process, the different columns sections are jacketed or non- jacketed, insulated or non-insulated Glass lined columns are frequently combined with internals in ceramic or PTFE from the Edlon product line, such as: Miscellaneous random packings Liquid distributors, redistributors Bed supports/ limiters Support trays/sieve trays Bubble caps Liquid injection pipes
