304L Stainless Steel Structured Tower Packing
Metal perforated plate corrugated packing is made of materials like carbon steel, stainless steel ,etc.
It is widely used in the reactors in fine chemical industry, petrochemical industry, and fertilizer industry as mass transfer media and often used in difficult separation and the vacuum distillation of heat content, atmospheric distillation and absorption process.
stainless steel: 304, 304L,316, 316L
carbon steel: Q195, Q235
The most economical range is F-factor 1.5-2.0
Pressure drop of each theoretical sheet is 0.3-1 mbar
Minimum liquid load is 2001/m2h
A distributor should be installed for every 3-4 meters inside packing towers with diameters of more than 300 mm
High liquid & vapor loading, Column diameter could be designed smaller for new equipment and capacity could be
increased dramatically for existing column revamp.
High resistance to nearly all mineral and organic acids and derivatives, partly resistant to alkalis
High mass-transfer efficiency. Much higher specific surface area than random packing
Low pressure drop, considerable energy savings
Wide turndown ratio. Easy to scale up
Suitable for all sizes of column
Ceramic structured packing was not only widely used in coal gas washing tower, fertilizer heat gas saturation tower, naphthalene washing tower, ammonia washing tower, but also as the support for heat exchange machine , catalyst, and suit for a big tower rebuilding/revamp..
Fining process of corrosive mixtures, which have strict requirements for pressure drop and number of theoretical sheets.
Vacuum treatment under absolute pressure higher than 1 mbar.
Fining and distillation of halogen organic compounds.
