Raschig ring is the earliest
developed random packing, named after
the German chemist
Friedrich Raschig. It's small tube cutting, which
outside diameter is equal to its height, providing a
surface for (re)evaporation of the most volatile part in
the
refluxing
distillate, typically 10 mm in diameter and 12 mm
long.
It's used
in commercial
fractional distillation towers to reduce pressure
loss (versus using trays), while maintaining good
efficiency and economy. Typically the change in pressure
(also called "delta p") is lower than in the case of
trays but slightly higher than for
structured packing.
With the characters of high
mechanical strength, high chemical stability, and excellent heat
endurance, Ceramic Raschig Ring can resist high temperature, acid
(except HF), alkali, salt and
various organic solvents. It's widely applied in various packing
towers of desiccation, absorption, cooling, washing, and regeneration in
industries of petrochemical, chemical, metallurgy, gas and oxygen
generation.
For raschig ring with big size over 100mm, it's usually filled in the
column orderly. If its size is less than 90mm, raschig ring is stacked
in the column randomly.
