DAIER Product FAQ

Answers about DAIER tower packing, tower internals, mist eliminators and separation products.

+ What is tower packing used for?
Tower packing is used to improve gas-liquid contact efficiency in absorption, distillation, stripping and other mass transfer processes. DAIER supplies random packing and structured packing for different separation applications.
+ What is the difference between random packing and structured packing?
Random packing provides flexible installation and good fouling resistance. Structured packing offers lower pressure drop and higher separation efficiency when high performance is required.
+ How do I select the right tower packing?
Packing selection depends on tower diameter, gas and liquid loading, pressure drop requirement, separation duty and operating conditions.
+ How to choose metal, plastic or ceramic packing?
Material selection depends on temperature, corrosion condition, chemical compatibility and operating environment.
+ What packing sizes are available?
DAIER provides different packing sizes according to application requirements, including smaller sizes for higher efficiency and larger sizes for higher capacity.
+ What is a mist eliminator used for?
A mist eliminator removes liquid droplets from gas streams to reduce carryover and improve separation efficiency.
+ What is the difference between mesh pad and vane type mist eliminator?
Mesh pad mist eliminators are suitable for fine droplets and high separation efficiency. Vane type mist eliminators are commonly used for larger droplets and higher gas velocity applications.
+ How to select a suitable mist eliminator?
Selection depends on gas velocity, droplet size, operating temperature, corrosion condition and required removal efficiency.
+ What tower internals does DAIER provide?
DAIER supplies liquid distributors, redistributors, support grids, hold-down grids and customized tower internals.
+ What information is needed for tower internals quotation?
Please provide tower diameter, installation type, operating conditions, drawings and required materials.
