As a Formaldehyde Production Plant, share with you. In formaldehyde
production technology, the packed tower is the key equipment in the formaldehyde
complete equipment, and it is also an indispensable equipment. It plays an
important role in the work process. In the formaldehyde complete equipment, the
packed tower mainly has the following performance characteristics:

First, strong production capacity
Under normal circumstances, if the design is more reasonable, then the
production capacity of the packing tower of the formaldehyde equipment can reach
a good state. Everyone should know that the mass transfer is done by the rising
vapor and the countercurrent contact of the liquid descending along the packing
surface relying on gravity.
Second, the pressure drop is small
In actual production, we will find that the smaller the pressure drop, the
lower the working pressure of the equipment. For most of the separated
substances, the lowering of the working pressure is conducive to the increase of
relative volatility. The separation work provided favorable conditions.
Third, the separation efficiency is high
In most cases, the properties of the substance to be separated are closely
related to the separation efficiency of the tower. In addition, the separation
efficiency of the tower will also be affected by the operating state, including
working pressure, ambient temperature and flow rate, as well as the type and
performance of the tower. Impact. In comparison, the working capacity of
industrial packed towers is limited. In practical work, the packed towers of
formaldehyde equipment are obviously the ideal choice.
Fourth, the operation flexibility is great
We usually require that the equipment has good adaptability, so-called
operational flexibility, which means that the equipment has a certain range of
adaptation to the load. The larger the range of the normal operating load of the
packing tower of the formaldehyde equipment, the greater the flexibility of its
operation and the wider the scope of application.
Fifth, the liquid holding capacity is small
In order to ensure normal operation, we also have certain requirements for
its liquid holding capacity. In fact, the liquid holding capacity refers to the
liquid holding capacity on the packing surface, internals or tray during normal
operation, which will change accordingly according to the change of operating
load. For the packed tower of formaldehyde equipment, its liquid holding
capacity should be controlled within 6%.
