Molecular Sieve Application |
| 1. 3A molecular sieve is
mainly applied to absorb water molecular in drying natural
gas and oil gases, especially in drying Catalystic Splitting
Decomposition Oil gases and Alkene. So it is usually used
as fine drying agent in medicine, food, glass industry and
so on. |
| 2. 4A molecular sieve is
mainly used to make static dehydration in airtight gas or
liquid system, it can remove the moleculars of ethyl alcohol,
hydrogen sulphide, carbon dioxide, ethylene, acrylica, and
also dry the alkane. |
| 3. 5A molecular sieve is
mainly applied to separate isomerism alkane. Meanwhile, it
can also absorb the moleculars which can pass through in 3A
and 4A molecular sieve and whose diameters are less than five
angstrom. Especially the result is very evident in the changing
pressure absorption system. |
| 4. 13X molecualr sieve
can absorb the moleculars which can pass through in 3A,4A
and 5A molecular sieve and whose critical diameters are very
large, such as hydrocarbon and isomerism alkane separation.
|
Molecular Sieve Regeneration |
| The regeneration gases
which are in common use are nitrogen, air, hydrogen and alkane.
The regeneration gases quantity is 0.2-1.2m3/h.kg or so, then
heated to 200°C--350°C, the outlet temperature is
150°C or so, continuously heated for 3--4 hours, then
put into the regeneration dry cool gases to cool to room temperature. |
