Silicone composition and function
Thread Content
The circulation machine in our ammonia synthesis uses a protective gas system with a silica gel dryer. Could you please tell me, what is the general composition of silica gel? What is the working principle, how to absorb water - saturate - dehydrate?
The main component of silica gel desiccant is SiO 2 , which has a transparent or translucent solid spherical appearance. The unique microporous structure of SIO 2 forms capillary absorption and condensation to strongly absorb moisture, and does not deliquesce after absorbing moisture. Its drying principle: By physically adsorbing water molecules into its own structure or chemically absorbing water molecules and changing its chemical structure, it becomes another substance. parsing method: Increase the temperature or blow air to dehydrate.
2 Lu said in great detail that it is mainly used as a dryer and adsorbent. It is also widely used in analytical chemistry. Column separation relies on its interaction with resin.
So after the silica gel is saturated, is it heated or blown to turn the water molecules inside into water vapor and then released with the vent pipe? What is the general temperature control during regeneration?
