Consult on the calculation methods for molecular sieve adsorption time and regeneration time
Thread Content
Dear brothers, sisters, uncles, and aunts, I am researching issues related to molecular sieves, and I’m unsure how to determine the adsorption time and regeneration time. I have installed a new dryer; the design institute provided the dimensions for it. However, the regeneration times and adsorption times specified by different molecular sieve manufacturers vary significantly. How should I calculate these values? Please advise.
What difference? ~~Let’s talk about it in detail~~
What molecular sieve? Let’s take a look at the required parameters for pressure, temperature, flow rate, and dew point
It is recommended that the original poster ask the adsorbent manufacturers; the calculations related to adsorption and regeneration involve many experimental parameters, such as adsorption heat and adsorption capacity, which vary depending on the type of molecular sieve.
We are a molecular sieve manufacturer. Do you have the specific dimensions of the drying tower? Only load molecular sieve? Do we still need to install active alumina? 17097229276
Where are you planning to use it? What process? What device?
The flow rate of the regenerated gas, as well as whether the heating time is appropriate, are determined by checking whether the cold-blow peak meets the specified standards.
Recently, when communicating with the manufacturers, it seems to me that their decisions are made arbitrarily; I’d like to verify this. For hot blowing, the key factors to consider are heat capacity, namely that of the container, the molecular sieve, and the ceramic balls, as well as 10% heat loss and the heat required for water desorption, right? For cold blowing, the main consideration is the removal of heat through cooling. The pressure drop is calculated using the Euler formula. Please give me some guidance. :P:P:P
