Removal of system moisture
Thread Content
During normal operation of methane chloride production equipment, moisture present in the raw materials causes water to accumulate in the storage tanks, and this amount keeps increasing. Silica gel is commonly used to remove this water, but the results are not very satisfactory. Does anyone have a better method for removing water? Thank you
There are many methods, along with specific quantities and control requirements. Active alumina, molecular sieves, phosphorus pentoxide, etc. can be used for adsorption dehumidification, as well as freeze-dehumidification
It mainly depends on the moisture content in your raw materials. If there is a high amount of moisture present (for example, in the form of free water), gas-liquid separation can be used to remove most of the water, followed by the use of aluminum gel or molecular sieves for further removal. Of course, whether to use molecular sieves depends on the level of moisture tolerance required; they aren’t necessary if the requirements aren’t very strict.
The moisture level in our system is normally around 200PPM; we would like to reduce it to 30PPM. However, desiccants are not sufficient to achieve this goal, as they can remove only about 5 tons of moisture per hour
The dehydration drying of methane chlorides is generally carried out using molecular sieves; you can try 3A or 4A molecular sieves. After drying, the molecular sieves can be regenerated by heating under vacuum.
