Question: (DMTO) Olefin separation unit: The common drying methods mainly include: (1) Air or nitrogen with normal temperature and low dew point for drying ； (2) Hot air circulation drying ； (3) Thermal nitrogen cycle drying. Note: The answers will be released automatically in two days!
There are three methods: normal temperature low dew point (nitrogen) drying, hot nitrogen circulation drying, and solvent circulation absorption drying.
(1) Air or nitrogen drying at room temperature with low dew point； (2) Hot air circulation drying ； (3) Thermal nitrogen cycle drying.
1. Vacuum drying 2. Boiling drying 3. Freeze drying 4. Spray drying 5. Microwave drying
(1) Mechanical dehydration method (2) Heating and drying method (3) Chemical dehumidification method
