Question: (DMTO) Olefin separation unit: How many methods are there for storing ethylene? (1) Storage by pressurization. Ethylene spheres are used to store liquid ethylene, with a storage pressure generally ranging from 1.9 MPa to 2.4 MPa and a storage temperature ranging from -30°C to -20°C. (2) Storage by low-temperature method. Low-temperature storage involves storing and transporting at near-atmospheric pressure (operating pressure of 102–112 kPa) and slightly below the boiling point (boiling point at atmospheric pressure: -103.71°C). Low-temperature ethylene storage tanks have a large capacity, with each tank being able to store from several thousand cubic meters to tens of thousands of cubic meters. Note: The answer will be announced automatically in two days!

Store in a cool, well-ventilated warehouse. Keep away from sources of fire and heat. The storage temperature should not exceed 30°C. It should be stored separately from oxidizers and halogens; mixed storage is strictly prohibited. Use explosion-proof lighting and ventilation facilities. The use of mechanical equipment and tools that can generate sparks is prohibited. The storage area should be equipped with emergency equipment for handling leaks.
