Loading of chemical products onto ships
Thread Content
I would like to ask what precautions should be taken when loading butadiene onto a ship, such as flow rate, temperature, etc. Does anyone have a technical guide that they could share?
1. Styrene cannot be exposed to light or air directly, as light causes styrene to polymerize, and exposure to air leads to gradual polymerization and oxidation reactions. 2. Styrene is flammable and undergoes vigorous polymerization under certain conditions. A 15 ppm amount of the polymerization inhibitor TBC is generally added during storage and transportation. TBC’s Chinese name is tert-butylhydroquinone. 3. The antipolymerization effect of TBC requires a certain level of dissolved oxygen; therefore, the styrene storage tanks are designed as dome-shaped tanks. When the ambient temperature is below 25°C, cooling measures should be taken; for long-term storage, pump-driven circulation or internal cooling tubes should be used. Styrene should not come into contact with materials such as rubber and copper. Styrene changes color when in contact with copper.
