* Vapor Control: MTBE is highly volatile and readily evaporates into the atmosphere. The domed lid helps to contain these vapors, reducing the risk of emissions and potential environmental pollution.
* Fire Prevention: MTBE is highly flammable. The domed lid prevents the accumulation of flammable vapors in the tank, reducing the risk of fire or explosion.
* Safety: The lid helps prevent accidental spills and leaks, as well as the entry of contaminants into the tank.
* Preventing Oxidation: MTBE is susceptible to oxidation, which can lead to the formation of peroxides, which are unstable and potentially explosive. The domed lid helps to limit exposure to air and thus slow down the oxidation process.
In addition to the domed lid, other safety measures are also implemented for MTBE storage, such as:
* Pressure relief valves: These release excess pressure inside the tank to prevent explosions.
* Emergency shut-off valves: These allow for rapid isolation of the tank in case of an emergency.
* Leak detection systems: These monitor for any leaks and provide an early warning system.
The domed lid is a crucial safety feature for MTBE storage, ensuring safe handling and reducing the risk of environmental damage and accidents.
