Claim Text:
1. An industrial packaging plant, comprising: a system for filling a second receptacle with carbon nanotubes from a first receptacle, said system comprising the first and second receptacles and a means of coupling the first and second receptacles comprising a double-valve device comprising a first valve, of the butterfly valve type, and a second valve, of the butterfly valve type, said first valve removably coupled to said first receptacle and said second valve removably coupled to said second receptacle, each of the valves closing independently and tightly upon coupling to said first and second receptacles, wherein said first valve and said second valve are openable only when coupled together and said valves operate in tandem when coupled and being opened, a reactor in which carbon nanotubes (CNTs) are formed, a cooler connected to the reactor, an airlock to recover the carbon nanotubes from the reactor and be inerted, a pneumatic conveyor connecting the airlock to a vacuum chamber with air filtration, an in-line screen positioned after the vacuum chamber to separate out large particles, a storage hopper coupled to an outlet of the in-line screen, a metering valve positioned between the storage hopper and the double-valve device, and an air filter for filtering air conveyed with the carbon nanotubes.
