As part of a student project we are looking to move a solid powder (CO2) from one container at 1 atm to another container at 6 atm. Are there devices that move solids while creating a seal so as to not lose pressure?
I'll not solve your problem because you're supposed to do it thinking freely.
But I have two basic principles in mind. One is to use a classic pressurization chamber to move material in batches. Another one is to use air and move the powder using levigation. To keep the container pressurized, just balance the gas output.
If the <...CO2...solid powder...> were simply warmed up, that would save moving it <...from one container...to another...> and <...6 atm...> would be achieved easily.
