High Purity CO2 Gas
High Purity CO2 Gas
(OP)
Flow Rate : 500~ 1000kg/hr (total Gas Flow)
Composition
CO2 :99.993 vol.%
O2 : 25ppm
N2 : 35ppm
H2O : 1.5ppm
others : 8.5ppm (as unknown)
Question:
We will intend to increase CO2 Contents up to 99.999%
First We want to remove N2 and O2 from CO2 Gas
comment Device or method ? please

RE: High Purity CO2 Gas
I discussed this with UOP. But they answered Mole sieves is not the solution.
I am thinking How about Membrane...anyway thank you again..
RE: High Purity CO2 Gas
Membranes cannot help at these purity levels - they work okay for coarser separations.
Low temp extractive distillation (say with chilled propane or chilled butane) may be possible, but operating expenses will go through the roof.
