The gas holdup in a multiphase reciprocating plate column filled with carboxymethylcellulose solutions [PDF]
Journal of the Serbian Chemical Society, 2005 Gas holdup was investigated in a gas–liquid and gas–liquid-solid reciprocating plate column (RPC) under various operation conditions. Aqueous carboxymethylcellulose (sodium salt, CMC) solutions were used as the liquid phase, the solid phase was spheres ...
