Problems with the C5 separation unit
Thread Content
What is the role of adding sodium nitrite in fixed amounts and at regular intervals daily into the extraction solvent (N,N-dimethylformamide) within the extraction module of the C5 separation unit in the extraction process?
One of its functions is to remove oxygen from the device
Sodium nitrite reacts preferentially with formic acid to form insoluble formate complexes, while the trace amount of oxygen present in the system accelerates the polymerization of the dienes in C5 hydrocarbons, resulting in diene polymers (coke)
