Raman-Based Process Analytics for Paraxylene Separation

제품 설명

Raman-Based Process Analytics for Paraxylene Separation In PX production, process decisions depend on accurate information about the composition of C8 aromatic streams. The challenge is timing. When analytical results come from periodic laboratory chromatography, the process may already have changed by the time the result reaches the production team. For adsorption separation, where concentration profiles evolve continuously, this delay can limit process optimization. JINSP
