Less obvious, however, are the importance of interacting intelligently with the equipment vendor about a host of other tray- and column-related details, and of aiming for proper engineering coordination between various parties involved during column design and fabrication to ensure a smooth erection and startup. **
Among the key parameters and accessories during specification are ...
