While employees at BASF were using high temperature steam to clean an operational T-2265 Halogen Purge Destruct Tower, the internal ETFE liner suddenly popped up, compromising the integrity of the liner in four sections of the tower. The steam was a higher temperature than the ETFE liner was rated to withstand. This liner, installed for corrosion protection against chlorine service in BASF’s MDI synthesis unit, was originally manufactured by RMB Products and was in operation for 17 continuous years.
The failed liner was removed on-site at BASF and the four sections were then sent to RMB. Once the pieces arrived, our production team rotationally lined them with new ETFE, applied paint on the external surfaces, and shipped them back within a four-day turnaround time.
Meeting this quick deadline gave the BASF employees the opportunity to re-install the equipment without having any production downtime. This new liner is expected to exceed 17 years of operation.
