2x Texas Towers cleaned in 5 shifts (Down from 24 shifts)
Safety, speed and cleanliness were deemed the most important factors by the 230,00bpd (crude) and 17,000bpd (lubricant) French refinery.
The two V.C.F.E. (Texas Tower) combine feed/effluent exchangers were last cleaned on the Shell and Tube side in 2001 when it took 24 shifts to clean each VCFE Texas Tower, using traditional high pressure water jetting guns and lances but was deemed dangerous, slow and very inefficient with very little improvement in performance.
