SHELL U.K. R2R FCCU REVAMP Project STANLOW Complex Elsmere Port In 1993 Shell UK awarded Flexider a contract worth 1.000.000,00USD to supply the new expansion joints for the major revamp of the FCCU in STANLOW Complex-Elsmere Port.

The total work scope included 9 expansion joints of significant size and incorporating the latest e.j. design concepts: § 1 off Spent Cat. Standpipe ND 1100 § 1 off Regen. Cat. Standipipe ND 1250 § 2 off Recirc. Cat. Standpipe ND 900 § 1 off Regen. Overhead line § 1 off Double Gimbal and ND 1850 § 1 off Hinged ND 1850 § 4 off Secondary Separator ND 200 § 1 off Third stage separator ND 1500 Cold shell construction was used for the process expansion joints, meanwhile, all of them were equipped with ply testable bellows for 100% redunancy.

For the first time in the FCC applications bellows sections of the expansion joints were provided of an electrical tracing system to maintain bellows surface temperature above dew point during start-up and shut-down operations.

Both external insulation of these bellows and adjacent piping on the cold side required a lot of design attention because of concern about keeping bellows area hot enough to avoid condensation.

Parallely, same attention was given to optimize the interaction of the various insulation layers: a. Inside blanketing b. Outside blanketing c. Insulation blanketing for the heating sandwich provided to avoid dispersions.

Vis a vis of the type of equipment, it was decided by Flexider to carry out a performance test to verify the heating capacity of the trace heating sandwich and temperature distribution.

To carry out this test, a burner was hired with relevant gas tank.

One end of the joint was insulated, partially blinded and the burner connected at the inlet side to blow hot air at 720°C. Test was divided in two phases: one of 18 hours and the second of 27.

This test worked out a profitable experience to Flexider and built positive bases to the development of a simpler heating system though with same capability.
