Carmagen Engineering, In. 4 West Main Street Rokaway, NJ 07866 Telephone: 973-627-4455 Fax: 973-627-3133 www.armagen.om Mehanial Engineering Experiene Related to FCCU and Other Fluidized Solids-Type Units The following is a partial list of work that Carmagen's mehanial engineers have done with respet to the mehanial engineering aspets of FCCUs and other fluidized solids-type units. This work has been done either while employed at Carmagen or before joining the ompany. Work Done By Carmagen Team leader and tehnial onsultant for a major inident investigation involving failure of refratory lined transfer-line piping system that aused an unsheduled shutdown of a FCCU loated in the US Gulf Coast. Team leader for a major FCCU unit reliability study for a US Gulf Coast refinery. Problems identified inluded piping vibration and high maintenane ost. Developed tehnial speifiations for several grid, ylone, and/or plenum hamber replaement projets. Also provided bid onditioning support, engineering quality ontrol of the ontrator and supplier s work, and turnaround assistane. Performed study of a regenerator grid that enabled a refinery to inrease operating flexibility in running their FCC while still maintaining reliability. The study onsisted of a reep-life evaluation of the regenerator grid based on past operations and aounting for various potential ombinations of operating temperature and pressure differential aross the grid. In the study we used finite element analysis to determine the grid stresses as a funtion of the differential pressure aross the grid. We then used the remaining life provisions of API 530 to produe a set of urves that provided the remaining life of the grid for a given operating differential pressure and temperature above the grid. Performed piping flexibility analysis of FCCU regenerated atalyst transfer line to determine the benefits of replaing the existing line that had experiened hot spots. The projet involved using a larger diameter pipe and thiker refratory system. The piping analysis showed that the replaement pipe redued the probability of the suspeted ause of the hot spots while maintaining aeptable system stresses and equipment loads. Conduted a piping stress analysis to revamp high temperature, refratory lined, Flexioker transfer lines. The analyses inluded alulation of the metal temperatures for a variety of operating ases, alulation and evaluation of the pipe stresses and the loads on onneted equipment.
Performed numerous engineering audits of piping stress analyses that were done by ontrators on major apital projets. Developed tehnial speifiation for performing piping stress analyses for use on apital projets. Work Done Before Joining Carmagen Worked on over 50 FCCUs in grass root and revamps in the mehanial design of reators, regenerators, and piping layout and stress analysis for major transfer lines, feed piping, and aeration piping. This also inluded the materials seletion, speifiation, and refratory systems design (done for Exxon, CPC, BP Spain, Lagoven, Sakai, Mobil, Caltex, et.). Conduted Engineering Audits on approximately 7 different FCCUs to identify opportunities to improve profitability through improved reliability and redued maintenane. Audits of mehanial hardware typially inlude major vessels, piping, slide valves, and refratory systems to identify opportunities to improve individual omponent performane as well as the overall unit profitability. Overall piping experiene inludes layout, materials speifiation, refratory lined systems, stress analysis, aousti noise (vibration) attenuation, surge, and other forms of vibration attenuation for a variety of systems in virtually all types of refining units. Led the overall mehanial design for the revamp of the Caltex Model IV FCCU in Australia inluding the design and speifiation of major transfer lines, feed piping, and aeration piping. Provided tehnial onsulting for a bulged setion of refratory lined pipe in a FCCU transfer line. Provided field re-engineering for poorly designed piping systems in fluid solids units to aommodate thermal expansion (at Pemex, Synrude, Beniia, Ingolstadt). Eliminated aoustially indued vibration in a large flue gas line in a fluid solids unit. Redesigned a flue gas line to eliminate vibrations indued by surge fores in the fluid bed. Eliminated small piping vibration failures by redesigning to eliminate raking aused by pressure pulses at a Hydrogen ompressor. Developed designs for large transfer lines to prevent raking of stainless steel omponents (several FLEXICRACKING Units). Investigated ause of failure and developed fix to prevent piping failures around Hydrogen reformer furnaes (Lagoven, Toa Nagoya). 2
During start-up of fluid solids units, developed field fixes to eliminate piping vibration and thermal expansion problems (Beniia, Pemex, Synrude). Partiipated in a root ause failure analysis of an expansion joint in a FCCU transfer line standpipe. Partiipated in a team effort as a tehnial speialist to identify the ause of ontinuing failures of an expansion joint in a feed riser. Performed a piping flexibility analysis of a FCCU flue gas piping system that inluded a turbine expander and expansion joints. The analysis model had piping in the range of 72 to 108 in diameter. The purpose of the analysis was to design onstant effort pipe supports to inrease the reliability of the turbine expander. Performed piping flexibility analysis of a 96 diameter lined FCCU spent atalyst piping system as part of redesign of hinged rotation joints to improve their reliability. The existing rotation joints ontained angled dis elements instead of bellows. This did not permit adequate inspetion of the rotation joints for raking at turnarounds. The redesigned hinged rotation joints were inluded as part of the piping system analysis to determine the required rotation at eah joint. 3
