CHANGES TO MAINTAIN FCCU CONVERSION AM-02-44 by Jacqueline D. McKinney Consultant Six Sigma Conoco, Inc. Lake Charles, Louisiana and William D. Henning Consultant Refining Technology Group Conoco Inc. Ponca City, Oklahoma and Peter Andrews FCC & Refinery Consultant Andrews FCC Consulting Houston, Texas and Bruce Dodds Senior Project Manager International Alliance Group Houston, Texas Presented at the 2002 NPRA ANNUAL MEETING March 17-19, 2002 San Antonio, Texas AM-02-44 Abstract Conoco Inc. successfully implemented a major and innovative project to address catalyst circulation and improve yields from the Orthoflow F fluid catalytic cracking (FCC) unit located at their Lake Charles, Louisiana refinery. A key component of the project was the addition of an external spent catalyst stripper to reduce the load on the existing internal spent catalyst stripper. The project also replaced the regenerated catalyst plug valve and regenerated catalyst J-bend standpipe with a cold wall wye section and UOP’s elevated Optimix feed distribution system. The project improved FCC catalyst circulation, resulted in increased conversion and improved yield selectivity, while also providing the flexibility for processing of heavy aromatic feedstock. The project’s success can be attributed to advanced planning and to the team approach taken by Conoco, International Alliance Group (IAG), Andrews FCC Consulting and UOP. Approximately two and one half years prior to the actual shutdown, Conoco assembled a team of FCC specialists to discuss operational and reliability objectives and apply knowledge learned from previous FCC projects executed at Conoco’s Ponca City and Denver refineries. IAG provided single-point responsibility for meeting the goals of the project through turnkey implementation of technology, engineering, procurement and construction. The team approach not only resulted in a successful revamp, it also allowed Conoco to improve FCC operations and improve unit profitability in the period leading up to the turnaround. |

Innovative Technology Meets Processing and Environmental Goals: Flying J Commissions New MSCC and TSS Vincent J. Memmott General Manager For Refining, Processing and Engineering Flying J Refinery Bruce Dodds International Alliance Group Presented at NPRA 2003 National Meeting March 23-25, 2003 Marriott Rivercenter Hotel San Antonio, TX Abstract Big West Oil LLC’s Flying J refinery is a supplier of transportation fuels and waxy feedstocks in the Intermountain West region and throughout the United States. In an effort to more efficiently utilize the available crude mix, Flying J recently started up a grassroots MSCC unit. With the installation of the catalytic cracking unit, Flying J was required to install a flue gas cleaning technology that could meet EPA NSPS regulations. The technology chosen by Flying J for the removal of particulate matter from the MSCC flue gas was the UOPTM Third Stage Separator (TSS). The installation of the UOP TSS in a strictly environmental capacity is a departure from the traditional role of the TSS as protection for a power recovery expander. Flying J moved forward with the project recognizing that newly developed technology was being commercialized. The MSCC performance has been very satisfactory and the TSS has succeeded in meeting, and exceeding, EPA requirements for particulate emissions from the MSCC unit. The decreased costs associated with installing the TSS, when compared with other flue gas cleaning technology, and the improved yields from the MSCC have resulted in an improved refinery position of $1.60-$1.70 per barrel of crude charge. The close cooperation between Flying J, the process licensor UOP, and IAG who managed the project, contributed to a cost effective project with a simple payout of 25 months. |

Execution Strategy For Fast-Track Revamp Projects
by: Harvey McQuiston International Alliance Group (IAG) Presented at AIChE 2003 Spring Meeting April 3, 2003 Retrofitting / Revamping Session Ernest N. Morial Convention Center New Orleans, Louisiana Abstract Project execution by traditional methods requires a degree of advanced planning and significant front-end engineering, resulting in a 2-year plus project schedule. In today's economic climate, the cycle of good refining margins seldom coincides with the timing required to meet unit turnaround, which is relatively inflexible. When capital improvement projects eventually get approved funding, there is often too little time to execute the project without using a fast-track approach. Furthermore, the fast-track approach can accelerate the refiner's rate of return as well as get the refiner to market earlier with improved unit performance as new technologies emerge. This paper outlines a proven fast-track approach to revamp projects that still retains the risk minimizing attributes of the conventional approach. Examples of three recent fast-track revamp projects are given. |

EFFECTIVE FCC REVAMP MANAGEMENT LEADS TO SUBSTANTIAL BENEFITS by Bill Miller, Jeff Warmann, and Alan Copeland Williams Refining, LLC. Memphis, Tennessee and Terry Stewart International Alliance Group Houston, Texas Revised 3/13/00 Presented at the 2000 NPRA ANNUAL MEETING March 26-28, 2000 San Antonio, Texas AM-00-24 Abstract Williams Refining, LLC has successfully implemented a major revamp to increase the capacity and yield performance of its fluid catalytic cracking (FCC) unit located in Memphis, Tennessee. The entire project was accomplished in less than one calendar year, from start of engineering to completion of the turnaround. Project management, procurement, engineering and construction was provided by International Alliance Group (IAG) of Houston, Texas as general contractor. The FCC revamp design utilized the latest technology from UOP LLC. The success of this project was a direct result of the effective team approach between Williams, IAG and UOP. |
