Upstream Process/Facilities Consulting Engineer.

Project Lead Kearl FEED Flare verification for Imperial Oil Limited, Canada. I was the lead consulting engineer in Performing a FEED Relief and Flare design verification on behalf of Imperial Oil Ltd. In this study we verified the Identification of overpressure and depressuring scenarios that resulted in significant releases to the proposed relief header and flare systems. We designed the preliminary routing of relief headers based on proposed locations of equipment; pipe racks flare stacks and the available plot plan.

My team determined the proper slope of the relief header, determined if the correct sizes were used for the verified relief rates and also verified material and relief temperatures expected. I also performed an Acoustically Induced Vibration (AIV) screening study on the header piping to identify areas of excess vibrations that can adversely harm the flare.

I verified the required tip diameter based on exit velocity limitations, verified the required flare stack height boom length and horizontal separation from critical exposure based on radiation. We performed a flare radiation analysis to ensure that the radiation limits are adhered to. We also verified dispersions for flame out scenarios including H2S. We verified that the required knockout drums provided adequate liquid retention time and proper droplet separation.

Project Lead: Chevron Cape Town (SA) Flare Upgrade project Provided technical lead role in the review of the existing Chevron Cape Town facility flare network (with 150 relief valves), using Flarenet, and associated relief valve data sheets (design basis) to verify the completeness of the current relief system. Identified Global overpressure scenarios for all the current pressure relief valves. Then conducted the same analysis on 60 atmospheric valves identified as requiring to be tied-in to the existing a closed disposal system.

Used the relief rate obtained to run the Flarenet model of the facility’s flare. Identified sources with excessive back pressure problems. Performed a QRA to take into consideration the mitigations available for each process. Finally performed a Front End Engineering and Design study on the addition of these new atmospheric valves into the existing flare network.

Technical Lead Irving Oil Limited Fortify Project Flare Study. Performed a flare study to capture how the relief load changes from the Fortify project will affect the existing flare system. The first part of the project was to perform a pressure relief system analysis on all equipment in the Visbreaker unit. This included but was not limited to identifying potential case of overpressure, quantifying relief rates and evaluate adequacy of relief valves. The second part of the project included performing a flare header hydraulic study, Flare quantitative risk analysis and mitigation analysis. This part of the study included providing back pressure information, the knock out drum sizing and flare radiation results for the new configuration.

Technical Lead ExxonMobil Erha Facility Pressure safety revalidation Lead a team in performing a revalidation of the pressure relief system of the ExxonMobil Erha offshore facility. This study was based on a change in throughput to the facility and addition of new valves to the relief system. For the new relief valves (20) overpressure scenarios were identified, the required relief rates were calculated and sizing was done. For all the other existing relief valves (58) all the relief rates were recalculated and sizing was done to ensure that they still adequately protect the respective equipment. Flare Hydraulics analysis, new backpressures, knockout drum sizing and radiation analysis were then performed to ensure that they still were within the specified ExxonMobil requirement.
