Front-end design engineering. Require preparing documentation for Process Design Basis (PDBs). Includes quotes, inspection reports, review mechanical drawings, review maintenance inspections, and markup P&IDs. Also include designing equipment for mechanical integrity, and sizing equipment properly. Calculations through excel, aspen, or pipe-flo. Twic Card holder

Experience in management of safety compliance, capacity expansion/process improvement, plant trials, and full-scale production projects. Also work with production to improve cycle times and gather asset effectiveness data for specific units. Tasks also require preparing documentation and leading PHAs as well as Environmental Health and Safety reviews. Job requirements also require implementing MOCs for any changes as well as managing the MOC and ensuring it is thorough and complete in a timely manner. This includes conducting field walk through PSSRs and operational training. Documents including design drawings, updated P&IDs, Operational procedures, PFDs and or PowerPoint presentations were utilized for operational training and PSSRs. Startup overview and assistance with operations for all projects were provided. This included trouble shooting for process optimization.

Provide technical assistance with PSM regulated process for 5 capital projects.Tasks includeScaling up Material balances, Air emission calculations, Energy Balances, PFDs, P&IDs, Creating detailed operation procedures, Safety reviews, Completion of Process Hazard Analysis, HAZOPs, consequences of deviation, and technical risk assessment, Oversee Process in pilot plant, and Provide technical assistance and troubleshooting to the process.

Ran a project that used process control to cool a fuel cell stack.Analyzed data with Microsoft Excel, PowerPoint, and Minitab Validated results through heat transfer equations and simulation software.
