Lindsey is a process engineer with deep expertise in pressure relief system design, including sizing, selection, and installation calculations to ensure compliance with applicable industry standards. Â She has utilized Aspen Flare System Analyzer to model PRV mitigations and performed pressure/vacuum vent calculations for clients across a range of industries. Â Recognized for her knowledge of relief systems, Lindsey serves as an instructor for the API-U preferred Pressure Relieving Systems course, covering API 520 and 521.
At Equity Engineering, Lindsey has applied risk-based inspection (RBI) methodologies to analyze and adjust PRD inspection intervals and has worked on tube vibration analyses and tube rupture credibility assessments for heat exchangers. Â She is proficient in HYSYS and Symmetry for process simulation and fluid modeling and serves as a project manager for process-related engagements, blending technical depth with client coordination and project execution. Â She is also an active contributor to the Equity Engineering Practices, with a particular focus on cooling tower standards.
Prior to joining Equity Engineering, Lindsey built a strong foundation as a process engineer on design projects spanning the chemicals, refining, and renewables industries. Â Her project experience includes a cooling water system redesign to resolve low-flow conditions, a distillation tower upgrade to support expanding semiconductor fabrication demand, a hydrogen compressor installation, and multiple tank and instrumentation upgrades within the coker unit of a major Midwest refinery, driven by reliability issues requiring shutdown. Â Across these projects, she developed demo and construction P&IDs, performed piping hydraulic calculations, and determined equipment, utility, and instrumentation requirements. Â She also created process simulations and heat and material balances using Aspen HYSYS and AFT Fathom to satisfy flow rate and line sizing requirements.
