• PROFILE

  • Hello, I am Jeremy Castagno

    Chemical & Process Control Engineer

    I develop and use technology to solve complex problems in the automation industry. My work involves analyzing physical systems and developing control strategies to regulate key control variables. I am familiar with many control systems, safety systems, and general control technology. I am proficient in more than a dozen programming languages and am an active learner

  • Blending Control System

    As the project control system engineer I was tasked with helping design and implement a major overhaul of the gasoline blending system. This involved the complete upgrade of the basic control system (BCS) and the installation and programming of an advanced process control (APC) layer using online analyzers.

    Heater Safety Systems

    Safety Interlock Systems (SIS) play a vital role in ensuring the operability and safety of process units. I lead the SIS design and verification through factory acceptance tests (FAT) and site acceptance tests (SAT) for 4 process heaters. The FAT involves rigorous testing through simulation to prove logic in the SIS. The SAT connects the SIS to the field instrumentation and performs a full functionality test.

    Gasoline Model Analysis

    As an intern I was assigned to perform a full analysis of the accuracy of a major energy corporations gasoline blend models. These models are used to predict the properties of gasoline, and if accurate, can greatly increase refinery revenue through optimal planning. I gathered thousands of gasoline blend data and performed a full statistical engineering analysis. One model was identified to be poor for which I modified increasing its accuracy by over 50%.

    Model Predictive Contol

    Unmanned Ariel Vehicles (UAV's/Drones) have become a mainstream interest in present time. Our research at BYU focused on Moving Horizon Parameter Estimation used to provide detailed control of UAV capturing system. In this system a UAV low on fuel is to be recovered by a "Mothership" with a cabling system. This delicate process is controlled based on detailed models whose parameters are determined using advanced estimation algorithms.
