  • 12/2009 - 07/2012

    • Emerson Process Management
  • Project Engineer and Data Management Engineer
  • Developed of a customized inventory application for LPG gas. The data is pulled from DeltaV
    through OPC. The inventory application executes complex calculations to relate the gas mass
    with the volume in real time, considering factors that affect gases due to its nature such as
    temperature, pressure, chemical composition, etc. The process is fully automated and the
    information protected in order to avoid any manipulation. The application analyzes the data and
    informs of irregular inventory behavior that could reflect theft or gas leaks. The gas packing facility
    buys the gas by weight and sells it by volume so the application monitors the plant operation and
    suggests the time of the day when the shift performance must be evaluated in order to achieve
    the maximum efficiency.

    In charge of advanced programming of DeltaV Operate and the DeltaV Historian in order to
    provide customers reports requiring special characteristics in security, format, functionality, data
