    Study Notes

    Industrial Plant Utilities

    • Utilities are supplementary processes in industrial plants, providing power, steam, and water.
    • Common energy sources include oil, gas, coal, and nuclear energy.
    • Decreasing availability of some energy sources necessitates a shift to alternative energy sources.

    Power Requirements in Production

    • Power for production industries is chiefly electricity, with other sources including steam engines, internal combustion engines, and hydraulic turbines.

    Power Generation Decisions

    • Design engineers must decide between purchasing power or generating their own (if both options are available, to achieve continuous operation).

    Steam Usage

    • The amount of steam used varies based on thermal and mechanical needs.
    • Steam should be generated from the cheapest fuel source available.
