1. A method for protecting a compressor with at least one compression stage having at least one cylinder, an inlet section configured to receive a gas wherein the inlet section comprises inlet piping and an inlet compressor valve, an outlet section configured to discharge the gas wherein the outlet section comprises outlet piping and an outlet compressor valve, sensors configured to monitor selected process property parameters at the inlet section and outlet section and generate monitored signals corresponding to the process property parameters, and a controller configured to receive the monitored signals, execute a control logic and generate signals, the control logic comprising:

  • a. a process property parameter collection component comprising;

    i. collecting data for the monitored selected process property parameters at the inlet section and outlet section using the sensors, wherein the monitored process property parameters comprise gas inlet temperature, gas inlet pressure, gas outlet temperature, gas outlet pressure, and compressor speed;

    b. an internal cylinder pressure calculation component comprising;

    i. determining an inlet internal cylinder pressure;

    ii. determining an outlet internal cylinder pressure;

    c. a temperature set point calculation and comparison component comprising;

    i. calculating a first outlet temperature set point for each cylinder;

    ii. comparing the first outlet temperature set point with the monitored gas outlet temperature for each cylinder;

    d. a signal component comprising;

    i. generating a normal operation signal if the monitored outlet temperature is consistent with the first outlet temperature set point.ii. generating a first warning signal if the monitored outlet temperature is inconsistent with the first outlet temperature set point.
