Abstract
A plant or refinery may include equipment such as condensers, regenerators, distillation columns, pumps, slide valves, or the like. Different operating methods may impact deterioration in equipment condition, thereby prolonging equipment life, extending production operating time, or providing other benefits. Mechanical or digital sensors may be used for monitoring equipment to determine whether problems are developing. Specifically, sensors may be used in conjunction with one or more system components to predict and detect slide valve sticking. A shielded, tube skin thermocouple assembly may provide a temperature profile for a slide valve. Tomography may be used to image a slide valve. An operating condition of the plant or refinery may be adjusted to prolong equipment life or avoid equipment failure.
