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.

Abstract: Methods and systems for recovering a hydrocarbon from fluid catalytic cracking (“FCC”) slurry and for separating a FCC slurry stream from a FCC effluent are provided. An exemplary hydrocarbon recovery method comprises the steps of: contacting a feed with a catalyst in a FCC reactor under conditions suitable to crack one or more hydrocarbons and generate a FCC effluent; separating the FCC effluent with a fractionation column to generate a product stream and a FCC slurry that collects in a lower portion of the fractionation column; drawing a first FCC slurry stream at a first temperature from a first location in the fractionation column; drawing a second FCC slurry stream at a second temperature from a second location in the fractionation column, and separating a hydrocarbon from the second FCC slurry stream, wherein the second temperature is higher than the first temperature.
