Abstract:

A combination of differently sized structured packings in the wash zone of distillation towers is provides advantages at high vapor rates. The use of a large crimp structured packing below a smaller crimp size structured packing is advantageous for vacuum crude unit service where fouling resistance is desirable and liquid entrainment into the wash zone is a problem at high vapor rates. The tower may be operated at high vapor flux rates or C 0.4 ft/sec or higher (0.12 m/sec). An unexpected characteristic of the combinations is that the entrainment increases only slowly with increasing vapor flux rate up to Cs values of at least 0.55 ft/sec (0.17 m.sec), as compared to other packings such as random packing, grid packing and combinations of grid packing with structured packing which allow entrainment to increase sharply at high vapor rates.

Abstract:

System to detect coking in at least one component of refinery equipment is provided. The system includes a fiber optic assembly having at least one optical fiber operably coupled with the component, the fiber optic assembly further including a light source to transmit light having a known parameter through the optical fiber and a receiver to receive the light from the optical fiber, and a processor in communication with the fiber optic assembly to identify a shift in the parameter received by the receiver, the shift corresponding to an operating characteristic of the component. Method also provided for detecting coking using the system to detect coking disclosed herein.
