Abstract
A method and apparatus for sampling fluid catalytic cracking catalyst wherein catalyst splashing is virtually eliminated, pluggage is reduced, and the temperature and velocity of the catalyst is also reduced.
Claims7
A system for sampling catalyst during the operation of a fluid catalytic cracking unit, comprising in combination:
- a sampling line connected to a the catalytic crackign unit;
- a cyclone sampler connected to the sampling line;
- a valve contained within the sampling line for opening and closing the sampling line to allow the flow of catalyst into the cyclone sampler;
- and
- a colleciton vessel in communicaiton with the cyclone sampler, for collecting the catalyst sample, the collection vessel including a splash guard to reduce catalyst splashing as the catalyst exits an outlet of the cyclone sampler and enters the collection vessel.
2 more elements
A system for sampling catalyst from a fluid catalytic cracking unit comprising, in combination:
- a sampling line connected to the catalytic cracking unit;
- a valve for opening the closing the flow of catalyst through the sampling line;
- a cyclone sampler connected to the sampling line, capable of reducing the velocity and temperature of the catalyst flow;
- a collection vessel, in communication with the cyclone sample, for collecting the catalyst sample from an outlet of the cycle sampler;
- and
- a splash guard, attached to the collection vessel, wherein the splash guard is angled upward and inward toward the outlet of the collection vessel to reduce the catalyst splashing as the catalyst exits the cyclone sampler and enters the collection vessel.
