Abstract

A process and apparatus for reducing pressure of a flue gas stream including passing a pressurized flue gas stream to a vessel and through a bed of particulates in the vessel to reduce the pressure of the flue gas stream. The flue gas passes from the vessel at a lower pressure than at which it entered. The bed of particulates is disposed in the vessel between the outlet end of the inlet conduit and the inlet end of the outlet conduit. If deposits develop in the bed of particulates, the particulates can be replaced with fresh particulates to avoid excessive pressure drop. Data may be received from a stream in fluid communication with the foregoing process and apparatus.

First claim

The invention claimed is:

1. A system comprising:
(a) at least one processor;
(b) at least one memory storing computer-executable instructions; and
(c) at least one receiver configured to receive data from at least one line in fluid communication with a vessel for reducing pressure of a flue gas stream comprising: a vessel comprising a bed of particulates; an inlet gas conduit in communication with a catalyst regenerator at an inlet end and an outlet end of said inlet conduit in communication with said bed of particulates; an outlet gas conduit in communication with said bed of particulates at an inlet end; and said bed of particulates between the outlet end of the inlet conduit and the inlet end of the outlet conduit.

2. The system of claim 1 wherein the at least one receiver is further configured to receive data from a sensor on a line in fluid communication with an fluid catalytic cracking unit.

3. The system of claim 1 wherein the at least one receiver is further configured to record data on the composition and/or condition of a stream in said at least one line in fluid communication with said vessel.

4. The system of claim 1 further comprising an input/output device to collect the data.

5. The system of claim 1 wherein the processor is configured to evaluate the data.

6. The system of claim 1 wherein the processor is configured to correlate the data.

7. The system of claim 1 further comprising a transmitter to transmit a signal to the receiver.

8. The system of claim 7 wherein the signal comprises instructions.

9. The system of claim 7 wherein the signal is transmitted from the sensor on at least one line in fluid communication with an fluid catalytic cracking unit.

10. The system of claim 1 further comprising collecting data from multiple systems including said system.

11. The system of claim 1 wherein the processor is configured to generate predictive information.

12. A method for receiving data from a stream in fluid communication with a vessel for reducing pressure of a flue gas stream the method comprising:
passing a pressurized flue gas stream to a vessel;
passing the pressurized flue gas stream through a bed of particulates in the vessel to reduce the pressure of the flue gas stream;
passing the flue gas stream from the vessel at a lower pressure; and
receiving data from a sensor on a stream in communication with said vessel.

13. The method of claim 12 further comprising:
receiving data on the composition and/or condition of said stream.

14. The method of claim 12 further comprising displaying the received data.

15. The method of claim 12 further comprising transmitting the received data.

16. The method of claim 12 further comprising analyzing the received data.

17. The method of claim 12 further comprising analyzing the received data to generate at least one instruction and transmitting the at least one instruction.

18. The method of claim 12 further comprising analyzing the received data and generating predictive information.

19. The method of claim 18 wherein the predictive information comprises catalyst performance or catalyst life or both.

20. A system comprising:
(a) at least one processor;
(b) at least one memory storing computer-executable instructions; and
(c) at least one receiver configured to receive data from a sensor on a line in fluid communication with a vessel for reducing pressure of a flue gas stream comprising: a vessel comprising a bed of particulates; an inlet gas conduit in communication with a catalyst regenerator at an inlet end and an outlet end of said inlet conduit in communication with said bed of particulates; a particulate inlet in said vessel for adding particulates to said bed of particulates, said particulate inlet located in a portion of said vessel that does not receive gas flow; an outlet gas conduit in communication with said bed of particulates at an inlet end; a particulate outlet in said vessel for withdrawing particulates from said bed of particulates, said particulate outlet located in a portion of said vessel that does not receive gas flow; and said bed of particulates between the outlet end of the inlet conduit and the inlet end of the outlet conduit.
