A method, apparatus and system for obtaining a sample of a fluid solids, such as a coke and hydrocarbon mixture, from a fluid solids process is provided. A sample vessel is provided that contains a first end, a second end, an aperture in the first end and an interior cavity. A cooling device can be provided for cooling material in the interior cavity of the sampling vessel. In operation, fluid solids can be routed through the aperture and collected in the interior cavity. The collected sample material can then be cooled by the cooling device and used for testing.

1. A method of obtaining a sample comprising hydrocarbon and hot fluid solids from a fluid solids process, the method comprising: providing a sample vessel having an interior cavity;collecting the sample comprising hydrocarbon and hot fluid solids in the interior cavity of the sample vessel;cooling the sample comprising hydrocarbon and hot fluid solids while the sample is retained in the interior cavity of the sample vessel to reduce thermal cracking of the hydrocarbon present in the sample. 2. The method of claim 1 wherein the sample comprising hydrocarbon and hot fluid solids is cooled in the interior cavity of the sample vessel by providing a cooling coil running through the interior cavity and circulating cooling fluid through the cooling coil. 3. The method of claim 2 further comprising venting gas from the interior cavity of the sample vessel while the sample comprising hydrocarbon and hot fluid solids is being collected in the interior cavity. 4. The method of claim 3 wherein the fluid solids is a coke and the fluids solid process is a fluid coking process. 5. The method of claim 1 wherein a lid is provided on the sample vessel to allow access to the interior cavity. 6. An apparatus for obtaining a sample of fluid solids from a fluid solids process, the apparatus comprising: a sample vessel having an interior cavity, a first end, a second end, an aperture in the first end of the sample vessel leading into the interior cavity, and a cooling device comprising a cooling coil for cooling the interior cavity; andan incoming conduit connectable to a source of the sample and to the aperture in the first end of the sample vessel to route the sample from the source to the interior cavity for cooling. 7. The apparatus of claim 6 wherein the cooling coil takes a circuitous path through the interior cavity. 8. The apparatus of claim 6 further comprising a vent conduit in fluid communication with the interior cavity. 9. The apparatus of claim 8 further comprising a filter inline with the vent conduit to prevent substantial amounts of the fluid solids to pass by the filter. 10. The apparatus of claim 6 further comprising a thermometer passing into the interior cavity. 11. The apparatus of claim 6, wherein the second end of the apparatus comprises a removable lid to provide access to the interior cavity. 12. The apparatus of claim 11 further comprising a vent conduit provided in the lid and in fluid communication with the interior cavity. 13. The apparatus of claim 11 further comprising a thermometer passing through the lid and into the interior cavity. 14. A system for obtaining a sample comprising hydrocarbon and hot fluid solids from a fluid solids process, the system comprising: a sample vessel having an interior cavity, an aperture leading into the interior cavity, a cooling device for cooling the sample comprising hydrocarbon and hot fluid solids when it is contained in the interior cavity to reduce thermal cracking of the hydrocarbon present in the sample, and a vent conduit in fluid communication with the interior cavity;an incoming conduit connectable to the sample vessel to route the sample from the fluid solids process to the aperture of the sampling vessel;a gas conduit connectable to the vent conduit of the sample vessel for routing gases away from the sampling vessel; anda first valve to control the flow of the sample in the incoming conduit, a second valve to control the flow of the sample into the sampling vessel and a third valve to control the flow of gas from the sample vessel through the gas conduit. 15. The system of claim 14 wherein the cooling device is a cooling coil that takes a circuitous path through the interior cavity. 16. The system of claim 14 further comprising a filter inline with the vent conduit. 17. The system of claim 14 further comprising a thermometer passing into the interior cavity of the sample vessel. 18. The system of claim 14 further comprising an eductor inline with the gas conduit. 19. The system of claim 14 wherein the sample vessel can be disconnected from the incoming conduit and the gas conduit so that the sample vessel can be removed from the system.
