METAL CYLINDER SAMPLING PROCEDURE #0007
PROCEDURE
Step
Action
1 Remove the VCO caps, install the cylinder with the dip tube up and block in the bypass valve.
2 Open the bottom valves first allowing the cylinder to pressure.
3 Next open the top valves slowly, allowing the sample to flow through the cylinder back to the process.
4 After a few minutes the cylinder should be full and all valves should be blocked starting with the top valves first, (dip tube end)
followed by the bottom valves.
5 After all valves are blocked remove the cylinder and replace the VCO caps and open the sample bypass valve.
6 Return the cylinder to the lab for analysis.
7 Vent unused cylinder contents to the vent header after analysis is complete and place cylinder on nitrogen purge under hood.
