Welcome to Burgess Pipeline Services, your premier choice for all-inclusive odorant transfer solutions. Our expertise lies in the secure and efficient transfer of odorants for natural gas operations, with an unwavering commitment to safety and reliability.
Odorant transfer can release strong vapor and should follow the site’s approved procedures, the current safety data sheet, applicable equipment instructions, and qualified personnel requirements. Burgess Pipeline Services provides operational support and documentation, not legal advice.
Connecting an Odorant Cylinder to Your Operations
Receive the cylinder and assess for any damage.
Ensure the valves are closed. If not, close the valves.
Remove the shipping plugs slowly from the valves to ensure there is no pressure under the plug.
Install the proper fittings for hose into the cylinder valves.
Install the pressure hose onto the cylinder valve marked ‘Vapor’.
Install the liquid hose onto the cylinder valve marked ‘Liquid’.
Connect the liquid valve of the cylinder to the corresponding discharge points and keep it closed.
Pressure with regulated inert gas (Nitrogen is commonly used) to desired PSI through the Vapor hose and check for leaks.
Open the cylinder ‘Vapor’ valve and check all fittings for leaks.
Check that the receiving vessel’s pressure is lower than the pressure you put in the cylinder.
Open the cylinder liquid valve and liquid odorant will discharge into the connected vessel.
Do not exceed the receiving container's marked or operator-approved maximum permitted fill level.
Disconnecting a Cylinder from Your Operations
Cylinders must be returned empty of liquid: once empty, close the ‘Vapor’ cylinder valve.
Allow vapor to blow through the liquid hose to purge the hose of any residual liquid (the cylinder and your vessel should equalize in pressure).
When liquid hose is purged, close the liquid valve.
Carefully remove the hoses from the vapor valve and the liquid valve.
Spray hose ends and fittings with a neutralizing agent to reduce residual odor.
Return or depressurize the cylinder only as directed by the cylinder supplier and the applicable operator-approved procedure.
Carefully remove the fittings from the vapor and liquid valves.
Install shipping plugs in the liquid and vapor valves and prepare the cylinder for transport.
Transportation classification, packaging, closure, marking, labeling, shipping papers, residual-material status, and emergency information must be determined for the actual odorant and container using current shipping documents, supplier instructions, and applicable requirements. Do not assume every odorant or residue has the same hazard class.
At Burgess Pipeline Services, we provide project-specific odorant transfer planning, field coordination, and documentation within an agreed scope. The responsible operator must determine applicable requirements and approve the work procedures. Contact us to discuss support for your natural gas operations.
