Decommissioning and Deodorization

When a piece of odorant equipment meets the end of its useful life it must be decommissioned and deodorized by trained technicians.

Retired odorization equipment will still retain a residual odor. Decommissioning and deodorization must be completed by trained personnel to avoid the release of this odor into the environment. Old odorant equipment cannot be simply placed into a landfill or recycled without treatment.

Tansley technicians will come to your site and decommission your old odorant equipment then prepare it for transportation to one of our locations. At the Tansley location it will be deodorized, rendered inoperable and sent for recycling where it becomes rebar.

If our customers require odorant to be transported from one site to another, we can do that too. We have moved from a few gallons to thousands of gallons for our customers. As part of this service we can test and filter the odorant also.

  • Our technicians are highly skilled, well trained and experienced
  • Our equipment is advanced and regularly undergoes a thorough maintenance schedule


When odorant is first introduced into steel pipelines the sulphur in the odorant will react with the steel pipe to create a layer on the inside of the pipe (pickle). This means that when a pipeline begins operating the odorant injected into the pipeline will be used up in the pickling process and will not reach the end of the pipe; resulting in unodorized gas coming out the end of the pipeline.

Odorant conditioning (pickling) is required for new or reserviced pipelines and consists of adding controlled amounts of additional odorant to account for the odorant loss due to pickling.

Working with a world class odorant conditioning (pickling) expert, Tansley provides a full service odorant pickling solution to our customers.

We can provide engineering, planning, equipment, operations and post pickling reporting to make the pickling process seamless for our customers.
