What medium is used to purge gasoline pipelines?
Thread Content
The facility has a small distillation unit; during the production process, there is a small amount of gasoline components as well as some water, which poses various challenges during winter production. It is difficult to deal with this issue each time it is removed using temporary pumps. I hope those in the same situation can offer some advice. Thank you!
Nitrogen purge. Remember to install a blind flange when the nitrogen line is used up
One is to purge with nitrogen. Second, low-temperature hot water can be used to provide heat tracing for protection against freezing and condensation.
Gasoline pipelines are generally washed in the reverse flow direction, and then steam purging is used to remove oil and impurities from the pipes!
First, use nitrogen to displace the oil in the pipeline, then wash it with water; after washing, purge it with steam. To prevent freezing, the remaining water in the pipeline can be removed by using nitrogen for purging
After the oil is removed from the system pipelines, they are first washed with water and then purged with steam; after the purging is complete, condensate is drained from the lowest points.

Use nitrogen for purging; if it isn’t used frequently, a blind flange can be installed – this is the best approach. If freezing still occurs during maintenance in July or August, considering the installation of heating elements is an option
