Removal of trapped hydrocarbons from ethylene dryer bed
Removal of trapped hydrocarbons from ethylene dryer bed
(OP)
Recently Ethylene dryer bed got fully choked, taken out of service and isolated. While N2 purging to remove hydrocarbons entrapped there is no flow of N2 through the bed. What are the alternate methods to make the bed hydrocarbon free?

A solution that might work if purging is impossible, is to have the bed water-flooded. This leaves a lot of mess behind but could be the only way to go.
