Removal Sludge Oil

The plant decommissioning starts : plant piping and tanks are opened with cold cutting techniques, any liquid or residual sludge it is possible to pump out is removed using pneumatic pumps and collected in storage drums.

Tanks are ventilated to remove any organic lead in the air, and explosive potential levels are checked. When acceptable levels have been reached operators enter the tanks and clean the surfaces to attain a gas-free status. After this, hot cutting is carried out and the tanks and rest of the plant are sectioned, pickled and flamed out until no organic lead is present.
