United Kingdom
| Technique | Description | Applicability |
|---|---|---|
| (i) Manual crude oil tank cleaning | Oil tank cleaning is performed by workers entering the tank and removing sludge manually | Generally applicable |
| (ii) Use of a closed-loop system | For internal inspections, tanks are periodically emptied, cleaned and rendered gas-free. This cleaning includes dissolving the tank bottom. Closed-loop systems that can be combined with end-of-pipe mobile abatement techniques prevent or reduce VOC emissions | The applicability may be limited by e.g. the type of residues, tank roof construction or tank materials |
