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
