CLH has been using drag reducing agents (DRA) since 1989.
Gel-type flow improver was the first used, before moving onto water-based additive in 1997. From 2004, alcohol-based DRA has been used.
The DRA is a polymer that reduces the friction into pipeline, thereby increasing the flow rates and saving costs.
