Slurry pipeline

The term slurry pipeline has two meanings, one that dates back to the era of collieries, the other more recent and related to the fight against climate change.

Slurry pipelines in coal transport

Under its first definition, a slurry pipeline is a pipe used to transport coal suspended in air or water. This type of slurry pipeline, used in coal exploitation, generally travels short distances, usually a few dozen kilometres.

Slurry pipelines and climatic change

A slurry pipeline may also be a gas pipeline used to transport carbon dioxide generated by processes used to capture CO₂. This type of slurry pipeline is used to transport carbon dioxide gas at high pressure and in a liquid or supercritical form, from concentrated production centres (energy plants, factories, etc.) to storage sites (saline aquifer, depleted oil wells, etc.).
