5. Significance and Use
5.1 Organic as well as inorganic chlorine compounds can
prove harmful to equipment and reactions in processes involving hydrocarbons.
5.2 Maximum chloride levels are often specified for process
streams and for hydrocarbon products.
5.3 Organic chloride species are potentially damaging to
refinery processes. Hydrochloric acid can be produced in
hydrotreating or reforming reactors and this acid accumulates
in condensing regions of the refinery
