Hydrogen chloride in crude oil products

Hydrogen chloride in crude oil products


The aqueous form of hydrochloric acid is produced during hydrotreating or reforming operations in refineries. This acid species may be accumulated and concentrated in tanks, reactors, and pipelines. In addition, HCL reacts with crude oil by-products forming organic chlorides that can not be efficiently neutralised and damage can result. Given the necessity to control the organic chlorides formation the oil industry established analysis protocols for hydrocarbon refining and more specifically when custody is involved.
