Aqueous hydrogen chloride is produced during hydrotreating and reforming of crude oil. Moreover, it is a strong acid that may be accumulated and condensed in tanks, reactors and pipelines.
Hydrogen chloride reacts with crude oil by-products forming organic chlorides that cannot be efficiently neutralized, causing potential damage. Given the need to control the formation of organic chlorides, the oil industry established analysis protocols for hydrocarbon refining and, more specifically, for when custody is involved.
Meanwhile, hydrogen chloride may form salts when reacting with some catalysts during refining. Downstream feedstocks chloride content should be monitored and controlled to establish a proper custody transfer risk assessment.
The CI Analytics Chlorine Analyzer is a vital tool for monitoring hydrogen chloride levels in the oil industry.
