Organic chlorides determination

Microcoulometry can provide quantitative analysis for halogenated compounds

Van Strien, A., Thermo Fisher Scientific

Organic chlorides can cause corrosion in pipelines, valves and condensers, and catalyst poisoning. The hydrocarbon processing industry (HPI) and others have been affected by the potential damage created by these substances. Some steps the HPI has taken to protect itself from organic chloride related damages are: Companies have a compiled specification for organic chloride in crude oil of 5 parts per million (ppm) or less. Millions of tons of crude oil are transported through pipelines and organic chloride compounds cause damage to pipelines and valves. Refineries do not accept crude oil containing more than 5 ppm organic chlorides. Hydrochloric (HCl) acid can be produc
