Some compounds survive fractionation and are destroyed during hydro-treating desulfurization of the naphtha.

It is important for the oil industry to have common methods available for the determination of organic chlorides in crude oil, particularly when transfer of custody is involved.

Some compounds break down during fractionation and produce hydrochloric acid, which has a corrosive effect.

Other halides can also be used for dewaxing crude oil; in such cases, any organic halides will have similar impact on the refining operations as the organic Chlorines. Some compounds break down during fractionation and produce hydrochloric acid, which has a corrosive effect. When present, they result from contamination in some manner, such as disposal of chlorinated solvent used in many dewaxing pipeline or other equipment operations. Organic Chlorine species are potentially damaging to refinery processes.

ASTM D – 17 Standard Test Method for Determination of Organic Chloride Content in Crude Oil

It is the responsibility of the user of this standard to establish appropriate safety, health, awtm environmental practices and determine the applicability of regulatory limitations prior to use. Organic chlorides are not known to be naturally present in crude oils and usually result from cleaning operations at producing sites, pipelines, or tanks.

Unexpected concentrations of organic chlorides cannot be effectively neutralized and damage can result.

Hydrochloric acid can be produced in hydrotreating or reforming reactors and the acid accumulates in condensing regions of the refinery. No other units of measurement are included in this standard.
