Some compounds survive fractionation and are destroyed during hydro-treating desulfurization of the naphtha. When present, they result from contamination in some manner, such as disposal of d492 solvent used in many dewaxing pipeline or other equipment operations.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: 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.

No other units of measurement are included in this standard.

ASTM D – TSHR International B.V.

Hydrochloric acid can be produced in hydrotreating or reforming reactors and the acid accumulates in condensing regions of the refinery. ASTM D method Procedure B covers the determination of organic Chlorine in the washed naphtha fraction of crude oil by oxidative combustion followed by microcoulometric titration. Unexpected concentrations of organic chlorides cannot be effectively neutralized and damage can result.

The chloride content of the naphtha fraction of the whole crude oil can thereby be obtained. Hydrochloric acid can be produced in hydrotreating or reforming reactors and the acid accumulates in condensing regions of the refinery.

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. Organic chlorides are not known to be naturally present in crude oils and usually result from cleaning operations at producing sites, pipelines, or tanks.
