Abstract:
Organic chloride contamination in crude oil can cause hydrochloric acid to be formed during the hydrotreating process. Hydrochloric acid can corrode equipment, piping and vessels in both upstream and downstream units.
Quantitation of organic chlorides is currently performed using ASTM D4929. This involves distillation of a naphtha cut, followed by a multistep washing of the crude oil to remove any hydrogen sulfide and inorganic salts. The method provides a choice of three detection methods.
False positive (presence of organic chlorides) have been reported using ASTM D4929. This may be due to the formation of olefins in the distillation process that were converted by the presence of inorganic salts to organic chlorides.
The proposed method requires no distillation or sample washing and would enhance productivity by reducing sample handling. Also improving accuracy by significantly reducing the chance of false positives. Updates from ASTM will be presented.
