Hi,
We r having the facility of LPG production in Isomerization unit. Catalyst is chlorinated & needs regular dosing of chlorinating agent. To arrest any chloride slippage, chloride guard for these stream is provided. However, chloride can slip into LPG during any upset or start up of the unit. What are the methods for detection of such carry over of Cl in LPG stream? Detection by dragger tube will be feasible in LPG? What necessary steps to be taken in downstream facility once carry over has taken place?
What are normal chloride level should be considered for design a Cl-guard?

Thanks & regards.

Detector tubes, like Drager, are suitable for inorganic chloride (hydrochloric acid HCl) in hydrocarbon gases. However, total (organic+inorganic) chloride can be quantitatively determined by using commercially availble laboratory instruments. One such equipment is manufactured by Mitsubishi Chemical.

Could somebody give me some knowledge about the chloride guard?

Thanks.
