I am working in a close loop system. The system flow is about 500 KMTPD and system volume is
about 10 KMT. I am seeing a chloride increase of about 8 PPM every month. This is a small amount of leak.

The analysis method by water treatment contractor measures accuracy of +/- 10 PPM and cannot detect chloride increase across exchangers due to large flows.

There are several sources of chloride leaks like brine or sea water exchangers and we do not which one is the source. We tried to lower the cooling water flow to individual exchangers to get more increase in leak to be detected by lab.

Hydrotesting all suspect exchangers is a shutdown job.

Currently system is managed by draining and refill at 150 PPM , but costly as we loose chemicals and water. Can someone share experience of simmillar leaks and method employed. Also what is chloride analysis method currently used which is best for cooling waters.

Sorry for the english before. Thanks Art for the guidance and will remember lifetime and improve.

If you are going to try to communicate in the English language, then I strongly recommend that you double space between sentences. That is the traditional element of style; books and this Forum use single space - which is an attempt to save space. I always prefer double space because it clearly segregates complete sentences and thoughts.

It is a great difficulty and a source of reading errors for anglophones who try to de-cyper sentences without spaces between them. It is not only a courtesy to your readers (who are trying to help you), but also an aid for them to understand what you are writing.

If you learned English in a class, then you were taught this fact of English script. Also, this is a Chemical Engineering Forum and not a chat room where neophytes and teenagers "text" each other in cute and clever codes.

Thank you.
