Vacuum pump issues

This post was last edited by sunjl1981 on 2013-1-6 at 23:14. Under normal circumstances, what is the purity of chlorine gas coming out of the vacuum pump? It had never been measured before; now it’s 90.6 – I’m not sure whether that’s high or low. Also, for a plant with a capacity of 250,000 tons, what size of pipes are used for the dechlorination condensate? # + +
The purity of chlorine is between 90% and 94%; the highest level reached was 94.5%. It involves 150,000 tons of chlorine water in pipes with a DN100 diameter
Reply to 1# Zhang Yongguo: A chlorine purity of 90.6% is indeed a bit low; our highest level has been 96%, and the normal value should be around 94%. The loss of chlorine after drying wet chlorine should not exceed 1%. The diameter of the chlorine condensate pipe can be calculated; for 250,000 tons, DN150 is sufficient.

Reply to 5# Yang Weiqian: You copied someone else’s work – where are your own ideas?
By purity, the poster is referring to wet chlorine gas, right? ? The criteria here are the same as those used in the main pipeline; a value of over 98% is considered acceptable (for dry chlorine gas)
