Abstract
The invention relates to a method of operating a high pressure ethylene polymerization unit comprising a tubular reactor, the method characterized in that the electrical conductivity of the aqueous cooling medium is monitored in at least one location. Furthermore, the invention also covers a high pressure ethylene polymerization unit comprising a tubular reactor, the unit characterized in that one or more cooling circuits comprise an electrical conductivity meter. The use of such a polymerization unit is also disclosed.
