| 摘要 |
<p>The invention relates to a method of operating a high pressure ethylene polymerisation unit comprising a tubular reactor, the method characterised 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 polymerisation unit comprising a tubular reactor, the unit characterised in that one or more cooling circuits comprise an electrical conductivity metre. The use of such a polymerisation unit is also disclosed.</p> |
