Before the extraction

• The chlorine containers must be stored at least for 8 hours in

the container room so that the content can adapt the ambient

• Turn chlorine drums on the support until the dip pipe and the

riser pipe are placed vertically (observe the markings on the
drum).

• Check tightness.

Connection

• Dry the piping and the withdrawal system with dry nitrogen or

dry air.

• No foreign matter must get into the plant.

Withdrawal of gaseous chlorine

In case of higher chlorine requirement several chlorine containers
of the same temperature have to be connected with header lines.

Withdrawal of liquid chlorine

• Within chlorination plants only possible from chlorine drums.
• Application of an evaporator is necessary.

• Withdrawal of gaseous chlorine:

Observe residual pressure of ca. 2 bar.

• Withdrawal of liquid chlorine:
