2. Handling chlorine
2.1 Physical and chemical data
Under normal conditions of pressure and temperature, chlorine is
a yellowish green gas with a pungent odour. It exists as diatomic
molecule Cl2.
It is not flammable, but can under certain circumstances promote
the flammability of metals, hydrocarbons etc.

– Helpers must pay attention to personal protection!
• Immediately remove contaminated clothes.
• Calm down injured persons and keep them warm with
blankets.
• Supply fresh air; use oxygen respirator (alternately with
inhalating steam), if possible.
– No mouth-to-mouth resuscitation!
• Fast and gentle transport to hospital
– lying
– sitting in case of difficulty in breathing
– state chlorine causticization as the cause.
First aid after causticization of the skin
• Keep calm.
• Remove contaminated clothes.
• Rinse skin with plenty of water
• Bandage the wound germ-freely

lying.
– Protect healthy eye, if necessary.
– Spread eyelids widely, let the eye move to all sides.
• Seek ophthalmologist.
– State chlorine causticization as the cause.
First aid after internal causticization

protection cap.
Valid regulations
– Regulations for accident prevention "Chlorination of water"
(GUV-V D5) with process instructions
– Regulations concerning places of work (ArbStättV))
– Technical rules for gases 280, 310 und 330
Warning
R 23: Toxic by inhalation.
R 36/37/38: Irritating to eyes, respiratory system and
skin.
Caution
Further obligations of the operating authority
Warning
Handling of chlorine containers only by experienced,
practised personnel!
Warning
This rules are valid for both full and empty
containers, as empty containers still contain rests of
chlorine and therefore are under pressure.
Warning
Strictly observe local law and regulations for
handling, transport and storage of chlorine.

2.2.6 Pressure vessels and mountings
Chlorine is being offered in two container designs:
• Steel cylinders containing 50 kg or 65 kg, equipped with one
valve for
– the withdrawal of gaseous chlorine from the upright standing
cylinder
Variant of chlorine cylinder
Fig. 3 Variant of chlorine cylinder
• Steel drums containing 500 kg or 1000 kg, equipped with
– one valve for the withdrawal of gaseous chlorine
– one valve for the withdrawal of liquid chlorine
Fig. 4 Chlorine drum
Fig. 5 Valve position of chlorine drum
Due to safety precautions, chlorine containers are only filled up to
95 % of their capacity.
• Kind of gas, weight, owner, producing date and date of the last
testing have to be noted clearly on the container. Chlorine
containers are marked by grey colour.
• No changes or repair by the user!
• Never open container valves by force. Stuck valve spindels
can be loosened by wrapping a shred with warm water
around the valve.
– Never use an open flame!
– Never use wrench lengthening!
– Return containers with stuck valves to the manufacturer.
• Observer safety precautions and the manuals of the
manufacturer!

2.2.7 Chlorine extraction
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
temperature.
• 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
• Protect containers from turning over or rolling away!
• Dry the piping and the withdrawal system with dry nitrogen or
dry air.
• No foreign matter must get into the plant.
• Mount new gaskets to the connection line.
• Connect the container.
• Slowly open the container valve.
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: Observe residual pressure of ca.
4 bar.
After the extraction
• Close container valve.
• Disconnect container from the plant.
• Screw on valve protection nuts.
• Screw on protection cap.
2.3 Checking the tightness
Before commissioning check the tightness of the whole plant.
2.3.1 Checking the chlorine solution lines and the diaphragm
non-return of the injector
• Observe the manual of the injector!
2.3.2 Checking the tightness of the vacuum lines
Vacuum lines are all lines between vacuum regulator and injector.
• Close all container valves
• Close the rate valve
• Open the shut-off valve at the injection unit
• Open motive water valve
• Switch on the booster pump
• Open the rate valve
– Floater shows gas flow or vacuummeter shows more than -
9 m w. c.: Leakage in vacuum line!
• Close rate valve
• Switch off booster pump
• Close motive water valve
• Close the shut-off valve at the injection unit
• Check the vacuum lines and the connection. If necessary,
carefully re-tighten them.
• Check tightness again!
– Floater shows no gas flow, vacuummeter shows -9 m w. c.
or less: Vacuum lines are tight.
2.3.3 Checking the tightness of pressure gas lines
Pressure gas lines are all lines from the gas containers to the
vacuum regulator.
• If the plant is equipped with a nitrogen rinsing device: Check
tightness roughly with nitrogen
• Detailed checking with ammonia
Checking the tightness with nitrogen
• Close all container valves
• Open container connection valves and all shut-off valves up to
the gas dosing system
• Open the connection valve of the nitrogen cylinder
• Slowly open the valve of the nitrogen cylinder, until the lines
have a pressure of about 10 bar (read at the manometer of
the vacuum regulator).
• Apply soap water to all components under pressure
– Formation of bubbles and/or pressure drop at manometer
Leakage in pressure lines!
– Depressurize the plant!
– Eliminate leakage!
– Check tightness again!
No formation of bubbles, pressure at manometer does not drop
significantly within one hour: Pressure lines are tight.
Checking the tightness with ammonia
See chapter 5.2.2 Checking the tightness.
Warning
Chlorine containers must never have a higher
temperature than other parts of the plant. Danger of
liquefaction and possible chlorine break-out!
Caution
At 15 °C about 1 % (DIN19607) of the content can be
withrawn per hour. In case of higher withdrawal
danger of malfunction by the formation of ice on
containers and piping!
Container size Withdrawal quantity
50 Kg 500 g/h
65 Kg 650 g/h
500 Kg 5 Kg/h
1000 Kg 10 Kg/h
Caution
Do not completely evacuate the chlorine drums.
Danger of withdrawing deposits!
Caution
Immediately close connection lines.
No moisture must get into the lines!
Warning
Do not check the tightness until the whole plant is
ready for start-up.
Danger of chlorine break-out!
Note
More possible reasons for insufficient operating
vacuum
• injector layed out too weakly or defective
• injector obstructed
• booster pump layed out too weakly or
defective
Warning
Maximum nitrogen pressure 16 bar!
Danger of damages and gas leakage when being
exceeded!

– without current input, with feedback potentiometer
Fig. 18 Terminal connections, with cheedback potentiometer
5.2 Checks before commissioning
Check tightness of the total plant before start-up.
5.2.1 Checking the gas solution lines and the non-return
diaphragm of the injector
– Observe the manual of the injector!
Warning
Before connecting, ensure that the valves of all gas
containers are closed.
Only use the intended line types!
TM04 0742 0908
Item Description
1 Vacuum line to the vacuum regulator
2 Overpressure line
3 Vacuum line to the dosing regulator
4 Vacuum line to the injector
Caution
Only tighten the union nuts of the vacuum
connections by hand. Do not use any tools!
Danger of damages!
Maximum length of the vacuum line, see chapter
2.7 Recommended diameter
Warning
Lead the overpressure line downwards, as chlorine is
heavier than air.
Connect the overpressure line to a suitable
adsorption device. If using a gas warning device:
Mount the sensor in a distance of about 10 cm from
the outlet hole of the adsorption device.
Caution
Before connecting the mains cable:
Check if the mains voltage indicated on the type
plate corresponds to the local mains voltage. Wrong
voltage can lead to damages of the product!
To ensure electromagnetic compatibility (EMC):
Signal lines must be shielded. The shield must be
connected to PE or ground on the side of the
counterpart, par exemple a controller.
Signal lines and mains lines must be guided in
different cable channels.
