3. INTRODUTION
• Chlorine is a hazardous and dangerous chemical. Take extreme care when handling and follow all pertinent
safety rules and regulations.
• This manual was designed for the reader to understand the proper handling, storage, service and delivery
of chlorine.
• This manual should be read fully andunderstood handling any hazardous chemicals.
4. PROPERTIES OF CHLORINE
• CHEMICAL FORMULA – CL2
• MOLECULAR WEIGHT – 71 g/mol
• DENSITY (GAS)- 3.04 kg/m3
• DENSITY (LIQUID)-1562 kg/m3
• THERMAL CONDUCTIVITY – 7.91mW/ m.K
5. UTILITIES & RAW MATERIAL
• UTILITIES
• ELECTRICITY
• STEAM
• NATURAL GAS
• INSTRUMENT AIR
• RAW MATERIALS
• SALT( NACL)
• PROCESS WATER
• ANTHRECITE COAL ( as purifier )
7. PRODUCTION METHOD
• Chlorine is mainly manufactured by electrolysis of chlorides in which chlorine is evolved as a gas at the
anode while hydrogen and hydroxide ions are formed at the cathode.
• The production of caustic soda (NaOH) and Chlorine (Cl2) is one of the most important industries.
• The basic reaction in the chlorine – caustic process
• NaCll + H2 O NaOH + ½ H2 + ½ Cl2
8. CHLORINE STORAGE FACILITIES
• Any type of chlorine container should be kept in a dry, temperature stable environment around 60-120
˚F (15-50 ˚C).
• They must also be kept out of direct sunlight and securely mounted on either trunions (ton containers)
or chained to a wall (cylinders).
• Operators, especially in earthquake prone areas, may want to secure ton containers to the ground by
strapping them to the floor.
• The storage area should be well ventilated and free of flammable materials. Iff stored outdoors, the
containers should be fenced off so that only proper personnel can Reach them.
• Containers should not be stored below ground or in heavily trafficked areas.
9. STORAGE TANK SPECIFICATIONS
• DESIGN PRESSURE – 13.5 kg/cm2
• DESIGN TEMP. - -35 TO 50 °C
• WORKING PRESSURE – 3.04 To 10.5 kg / cm2
• WORKING TEMP. - -35 TO 40
10. APPLICATIONS
• Chlorine is widely used in thousands of making of everyday products.
• Producing safe drinking water the world over. Even the smallest water supplies are sually chlorinated to
make it safe for drinking. It is extensively used in the production of Paper products and paper pastes.
• It is used in dyestuffs, textiles for decolourizing of Artificial fibres, petroleum products & chemicals,
medicines, antiseptics, insecticides, Foodstuffs, solvents and cleaners, paints, plastics, refrigerated fluids
such as HCFC’s, chloromethane.
11. SAFETY MANAGEMENT
• EYE FACE PROTECTION : wear chemical safety goggles,
• FACE SHIELD : May also be necessary
• SKIN PROTECTION: wear Chemical protective clothing e.g. aprons, asbestos gloves
• BREATHING APPARATUS SET CYLINDERS
