Chlorine & Hydrogen Treatment
The chlorine and hydrogen produced from the electrolytic cells are important chemical feedstocks that participate in a wide range of chemical reactions and are involved in the production of various chemical products.
1.Chlorine
Chlorine is an essential building block for the manufacture of numerous products that we rely on every day across the world. It is highly oxidizing and highly toxic.
Chlorine has many critical uses including:
(1)Disinfectants to keep water clean to drink and swim in
(2)Ingredients for medicines
(3)Chemicals for modern materials such as PVC and polyurethane
(4)Battery and microchip materials
Examples of chlorine applications include:
The specifications of chlorine gas produced from the electrolytic cells are as follows:
|
# |
Item |
Value |
|
1 |
Purity (dry basis) |
≥ 98.5 vol.% |
|
2 |
O2 |
≤ 0.5 vol.% |
|
3 |
H2 |
≤ 0.03 vol.% |
|
4 |
H2O |

|
5 |
Temperature |
~ 85 ℃ |
|
6 |

~ 20kPa |
Chlorine gas produced from the electrolytic cells typically requires the following treatment steps (depending on specific requirements):
Chlorine gas is first dried and liquefied, and then gasified to obtain chlorine gas with a purity of over 99.9%.
2. Hydrogen
Hydrogen is one of the key energy sources for the future of the world, while also serving as an important chemical raw material. It is both reductive and explosive in nature.
Hydrogen can be used as:
(1) A building block for chemicals such as Ammonia and Peroxide
(2)A fuel for buses and boats
(3) A heating fuel
(4)A chemical for steel production
(5)An alternative to fossil fuels to help reduce the world's carbon footprint
In chlor-alkali plants, hydrogen is often used to produce HCl. Some companies use pressurized filling as a product for external sales. It is also used to make fuel and generate steam.
