Our company supply *6%~*9% content of the caustic soda flake.
Caustic soda is a popular strong base used in industry. Around *6% of Caustic soda produced is used by industry, *5% of which is used in the paper industry. Caustic soda is also used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. It is used in the Bayer process of aluminium production. In bulk, it is most often handled as an aqueous solution,since solutions are cheaper and easier to handle.
Caustic soda is used in many scenarios where it is desirable to increase the alkalinity of a mixture, or to neutralize acids.
For example, in petroleum industry, Caustic soda is used as an additive in drilling mud to increase alkalinity inbentonite mud systems, to increase the mud viscosity, and to neutralize any acid gas (such as hydrogen sulfide and carbon dioxide) which may be encountered in the geological formation as drilling progresses.
Poor quality crude oil can be treated with Caustic soda to remove sulfurous impurities in a process known as caustic washing. As above, Caustic soda reacts with weak acids such as hydrogen sulfide and mercaptans to give the non-volatile sodium salts which can be removed. The waste which is formed is toxic and difficult to deal with, and the process is banned in many countries because of this. In ***6, Trafigura used the process and then dumped the waste in Africa.
