A brief look at the history of caustic soda flakes

Sodium hydroxide (caustic soda flakes) was first prepared by soap makers.

This method was implemented based on the soap preparation instructions published in a book in Arabic.

This book was compiled by the king of Yemen named “Muzaffar Yusuf ibn Umar ibn Ali ibn Rasool”. This method is considered as one of the industrial inventions of that period.

In this method, it was said that water should be passed through the alkaline solution; Therefore, the final product will be sodium hydroxide compound.

Alkaline composition in this method, impure sodium carbonate and quicklime or calcium oxide were selected.

It is interesting that most of the soap making industries in European countries based the product preparation method on these innovations and followed it.

In 1791, French chemist and surgeon Nicolas LeBlanc (1742-1806) invented a process for the mass production of sodium carbonate, natural “soda ash” (= impure sodium carbonate obtained from the ashes of sodium-rich plants).

This new method replaced the previous unconventional method. However, in the 20th century, the main method of producing solid sodium hydroxide or caustic soda flakes is the electrolysis of sodium chloride. We will talk about this in the next section.

Uses of caustic soda flakes 1. Soap and Detergent Industry: Caustic soda is an essential ingredient in the production of soap and detergents. It is used to neutralize the fatty acids present in oils and fats to form soap.

2. Pulp and Paper Industry: Caustic soda is used in the manufacture of paper and pulp as a bleaching agent. It helps to brighten the paper and remove impurities.

3. Water Treatment: Caustic soda is used in water treatment plants to adjust the pH levels of water. It helps to remove impurities and pollutants, making the water safe for consumption.

4. Textile Industry: Caustic soda is used in the production of textiles to remove impurities and improve the quality of the fabric. It is also used as a degreasing agent.

5. Chemical Industry: Caustic soda is used as a raw material in the production of other chemicals, such as chlorine and sodium metal.

6. Drilling Fluid: Caustic soda is used in oil and gas drilling operations to maintain the pH levels of drilling fluids. This helps to prevent corrosion of the drilling equipment.

7. Cleaning and Degreasing: Caustic soda is used as a cleaning agent for various surfaces, such as ovens, drains, and metal surfaces. It is also used as a degreaser for removing grease and oil from metal parts.

Caustic soda flakes production method

Solid caustic soda or soda flakes (sodium hydroxide flake) is actually produced from liquid caustic soda. In this method, membrane cell technology is used. The solid caustic soda that is prepared in this way has the best quality and does not contain pollutants such as heavy metals.

The product of this process is very absorbent and soluble in water and is used in many different industries.

The purity of this product is at least 97%. Solid sodium hydroxide is generally packed in polyethylene or polypropylene (PP/PE) bags with a standard weight of 25 kg.

We will explain more about the packaging of this product in the next sections.

Also, sodium hydroxide (NaOH) is an inorganic acid (mineral) compound. This composition is prepared based on a solid metal which is sodium. Soda is solid, white and very caustic, and is included among alkaline salts.

Solid caustic soda is usually available in the form of wide balls, flakes, granules and standard ready solutions with a concentration of 30% and 50% in different quantities.

Sodium hydroxide forms a saturated solution with a concentration of approximately 50% (by weight) with water. Sodium hydroxide is soluble in water, ethanol and methanol. This alkaline material easily absorbs moisture and carbon dioxide in the air.

Almost the largest volume of caustic soda flakes or caustic soda is produced through electrolysis of sodium chloride solution.

In the electrolysis method, one of three types of mercury electrochemical cells, diaphragm cells and membrane cells are used. The electrolysis process generally produces 2.25 tons of 50% caustic soda per ton of chlorine consumed.

The raw material for the production of solid caustic soda is common salt (sodium chloride), which is usually found in the form of underground sediments and is driven to the surface of the earth as a solution in a water source through high-pressure pumping.

Sodium chloride solution is called salt, which is the primary feed for the production of caustic soda flakes.

In the following, in order to better understand what caustic soda is, the types of liquid caustic soda production methods that are necessary for the production of caustic soda flakes are listed separately.

1. Production of caustic soda by mercury cell electrolysis method In the traditional method, electrolysis is performed to produce solid caustic soda in mercury amalgam tube or diaphragm tube. The ion exchange membrane cell for performing electrolysis has better environmental and economic benefits.

In the United States, the main method of producing soda in electrolysis is through the diaphragm cell, while mercury and membrane cells are more commonly used in Europe. Due to environmental considerations and government decisions, mercury tubes gradually became obsolete.

In the mercury cell, sodium is discharged as sodium mercury amalgam ions and chloride ions are discharged as chlorine. The amalgam is transferred to a completely separate chamber where it reacts with water.

Finally, sodium hydroxide solution and hydrogen gas are produced.

2. Production of caustic soda by cell diaphragm electrolysis method:

The diaphragm cell is usually made of asbestos. In this cell, a flow of salt water occurs from the anode to the cathode and separates the space of chlorine and hydrogen gas through a diaphragm.

By discharging hydrogen ions, hydroxide ions accumulate in the cathode compartment with dissolved sodium ions and produce sodium hydroxide (soda).

The return migration of hydroxide ions from the cathode to the anode is prevented by the liquid flow rate from one chamber to another.

3. Production of soda flakes from membrane cell electrolysis method: In the membrane process for soda flakes production, the ion exchange membrane acts as a barrier against gas and liquid flows, allowing only sodium ions to pass through both chambers.

Sodium ions pass through the membrane in hydrated form and sodium hydroxide is produced in the cathode where hydrogen is released.

Chlorine gas is released in the anode. The membrane in this method is a copolymer of tetrafluoroethylene or a similar fluorine monomer.

You can see a view of these reactions in the figure below:

A simple comparison between all three methods above in the production of caustic soda flakes In the case that the cost of electricity consumption to produce caustic soda flakes is cheaper and a product with high concentration and purity is produced, mercury cells are cheaper than diaphragm cells; But mercury must be removed as waste water.

Diaphragm cells need a lot of heat energy to concentrate the soda solution.

If they have a cheaper structure, they can be even cheaper than mercury cells.

The use of membrane cells for the production of caustic soda is growing due to lower initial capital, lower energy costs and the absence of environmental problems.

The product obtained by the membrane cell method has a higher purity.

Membranes in this method can pass a different current in the solution and carry out the production process with a cheaper price of electricity consumption.

4. A look at the chloralkali process to produce caustic soda flakes Solid sodium hydroxide is industrially produced as a 50% solution by chemical changes in the chloralkali process. In this process, chlorine gas is also produced. Solid caustic soda is obtained by evaporating water from this solution.

Solid sodium hydroxide is chemical produced as a 50% solution by industrially, changes in the chloralkali process. In this process, chlorine gas is also produced. Solid caustic soda is obtained by evaporating water from this solution.

You can see the reaction of producing caustic soda with alkaline sodium carbonate solution in the following section (this method was used in the old days): Ca(OH)2+Na2CO3 ” CaCO3+NaOH The above process was replaced by the Solvay process in the late 19th century. The Solvay process, in turn, was replaced by the chloralkaline process; Something that is used in the industry today to produce caustic soda flakes.
