Soda ash, also known as sodium carbonate, is a versatile compound with applications spanning the chemical, glass, detergent, and textile industries. It plays a crucial role in neutralizing acids, regulating pH levels, and enhancing the performance of various processes.
Two primary forms of soda ash dominate the market - soda ash light and soda ash dense. The distinction lies in their physical properties, and the choice between them depends on the specific needs of your application.
Soda ash light, with its lower bulk density and finer particles, offers unique advantages in certain applications. It dissolves more rapidly in water, making it ideal for industries where quick dissolution is crucial. Additionally, its lighter nature often translates to improved handling and transportation efficiency.
For businesses requiring precise control over pH levels, such as the water treatment sector, soda ash light proves to be an excellent choice. Its solubility characteristics enable faster and more accurate adjustments to achieve the desired alkalinity levels.
On the other hand, soda ash dense boasts a higher bulk density and larger particle size. This form is particularly suitable for applications where rapid dissolution is not a primary concern. Industries such as glass manufacturing often prefer soda ash dense due to its ease of handling and reduced dusting during transportation and storage.
The higher density of soda ash dense also makes it a cost-effective option in scenarios where space utilization is a critical factor. When considering transportation costs, a higher bulk density allows for more soda ash to be shipped in a single consignment, reducing overall logistics expenses.
Now that we understand the differences between soda ash light and dense, the next crucial step is selecting the right supplier for your business. This decision is pivotal, as it can impact product quality, consistency, and, ultimately, your bottom line.
Consider the following factors when evaluating potential soda ash suppliers:

According to their own production needs and application scenarios, determine the type, quality requirements and quantity of soda ash required.
Considering the supplier's enterprise scale, production process, product quality, price and after-sales service and other factors, choose the right supplier. It can be selected through field visits, consultation with industry experts, and reference to customer evaluations.
Before signing the purchase contract, it is necessary to clarify the quality standard, price, delivery time, after-sales service and other terms of the product to protect its own rights and interests.
By improving the production process, the reaction efficiency and conversion rate of soda ash are increased, and the production cost is reduced. For example, the use of advanced carbonation technology, optimize crystallization process, etc.
When using soda ash, it is necessary to reasonably control the dosage according to different application scenarios and needs. Avoid waste and improve the efficiency of soda ash.
For some specific industries, such as the glass industry, recycling soda ash can be considered to reduce production costs and reduce environmental pollution.
In short, soda ash, as an important inorganic chemical raw material, plays an important role in many industries. Understanding the meaning, classification, application scenario, market demand and trend of soda ash, as well as mastering product evaluation, supplier comparison and purchase guide, is of great significance for enterprises and individuals in the production, procurement and use of soda ash. At the same time, continuous exploration of the improvement of soda ash production methods and the solution of efficient utilization problems will help promote the sustainable development of soda ash industry.
Soda ash can be divided into light alkali and heavy alkali, the main difference is its physical properties, such as loose density, particle size, shape and so on;
The density is different: the density of light soda ash is usually 500~600 kg/cubic meter, and the density of heavy soda ash is ~ kg/cubic meter.

The preparation process is different: light soda ash is mainly produced by ammonia-alkali method, raw salt and limestone as raw materials, through chemical synthesis to produce light soda ash, and then through solid phase water to produce heavy soda ash;
Heavy soda ash can be produced by natural alkali process, with trona as raw material, through evaporation or carbonization to produce heavy soda ash, or from light alkali through water method or extrusion method. It can also be prepared by ammonia alkali process and combined alkali process;
The price is different: due to the additional process required for preparation, usually a ton of heavy soda ash is 100.300 yuan more expensive than light soda ash.
Uses: Light soda ash is mostly used in food, smelting, printing and dyeing, chemical industry, medicine, daily chemical washing supplies, glass manufacturing, etc. Heavy soda ash is mostly used in the manufacture of high-grade glass such as flat glass, optical glass, and high-grade utensils.
The first step in the production of soda ash by the ammonia-alkali process is to dissolve ammonia gas in water to form ammonia water. Ammonia can be obtained by high-temperature combustion, ammonium oxide, or ammonium distillation. When ammonia gas is passed into water, the solubility decreases with the increase of temperature. Therefore, in the process of ammonia absorption, the method of pressurizing ammonia at low temperature is generally used to dissolve ammonia, so that the ammonia concentration reaches 25% to 30%.
The ammonia water is evaporated to produce a concentrated ammonia water. The evaporation device generally adopts multi-effect evaporator, and the multi-stage evaporation improves the thermal efficiency. In the process of ammonia evaporation, the separated water vapor is cooled by the cooling condenser to form ammonia, which is supplied to the next level of evaporator.
Limestone is reacted with concentrated ammonia water to obtain ammonium bicarbonate. The reaction equation is as follows:
CaCO3 + 2NH3 + H2O → Ca(HCO3)2·2NH3
Limestone digestion needs to be carried out under high temperature and pressure, and it is difficult to obtain products at normal temperature. The ammonium bicarbonate in the reaction product is generally unstable and needs to be heated to dissociate to obtain ammonium hydroxide and carbon dioxide. After dissociation, the product was filtered and separated to obtain ammonium bicarbonate mother liquor.
Ammonium bicarbonate mother liquor contains impurities, which need to be removed by filtrate treatment. In the treatment process, asbestos filter cloth or rotary filter is generally used to separate impurities.
The ammonium bicarbonate solution is evaporated through a multistage evaporator to obtain soda ash. Ammonium bicarbonate is first removed from the suspension in a high-speed centrifugal filter, and then evaporated through a multi-stage evaporator, so that the concentration is continuously increased until it reaches a saturated concentration. At saturated concentration, the product has almost no water, to meet the requirements of soda ash. At the same time, during the evaporation process, carbon dioxide is released by heating and pressurizing to produce sodium carbonate.
After obtaining soda ash, subsequent processing such as powder making, cube making or crystal making can be carried out to make it meet customer needs.
Through the above steps, the ammonia alkali process can produce high purity soda ash. Of course, there are many details to pay attention to in the actual production process, such as equipment selection, operating conditions control, environmental protection and other issues.
However, understanding the main steps in the production of soda ash by the ammonia-alkali process will be a very beneficial thing for those engaged in related industries.
