Chapter 999 New Alkali Production Process
In turn, the aluminum semi-finished products in Hindai Town are transported to Beira and Tete by rail and water transportation for deep processing, and are made into daily utensils and electrical equipment parts, forming Industrial closed loop.
Of course, if East Africa wants to, it can deploy related industries in Hindai Town, and it has indeed done so. However, the Zambia River estuary where Hindai Town is located does not have the same advantages as other river estuaries. Shipping is It is a big problem, and the refining and preliminary processing of bauxite causes great pollution, especially to water sources, so it is not suitable to build large cities locally, and the cities of Beira and Tete, which are closest to Hindai City, bear the responsibility. A lot of subsequent processing work.
The potential of Hindai Town is still good, but if it wants to be developed, unless East Africa comprehensively develops and manages the Zambezi River, this is also the main reason for restricting the development of Hindai Town. Although the Zambezi River is the largest river in East Africa, The second largest river, but its navigation conditions are too poor. At least from Hinde upwards, it can only be navigable to the city of Tete. This level has no advantage compared with some rivers in the East African coastal plain.
……
May 1901.
When the First Five-Year Plan in East Africa was in full swing, the East African Ministry of Science and Technology came to Nairobi City University for inspection. A new technology was born here, which attracted the attention of the Ministry of Science and Technology.
The school's scientific research team received the personnel of the Ministry of Science and Technology. The leader of the scientific research project team, Professor Robben, and his students conquered the new alkali production process.
Roben: "my country's alkali production industry started in the 1980s. Although a set of equipment was introduced in the 1970s, the output was low due to the lack of relevant talents. It was only in the 1980s that my country started to Europe recruited a large number of technicians and workers, and built alkali production plants in Mbeya City and many other places.”
East Africa began its initial industrial construction phase in the 1970s, which can be said to be relatively bumpy. Taking advantage of the economic crisis at that time, a large number of equipment was introduced. However, due to the lack of technical personnel, many industrial equipment could not be put into production and were difficult to maintain.
However, the situation in East Africa was a little better than that of the Far East Empire at that time. Although East Africa itself lacked relevant talents and technology, East Africa had the technical guidance of the Hechingen Consortium.
The Hechingen Consortium can be said to have played the role of the Soviet Union in the First Five-Year Plan of the Far Eastern Empire in its previous life in the early industrial construction of East Africa.
The Hechingen Consortium has a large number of companies under its umbrella, so it is relatively easy to obtain technical and professional talents. On this basis, East African industry could develop in a bumpy way in the 1970s.
Without this premise, no matter how much industrial equipment East Africa introduced in the past seventy years, it would be equivalent to spending money to buy a pile of scrap metal.
Fortunately, in the 1980s, East Africa introduced a large number of technical personnel from Europe and the United States. With the development of education in East Africa and the return of overseas students, the industry in East Africa stabilized. In the 1990s, the industry in East Africa achieved greater development. , has become relatively mature in the fields of capital, technology, labor and other fields.
The alkali production industry in East Africa also ushered in great development in the 1990s. Currently, East Africa's soda ash production is self-sufficient, and some of it is exported.
The special industrial and social conditions of East Africa have led to a relatively strong demand for soda ash in East Africa. This starts with the use of soda ash.
Roben introduced: "Soda ash, commonly known as soda, has a chemical composition of sodium carbonate. It is widely found in nature and distributed around the world. It is divided into heavy alkali and light alkali according to density.
According to the use, it is divided into industrial grade soda ash and food grade soda ash. Industrial grade soda ash is one of the main raw materials of flat glass. It can also be used as a cosolvent for smelting and mineral processing. Flotation agent and desulfurization agent for steelmaking. In the textile field, soda ash can be used as a water softener in the textile production process.
Food grade soda ash can be used as a pasta additive, serving as a neutralizing agent, leavening agent, etc. It functions as a buffering agent and dough improver to increase the taste and flexibility of pasta. It can also be used as an auxiliary additive in the production of MSG and soy sauce. ”
Among these, in addition to general uses, the importance of soda ash to the glass industry and detergent industry is an important driver of the development of the soda ash industry in East Africa. In this time and space, for the development of the automobile industry, under the guidance of Ernst, the first piece of industrial mass-produced flat glass was produced in East Africa. East Africa’s early emphasis on sanitary conditions also destined East African society to attach great importance to detergent products. Pay attention to.
For example, for the cleaning work of early East African immigrants, a large number of required products were imported from Europe, and the cost was much higher. Therefore, East Africa has been very important to the alkali production industry since the colonial era. Pay attention to.
“Currently, my country’s alkali production industry mainly adopts the Lubulan alkali production method, which is also the most mature and largest-scale alkali production process in Europe.”
“Of course, countries around the world are now using The alkali production industry is transitioning to the Solvay alkali production process. However, my country obtained the Solvay alkali production process relatively late because major countries blocked the Solvay alkali production process. It was not until after the South African War that we and Germany The relevant technology was obtained only after the relationship was further improved.”
The Solvay alkali production method is the mainstream trend in the current alkali production industry, and it is also monopolized by the great powers. It was born in the last century (the late 1860s), so at that time the East African industry could only introduce the earlier Lu Bu Blue alkali production method.
In the beginning, soda ash was mainly extracted from plants. In Europe, alkali was extracted from the juice of seaweed ash.
However, as the Industrial Revolution began in Britain in the mid-18th century, the amount of alkali required by industries such as textiles, printing and dyeing, papermaking, soap making, and glass increased dramatically. There is obviously insufficient alkali, which requires artificial production.
Later, with a large reward from the French government, the Frenchman Lübrand was the first to make a breakthrough. Lübrand’s alkali-making method came into being. In addition to salt, the raw materials used in the Lübrand’s alkali-making method include sulfuric acid and charcoal. and limestone.
This alkali production process continues to this day, including in use in European countries and East Africa. It will take more than ten years for the Solvay alkali production method to completely replace the Lubrand alkali production method.
For various reasons, the most advanced Solvay alkali production process currently accounts for a small proportion of the alkali production industry in East Africa. And just as East Africa is preparing to vigorously promote the Solvay alkali production process, East Africa's own country has also developed major technologies for the alkali production industry. breakthrough.
The emergence of the new alkali production process in East Africa is different from the Lubulan alkali production process and the Sowell alkali production process. The fundamental reason for its emergence is the resource advantage of East Africa.
The specific details of the new alkali production method in East Africa are actually the refining of alkali ores existing in nature, rather than chemical synthesis with other raw materials like the previous two.
This has to mention the distribution of natural alkali ores in the world. Generally, alkali ores are mostly contained in surface alkali lakes and exposed mineral deposits, mainly in North America, East Asia, Turkey, and most of Africa.
The Alkali Wadi of Egypt is a world-famous natural alkali mine. The ancient Egyptians were also one of the first people to utilize soda ash.
In Ethiopia, Kenya, Tanzania and other regions in the East African Rift Valley, as well as Botswana in southern East Africa, there are a large number of trona minerals, so East Africa is very rich in trona mineral resources.
The birth of the new alkali production method in East Africa was developed by the Chemistry Laboratory of the University of Nairobi. They used local alkali ores for refining and thus obtained a new alkali production process. In fact, it was mainly used in the United States in later generations. Trona method.
Professor Robben said something like Versailles: "The new alkali production process actually does not have much technical content. It can only be regarded as an unexpected discovery of mine. In the end, the experiment was successful. Its main application method is to use our The abundant alkali ores in East Africa can directly extract soda ash, and this method is cheaper than the current mainstream alkali production process in the world. If it can be realized on a large scale, it will undoubtedly make a huge contribution to my country's alkali production industry. ”
