From scientific topics to practical applications

(Baonghean) - Each organization and individual operates in different fields, but they all have the idea of ​​researching and studying creative scientific and technical topics, aiming to bring material benefits to society. That is what we have recorded from the Union of Science and Technology Associations of Tan Ky district, a unique model in the system of members of the Union of Science and Technology Associations of Nghe An province.

After many missed appointments, we finally met Mr. Nguyen Hoang, a technical engineer of Song Con Sugarcane Joint Stock Company - who had just completed the scientific and technological project "Manufacturing a 1,200 m2 evaporator and renovating the equipment system so that the evaporators can be replaced with each other", aiming to improve and upgrade product quality to meet Vietnamese standards. Leading us deep into the factory's production area, standing in front of 6 giant boilers, Nguyen Hoang analyzed: Previously, the factory only had 5 boilers of 5 brands, designed by Cuba, with a capacity of 1,250 tons of sugarcane/day. This design did not operate effectively because during operation, the evaporator was clogged with deposits and the line had to be stopped for cleaning. Normally, every 10-12 days, the line had to be stopped to clean the evaporation system, thus reducing productivity and product quality. This is a concern for all leaders and employees of the company.

Having to take responsibility for his engineering degree, Nguyen Hoang proposed to the Technical Department and the Board of Directors of the company to research and exploit documents to study the design and manufacture of another evaporator, and at the same time renovate the 6-boiler evaporation system (5 working pots, 1 spare pot) so that the evaporators can replace each other during the production process. Adding 1 more evaporator means that it is necessary to install an additional valve to adjust the flow of steam. The difficulty is that currently, the DN750 steam valve is not available on the market, there are only DN800 and DN700 steam valves, the selling price of DN700 on the market is 250 million VND. Thus, the necessary problem now is to have a DN750 steam valve to operate the new boiler system. Based on the DN700 steam valve, Nguyen Hoang and the technical department designed and manufactured the DN750 steam valve, with a total cost of just over 36 million VND, more than 200 million VND lower than the DN700 steam valve. After designing and manufacturing an additional boiler and DN750 steam valve, the Company put it into operation and saw clear results. The 2010 pressing season showed that the boiler cleaning cycle was extended to 25-30 days, instead of the previous 10-12 days. Since then, the factory has increased its capacity to 2,800 tons of sugarcane/day; reduced harvesting time for sugarcane growers; improved product quality to meet Vietnamese standards for type 1 sugar on par with large domestic factories; increased recovery efficiency and production and business efficiency of the company; reduced invisible losses and other types of losses...

Not only that scientific topic, but in Tan Ky district in recent years, there have been many scientific and technological topics that have been effectively applied in social life. Mr. Nguyen Duy Thuy - Secretary of Tan Ky District Party Committee (former Chairman of Tan Ky District Science and Technology Association), said: Since the establishment of the District Science and Technology Association (from 2007 to present), it has gathered many social and professional organizations of science and technology, gathering a large number of intellectuals working in different sectors. Over the past 5 years, members of the associations and branches have had many scientific topics that have been effectively applied in social life, recognized by the Provincial Science and Technology Association. Notably, in 2007, Song Con Sugarcane Joint Stock Company implemented the topic of rapid propagation of new sugarcane varieties, effectively applied, affirming its superiority in many aspects, creating a stable raw material area for the company, actively contributing to significantly increasing income for sugarcane growers. In 2008, the Department of Industry and Trade in collaboration with the Cua Tile Cooperative successfully implemented a high-tech application project, contributing to reducing environmental pollution, significantly improving product quality, saving fuel, reducing product costs, opening up a sustainable development direction for the craft village. In 2009-2010, the project "processing organic microbial fertilizers on a family scale" was approved by the Provincial People's Committee, with the Department of Agriculture as the project owner. Up to now, this project has been widely developed in the district, accepted by farmers and effectively implemented on a large scale. Every year, the amount of organic microbial fertilizers increases, contributing to increasing crop yields by 20%, reducing costs for agricultural investment.

Mr. Tran Cong Duong - Chairman of the Provincial Union of Science and Technology Associations, assessed: The Union of Science and Technology Associations of Tan Ky district is the only model in the system of members of the Provincial Union of Science and Technology Associations. After 5 years of operation, the Union has developed 8 member associations and branches, operating effectively. Each association and branch operates in a different field, but the local intellectuals and scientists have actively participated in propagating and disseminating scientific and technological advances, promoting the process of rural industrialization and modernization, and actively participating in the process of economic and social development of mountainous districts. The diverse activities of the association members in the organization have contributed to disseminating the policies of the Party and the laws of the State to all classes of people. The role of the Union contributes significantly to the development of... The intellectual team of the association has implemented the objectives of the association, promoting the intelligence and role of the intellectual team, those working in science and technology. Those contents are shown in research, dissemination, application of scientific advances, with high criticality, especially in projects on environmental protection...

Tan Ky is a locality with great potential for developing agricultural, forestry and industrial economy, so in recent years, the local Party Committee and government have paid great attention to the field of encouraging individuals and groups to research scientific and technological topics that are suitable for reality. Not satisfied with what the Union of Scientific and Technical Associations of the district has achieved, the associations and branches are continuing to contribute topics of high practical value that the locality needs.
