TAN THANG CEMENT APPLIES TECHNOLOGY 4.0 TO REDUCE ENERGY CONSUMPTION
Cement production is one of the energy-consuming industries, so finding the most effective energy-saving solutions to cut costs and increase profits is always a matter of concern for businesses.
TanThang Cement Plant is invested and built on an area of 60 hectares in TanThang commune, QuynhLuu district, NgheAn province with an investment capital of more than 5,000 billion VND.
With the goal of producing high quality products that meet the strict criteria of world markets, TanThang Cement proactively welcomes the trend of "Industrial Revolution 4.0" by using modern equipment and technology imported from the EU and G7.
TanThang Cement is operating with a capacity of 5,000 tons of clinker/day, equivalent to 2 million tons of cement/year.
TanThang Cement Plant has invested in a synchronous equipment system and technological line from FLSmith - Denmark including Atox Mill material grinding machine, coal grinding machine, 2-support clinker kiln... This is one of the most advanced lines today thanks to the application of new technological solutions for high productivity and energy saving.
In particular, the ABB (Switzerland) electrical automation system is at a high level, centrally controlled to synchronously control the factory's operations, connecting electronic, mechanical and environmental technologies together. This system only consumes a minimum of 90 kW/ton of cement, consumes less than 730 kCal/kg of clinker and is considered a low consumption level in the current cement industry.
Mr. Nguyen Xuan Hung - Head of Technology Department, TanThang Cement calculated: "The standard of 1 ton of clinker consumes about 60-61 kWh, but at Tan Thang it is 57-58 kWh/ton. The old technology for producing cement consumes 33-34kWh/ton, but at Tan Thang it is 30-31 kWh/ton of product. Thus, from input to output, a normal product consumes about 95 kWh/ton of product, but at TanThang Cement Plant it is about 90 kWh/ton".
In particular, TanThang Cement has deployed a waste gas thermal power plant under the BOT model. Accordingly, the total power consumption of the factory is from 23-25MW/h, using waste gas thermal power with a generating capacity of 7MW/h, thus saving up to 30% of total power consumption. The implementation of a waste gas thermal power project to utilize excess heat will help save fuel, reduce dust emissions, and make production activities more environmentally friendly.
Central control room, controls all factory operations
Mr. Hung shared that recently, when facing difficulties in coal supply, the factory has improved the use of alternative fuels (waste oil, waste) to burn in the furnace while still ensuring production requirements and environmental requirements. These fuels are used by the factory to replace 30% of coal, helping to save production costs estimated at more than 150 billion VND.
In addition to investing in energy saving, the factory also focuses on environmental protection. Unlike other cement factories that are often associated with high dust concentrations, emissions containing carbon oxide (CO), carbonic (CO2) pollution, and dust, at TanThang Cement Plant, the "chimney has no smoke" because the entire production line is located in a closed system.
Currently, at TanThang Cement Plant, the output dust concentration is always less than 30 mg/Nm3 , the cement grinding area is less than 20 mg/Nm3 . This indicator fully complies with, and even better meets, the current regulation of 100 mg/Nm3 in QCVN 23: 2009/BTNMT. The generated dust is completely treated with the most advanced technology: using bag dust filters combined with electrostatic dust filters. All environmental monitoring data are transmitted directly to the Nghe An Department of Natural Resources and Environment for inspection and supervision.
“The current environmental standards in Tan Thang are equal to the requirements of European standards and exceed the requirements of Vietnamese standards,” Mr. Nguyen Xuan Hung emphasized.
