Inauguration of the waste gas power generation system of Tan Thang Cement Factory

Delegates cut the ribbon to inaugurate the WHR power generation system.

The WHR project at Tan Thang Cement Plant is implemented by the contractor, Shanghai Conch Kawasaki Engineering Co., Ltd. The project started construction on March 25, 2024.

Thanks to the efforts and effective coordination between the parties, the project completed construction, installation and trial operation on December 30, 2024, 5.5 months ahead of schedule compared to the signed contract. This is also one of the WHR systems with the fastest construction time in Vietnam (only 9.5 months).

The WHR power generation system has a designed capacity of 9,000 kW for the Clinker production line of 5,000 tons/day. With a Gross generation capacity of 8,650 kW and a NET generation capacity of 8,035 kW, it helps save about 1/3 of the monthly electricity consumption for the entire factory. This is not only a significant technological step forward but also brings sustainable economic benefits with a payback period of only about 6 years.

With an optimized location, located right next to the Clinker Cooling Grate and Heat Exchanger Tower in the factory premises, the WHR system helps to fully utilize the heat from 100% of the waste gas generated during the production process to generate electricity, reducing emissions by about 40,000 tons of CO2/year (calculated over 330 operating days). The concentration of dust emitted into the environment is sharply reduced from 30 mg/Nm3 to only 10 mg/Nm3 - in line with strict environmental standards of the EU and G7.

This system is also an important foundation for Tan Thang to meet the conditions for requesting the "green cement" label, moving towards mass production of environmentally friendly products, meeting the trend of sustainable consumption in the market.

The WHR system brings “double benefits” in energy efficiency, saving 25-30% of the electricity purchased from EVN, helping the factory reduce 78-80 billion VND per year, while contributing significantly to energy security, reducing pressure on the national power transmission system, especially during peak season.

Speaking at the inauguration ceremony, Mr. Hoang Anh Tuan, General Director of Tan Thang Cement Joint Stock Company, emphasized that the project not only contributes to the implementation of the National Strategy on Green Growth for the period 2021 - 2030, with a vision to 2050 of the Government , but also demonstrates the responsibility of the enterprise with the commitment to bring net emissions to "0" (Net Zero) by 2050 that Vietnam has made at the COP26 Conference. Heat recovery - power generation technology is expected to create a typical production model that can be replicated in the cement industry - one of the largest energy consuming and emission-emitting industries in Vietnam.

Not only bringing economic and environmental efficiency, the process of building and operating the WHR system also creates more job opportunities for local people, contributing to promoting the socio-economic development in Quynh Luu district, Nghe An province. This is a model for cement enterprises in linking economic development - environmental protection - improving community life.

Tan Thang Cement Factory is one of the few factories in Vietnam capable of producing special cement lines such as superplastic cement and sulfate-resistant cement.

On the journey of sustainable development, Tan Thang Cement Factory has pioneered the application of modern technology following the trend of Industrial Revolution 4.0, investing in advanced production lines to help save energy and reduce emissions. The factory uses a dust filtration system combining bag filters and electrostatic dust filters, ensuring compliance with strict environmental standards of the EU and G7.
