Supporting sustainable steel manufacturing in Vietnam

ABB has completed commissioning of a range of Continuous Emission Monitoring Systems (CEMS) at Hoa Phat Hai Duong Steel Complex – a key project of Hoa Phat, one of the largest steel manufacturers in Vietnam.

In recent years, Vietnam has featured among the most polluted countries in the world – a by-product of rapid industrialization. Steel production, specifically, has potential to cause air, soil, water and noise pollution. According to experts, 1 ton of steel production will emit 10,000m3 of exhaust gas, 100kg of dust, and 80m3 of waste water. Hence, an effective emission controlling system to ensure minimal environmental impact is critical for this industry.

Hoa Phat Hai Duong Complex, founded in 2007, a key project of Hoa Phat Group, is developing into a leading steel manufacturer in Vietnam. The Complex uses blast furnace technology with a capacity of up to 850 thousand tons per year, largely contributing to increase the steel capacity of the Hoa Phat Group to 1.2 million tons per year. Its model is considered as a synchro production line, modern and of the largest scale in Vietnam today. Hoa Phat Hai Duong recently chose ABB to supply, install, commission and successfully put into operation, 10 Continuous Emission Monitoring Systems (CEMS) into 10 smoke exhausting pipes at different production lines and workshops of the facility.

Technologies supplied to Hoa Phat Hai Duong Steel JSC include flow and dust measuring devices, gas analysis system, hardware, software, integrated system allowing automatic data transmission to the company and the Hai Duong's Department of Natural Resources and Environment for reporting purpose. The heart of this emission controlling system is ABB's ACX - the gas analysis system which uses the most modern, cold-dry extractive and sampling technology in the world. ACX includes everything from probe, sample lines and sample conditioning to reliable and certified analyzers of the Advance Optima series. The system can be operated from a keypad and display in the front door without opening the shelter.

Featuring advanced digital service, ABB’s Dynamic QR Code is automatically generated by the device based on the current status of the analyzer and not only contains static information like the serial number, fabrication date and software version, but also dynamic or changing information such as current measured values, temperature, pressure, flow and drift values. Remote support by ABB is offered thanks to a picture of QR code. It offers faster action, higher availability and lower cost of ownership and helps maximize system availability.

This sampling, cooling and analyzing technology is especially suitable for analyzing the concentration of emissions in chimneys of thermal, cement, steel and chemical plants and is currently being applied in almost all industrial factories in Vietnam.

Fully compliant according to European, US and Vietnamese standards, ABB’s CEMS continuously and automatically tracks the status and quality of the plant’s emissions which allows the plant owner, as well as authorities, to closely monitor the emissions at all times and take necessary measures to resolve and handle any problem in time. The system helps customers to efficiently improve productivity, optimize combustion to reduce fuel and extract emissions, decrease operating and maintenance costs of the plant and increase plant efficiency for extended lifetime of equipment.

“Our long standing presence in the country as a leader in emission monitoring technologies and our positive reputation among existing customers throughout the country have resulted in earning the customer’s trust in ABB CEMS. Our CEMS not only helps Hoa Phat to achieve its optimal performance and cost savings, but also to increase uptime through reduced maintenance and calibration time. Furthermore, CEMS data transmission also establishes visibility of emission status and allows the customer to act when necessary to minimize impact on the environment”, said Nguyen Van Tu, ABB’s Manager for the Measurement and Analytics business in Vietnam.

ABB CEMS has been used widely in Vietnam, not only in the steel sector (such as Mien Nam Steel Company, Ton Phuong Nam, Ton Dong A, etc.) but also in other sectors such as cement (Song Gianh, Xuan Thanh, Van Hoa, Tam Diep, etc.) and the power sector (Uong Bi, Na Duong PP, Mong Duong 1, Mong Duong 2, Nghi Son PP, etc.).

ABB started its operations in the country in 1993. In the 25 years since, it has grown to be a reliable partner in the field of technology, providing turnkey solutions and services in the market. In addition, ABB facilities manufacture transformers, high voltage components and medium voltage power products for customers across the globe. It employs some 900 employees across Hanoi, BacNinh, Danang and Ho Chi Minh.
