The First Meros Plant for Sinter-Offgas Treatment to Be Built Outside of Europe

Siemens Metals Technologies received a contract from the Chinese steel producer Maanshan Iron & Steel Company Ltd. (Masteel) to install the first Meros plant outside Europe. The new facility will be built at the No. 1 Sinter Plant of the company's integrated iron and steel works located in Maanshan, Anhui Province, and will be capable of treating approximately 1,000,000 m3 of sinter-offgas per hour.

The Meros (Maximized Emission Reduction Of Sintering) dry-cleaning process reduces emissions of dust, heavy metals, sulfur dioxide and organic compounds to levels previously unattained applying conventional technologies. The completion of this project is expected by mid-2009.

Masteel is one of the leading iron and steel companies in China and the largest industrial enterprise in Anhui province. The company produces approximately fifteen million tons of steel each year which is primarily sold as steel sections, wire rods and medium and thick plates. Furthermore, Masteel is the largest producer of train wheels in China.

In order to drastically reduce environmental emissions from its No. 1 Sinter Plant, Masteel decided to have a Meros plant installed. A major reason for Maanshan's decision for Meros was because of the excellent results achieved with the new plant at the Sinter Plant No. 5 of the Austrian steel producer voestalpine. Since the Meros plant start-up in August 2007, it has been operating at near 100% availability and pollutants are reduced in some cases to well over 90 percent.

For the Maanshan project Siemens will supply basic data, basic engineering and key process equipment. This includes the additive-injection system, the water-injection system for the conditioning reactor, filter bags, special components of the ID (induced draught) fan (motor, frequency converter and transformer) as well as electrics and automation for the entire Meros installation. Training and also advisory services for erection, start-up and plant commissioning round off the Siemens' scope of supply. The entire project will carried out with no interference to ongoing sintering operations.

In the Meros process, adsorbents and desulphurization agents are injected into the sinter offgas stream to bind heavy metals, organic compounds, sulfur dioxide and other acidic gases. The gas stream passes to a conditioning reactor where the gas is moisturized and cooled, accelerating chemical reactions. Dust particles are trapped in a bag filter. In order to enhance the gas-cleaning efficiency and reduce costs, a portion of this dust is recycled to the offgas stream, allowing unreacted additives to once again come into contact with the offgas.

Meros is a registered trademark of Siemens AG in certain countries.

The Siemens Industry Sector (Erlangen, Germany) is the world's leading supplier of production, transportation and building systems. Integrated hardware and software technologies combined with comprehensive industry-specific solutions enable Siemens to enhance the productivity and efficiency of its customers in industry and infrastructure. The Sector comprises six Divisions: Building Technologies, Industry Automation, Industry Solutions, Mobility, Drive Technologies and Osram. In fiscal 2007 (ended September 30), Siemens Industry generated sales of approximately EUR40 billion (pro forma, unconsolidated) with around 209,000 employees worldwide.

With the business activities of Siemens VAI Metal Technologies, (Linz, Austria), Siemens Water Technologies (Warrendale, Pa., U.S.A.), and Industry Technologies, (Erlangen, Germany), the Siemens Industry Solutions Division (Erlangen, Germany) is one of the world's leading solution and service providers for industrial and infrastructure facilities. Using its own products, systems and process technologies, Industry Solutions develops and builds plants for end customers, commissions them and provides support during their entire life cycle.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
