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 operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
