Reducing CO2 Emissions During Paper Drying

13.12.2010
New software from Siemens reduces carbon dioxide (CO2) emissions from paper manufacturing. With Sipaper APC (Advanced Process Control) DrySec, the amount of steam required for drying can be reduced significantly.

The plant thus also uses less fuel to raise steam without the need for any additional investment. The solution has already been implemented for the production of newsprint at a plant of the Rhein Papier paper company in Hürth, Germany, where it has lowered the need for live steam by more than three percent.


Most of the energy consumed in the paper production process is used to dry the very wet webs of paper. The webs are passed over multiple rolls, called dryer cylinders, which are heated to different temperatures using steam. The paper thus gradually releases its moisture to the atmosphere in the drying hood. In order for such a system to operate with high efficiency, the temperatures of the more than 30 cylinders over which the paper web runs must be perfectly matched to the air conditions inside the drying hood. Imbalanced settings lead to unnecessarily high steam consumption or, in the worst case, to condensation in the drying hood and thus to production outages.

The Siemens software solves this problem. It derives the optimal steam pressure as a function of the thickness and weight of the paper. Using these data, the system calculates optimized target values for all drying-relevant parameters and adapts these to the prevailing process conditions. The software also regulates the volume and temperature of the hood intake air and the volume of the hood exhaust air, depending on the moisture in the room. This ensures that humidity is never too high, and the paper can dry ideally.

Sipaper APC DrySec is a module of the Sipaper solutions platform developed specifically for the paper and cellulose industry, and it can be connected to Siemens process control systems and third-party systems. Environment-friendly solutions for the paper industry are part of Siemens’ environmental portfolio, with which the company generated about €28 billion in sales in fiscal year 2010.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
