Innovative Kurita Dropwise Technology for Paper Dryers
The drying process in the paper industry removes water to define the final properties of the product and is one of the most energy-intensive stages of production. Efficiency in the drying section significantly impacts overall economic performance and product quality, with heat transfer conditions in the cylinders being a key factor. These are determined by condensate removal and surface conditions such as corrosion and scaling.
Kurita introduces its patented Dropwise Condensation Technology, part of the CSV Technologies Portfolio. This innovation currently aids over 500 customers worldwide in enhancing productivity and improving heat transfer efficiency in steam condensation systems.
Kurita Dropwise forms a hydrophobic layer that protects steam systems from corrosion and scaling while preventing the formation of a condensate film on condenser tubes. This dropwise condensation effect ensures water droplets flow away from surfaces immediately upon condensation.
Technology Features and Benefits
Kurita DW-1508, a high-tech chemical product, has been specifically tailored to elevate the dryer section in the paper industry. By removing the condensate layer that acts as a barrier to heat transfer, it increases heat flow by up to 30%, delivering measurable benefits such as:
- In multi-cylinder machines, steam savings of 3-10% and a production increase of 5%.
- In corrugating machines and cartoners, a reduction in startup time by up to 50% and steam consumption savings of approximately 8%.
Note: These figures represent average values observed among Kurita customers worldwide. A specific plant evaluation is necessary to determine the precise potential benefits of Kurita Dropwise Condensation Technology.
