Lower steam consumption for processes and saving energy
Large quantities of process steam is required in numerous industrial applications. To achieve this, companies must use considerable amounts for energy. An effective measure to save energy – and to reduce the high consumptions of steam up until now – is the mechanical vapor recompression method, used in evaporation, distillation, crystallization and drying.
The temperature of the resulting process steam (vapor) is increased with a radial fan (mechanical vapor recompressor, MVR), and therefore to a higher energy level, and then fed back into the process as fresh heating steam. The energy contained in the steam is not lost; only the energy required to increase the temperature must be additionally raised.
Mechanical vapor recompression was initially used almost exclusively in the dairy industry. In the following years, its areas of application were expanded, and now include the dairy industry, brewing industry, sugar industry, saline industry, pulp industry, chemical industry, alcohol industry etc.
The high-performance blowers from Piller achieve the necessary temperature increases by means of impeller circumferential speeds of over 300 m/s. Even the impeller geometries are constantly optimized with regard to increasing demands for mechanical strength and efficiency.
