Compressed air for blowing PET bottles
Drafting PU01/12/2002
The German firm Boge Kompressoren presented a line of compressed air (FlexPET) specializes in providing air under high pressure to the blowing of PET bottles. It has a wide range of flow rate and reduces energy costs.
Boge Kompressoren is a German manufacturer specializing in air compressors. The company was founded in 1907 and has been providing for years complete supply of compressed air systems: compression, drying, filtering and storage. The Assembly of facilities, their design and engineering are also activities carried out by the German firm.
This experience and knowledge make, Boge has created a new line which has been called Boge FlexPET. The novelty is that this line is specifically designed to provide compressed air under high pressure for the production of PET bottles. The standard product range includes eleven models and a range of effective 93 m3/h at 1,076 m3/h air flow, which covers the most common needs.
The concept is very simple. It is, in a first phase, a compression of low up to 11 bars, produced by a lubricated oil injected screw compressor. This compressor is designed to work efficiently in a range of flow rate from 50 to 100 percent of their maximum load, providing flexibility to the specific needs of air and reducing energy costs. Alternatively, if there are already a compressor for the supply of air network, the installation of this initial compressor is not necessary.
The compressed air is then treated by a dryer of adsorption to a - 40 ° C, a pre and postfiltro dew point and is stored in a warehouse. Air stored in the repository is available, at the moment, both for use in Web applications to low pressure, as for his subsequent compression to high pressure to the process of blowing of PET bottles. This prevents the expansion from 40 to 10 bar, with the loss of energy that this entails (which is approximately 40 per cent).
In a second phase, depending on the required flow, from one to four compressors piston booster rise pressure from baja to 40 bar. Air compressed to 40 bar is stored and dealt with, once again, through Coalescent filters and activated carbon, getting an air quality "technically breathable".
All teams, boosters (compressors), hair dryer, filters and tanks are mounted on a common frame, with all the electrical connections and included air pipes. The electric distribution Cabinet, also mounted on the common bench, incorporates the system of control and regulation of the equipment. This system efficiently controls the operation of each of the teams and, thus, the total consumption of energy of the installation.
The FlexPET line can be configured with total flexibility and does not need anchors on the ground or civil engineering
