MVR compressor
Thread Content
What is the current compression ratio range for MVR steam compressors? What is the lowest operating temperature for low-temperature MVR? Low temperature indicates that the MVR operates under negative pressure. What is the maximum vacuum level that the MVR can achieve? Can it be reached?
Now, taking into account the service life of the impeller, the pressure ratio is not set too high; it is generally kept below 2. As for low temperatures, it depends on the properties of the material being processed – there’s no need to pursue extremely low temperatures. At our company, the lowest temperature achieved so far is 50 degrees. 2.30 degrees is also acceptable; however, the equipment cost is very high and the volumetric flow rate is extremely large
A pressure ratio of 4 can be achieved with a single-stage, two-stage design
Can a compressor achieve such a high level of vacuum?
The evaporation temperature in existing operational cases is around 60 degrees. MVR low-temperature evaporation is primarily used for heat-sensitive materials; however, the volume flow rate is relatively high, which results in larger separators and corresponding pipelines. As a consequence, the steam compressor housing and impeller become larger, while the motor power remains relatively low. As for the vacuum level, it is related to and corresponds to the temperature of your evaporating liquid phase, its boiling point, as well as the temperature of the gas phase. In the case of evaporation at low temperatures, maintaining an appropriate vacuum level is crucial for ensuring the stable and proper operation of the system.
What is the steam pressure at 60 degrees? Can the compressor guarantee it?
As long as the MVR inlet/outlet temperatures meet the requirements, there is no need to strive for excessively low temperatures
Some materials must be handled at low temperatures!
At what temperatures, pressures at the inlet and outlet of the MVR compressor is it no longer necessary to supply fresh steam?
During operation, fresh steam is required, but only in small amounts!
