MVR Process
In this case the energy input to the system lies in the pumping energy of the compressor. The theoretical energy consumption will be equal to, where
- E is the total theoretical pumping energy
- Q is the mass of vapors passing through the compressor
- H1, H2 are the total heat content of unit mass of vapors, respectively upstream and downstream the compressor.
In SI units, these are respectively measured in kJ, kg and kJ/kg. This theoretical value shall be increased by the efficiency, usually in the order of 30 to 60%. In a large unit, the compression energy is between 35 and 45 kW per metric ton of compressed vapors.

Famous quotes containing the word process:
“At last a vision has been vouchsafed to us of our life as a whole. We see the bad with the good.... With this vision we approach new affairs. Our duty is to cleanse, to reconsider, to restore, to correct the evil without impairing the good, to purify and humanize every process of our common life, without weakening or sentimentalizing it.”
—Woodrow Wilson (1856–1924)
