Hi,
I need to calculate the vacuum requirement for a 100 L vessel used for boiling a solvent (DMSO). The vessel is to operate under 0.2 bar. The jacketed vessel will be heated using a oil heater (~20 kW). The solvent will boil at 100 C at that pressure. The evaporation rate will be ~0.6 mol/s.
I have done a simple ideal gas equation, however it doesn't look right to me:
Volumetric flow rate = (0.6 (mol/s) x 0.08314 (bar L/mol.K) x 373 (K))/0.2 bar = 93 L/s
Based on the above I will require a vacuum pump with a capacity of 5580 LPM which seems quite high.
Let me know if more information is required.
Thank you in advance.
