Hi,
I am trying to design a flash vessel which reduces the pressure of a stream containing Glucose, Water and dissolved Carbon Dioxide from 240 bar to around 2 bar. The feed has a temperature of 190 Celcius.
I have the following parameters for the feed
Pressure: 240 bar
Temperature: 190 degrees Celcius
Total flow rate: 46000kg/h
Component flow rates: 38,950 kg/h Water ; 4350 kg/h Glucose ; 2700 kg/h Carbon Dioxide
I have calculated the amount of steam that will be produced from the enthalpy to be roughly 43%, so around 16,500kg, and so far assumed that the Carbon Dioxide will come out of solution due to the pressure reduction, as well as assuming that glucose is inert to the pressure reduction. So I know the flow rates of liquid and vapour streams to be 26,700kg/h and 18,300kg/h respectively.
I have done some very basic calculations assuming a binary mixture of water and carbon dioxide.
Although, from here I wasn't sure how to do this design, as I'm not sure if the system being 3 components effects the design as I haven't seen any 3 component flash systems (even though I'm assuming the glucose to be inert and not vapourise). Would I need any phase diagrams to start the design? and what basic principles would be best to start designing this unit?
Many thanks,
Ben
