Hi all
I've got a quick question I'm hoping some one can help me with.
I'm currently working on a project with a VOC recovery system.
Basically the system consists of a compressor and various shell&plate heat exchangers and it will be used to "recover" VOC from a crude oil carrier during loading.
VOC is a hydrocarbon gas mixture consisting of 13 different components, ranging from methane to n-Heptane also including O2, N2, CO2 and H2O.
The part I'm working on is a unit including the compressor, 1st stage VOC condenser and a separator to separate the liquified components. The 1st stage will only liquify some of the heavy components.
Here is what I need some help for. I'm assesing the heat exchanger which has been calculated by a vendor.
To asses the calculation from the vendor I've made a simple hand calculation, where I've derived the individual components partial pressure. The partial pressure is based on the molfraction which we have been informed by our client.
Now I've simply found boiling temperature for each component at the specific partial pressure in order to identify which component will be liquified. Then I've summarized that to get the total liquid flow.
My question is now, can I use this approach do a simple check of the heatexchanger calculation.
Best regards
Sebastian
