Hello All:
I have a Glass vacuum trap that is immersed in a liquid nitrogen dewar. I am interested in the vapors that are condensed inside the trap. This trap is in line with a vacuum pump that generates 1.5 torr of vacuum.
The problem is I am not able to disconnect the body of the trap from...
Hello:
Can anyone suggest where I could buy cold trap that can be used for pervaporation (lab scale) unit. I will be using it for condensing vapors of ethanol/water.
Thanks in advance

Dear All:
I am working on a bench scale pervaporation unit, directed towards separating water from ethanol using a polymer dehydration membrane.
As of now, I am having extreme difficulty in collecting all the permeate vapors and condensing it. Although my experimental time is long enough...
Dear All:
1) Does upstream pressure have any effect on pervaporation flux?
2) Will higher upstream pressure create higher driving force ?
Please let me know your suggestions.
Thanks

hi
I am in need of data for ethanol that relates concentration (% v/v) and density at various temperatures. I have looked into Chemical engineering hand book, they have the density data at wt%.
If anyone can suggest any reference material to get density data for ethanol concentrations in % v/v...
Hello:
I have a process that generates ethanol concentration varying from (90 to 98 % v/v). I would like to recycle this i.e., to use it at lower concentrations such as 80,70 % v/v etc. Can any one suggest suitable procedure to achieve this such that the purity of ethanol is retained. My...
Hello,
I have few questions related to pervaporation process.
1)Can pervaporation experiments be conducted at isothermal process? If so how?
2) I am using a polymeric membrane to separate water from alcohol at a temperature of 60C. But during the process of experiments the temperature rises...
