Hi,

My name is Maria, I am a Chemical Engineer.
I am interested in colecting information pertaining CYCLOHEXANONE.

We have a process in our Company, and the information I am doing
research on is a Process and how it affects human health.

This is the information I have up to now.

Cyclohexanone
Evap rate = 0.29
Vapor Pressure = 5 mm Hg a @21 C

In our process we use a Felt that is injected with Cyclohexanone
The area of this felt is

Length = 3 cm
Width = .5 cm

Cyclohexanone is continualy flowing by gravity, it has a regulated flow
and it only has 6 seconds to recharge 4 molds.

For any answers I am very apreciative.

Dear Maria,

How is the felt connected to the molds? Are you asking for the flow
rate that will keep the felt saturated despite evaporation? Do you have
a picture you can refer us to? (Please don't post the actual picture to
this non-binary newsgroup.)

Would you like to know the evaporation rate from the area 3 x 0.5 = 1.5
cm^2 at 21 deg C? What are the units of your evaporation rate of 0.29?
Might they be g/sec? Whew! That's volatile stuff!
