Vapor Pressure of Hydrocarbon Condensate?

10/15/2007 9:09 AM

Hi folks,

Could anyone out there help me with the Vapor pressure of Condensate (Hydrocarbon) at 25 deg. c.

Also let me know how to locate such information/data on the Net.

Regards,

At 25degC the vapour pressure of diethyl ether is much greater than that for cetane.

So which hydrocarbon condensate does this post refer to, or is it a mixture? It looks like a textbook on fractional distillation is required.

Depending on the hydrocarbon mixture, there will be several vapor pressures. Follow PWSlack's advice and buy, beg, borrow or ste...,(no don't steal!) a petroleum text, fractional distillation guide, or a thick chemistry handbook. Each hydrocarbon in your mix will have a different temperature. Different regions of the world have different mixtures of hydrocarbons, so there is not an average number to use.

Recommend Nelson's text "Petroleum Refinery Engineering" (McGraw -Hill) as a starting point.

Could it be refrigerant data that you are looking for .. ?

More info required

A re-tread of other posts but we need to know what is in the condensate in order to give you an answer.

You need to know the composition of the condensate in order to determine the vapor pressure.

The vapor pressure then becomes the sum of mol% X the psuedo critical pressure for each component.

Get a copy of the GPSA data book see section 23-11. Anyone working in the gas plant industry should have one.
