hi friends,

       i am working TiO2 production plant by sulphate method, now i am n the
digestor section(ilmenite reaction with sulfuric acid) i have more prblm on the
mass formation. if u have any suggestion to reduce mass formation and the
parameter which r affect digestion pls reply me.

thank u 2 all,

Hi guys!!

I am a student and I am on the process of having an equipment design for
evaporation system under vacuum. The design will be used to concentrate sugar by
an evaporation system under vacuum. Part of the design is the design of a direct
contact barometric condenser. I have already a book of Hugot but I find it
incomplete for the detailed design of the condenser specially on the design of
the baffles, heat transfer coefficient, etc.
Anyone can suggest or give me a reference material on the design of the
barometric column? It would be a great help to me on my studies

Thanks..

you can email me at sqbarroga@gmail. com

Usually one can perform a weighted mass average of density, unless one
expects non-ideal mixing. Viscosity is often not directly averaged.
Consult "The Properties of Gases and Liquids" by Bruce E. Poling (Author),
John M. Prausnitz (Author), John O'Connell (Author) for mixing rules.

hi guyes!
i have done several practical to chemically recycle the PET.
And also i have analysed the final product get from it. I did several FTIR test.
But i have not find the correct Graph for compare the product.

Subject: [che-comp] Re: Calculation of density for a mixed phase stream

Good day!

I'm required to calculate the density and viscosity of a mixed (liquid +
gas) phase. The gas and liquid phase are mixed and comes out as a mixed
phase. I'm given the density, viscosity, mass flowrate, and volumetric
flowrate of the individual phases. I need to find the density of the mixed
stream. Is it right to add the masses of the gas and liquid and divide it by
the added volumetric flowrate of the mixed stream? I find this method too
simple. It is also questionable because the volume portion of the stream may
not be additive. The mass values may be added, but volume, i'm not so sure.
If you have any reference or more accurate method for calculating the
properties of the mixture, i'd be glad to hear of it.

Thank you.

(2) Conversion of sulfur trioxide, (3) Absorption of sulfur trioxide are
heterogenous reactions. If anyone can suggest any book, I'd appreciate it. Thank
