    Refining process units monitoring

    I think that the answer to your question is more or less one thousand of paramters. MAy be that you must specify the question

    Hydrotreater - cost of +1 deg inlet temp

    I suggest to do the following: the heat duty that you have to give to the feed is: feed flow rate (kg/h)*specific heat (kca/kg°C)*temperature difference (°C). In your case the temperature difference is 1°C. In this way you calculate X kcal/h that you must provide. I assume that this X must be...

    VOC absorption

    I am talking about hydrophobic VOC such as benzene. For state of art I mean "used technology for VOC absorption". I want to reduce to a concentration that complies with the law

    VOC absorption

    Hi all, I want to know the state of art on VOC absorption. Can someone give me detailed information on existing facilities where the VOCs are removed with an absorption tower (and the absorbent liquid is regenrated with a stripper)? Thanks all!

    Toluene-Water system in Aspen

    i want to insert the solubility data of toluene in the solution of water and copolymer, so, because the copolymer is about 2 % (w/w), I can approssimate the solution to pure water but I must change the water solubility of toluene and set the solubility of toluene in water+copolymer; so I created...

    Toluene-Water system in Aspen

    Forum I have a problem. I created a pseudo-toluene. For the pseudo-Toluene I inserted the true data except the data of water solubility because I inserted the solubility of Toluene in the solution water-copolymer. The problem is that Aspen seems not to use the data I inserted, in fact the...

    Toluene-Water system in Aspen

    Mike thanks a lot for your answer. There are news. With Aspen Properties I found a property method that appears to be suitable for water-toluene: UNIFAC (or UNIQUAC) + free water calculations. But it is clear that I can not use the free water calculation if I want to do an absorber column, so I...

    Toluene-Water system in Aspen

    Hi all, I am Eng.Antonio Aulicino (University Federico II of Naples, Italy). I am using Aspen Properties to understand what is the suitable property method for a system with toluene and water. I do the Txy diagram and xy diagram, but i didn't found a property method that gives results in...
