    hybrid membrane/absorption compact system

    Hy I refer to system in wich you have for example a reformed gas but not only(H2,CO2,CO,H2S,HCl,CH4,...) and you want to absorb for example H2S and CO2 using some fluids as amine or other but after this have flow through a membrane...to have a system with smaller size (compact)....have anybody...

    H2SO4 production in refinery

    Thanks for your attention, about trasport it may be (perhaps i mistake?)the same situation for sulphur...that costs here about 50 dollar/ton and are going down making it not a commodity but almost a true cost. So the interest on this matter. It would be interesting to know the name of some...

    H2SO4 production in refinery

    Hy all, anyone know if in some refinery (or also in oil or coal consuming power plant) there is experiences on production of sulphuric acid instead of sulphur?It would be so a bad idea? Thanks in advance. Best regards gelpino

    hybrid membrane/absorption compact system

    Hy all, i'm interesting in processes regarding COMPACT absorption systems useful to purify a gas stream, to extract some polluttant with for example some hybrid system membrane/absorber. Anyone know something about this kind of systems? Any information or idea also about other compact cleaning...

    relation between pen & viscosity

    yes but if we bland vacuum residue with HVGO...of different crude (or bland of crude and fuel oil foer example)i think the situation is quite different gelpino

    relation between pen & viscosity

    I have found a relation from an old work of "R.J. Saal" and another of Abushlhada (Ind.Eng. Chem. Prod. Res. Dev., Vol 18, No 4, 1979)in wich there are some relation penetration viscosity of asphalt. Similar to V=[(1,59*10^10)/P^2.16] for purely viscous asphalts (Newtonian)in agree...

    model reliability

    hy folk, i'm intersting in knowing how to assess reliability of a model. For example if I have a set of experimental data I can find some correlation (polynomial or other) to approximate these. which parameter i can use to evaluate if model is good or not? Excell give "R^2" and I...

    relation between pen & viscosity

    Thanks a lot, If u want share documents plz send to gelpino@yahoo.it. Surely it would be interesting to find that shell paper or some similar reference. At this point I wish at least to know about theories useful for this study. Everything is glad. Best regards gelpino

    relation between pen & viscosity

    I point out that our problem is that having the VBN of an heavy blending we want to know the penetration of residue becouse at present our empirical relation is not good for all the oil we use in our refinery. I would glad any info about this. Best regards. gelpino

    sulphur asphalt/bitumen

    I'm interesting to have info about sulfur asphalt (or sulfur extended asphalt or bitumen sulfur modified and so on). How is the present situation? What about emissions concern?What about possible co-additive. Thanks a lot for any info. best regards

    relation between pen & viscosity

    Hi, there's someone that can explain me something about blending,recutting, "viscosity blending number"(VBN) and evenctually if there's some kind of relation similar to "penetration=f(VBN,?)"or some info related to it? Thanks a lot also for reply to a part of this long...

    Scrubbing Vacuum Tower Vent Gas/Safety Concerns of Air Intrusion

    to travitch Try also to contact www.hijet.com...it's possible they have good news for you....but i'm not sure [atom]

    Scrubbing Vacuum Tower Vent Gas/Safety Concerns of Air Intrusion

    It's also possible to think about a liquid ejector in wich the liquid can be for example the amine. I know some firm that product this kind of ejectors in different sizes and with different feed liquids. Best regards
