DEAR SIRS, DO ANYBODY KNOW ABOUT USE OF CONTINUOUS PIPE REACTOR FOR HYDROGENATION PROCESS AND CRAKING OF HEAVY OIL CATALITICALLY?ANY SORT OF INFO WILL BE VERY GLAD. BEST REGARD gelpino

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...

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...

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

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...

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

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...

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...

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

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

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

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...

I think are necessary some more info...about solvent and reactor you use.... Regards

Is a little generic question, try to ask with more precision what do you want to know about diesel. :) Best regards

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

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
