The final step in linear alkylbenzene distillation creates two major streams: the market specification output and the heavy alkylate bottom. Do You have any idea of the treatment methods adopted for this stream? Do we have any possibility to recover materials from the heavy alkylate bottom...

http://web.baytownsun.com/story.lasso?ewcd=f5b52a50248da15f Probably a failed mixture procedure due to high temperature process in the mixing vessel (o-dichlorobenzene being a solvent of the purified TDI product)...

Would You please explain me what is meant by "augmented offgases"? Are AOGs conceived as thermodestructive machinery mainly, and what is their difference from thermal oxidisers? As far as I know AOGs treat liquid waste and oxidise them with waste heat recovery to the plant service. Thanks in...

Please can You give any additional remarks on the specific section of the explosion, particularly people who know the local situation at Baytown. I suspect it is phosgene, which is highly explosive, but Bayer doesn't cite the storage area, which is the most critical in engineering terms...

Ok. Now I keep them slurries, pumpable, so I eliminate the emulsified oils extracted from spent lubricants, I do not trust their performance once decoupled from their mixed formulated bonds. The problem is transferred down the pipeline to the nozzles and reactor lining; combustion is meant to...

I started a work identifying three different "streams" of oily residuals that can be theorically conditioned by blending and make amenable as feedstock for a pilot gasifier, whose output must be syngas for electricity. Let me know what You guys think of the following: 1) Traditional Bottom Of...

This is just a sample list, however due to strong concentration in the industry the following are nearly synonimous of a specialty segment CRITERION CATALYSTS http://www.criterioncatalysts.com/english/index.htm IFP http://www.ifp.fr/IFP/en/aa.htm, look at "IFP Knowledge Hub" in particular...

I found that lead contractors and licensors websites (Foster Wheeler, UOP, as an example) are very valuable for self-training purposes. Again these could be achieved by consulting operative technical papers on the unit operations You mentioned (desalting, thermal cracking, distillation et cetera)

Orcaa Man this is absolutely not a suggestion on a different chemicals mixing at upstream configuration, but an end-of-pipe suggestion: is it feasible, in the current plant setting, to install a vent network and a thermal oxidation section? Thermal oxidation is maybe the definitive solution to...

Starch cakes arising from filter pressing can be blended for feeding animals, but concentration limits largely depends on national legislation. It should be noted that this residual material is sold and traded on the international market, further suggesting its commercial value at least for...

I understand that capital equipment investment is the major, if not unsustainable, problem to accomodate coking units and inlet pumps to incineration, e.g. for idle refineries. Yet due to the global shortage of refining capacity this is not in the works but, in 20-30 years, a gradual conversion...

I am looking for your scientific advise on the feasibility of feeding flexicoking plants for the destruction of solid wastes, instead of petcoke or heavy oil fractions. I refer in particular to the rationale of producing syngas from slurry, dewatered oily sludge - which are produced in large...

I wrote "oniste" I meant "onsite", that is captive or inside battery limits, sorry.

I made up my opinion that TDI manufacturing is basically one of the most complex processes in the organic base chemistry. Moreover, as I carry out a study on termal oxidation of chemical process scraps for the IT3 conference, I realised the impressive number of ventgases enclosures and routing...

All I know is that it has have been transferred to French group Saint Gobain (in particular to the Advanced Ceramics subholding), which is a major player in refractory lining for APCT equipment. Best regards, Marco

For those out there working on hot rolling mills, oily mill scale coming from oil-water separators is recycled back into blast furnace where it is burned as auxiliary fuel according to a co-incineration principle, under a patent VOEST ALPINE (now Siemens...who else?) technology.
