What are the approaches for liquefied gas and the deep processing of aromatics? Preparing for the inspection and construction
Thread Content
Our plant plans to build a vacuum distillation unit with a capacity of over 5 million tons per year; after that, we intend to add units for residue hydrogenation and wax oil hydrogenation. What are the advanced processing routes for the liquefied gas (key point) from the above hydrogenation units? What are the processing routes for tail oil? (Priority) Old plant process: atmospheric pressure – catalysis – gas separation – MTBE – ethylbenzene (looking to adopt a better process). What are the possible processing routes for the aromatics obtained from the reformation of vacuum distillate naphtha? Please analyze things based on market demand – making money is what really matters. This post was last edited by mzykater on 2008-6-15 09:35.]
It would be great if anyone could suggest a website or something
http://bbs.hcbbs.com/viewthread.php?tid=6651&highlight=%B7%BC%CC%FE%B9%A4%D1%A7 I’m not very familiar with liquefied gas; the person who is in charge of aromatic hydrocarbon production might want to take a look at this book, as it contains chapters related to advanced processing
The OP’s question is too broad to address clearly at once!
I mean, I’d like to ask Haiyou to recommend a route, preferably with some installation examples. It offers considerable economic benefits and has a wide range of applications
I believe those who work in this field are well aware of the composition of liquefied gas; it mainly contains components such as propylene, propane, n-butylene, isobutylene, butane, butadiene, pentane, and so on. If you want to carry out further processing of liquefied gas, it depends on how well your factory is familiar with the market for these components as well as the derivatives of these components. The old route makes perfect sense; currently there is a large shortage of propylene in the market, and there are also many propylene derivatives ； Propane is in high demand by many steel mills nowadays; it is mainly used for gas cutting and performs better than acetylene ； Butane has few uses; I’m not very familiar with it ； Isobutylene can be used to produce MTBE; the MTBE market has now been reopened and is becoming active again. High-purity isobutylene is obtained through the decomposition of MTBE ； Refracted components such as butane and pentane are mainly used as liquefied gas for vehicles ； Of course, as for other aspects, it depends on the composition of your materials; the composition of liquefied gas varies slightly depending on the properties of the crude oil.
I recommend using carbon tetrahydrocarbon cracking to produce propylene, or C4 aromatization to manufacture triphenyls – the benefits are excellent. For propylene production via carbon tetrahydrocarbon cracking, the raw materials need to have a high content of olefins, while for aromatization the raw materials can be hydrocarbons with a carbon chain length of 3 or more; the higher this value, the better.
Whether it is LPG aromatization or LPG cracking, the most effective component is the olefin fraction within it.
