Deep processing of washing oil
Thread Content
Dear sea industry peers, how is the development of oil washing and deep processing projects in China at present? What products do domestic companies usually extract from this project? Is there a high demand for these products? Were indole, quinoline, acenaphthene, fluorene, and the like also extracted separately, just like foreign companies do?
It depends on the level of the enterprise and its scale of operation; most small and medium-sized enterprises hardly carry out any further processing of the refined oil, instead selling it as the final product in order to achieve economic benefits. However, large and medium-sized state-owned coking enterprises all carry out deep processing. Moreover, the vast majority of companies make corresponding adjustments in response to market changes and customer needs.
Industrial naphthene, α-methylnaphthalene, and β-methylnaphthalene can be extracted.
Deep processing of washing oil generally yields methylnaphthalene, acenaphthene, fluorene, as well as quinoline. After the production of methylnaphthalene, acid-base washing is carried out to remove quinoline; the washed fraction can then be further processed and separated into a-methylnaphthalene and b-methylnaphthalene. The boiling points of a-methylnaphthalene and b-methylnaphthalene differ by 3°C under normal temperature and pressure; therefore, conventional continuous distillation can achieve at most 96% purity, and many plants are unable to reach this level. To obtain a purity of over 98%, azeotropic distillation is generally used.
It is profitable if 2-methylnaphthalene and industrial acenaphthene can be produced
Well done; it would be even better to mention two more names, as many people are researching this
Here, through the deep processing of 30,000 tons of washed oil, it is possible to extract mixed methylnaphthalenes, industrial naphthenes, light washed oil, fluorenes, oxofluorenes, heavy washed oil, naphthalene fractions, and 1-methylnaphthalene. Products such as 2-methylnaphthalene, quinoline, isoquinoline, and trimethylpyridine!
The friends upstairs are really impressive; what level can you achieve in terms of 2-methylnaphthalene content, and what is the yield?
That’s amazing; I’m learning materials on *this topic! ! ! !
Our requirement is that the 2-methylnaphthalene content must be over 95% to be considered qualified
Reply to 7# shandong888: Are these products selling well right now? Has a lot of it been exported?
