Does the use of fluidized-bed hydrogenation technology mean that there will be no coking units?
Thread Content
Is this technology currently in use? What are the raw materials, and what are the products? Could you provide a comparison between the traditional hydrogenation technique and the current fluidized-bed hydrogenation method?
It’s not available in the domestic market yet; mainly, it’s diesel, gasoline, liquefied gas, etc., along with wax oil
Go and take a look at the official website of Shanghai Xinyou Energy
Shenhua’s Fei-Teng bed hydrogenation system has been in operation for many years, using French AXENS technology
The two largest fluidized-bed hydrogenation units in China and even in the world are expected to be built at Hengli Petrochemical by the end of 2018. Utilizing French AXENS technology, these units have a residue conversion rate of around 85%; it will be necessary to assess their efficiency, safety, and stability through operational testing!
In China, the only truly industrialized fluidized-bed hydrogenation plant is that owned by Hebei Xinqiyuan; it is said to be operating well
What has been newly introduced is a suspended-bed reactor, but it is not a hydrogenation unit for petroleum-based residue in the true sense.
Considering the conversion rate and subsequent processing methods, there is always some residue oil that cannot be converted in a fluidized bed; in such cases, coking or propane deasphalting can be used for treatment.
The equipment for Xinqiyuan was designed by us, and I can assure you that it is indeed a fluidized bed. We are currently upgrading it, increasing its capacity from 150,000 tons to 250,000 tons
