Which unit in oil refining has the most promising future?
Thread Content
Distillation, catalysis, hydrogenation, reforming, coking – which has the greatest potential for development? ? If it comes to learning*, which device is the most difficult and complex?
Catalysis and coking must be the most difficult to learn
Is hydrogenation better for gasoline and diesel refining or cracking?
Lubricant hydrogenation is good; the market is strong.
I want to know too, :D :D :D :D
It seems that anything related to hydrogenation is good – gasoline, diesel, lubricant hydrogenation, and so on. But it feels like this is only part of the product refining process and cannot be considered the main production facility. Nowadays, hydrogenation is shifting from hydrocracking to hydrorefining. The question is whether hydrocracking will eventually be phased out
Hydrocracking is an important method for lightening heavy oil to produce clean fuels, and it also provides raw materials for ethylene cracking. Generally, the hydrocracking unit in a refinery is a quite important unit. Because of the increasing heaviness of crude oil, especially the heavy oils from Venezuela and Sudan, delayed coking plays a very important role.
Personally, I think the prospects for alkylation are good; it enables the production of high-quality gasoline, which is important for the country’s economy and people’s livelihoods. However, the manufacturing process needs to be improved.
The atmospheric and vacuum distillation process is the most difficult to master in terms of catalyst operation; light oil cannot be obtained from this process, and it ends up going into catalytic cracking along with the heavy oil. As a result, catalytic cracking consumes a large amount of space, producing large quantities of liquid hydrocarbons and gas, as well as plenty of sludge. This sludge cannot be utilized on its own, so it is sent back to the atmospheric and vacuum distillation process, creating a vicious cycle that results in significant energy waste. Originally, atmospheric and vacuum distillation was meant to produce light oil, while catalytic cracking was supposed to handle heavy oil. Now, the roles have been reversed – when did catalytic cracking become the main process?
In the refining industry, atmospheric and vacuum distillation are the most profitable processes; a good vs. a poor operation can result in differences of hundreds of millions
It depends on the scale. For ethylene production, the key element is the cracking furnace, which is crucial for manufacturing; in oil refining, the key process is atmospheric and vacuum distillation. At some point, catalysis replaced this process, and those in charge of catalytic processes took control. As a result, it became normal to use oil slurry in atmospheric and vacuum distillation
There are processes such as catalytic cracking and hydrocracking, which fall into this category; there’s also coking. Reforming is relatively more difficult. In terms of future prospects, hydrogenation and the deep processing of light oils hold more promise
Personally, I think it’s hard to say; it depends on future technological developments. Perhaps new technologies or devices will emerge.
Personally, I think it’s catalysis, hydrogenation, reforming; of course, there are also finer distinctions
The teacher said catalysis and hydrogenation.
Hydrocracking, catalytic reforming, hydrofining
