Discussion on the residue hydrogen production process!
Thread Content
Hello, everyone! Could any experts explain the process of producing hydrogen from residue oil? The main process flow, the cost of hydrogen production/M3, and the challenges in operation. . .
Hydrogen production from residue oil? ? I’m hearing this for the first time: residual oil has a high sulfur content, which places a heavy burden on the hydrodesulfurization process. Is it similar to hydrogen production from coal, where CO and hydrogen are generated first, followed by desulfurization before entering the temperature-controlled reactor? ?
I heard that Shell has advanced technologies, and I’m very much looking forward to it! ! !
The sludge gasification processes mainly include those developed by Shell and Texaco; both of these companies have now been acquired by AP, resulting in a single entity. The entire process consists of gasification + low-temperature methanol washing + shift reaction; purification can be carried out using PSA or methanation thereafter. The difficulty in operation lies in long-term operation.
I published a paper in February 2021 on the economic feasibility of POX hydrogen production based on the re-gasification of heavy oils and gases; you can search for it on CNKI by yourself.
To produce hydrogen, one uses a gasification furnace; subsequent steps include conversion, low-temperature methanol washing for desulfurization and decarbonization, methanation, and PSA purification. The challenge lies in the fact that the gasification furnace needs to be shut down every 7 to 8 days and cannot operate continuously.
The main bottleneck in hydrogen production via gasification lies in the long-term operation of the equipment
There is no issue with the long operational cycle of the equipment; you can search on CNKI for a paper I published in January 2021, titled \"Summary of the Operation of the Shell Heavy Oil Gasification Unit\"
Since I’m just starting out, could you explain it in detail?
