Can atmospheric-pressure furnace gasification produce residue oil
Thread Content
Dear teachers: In the books, UGI and Lurgi reactors were used for gasifying coal. Can such atmospheric-pressure gasification reactors now be used with residue as the feedstock? There is a project currently under consideration, and residue is quite cheap; I would like to know whether this is feasible
It probably won’t work; fixed-bed reactors use lump coal, which has a high content of residue and water, as well as uneven particle sizes.
No, there are requirements regarding the raw materials; if residue oil is used, technical modifications are necessary
You use residue oil as raw material to produce gas – what for? Is it ordinary fuel gas or feed gas?
The Texaco water-coal slurry gasifier works well; fixed-bed gasifiers have requirements regarding slagging tendency, cohesion, and particle size, and they are more difficult to operate
Fuel oil is used as the fuel gas to power the heating furnace, but since approval for using coal locally could not be obtained, and considering that the cost of Texaco’s water-coal slurry gasification furnaces is high while those of atmospheric-pressure furnaces is low, this solution was devised
This can only be achieved using current fluidized-bed gasification; for example, the raw material used in the earliest Texaco gasification processes was residue, and these are all very mature technologies.
If it is fuel gas, a carbon molecular vaporizer can solve your problem. Its production cost is lower than that of Texaco, similar to that of current two-stage furnaces.
May I ask which companies can provide the process technology and equipment for carbon molecular vaporizers used in gasifying residue oil? Could you please provide their contact information?
Fixed-bed gasification isn’t a viable option; it has high requirements regarding the raw materials used. Coal water slurry gasification could be considered, as Texaco certainly started out using residue oil.
