Semi-coke gasification unit
Thread Content
What are the existing semi-coke gasification units? The increase in future projects will result in a shortage of gas for our company. The management wants to pursue this project; we would appreciate your advice!
Coke is widely used in atmospheric furnaces; the Ruhr process involves the gasification of semi-coke. It mainly depends on the properties of your semi-coke to choose the type of furnace
Thank you, friend. May I ask where I can find information on some domestic devices? Or books would work too. I have no idea at the moment; I don’t know how to find out about market conditions!
It can be said that coke has been used in atmospheric-pressure furnaces for a long time and on a wide scale. An application in pressurized gasification furnaces was demonstrated recently through a trial burn of coke from a company in Ningxia. Theoretically, the upper focal zone has better activity and is easier to vaporize.
Okay, thank you, my friend. I’ll have to turn to you for advice if I have any more questions in the future
Particle semi-coke should be gasified in a fixed-bed (moving-bed) reactor for the best results.
Oh, I see. Do you know of any company projects, friend?
We can do this, and by using the same carbon source and the same manufacturing process to produce fuel gas, its calorific value is increased by 10% compared to conventional gas； The carbon content in the slag is reduced by 10% ； Operating power consumption reduced by 20% ； At the same time, oxygen-deficient sulfur fixation can be employed to significantly reduce the sulfur content in coal gas.
I would like to understand the principle behind reducing sulfur in gas, as you mentioned
The carbon molecule vaporization and combustion technology, which serves to prevent pollution at its source, involves adding desulfurizing agents to the gasified coal; sulfur is then removed under oxygen-deficient conditions in the gasification furnace, thereby reducing the sulfur content in the gas (this can be determined based on local environmental standards). This process changes the governance concept of existing technologies.
Is the sulfur in coal present in the ash? ! How should such vaporized ash be disposed of?
