Questions about hydrogen production operations?
Thread Content
The control of the converter fuel gas is achieved either by controlling the temperature at the furnace outlet or by controlling the temperature at the inlet of the convection chamber. May I ask, Haiyou, which method do you use for control?
Control of furnace outlet temperature, with furnace chamber as a reference; no point shall exceed 980℃
When using natural gas as a raw material for hydrogen production, the inlet temperature is generally not taken into consideration; only the outlet temperature and the highest temperature in the furnace are considered； If hydrogen is produced from dry gas in a refinery, the inlet temperature, outlet temperature, and the maximum temperature in the furnace must be taken into consideration.
Why is it necessary to consider the furnace inlet temperature when producing hydrogen from dry gas?
In dry gas hydrogen production, the feedstock is refinery gas with a complex composition, so there is no need to consider the temperature at the inlet of the converter.
