Process flow with a water vapor ratio of 0.8 at the inlet of the conversion unit, and effective gas volume at full load
Thread Content
For the Dashiemen unit, regarding the water vapor ratio at the gasification outlet and the requirement that CO levels at the full conversion outlet be less than 1.0%, should an adiabatic + isothermal furnace or a dual-adiabatic furnace be used in the conversion process? What is the approximate effective gas handling capacity? What is the approximate catalyst loading amount? Thank you
In the design of the conversion unit, it is necessary to take into account both the required level of CO in the outlet gas and the energy consumption and economic efficiency of the process. Based on the inlet water vapor ratio of 0.8 you provided and the requirement that the outlet CO level be less than 1.0%, a process using an adiabatic + isothermal furnace is generally recommended. The combination of an adiabatic and isothermal furnace can improve conversion efficiency while controlling the CO content at the outlet. First, the adiabatic furnace carries out preliminary CO conversion, and then the isothermal furnace further reduces the CO content to meet the requirement that the CO level at the outlet be less than 1.0%. The effective gas volume for treatment and the catalyst loading depend on specific design parameters and process conditions, such as gas flow rate, pressure, temperature, etc. Without these detailed figures, it is impossible to provide an exact number. These data usually need to be obtained through detailed engineering calculations and simulations. It is recommended to work with professional engineers or technical teams for detailed design and calculations. .
The choice of that approach depends on the front-end gasification method and gas volume
