Section 100:(Steam reforming and Heat recovery section)
Section 200 (Carbon Dioxide Separation)
Section 300 (Hydrogen Skimming)
we selected our components
Where: Rxn-1: CH4 + 2O2 CO2 + 2H2O
Rxn-2: CH4 + H2O CO + 3H2
Rxn-3: 3CH4 + 2H2O + CO2 4CO + 8H2
1- In section 100, we replaced the H2S Adsorber with component splitter [C-101A&B] because in HYSYS there is no adsorber column.
2- We used two reactors for steam reformer, one worked as conversion reactor where combustion reaction [Rxn-1] take place then we used the heat produced from it as a heat input for the second reactor which was equilibrium reactor where our man reactions take place [Rxn-2,Rxn-3].
3- We used coolers [E-104.] and [E-110] because we had a temperature cross problem.
4- We did compressor [K-103] in two stages, in the first stage (Recy CO2 stream) was mixed in mixer [Mix-101]. And in the second stage (water3 stream) where recycled to mixer [Mix-101].
It’s necessary to remove sulfur components down to such low level because the removing catalyst is highly sensitive to sulfur poisoning.
The flow rate was:
Steam Reforming is consists of Convection section and Radiation section:
The flow rates are:
Section 300 (Hydrogen Skimming):
- We used two flash columns , one acted as demister to absorb the liquid , the other one [V-104] acted as separator to separate the liquid from the vapor.
- We replaced the membrane [ prism separator ] in actual design with component splitter [ X-101 ] in our design to get the final product.
