HYSYS description:

we selected our components


The fluid packages are chosen ping robinson and amine package
The fluid packages are chosen, ping-Robinson and Amine Package.


Then we added our reaction in reaction tab
Then we added our reaction in reaction tab

Where: Rxn-1: CH4 + 2O2 CO2 + 2H2O

Rxn-2: CH4 + H2O  CO + 3H2

Rxn-3: 3CH4 + 2H2O + CO2 4CO + 8H2



Assumption
Assumption:

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 low level because the removing catalyst is highly sensitive to sulfur poisoning. is consists of Convection section and Radiation section:


The flow rates are: low level because the removing catalyst is highly sensitive to sulfur poisoning.


In heat recovery units are shown below
In heat recovery units are shown below low level because the removing catalyst is highly sensitive to sulfur poisoning.:


Section 200 carbon dioxide separation
Section 200 (Carbon Dioxide Separation) low level because the removing catalyst is highly sensitive to sulfur poisoning.:


Assumptions
Assumptions low level because the removing catalyst is highly sensitive to sulfur poisoning.

  • In section 200, the absorber [C-201] was worked by Amine Pkg as a fluid package because we had MDEA solution, and this column had 95 numbers of stages.

  • We used valve [VLV-100] & [VLV-101] to minimize the pressure.

  • Stripper column [C-203] is actually absorber because in HYSYS there is no stripper column, since Amine Pkg did not work with us we used Peng Roberson Pkg here, and this column had 10 numbers of stages.





Assumption1
Assumption water.

  • We modified this section as follow:

    - 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.


Thank You water.
