Dear all,
Recently, Hydrogen has become a very promising candidate for the new energy carrier and my company has been looking for a fit and economic H2 production method to the local market. The local market has well-established supply network for natural gas and LPG, so these are main feedstock for H2 production. Myself and the company are very familiar with steam methane reforming technology and its details as we operate several units on our own; however, we know little about LPG(C3 and C4) reforming.
In this regard, I would like to ask the forum to kindly provide general difference between C1 and LPG reformer, and what changes can we expect within the system from C1 to LPG. I have given a thought about changes and they can be the followings. Please correct me if wrong.
1. Desulfurizer : LPG general contains more sulfur contents, so need more catalysts and adsorbents for HDS and ZnO?
2. SR Reactor : For the same amount of H2 production, less LPG molar flow is needed. Reactor size may be reduced?
Do we expect the same GHSV for both C1 and LPG steam reforming reaction?
3. WGS : As CO contents at the downstream of SR reactor would be higher than that of C1, size of WGS reactor may increase?
4. PSA : Just like the reason addressed on item 3, size of PSA may increase?
I may have not addressed enough, so I would like to kindly request the forum to share your thoughts on this topic.
Kind regards,
