CATALYTIC REFORMING
Catalytic reforming is a chemical process used to convert petroleum refinery naphthas, typically having low octane ratings, into high-octane liquid products called reformates which are components of high-octane gasoline
If i need to choose process licensor between UOP and Axens who is better for CCR type according to my criteria:
1. Differences in reformate/hydrogen/light ends yields/RON clearand Utility consumption.
2. Catalyst deactivation and attrition (Catalyst consumption if any ).
3. Side by side versus stacked design.
4. Reduced plot plan area requirement of stacked design ( Equipment size and/or capacity).
5. Ease of maintenance of side by side design.
6. NPV and IIR and Payback and Investment cost (Royalty and engineering fee) ( capex and OPEX if you have any example).

My opinion this is very difficult issue , i hope to solve by experts.

This is indeed a very difficult question to answer without even knowing the type of feed u will be processing,specific process design guidelines and detailed objectives of the unit.There is no definite answer to your question without involving licensor of this technology providing you a tehnical and commercial proposal based on your 'Invitation to Bid' and you performing a NPV calculation on your case and choose one of the two technologies.


replying to your specific questions

1. Differences in reformate/hydrogen/light ends yields/RON clearand Utility consumption.
Answer: Almost similar and the minor difference between the same determines who is going to win your bid.

2. Catalyst deactivation and attrition (Catalyst consumption if any ).
Answer: These are continuous regeneration units and its a pretty robust catalyst ,there can be temporary deactivation due to impurities in feed but overall if operated well the ultimate catalyst life is almost 8 years however the same depends on type of feed and impurities in the feed.

3. Side by side versus stacked design
Answer:Both design work, each having its own pros and cons.Stacked design is prone to pinning of catalyst while side by side configuration may leads to plugging of catalyst transfer lines.
4. Reduced plot plan area requirement of stacked design ( Equipment size and/or capacity)
Answer:Area for stacked design is normally 70% area of side by side configuration.
5. Ease of maintenance of side by side design.
Answer:Nothing specific as such.


6. NPV and IIR and Payback and Investment cost (Royalty and engineering fee) ( capex and OPEX if you have any example).
Answer: i am waiting for someone to give you an example of this !This is a highly classified and confidential piece of information.Refer first few lines of my answer.
