Would you please share experiences of C4/C5 alkylation?
We are adding C5 alkylation to existing C4 alkylation.
It has a SAR (Sulfuric Acid Regeneration) unit.
Do they usually feed C4 and C5 mixture?
1. Is there any existing unit which is fed C4 and C5 separately?
C5 segregation cause any problem? Licensor says we consume less Sulfuric Acid than mixed feed.
2. With segregated C5 feed, spent acid strength will be 87wt%. Are there any critical reliability issues due to lower spent acid strength?
- reactor corrosion
- spent acid disposal and regeneration unit (SAR)
