Alkylation Technology
Consultant/Trainer: Rick Rhead
The Petrogenium. Alkylation Technology course will guide the participants to develop key concepts on overview of design and operating parameters of Alkylation technology. This training provides an understanding of Alkylation process, different technologies and operating and safety concerns.
Participants
This Petrogenium. course aims at improving competencies of process engineers, operators, inspection and corrosion engineers in terms of understanding the process and operational issues faced by complex refineries. It is also possible to benefit from an exclusive technical services arrangement from Petrogenium after the training. Participants can be from diverse spectrum of both young and experienced engineers. The training can also be structured to address specific issues faced by a particular refinery / operating unit.

Day 1 Afternoon
Introduction
Sulfuric Acid Alkylation
- Block Flow Diagram
- Pretreatment Section
- Typical operating conditions: iso-olefin and Acid/HC ratios and temperature
- External acid regeneration—purge & fresh make up (trailers of spent/fresh acid—daily)
- Sulfuric acid suppliers (typically will also handle the spent and fresh acid)
Product Treatment
Better Technology
- HF Alkylation is slightly better: RON, Yield, Utilities
- Sulfuric Acid is safer and HF Alkylation has “NIMBY” concerns
- Politics beat Technology
- Solid Bed Alkylation
- Ionic Liquid Alkylation
- Commercialized technology (Chevron-Salt Lake City, USA)
- Solid Bed Alkylation
- Ionic Liquid Alkylation
- Commercialized technology (Chevron-Salt Lake City, USA)
- Liquid ionic catalyst (Aluminum-Chloride)
- Similar to HF Alkylation—Block Diagram
- Similar to HF Alkylation
- Reactor
- Effluent Separator
IsoAlky Fractionation
IsoAlky Product treating
IsoAlky Operating Conditions
- Wide range of operating temperatures
- Less likely for “acid” runaway
- Lower utility costs
- No special materials of construction
- Better suited for alkylation of Amylenes
- Off loading spent acid/loading fresh acid, and acid sampling
