C4 Oleflex - Way to Minimize Light Naphtha Export

• In order to maintain the octane of the

gasoline pool; some refineries might

not be able to add all light naphtha

(as isomerate) into the gasoline pool

and some of the naphtha will be

exported.

• Increasing Alkylate and MTBE

production using field butanes will

allow addition of more light naphtha as

isomerate into the gasoline pool. This

can eliminate light naphtha export.

Key Advantages of the Oleflex Process

• Highest Return on Investment (ROI)

‒ Lowest Capital Cost

Small and few reactor vessels

Small process line diameters and small reactor vessels

Small (fewer stages) and simple reactor effluent compressor

Small ISBL Plot Area

‒ Lowest Operating Cost

Low propane consumption throughout catalyst life.

Platinum in the catalyst is recoverable and reusable, avoids disposal costs

Low energy usage

• Smallest Environmental Footprint

‒ Lowest energy usage

‒ Lowest CO2, NOx, SOx, VOC emissions and water usage

‒ Fully recyclable Pt based catalyst. Non-toxic catalyst system

ISOALKYTM - Ionic Liquid Alkylation

UOP 8013B-13 Honeywell Confidential - © 2017 by Honeywell International Inc. All rights reserved.

New Era for an Old Process

Ionic Liquid (IL) Catalysts

• Ionic Liquids are salts that are liquid phase at low temperature

– Typically the anion and cation are both large and the cation has a low degree of symmetry

– These factors reduce the lattice energy of the crystalline form of the salt and lead to a low melting point

• Acidic ionic liquids can have acidity that is orders of magnitude higher than HF or H2SO4

• In contrast to typical liquid acids, ionic liquids are safer to handle

– Vapor pressure near zero

– Thermally stable

Four Distinct Areas

• Feed Treating

• Alky Reactor & Separation

• Product Distillation and Finishing

• Ionic Liquid Catalyst Regeneration

15

UOP 8013B-15

A Better Way to Alkylate

• How ISOALKY Works

‒ Utilizes strong acid function of IL for alkylation reaction

‒ Process design similar to existing alkylation technology

‒ Small, in-situ catalyst regeneration

• ISOALKY Performance

‒ Low catalyst inventory and catalyst consumption 400 times lower

than sulfuric acid alkylation

‒ Improved feed flexibility and performance in C3-C5 range for

maximum upgrade potential

‒ No heavy oil byproduct

‒ Equivalent or better alkylate yield and octane

• ISOALKY achieves equivalent or better economic performance

relative to sulfuric acid alkylation
