FCC Co-Processing Overview 3 Standard FCC Unit Operation Co-processing RFO in FCC LPG LPG Gasoline Gasoline LCO LCO RFO VGO UCO VGO UCO 100% petroleum based products sent downstream Partially renewable products sent downstream UOP 7214-3 Utilize Existing Refinery Assets & Infrastructure
RTP & FCC Co-Processing Technology Partnership 4 Leading licensor of FCC process technology Supplies basic engineering design for RTP unit Developer of RTP technology Significant technical resources to support refinery post-project implementation Supplies RTP unit with full warrantees and guarantees Developer of projects producing RFO for refiner Contracts with refiner for RFO supply UOP 7214-4
RTP Processing Second Generation Residues to Energy 5 Rapid Thermal Processing biomass conversion to green fuel Energy densification relative to biomass High yield of liquid product (65 75 Wt-% depending on feedstock) Agriculture Residues and Purpose-grown Biomass Fuel Oil Substitution RTP Green Fuel TM Electricity Production Upgrade to Transport Fuels UOP 7214-5 A highly efficient biomass-to-liquid-fuel pathway
RFO Co-processing - Why it Makes Sense 6 Compliance solution controlled by the refiner Utilize existing refinery infrastructure Low oil prices increase cellulosic value Easy to implement Produces renewable gasoline & diesel blendstocks Generate cellulosic RINs at the refinery Produce pipeline-compatible biofuels with existing FCC equipment Eliminate dedicated blending infrastructure without blendwall limits Cellulosic RIN value inversely related to crude prices Minor capital costs for storage & feed injection equipment UOP provides injection equipment & operations assistance UOP 7214-6
Co-Processing Project Pathway RFO produced by outside project developer and delivered to refinery Refiner co-processes RFO with VGO in FCC unit to produce partially renewable fuel blendstocks Refiner generates cellulosic RINs at the refinery based on renewable volume blend 7 RTP Unit RTP Green Fuel (or) Pyrolysis Oil (or) Renewable Fuel Oil (RFO) Refiner co-processes RFO with VGO in FCC unit to produce partially renewable fuel blendstocks RFO produced by outside project developer and delivered to refinery Partially Renewable Fuel to Refinery Pool UOP 7214-7
Co-processing Development 8 Multi-year development program for commercialization Lab and pilot plant testing Proof of concept trial EPA Fuel and Facility registration Two 30 day commercial refinery trials in 1H 2016 Deployment expected in 2H 2016 Current Status Concept Selection Pilot Plant Trial Commercial Injection Design Proof of Concept Commercial Trial EPA Part 79 EPA Part 80 30 Day Commercial Trial Technology Deployment Completed two trials in commercial FCC units In discussion with numerous US refining companies for extended trial in 2016/2017 Currently reviewing multiple refinery partners for commercial trial site UOP 7214-8
Biologically Sourced Feedstocks Characteristics of Concern 9 High oxygen content Acid number typically higher than that found in petroleum Metals higher and different type than found in refinery streams Petroleum: Ni and V Biofeeds: Alkali metals and phosphorus, silicon Chlorides typically present in biological feedstocks some very high Unsaturated hydrocarbons UOP 7214-9
Addressing the Concerns 10 Oxygenates Acid conversion virtually complete in FCC riser Oxygenates in FCC naphtha same as those already seen in petroleum-only FCC operation LCO and heavier cuts no perceptible change in oxygenates Alkali metal effects Studied deactivation at lab scale Economic alkali metal management techniques developed Chlorides Chlorides are possible source of concern in all FCC units Review of operations and equipment before co-processing allows trouble-free operation Unsaturated hydrocarbons Method of operation avoids fouling issues commonly associated with pyrolysis oil at high temperature Commercial proof of concept trial indicated trouble-free injection UOP 7214-10 These measures and others address refiners concerns
