Executive Summary (1/4)
Concawe Sources: OECD
PFAS are a large group of substances, both polymeric and non-polymeric, containing carbonfluorine bonds (C-F) which are considered the strongest in organic chemistry, resisting heavily to degradation.
OECD lists around 5000* PFAS which are scientifically referenced by their chemical structure category name (e.g., polytetrafluoroethylene), but better known by industrials by their abbreviations (e.g., PTFE) or brand name (e.g., Teflon).
As the refining sector does not produce PFAS, the majority of these substances are found in solid form (mainly fluoropolymers), contained in industrial equipment, representing a small portion (~5%) of the total diverse portfolio of PFAS and with low risk of exposure during operation.
PFAS show a unique combination of resistance to the extremely high temperatures, pressure and corrosive environments needed in refineries, as well as resistance to combustion and leakage required in fuel distribution, which are critical to ensure the safety of operations
This report aims to provide an overview of the use of PFAS in the industrial equipment of refineries and fuel distribution today, potential alternatives to PFAS, current waste & emission management plans and the impact of a restriction of PFAS use in the refining and fuel distribution in Europe, based on an industry survey covering 52 refineries and around 11,900 fuel distribution sites in Europe, as well as advanced analytics methods such as text mining & patent analysis.

Executive Summary (2/4)
Concawe
Today, even major refineries do not have a complete inventory of PFAS within their equipment and have difficulties to obtain this data for the following reasons: (i) limited information from suppliers on equipment materials, (ii) presence of legacy equipment predating the awareness about PFAS components (e.g., equipment dating up to 50 years), and (iii) primary focus on performance of equipment rather than composition.
The industry survey and advanced analytics methods have shown that, although the set of PFAS used in the refining industry is limited to around 50 molecules, their use is vital and widespread across all core equipment for most companies.
The main PFAS used in refineries are fluoropolymers, but other liquid and gaseous molecules are also present. PFAS are used as plastics and elastomers, lubricants and coatings, which are present in plant safety equipment, compressors and agitators, but also in indispensable and ever-present equipment across plants such as gaskets and sealings, pumps, valves and accessories, making the use of PFAS vital and widespread across all core equipment for most companies.
PFAS are mostly used in refining equipment due to their (i) chemical resistance to a very corrosive environment, (ii) thermal resistance, with wide operating temperature range and nonflammability, (iii) strong mechanical properties, such as resistance to pressure and high tensile strength. Use of PFAS in fuel distribution equipment is mostly driven by resistance to corrosion and combustion, reduced risk of leakage and enhanced safety performance.

Executive Summary (3/4)
Concawe
Although waste and emission management plans dedicated to PFAS-containing equipment today are limited, most refineries in our study are developing some type of management plans for PFAS (health & safety, environment & emission or waste management plans), mostly related to wastewater management.
Refineries and equipment suppliers have started investigating alternatives to PFAS materials providing similar properties (e.g., thermal and mechanical resistance). However, there is a lack of potential replacements capable of ensuring required levels of operational efficiency and safety.
Technical alternatives to PFAS exist for limited materials and use cases, in the form of replacement of fluoropolymers by other polymers, specialty metals, other materials (e.g., glass, ceramics, ...) or of non-fluorinated gases for refrigerants.
In particular, the industry has identified some potential substitutes for the following PFAS equipment applicable only for specific use cases:
Joints: metallic (nickel), graphite, organic/mineral fibers Piping: thermoplastics, Hastelloy, glass lining, nickel, titanium Valves: polyethylene, Hastelloy, EPDM, Vespel Refrigerant gas: ammonia, CO2, propane/isobutane/butane Coating: PPV, epoxy, polyester, melamine

Executive Summary (4/4)
Concawe
However, alternatives often do not match all the properties of PFAS and have other drawbacks: Safety of the future installations yet to be demonstrated Long alternative development process Production tools and supply chain adaptation to cope with sharply increased volumes Possible same persistence characteristic of alternative materials Some identified alternatives containing traces of PFAS (voluntarily or involuntarily)
Many challenges have been identified with a ban of PFAS in industrial equipment: No known alternatives to date for some equipment and unfavorable performance of alternatives identified Substantial impact on direct costs (maintenance) and impact on utilization (more frequent failure/maintenance activities) High complexity to transform plants linked to the use of PFAS Potential impact across the energy value chain in Europe, putting at risk supply and access to fuels due to simultaneous closing of multiple refineries and fuel distribution sites

Challenges in PFAS Inventory
Identifying PFAS in refining plants is a challenge for many players in the refining and fuel distribution segments
Challenges in data acquisition
Widespread presence of various PFAS in many equipment
Primary focus on functional specification, compliance & safety
Engineering and maintenance responsibilities often lie within external parties
Suppliers have limited awareness of the existence of PFAS in products especially if they are distributors of equipment and not original manufacturers
Legacy equipment predating the awareness for PFAS components (e.g., equipment dating up to 50 years)
Use of assembled and packaged equipment with limited information of each internal component
PFAS are used in a wide range of applications present in multiple equipment such as:
Pumps (Coating and Gaskets)
Valves (Body, Washers and Gaskets)
Gaskets and Sealing
Pipes
Equipment and material selection prioritize functional specification such as temperature, pressure and chemical compatibility requirements over PFAS presence
Regulatory teams primarily concentrate on assessing the compliance and safety of raw materials and additives used in final products

Refinery & Fuel Distribution Requirements
Fluoropolymers in particular show multiple resistance properties which make them the most used type of PFAS
Refinery Requirements
Chemical Properties
High resistance to corrosion: Resistance to aggressive products (pH<1) such as nitric acid and chloride acid
Chemical inertia: Material that degrades little over time, little product contamination (i.e., no impurities)
Resistance to permeation and capacity to prevent migration of gases, liquids, and chemicals through material (e.g., leakage)
Thermal Properties
Wide operating temperature range: As example, PTFE has a permissible temperature range of [-20 to +260] C and can withstand high temperatures without degradation
Mechanical Properties
Resistance to pressure: Some refining processes require high pressure
High tensile strength: Can withstand mechanical stress and deformation
Low friction coefficient: Non-stick and lubricants properties
Fuel Distribution Requirements
High resistance to corrosion: Resistance to fuels with high percentage of aromatics, npentane etc.
High resistance to combustion: Nonflammability and resistance to burning when exposed to a flame or ignition source
High resistance to ageing and drying to avoid change in hardness, elongation at break and mass reduction from original values
Flexibility for various requirements: In many cases, exact resistance requirements are not clearly defined (i.e., not all corrosive elements are known) and suppliers opt to use PFAS knowing of their resistance to a wide range of chemicals and conditions

Majority of plans are around wastewater management Plans are typically driven by local or national regulations Limited PFAS categories are concerned, such as refrigerant and
firefighting foams
Example of Driving Regulations
European regulation on persistent organic pollutants (POPs): Defines measure of around 20 PFAS types in waste When detected above limits, companies are required to dispose
waste according to specific conditions
Ministerial Order2 to measure PFAS in wastewater in France: Companies have 3 months to submit list of PFAS likely to be or
to have been released Mandates 3 consecutive monthly analysis on all aqueous
discharge points likely to present significant PFAS presence (e.g., industrial effluents, etc.) Defines measure of concentration of 20 types of PFAS, fluoride levels (by Aqueous Organofluoride) and other substances
Recommendations3 for nationwide assessment of contamination and disposal of PFAS-contaminated water and soil Defines measure of concentration of 13 types of PFAS Measure and technique of fluoride levels for aqueous & solid
samples and quantification of unknown PFAS

Proven PFAS Treatment Methods
There are some proven treatment methods for PFAS today, although incineration is the most usually adopted
Treatment category Separation
Capture
Destruction
Technology High-Pressure Membranes
Granular Activated Carbon (GAC)
Anion Exchange Resin (AER)
Incineration/Thermal oxidation*
Type of waste Liquid
Liquid
Liquid
Slurries and solid
Description
High-pressure membranes, such as reverse osmosis and nanofiltration, effectively remove PFAS by using pressure to force water through semipermeable membranes, selectively filtering out PFAS and other contaminants
High temperature technology ( >700 C) GAC is a highly efficient adsorption technology that captures PFAS from water by attracting them to the surface of tiny carbon particles GAC has limitations but is widely used (~85% of capture installations). After use, GAC media can be reactivated and reused
High temperature technology ( >700 C) AER is a treatment technology that effectively removes PFAS from water by using resin beads that exchange negatively charged PFAS ions with chloride ions in the resin, thereby capturing and removing PFAS contaminants from the water
High temperature technology ( >700 C) Thermal oxidation or incineration is a high-temperature treatment process that breaks down PFAS contaminants into non-hazardous byproducts through combustion, rendering them harmless and suitable for safe disposal The further application of thermal technologies will depend on the ongoing evaluation of the fate of PFAS residual waste in solids and gas phases

Treatment category Separation
Capture
Technology Flotation
Novel Adsorbents/ Precipitants
Plasma, Catalytic Electrochemical Oxidation
and Sonolysis
Type of waste Liquid Liquid
Liquid
Description
Microbubble technology (ozone or air) works to concentrate PFAS in a froth. Flotation is best suited for very high initial PFAS concentrations
These technologies involve the use of innovative materials and methods to effectively remove PFAS contaminants. Some examples of novel adsorbents and precipitants for PFAS removal include clay-, cellulose- or starch-based options. Some may have an affinity for small chain PFAS. Further testing is required
Plasma destruction utilizes high-energy plasma to break down contaminants, electrochemical oxidation (EO) relies on electrical currents for degradation, and sonolysis employs ultrasonic waves to promote the breakdown of pollutants These developing technologies hold potential for on-site destruction
Destruction
Pyrolysis and Gazification
Supercritical Water Oxidation (SCWO) Hydrothermal alkaline
treatment (Halt)
Slurries and solid Slurries and solid
Liquid
Technologies that restrict the inflow of oxygen during high-temperature treatment are primarily suited for managing wastewater biosolids. These technologies are typically combined with thermal oxidation to control off-gas emissions More research is needed to assess the effectiveness of PFAS destruction in the gaseous phase
Technology that subjects PFAS-containing materials to supercritical water conditions (high temperature and pressure), which results in the complete oxidation of PFAS compounds into non-hazardous byproducts
Technology that subjects contaminated materials to high temperatures and pressures in the presence of alkaline substances, effectively breaking down and neutralizing pollutants

Key Challenges for PFAS Management Plans
However, the further adoption of PFAS management plans in refineries faces the following challenges
Current state
Unclear requirements due to legislative variety
Dependence on external capabilities
Other Drawbacks
Companies' plans are compliant to national and regional regulation
Half the companies in our scope are working towards developing their wastewater management plans
No dedicated PFAS management plan in place for polymers today
Companies cannot invest in a technology and establish a process without confirmation that it will correspond to requirements of license to operate
Variety in legislation - including existing local rules and wider regulatory requirements - with potential varying requirements, create a heavier burden for companies to comply
Refineries rely on specialized laboratories to conduct detailed PFAS analysis but there are only a few able to measure concentration of PFAS in water/soil
Companies also rely on waste contractors to collect and select the most applicable technique to manage PFAS waste
Limited options for disposal in end-of-life management including few incineration laboratories available
High GHG emissions from high temperature elimination techniques
Limited footprint in refineries for installation of additional processes
Expenses would increase as PFAS dismantling in equipment at end of life is complex and costly
Difficulty to fulfill the diversity of customer requests regarding PFAS presence in products

Drawbacks of PFAS Alternatives
Aside the material performance, alternative materials have other drawbacks that would make substitution challenging
Safety of the future installations
As they are not widespread use material, need to demonstrate performance in the long term of existing alternatives. Some known reduced performances: sealing, emission
International well established design standards for PFAS-based equipment in the industry will have to be updated, such as:
- ISO
- API
- ASTM
Alternatives development
Long process of developing substitutes potentially lasting many years, requiring:
- R&D
- Testing
- Approval from certifying bodies and clients
Long guarantee of new products required by clients (typically around 10 years)
Properties of alternative materials
To satisfy the desired properties for equipment the alternative materials to PFAS will also be persistent materials, which will could bring similar challenges to PFAS long life
Production asset and supply chain adaptation
Production asset debottlenecking:
- New sites to be built from scratch for some materials and equipment (e.g., high nickel alloy or ceramic piping used in niche applications)
- Important brownfield modifications on existing installations (e.g., gaskets)
Challenges in procuring potential alternative material (e.g., tantalum)
PFAS presence in alternative materials/equipment
PFAS potentially used to improve performance of alternatives:
- Some alternatives coated with thin layer of PFAS
- PFAS surfactants used in the production of non-PFAS polymers identified as theoretical substitutes to PFAS polymers

07 Conclusion
> Concawe
Ce-..Cincawe
Key Conclusions
The results of the industry survey, interviews, advanced analytics and patent analysis lead to the following conclusions for the use of PFAS in Refineries and Fuel Distribution
As refineries do not manufacture PFAS, their use is mostly in solid form contained in industrial equipment, with low risk of exposure to the environment during operations also due to HSE measures in place
There is a growing effort in the industry to develop environmental management plans for PFAS, especially related to managing emissions of PFAS in wastewater
Despite challenges in collecting information on the use of PFAS, we have conducted an inventory of PFAS in Refining and Fuel Distribution Equipment
There is a lack of alternatives to PFAS for most industrial equipment today. For the uses identified, potential substitutes lack combined properties needed for critical safety requirements (e.g., hydrocarbon leakage avoidance)
PFAS (mostly fluoropolymers) have been detected in a large share of refineries' equipment, especially in everpresent components such as joints, valves, pumps, etc.
A PFAS ban in refinery and Fuel Distribution equipment would have severe impacts across the energy value chain, putting at risk fuel supply in Europe

Potential Operational Impact for Refineries
With few alternatives available, it is difficult to precisely quantify full operational impact of transforming refineries, however some clear elements are foreseen as problematic
Site closure
Maintenance
Supply interruption
Safety & liability
Uptime reduction of plant due to repeated closures, including shut down for substitution of core equipment and more frequent maintenance actions
Lack of availability in the supply industry not structured for such a required volume over a short period of time
Required timing to validate the feasibility at industrial scale would take several years
Existing plants maintenance costs increased x 2 to 3
The downtimes would be almost tripled due to the reduction of reliability, availability and safety
Necessity to revise maintenance programs, invest in staff training, or even redesign infrastructure
Lack of availability of maintenance resources for such a large change
Concawe Source: Accenture analysis of questionnaire
Supply interruption for fuel products up to end consumer (vehicles, cars, trucks, airplane, rail, ships, vessels, military etc.) when repair in legacy assets is not feasible (no spare-part manufacturer, spare part not approved by the authorities, etc.)
Risk for product safety and liability by missing standards
Increased risk of accident frequency, making refineries less safe for workers and for the public in the surrounding neighborhood
74
Potential Economic Impact for Refineries
Economically, what is foreseen is increased expenses and revenue loss due to higher costs in products as well as increased maintenance cycles and equipment replacement
CAPEX
OPEX
Revenues
End of business
Increased capital investments required for future acquisitions, equipment replacements, and potential infrastructural redesigns to accommodate PFAS-free alternatives resulting in high increase in CAPEX
For new plants, higher CAPEX and increased running cost could deter new investments in Europe
Increased maintenance cost due to replacement of PFAS equipment and to differences in lifetime or efficiency parameters of alternatives
Reducing the turnaround time would result in additional costs, (up to 100 M for one refinery)
Ripple effect on costs related to equipment lifespans, energy consumption, and even waste management
Increase in disposal costs
Concawe Source: Accenture analysis of questionnaire
Increases in expenditures and costs automatically result in drop of margin and revenue
End of business due to unbearable costs for some companies, including sales loss and all extra costs for exchange, disposal and production
75
Potential Social & Environmental Impact for Refineries
Restricting the use of PFAS would affect job stability and safety of operations while bringing drawbacks in volume of emissions and waste generated
Waste
Jobs
Safety
Environment
Increase in waste volumes and more frequent turnarounds with specialized companies due to shorter operating times
Increased costs for containment and disposal
Redesign emission treatments of plants, including specialized treatment methods to avoid environmental contamination
Updates in waste management contracts for plants and warehouses
Jobs at risk if companies get out of business due to permanent plants shutdown
Due to higher expenses, job stability at risk as companies might have to balance new extra costs and revenue loss
However, potential creation of new jobs related to maintenance, replacement, and contracts with specialized contractors
Concawe Source: Accenture analysis of questionnaire
Potential increase of emissions due to a higher chance of leaks resulting from alternatives not being as effective in preventing loss of primary containment
Similarly, increased risk for human health by leakage of fuels to soil and ground water
Increase in maintenance activities means increased exposure time for maintenance workers and a higher injury probability
Climate risk linked to increasing GHG-emissions
Failure to block urban-air pollution reduction
Risk for renewable fuels' volume reduction according to Renewable Energy Directive RED
Risk of wrong disposal of PFAScontaining equipment due to lack of availability of infrastructure to recover PFAS contained in products
76
Potential Impact on other EU Laws for Refineries
A comprehensive ban on PFAS would limit the use of technologies essential to reach goals set by existing and upcoming EU environmental legislation
FOR OIL COMPANIES
Renewables
Emissions
FOR OTHER COMPANIES
Environment
Risk of not meeting RED-quota in the energy transition for bio-based and other sustainable fuels
Risk of delaying/stopping the development of renewable liquid fuels that use the same equipment in companies' sites as for fossil fuels
Penalties for the end consumer and reduced budget for buying clean ZEV zero emission vehicle according CO2-fleet regulations
Risk for banning fuel cell technology (membrane) and electromobility (wires at retail charging)
Risk for electricity transport from off-shore wind energy
Risk for solar technology electrical insulation
