IES-RP-CC-008-84,"Recommended Practice for Gas Phase Adsorber Cell." In addition, the adsorber must be designed, built, filled and packaged in accordance with the intent of this standard.Since HEGA filters are manufactured in several different sizes and of several different materials, this standard is not always followed to the letter. It is the intent of the standard and the resulting performance of these adsorbers that is important.
This type of adsorber is not intended to be used in odor control systems.However, if the user needs a very efficient odor control system and can justify the higher initial and operating costs, then this type of adsorber will do an excellent job. The following comparison between an odor control type adsorber vs. a HEGA may help: " Nuclear Power Plants" Cancer Research Laboratories" Toxicology Laboratories" Animal Disease Research Facilities" Chemical Agent Research Facilities" Bomb Shelters (CBR)" Radiopharmaceutical Plants" HVAC Systems" Laboratories Using Chemical Carcinogens" Chemical Agent Munitions Disposal Facilities" Hospital Isolation Suites" Pharmacological Facilities
- Chemical Process Facilities" Military Facilities
- Biological Research Facilities
- Department of Energy Facilities How Does a HEGAWork?A High Efficiency Gas Adsorber (HEGA) filters gaseous contaminants from an airstream by adsorbing the contaminants (See Page 19,"Types of Adsorption").
With a properly designed system that includes proper adsorber selection, adsorbent and resident time, any adsorbable contaminant can be filtered and contained. (See Page 6 for "Adsorber Design and Performance.'
Page 20, "Residence Time").HEGA Selection When designing a system requiring HEGAs, consider: 1. Type: "Cinersorb" (p. 13), Type IV (V-Bed) (p. 7), or Type II Tray? (p. 17)2. Type of carbon needed? (p. 6 & 7)3. Residence Time: (See pp. 6 & 20)4. Need for sample canisters? (See p. 19)An odor control type adsorber compared to a HEGA is like comparing an ASHRAE type particulate filter to a HEPA. The odor control type adsorber (like the ASHRAE type particulate filter) has a low efficiency, low pressure drop and low cost. On the other hand, the HEGA (like the HEPA) has a higher efficiency, higher pressure drop and higher cost. Both adsorbers have their place in industry, but because of these major differences they are not usually interchange-able.Where are HEGA's Used?HEGA's are most often used in "containment" air filtration systems. Containment air filtration systems are very high efficiency systems, used to filter and contain dangerous particulate and/or gaseous contaminants.
Containment systems are most often designed to treat exhaust air from contaminated spaces, but occasionally are used in supply and recirculated air systems. Examples of facilities using these systems are: 4 ATTACHMENT 8 HEA Fites Deig Conidraton Design Considerations The following should be considered when designing a filtration system: 1. Any system that filters dangerous contaminants should incorporate bag-in/bag-out housings to contain the contaminated filters and protect maintenance personnel during filter change-out.
- 2. Particulate filtration must be provided upstream of HEGA filters to prevent the adsorber from trapping particulates and thereby increasing the adsorber's pressure drop.3. Some applications require high efficiency or HEPA filters located down-stream of the adsorber to collect any fines (dust which might be contaminated) released from the adsorbent material and to act as a backup in case the first particulate filter should fail.4. Filter trains can be easily constructed with any combination of roughing filters, high efficiency filters, HEPA filters and adsorbers (See illustration below).5. An in-place test of both adsorbers and HEPA filters is recommended for nuclear containment systems and is becoming a more frequent requirement for many critical applications.
The purpose of this in-place testing is to"validate" the installed system. The in-place test, if required, should be discussed with a Flanders/CSC factory representative prior to the selection of equipment so the system will be correctly designed to facilitate the test.In-place test equipment and service personnel are available from Flanders/CSC to assist in the original installation and testing.6. The filtration system should be manufactured under a good quality assurance program such as one that addresses all of the basic requirements of ASME NQA-1, "Quality Assurance Program Requirements for Nuclear Facilities." V-Bed Adsorber Applications From left to right: prefilter, upstream in-place test section, HEPA filter, V-bed adsorber, in-place combination test section, V-bed adsorber, HEPA filter, downstream in-place test section.5 ATTACHMENT 8 HEA Fites :-Be Adsorber Carbon Adsorbers Carbon adsorbers use activated or impregnated
/activated carbon as a filtering medium to remove gaseous emissions from nuclear, biological and/or chemical process exhaust air. Due to the potentially hazardous nature of their end use, the customer should consult with Flanders/CSC technical representatives as early as possible during the design phase of a project to assure proper specifications for the adsorbers and the filtration system. Flanders/CSC personnel have many years experience with gas-phase and HEPA filtration systems and can provide assistance in adsorbent selection, residence time calculations, and system configuration.
All units are manufactured in accordance with Flanders/CSC's quality assurance program, which meets the requirements of ASME-NQA-1, "Quality Assurance Program Requirements for Nuclear Facilities." Flanders/CSC tests each adsorber to insure a minimum mechanical efficiency (the percentage of air that actually contacts the activated carbon in a system without penetrating voids or cracks) of 99.9% per IES-RP-CC-008-84, "Recommended Practice for Gas-Phase Adsorber Cells." This test of the adsorber's efficiency on test agents is used to determine if the adsorber is properly manufactured and filled, but not whether it is suitable for a given application.
Residence Time Under actual operating conditions, the removal efficiency (the percentage of containment actually removed by the activated carbon during operation) of an adsorber is determined by the type and amount of contaminant in the gas stream, the type and amount of adsorbent, and the residence time (the time that the gas stream is in contact with the carbon). In most applications, a residence time of 0.125 second is sufficient.
In other cases, residence time is a critical factor that must be calculated for the specific contaminant. (See p. 20.)Applications Type IV (V-Bed) adsorbers are designed for use in Flanders/CSC BF-Series and BG-Series bag-in/bag-out housings for KF-Series and KG-Series high efficiency side-service housings.Occasionally they are used in large "front and rear loading" built-up banks inside walk-in plenums, but the Type II Tray adsorber is usually best suited for that system design.Adsorber Design and Performance All units are made with beds of carbon mounted in a "V" configuration at various depths and residence times at rated airflow depending upon customer requirements.
Various grades of carbon are available to meet specific removal requirements:

Incineratable High Efficiency Gas Adsorber The Cinersorb is the solution to problems associated with the disposal of carbon adsorbers contaminated with toxic, carcinogenic, microbiological, radioactive or other dangerous contaminants.
Many facilities have a waste disposal problem regarding high-efficiency adsorbers that are loaded with dangerous contaminants.
In the past, high-efficiency adsorbers (i.e.. adsorbers that exhibit a mechanical efficiency of 99.9%)have been manufactured with metal frames.Since these metal frame adsorbers cannot always be safely refilled with fresh carbon, their disposal becomes a problem.The Flanders/CSC Cinersorb, which has a combustible frame constructed of high impact polystyrene plastic, solves this problem.Features* Polystyrene frame allows disposal by incineration (volume reduction exceeds 95%)* Mechanical efficiency of 99.9% when tested in accordance with IES-RP-CC-008-84,"Recommended Practice for Gas-Phase Adsorber Cells"" Available in many sizes (See pp. 15-16), allowing use in most standard filter housings" Easier to handle, weighs 40 to 50% less than metal frame adsorbers" Less expensive than metal frame adsorbers* Corrosion resistant* Can be filled with any adsorbent to capture almost any contaminant" Many applications, including safety cabinet, glove box and fume hood exhaust, laboratory supply air and odor control Incineration guidelines vary from contaminant to contaminant.
The customer should determine that incineration meets the requirements governed by type of contaminant in question and local regulations.

Radioactive Iodine Performance Test Flanders/CSC can provide radioiodine testing services on samples of carbon to determine if the samples meet customer specifications.
Tests can be expedited to prevent extended downtime of the customer's air filtration system. Tests are performed to latest versions of ASTM-D3803, ASME N509 and ASME AG-1; but, any standard radioiodine testing can be performed.
Customer can also specify custom test parameters, if required.*US Nuclear Regulatory Commission Regulatory Guide 1.52,"Design, Testing and Maintenance Criteria for Post Accident Engineered-Safety-Feature Atmosphere Cleanup System Air Filtration and Adsorption Units of Light-Water-Cooled Nuclear Power Plants." Types of Adsorption There are three types of adsorption that concern us: 1. Kinetic, 2. Isotopic Exchange, and 3. Complexing or Chemisorption.
Kinetic: Kinetic adsorption of a gas molecule or chemical vapor is the physical attraction of the molecule to the carbon granule by electrostatic forces. These forces, as they apply to small particles, are governed by van der Waals theories, and these attraction forces are termed van der Waals forces. Since these forces are physical in nature, the forces can be undone by physical effort. Thus, high temperature, high humidity, or other natural causes may cause an adsorbed contaminant to desorb.Generally, the higher the boiling point, the larger the molecule size, and the lower the melting temperature, the easier the molecule is to kinetically adsorb and the stronger it is held once it is adsorbed.Isotopic Exchange:
A second "adsorption" mechanism is isotopic exchange.
Radioactive materials usually have a family of isotopes.
If a stable isotope is adsorbed on the carbon initially, an unstable isotopic compound will, when it comes into contact with the stable form of the element, exchange the isotopes.
The 19 ATTACHMENT 8 HE A Fites Cabo Sapln Sytm stable form is now on the airborne molecule and the radioactive form is on the molecular structure of the impregnant.
An example of this is carbon impregnated with K13. The radioactive form of iodine in the organic form CH 3 1 1 3 1 will isotopically exchange with the iodine on the carbon. This exchange is nondirectional, meaning the adsorbed (exchanged) radioactive species of iodine may very well exchange again. The result will be a different airborne radioactive methyl iodide molecule.
This new radioactive molecule may again isotopically exchange with stable iodides on the carbon in the K13 impregnant, and so on, until the radioactive iodine is delayed long enough to decay into stable xenon.Complexing or Chemisorption:
A third capture mechanism is chemisorption.
This is the actual complexing, attaching chemically, of a radioactive iodine species to a stable impregnant that has the ability to share electrons.
Once the iodine is complexed, it does NOT desorb similarly to isotopic exchange.However, it may desorb similarly to the kinetic adsorption discussed.
But if it does, the entire impregnant desorbs from the carbon, not just the iodine. An example of this is to impregnate the carbon with triethylenediamine (TEDA) or some other tertiary amine.To take advantage of both impregnants and capture mechanisms, carbon can be co-impregnated.
This allows the carbon to be used as a kinetic adsorber, an isotopic exchange medium and a complexing agent.As long as the operating conditions are kept within normal bounds, the carbon will perform as required.
It will perform under high humidity conditions and under high temperature conditions better than a carbon with a single impregnant.
Efficiency vs. Penetration There is often confusion between "efficiency" and "penetration" of contaminants through a carbon bed.Efficiency is the ability for the carbon to remove a desired contaminant.
Methyl iodide efficiency, for example, is determined by challenging the carbon with an actual radioactive methyl iodide vapor. The amount of the contaminant upstream of the carbon is known, and the amount that is collected on backup beds is measured.
The efficiency of that carbon sample to remove methyl iodide is easily calculated by comparing the counts of the carbon sample to the counts on the backup beds. Test parameters such as temperature and relative humidity greatly affect the efficiency.
Penetration, on the other hand, is a term used to indicate the degree of leak tightness for installed carbon systems. The installed system is subjected to a test gas that is easily adsorbed, such as R-1 1 (trichlorofluoromethane).
The penetration, or by-pass of the R-11, is measured downstream of the filter and that amount is compared to the amount measured upstream of the filter. A penetration value in percent is easily calculated from the collected data. This is also termed mechanical efficiency.
Residence Time Residence time is the term given to the time that a gas stream contacts a carbon bed. For example, if a carbon bed were a foot thick and the air stream moved at one foot per minute, the residence time would be one minute. It would take one minute for the air to move through the bed.Typically, the carbon bed is 1-inch thick and the air velocity is 40-feet per minute. What would 20 ATTACHMENT 8 HE A Fites eebnamln System the residence time be in that situation?
(0.125 seconds) The residence time can be calculated easily from the following relationships:
RT=5 xD V Where: RT = Residence time (seconds)D = Depth of carbon bed (inches)V = Velocity of gas through bed (feet/min)
Most of the time, the velocity will not be given and must be calculated from the relationship:
V= Q A Where: V = Velocity of gas through bed (feet/min)
A = Unbaffled area of carbon bed (sq.ft)Q =Quantity of gas flowing through bed (CFM)Let's take an example from real life: Assume that Q=1,000 CFM and that a single 6 panel, 16-inch deep (in direction of air flow), 2-inch bed depth filter is to be used. To calculate the residence time, first determine the area of the carbon bed. The total area is 12.5 sq. ft. The 12.5 ft 2 is determined by actual measurements of the unbaffied bed area on one side of the carbon filter. Therefore:
RT= 5x2 80 RT: 10 80 RT = 0.125 second The concept of residence time is very important from the designer's point of view. That is why Flanders/CSC is taking a lot of time to explain it fully. Flanders/CSC cannot design a system unless we know either the actual residence time required, or all of the parameters that determine the optimum residence time, (flow rate, contami-nants, concentrations, temperature, humidity, required efficiency, etc.)The residence time is critical to the chemisorp-tion or complexing phenomena.
As the gas enters the bed, it must have time to interact with the impregnants on the carbon. Too little time will mean that the contaminants will not interact completely with the carbon or impregnants.
Too much time means that the system is not de-signed efficiently.
In summary, you need to be aware of the important of residence time because the first question we ask about an inquiry for any carbon system is, "What is the residence time requirement?" If you do not know, we will have to determine it before the best system can be designed by our engineering staff.Capacity The capacity of activated carbon is the percentage of its own weight that an activated carbon can adsorb of a given vapor under certain conditions.
Some of these conditions are vapor concentration, temperature, humidity, air velocity, and defined breakthrough.
Example: If 100 pounds of activated carbon adsorbs 15 pounds of benzene before it reaches 21 A V = 1000 CFM 12.5 ft V = 80 ft/min And: RT= 5xD V ATTACHMENT 8 HEA Fitr an Fite Tetig Cabo Sapln System a customer defined breakthrough point of 5 ppm, then the capacity of that activated carbon for benzene is 15%.Decontamination Factor The Decontamination Factor is the ratio of the concentration of a contaminant in the untreated air to the concentration of the contaminant in the treated air.If anyone asks what the Decontamination Factor (DF) of a filter is, the answer can be obtained by calculating the RECIPROCAL of the penetration expressed as a fraction, or DF = 1 Pen.Examples: 2. Carbon filters must: a Exhibit a minimum mechanical efficiency of 99.9% (i.e., HEGA).b Use high quality coconut shell activated carbon.c Be sized for approximately 0.125 second residence time.3. All filters should be installed in "Bag-in/Bag-out" housings to protect main-te nance personnel and the environment.
- 4. Filtration system designs should have provisions for pulling samples of air or carbon for laboratory analysis (to assist in determining when carbon adsorbers need changing).
- 5. The disposal of hazaradous waste (i.e., spent HEPA and HEGA filters) should also be considered.
Any HEPA or HEGA filter containing regulated chemicals should be disposed of in accordance with Federal, State and local restrictions.
- 6. The filtration system must be manufac-tured under a good quality control program such as one that addressed the requirements of ASME NQA-1, "Quality Assurance Program Requirements for Nuclear Facilities."

HEPA filters should be used to trap dangerous particulates and protect the carbon filters from collecting particulates and thereby increasing the adsorber's pressure drop.22 ATTACHMENT 8 HEGA F It s Geeal Ifratino Carbon an Adsortio Materal The following are some random thoughts and information that will help you form a general idea about carbon filter technology.
These comments are to be considered as general axioms, and the reader should be able to "fill in" some of the unknown factors when unusual situations arise.However, there is no substitute for expert advice and opinion, and the reader is urged to contact Flanders/CSC for answers to any technical problem, specific questions or additional information.
1 Elemental iodine is adsorbed by attraction of the iodine to the carbon.This is called Kinetic adsorption.
2 Methyl iodide, which comes from elemental iodine (12) combining with methane must be adsorbed by chemisorption, usually in the form of isotopic exchange when KI carbon is used or complexing when TEDA carbon is used.3 The recommended residence time for methyl iodide is 0.25 seconds residence time per 2-inch bed. Tests have shown that the carbon will perform as required at twice that velocity or half that r esidence time for a limited time period.4 As the humidity increases, the ability of the carbon to perform is adversely affected.
However, the carbon must perform at 95% relative humidity in order to meet ASME AG-1 requirements.
5 The heavier the molecular weight of a material, the easier it is to adsorb.6 The higher the boiling temperature of a material, the easier it is to adsorb.9 The adsorption coefficient of carbon is the amount of a given material that the carbon will adsorb, by weight.10 Some hard to adsorb materials can be displaced by easier to adsorb materi-als. For example, acetic anhydride may displace acetone. Acetone may displace acetaldehyde, and acetalde-hyde may displace acetylene.
11 The lower the concentration of a material, the harder to achieve a high removal percentage.
12 One gram of carbon will adsorb one milligram of iodine. The potential inventory of radioiodine in a nuclear power system is very small.13 Since carbon will adsorb anything adsorbable, it can be poisoned by harmless materials and be unable to adsorb the material that it was designed to control. That is why the carbon should always be protected from vapors that will harm it.14 Shelf life of carbon in properly packaged drums or in filters having a vapor barrier of some kind can be as long as five (5) years. Flanders/CSC recom-mends that carbon over three (3) years old be retested to assure that it meets the efficiency requirements of the original specifications.
15 Methyl iodide adsorbs-desorbs-adsorbs through the bed, exchanging iodine at each juncture.
That is to say, methyl iodide can be radioactive-stable-radio-active-stable until it decays into harm-less xenon.16 Elemental iodine, once adsorbed, usually stays adsorbed.7 8 The converse of 5 and 6 is true.One gram of 60% active carbon (as measured by carbon tetrachloride) has a surface area of about 1,000 square meters.23
