3 PROTEGO - at a glance More than 50 years ago, PROTEGO started developing special devices for protecting systems against explosions as well as pressure and vacuum relief valves that meet the highest standards for performance, pressure conservation, and tight seals. This yielded the original Braunschweiger FLAMEFILTER (Fig. 1) as well as a series of additional innovations that led to numerous patents and imitators. In close cooperation with scientifi c institutions, continued technical challenges were overcome to meet the increasing requirements for safety and environmental protection. Today, these products are used throughout the world under the brand names PROTEGO and FLAMEFILTER mainly for the following applications: In tank farms for refi neries and chemical plants In processing plants for chemical and pharmaceutical industries In vapour combustion plants In ship building, offshore platforms, in loading facilities In vapour recovery systems As component for machineries and devices In biogas and landfi ll applications In fl are systems Our comprehensive product range reliably protects systems for generating, storing, and transporting gases and liquids of every hazard category against dangers such as endurance burning, defl a- gration and detonation. Our complete line of valves enables tank farms to be safely and economically ventilated. In addition, PROTEGO offers unique combinations of fl ame arresters and valves. All of our devices are tested by independent national and international third parties in the world s largest test facility and have got at least one of the many certifi cations. The actual performance of the devices is determined in a modern fl ow measuring test rig to obtain reliable data for their practical use. PROTEGO, FLAMEFILTER, and FLAMMENFILTER are international trademarks owned by Braunschweiger Flammenfi lter GmbH. FM Approvals Specifi cation Tested for safety and environment 3

4 Detonation Flame Arrester Function and description The function of fl ame arresters in the various combustion processes and applications is discussed in Technical Fundamentals ( Vol. 1). In this chapter, PROTEGO s product line of detonation arresters for stable and unstable detonations is presented. PROTEGO detonation arresters are highly developed safety devices that are used in pipe systems in which detonations can occur. They reliably suppress the effect of a detonation, extinguish the fl ame, and protect non-explosionproof components and vessels. The main component is the original PROTEGO fl amefi lter (1), which takes the energy from the detonation and extinguishes the fl ame in narrow gaps. The fl amefi lter consists of several fi lter discs (2), fi rmly held in the fi lter cage (3). The gap size and number of fi lter discs are determined by the operating parameters of the processed mixtures fl owing in the line (explosion group, pressure, temperature). Special features and advantages The most important distinctive features are the following selection criteria: Stable or unstable detonations, dry detonation arresters for installation in gas- or vapor-conducting pipes, or liquid detonation arresters, i.e. fl ame arresters with a liquid barrier for pipes in which liquids are transported. For the parameters of pressure and temperature, special operating conditions that go beyond standard values may have to be taken into consideration. It is important to categorize the products or the components of the mixture into explosion groups depending on their MESG to select the suitable type of protection from the various designs for all the explosion groups. The suitable or required approvals must be selected from the many that exist. The designs differ according to their concentric, eccentric, and 90-degree design. The respective system specifi cation must be considered when choosing the required nominal diameters and types of connection. A heating jacket may be necessary, but not every device can be provided with a heating jacket. There are designs for critical media, special product properties (such as viscosity, density, crystallization, and polymerization), and for unidirectional and bidirectional protection. PROTEGO fl amefi lter For larger nominal diameters, energy is withdrawn from the detonation shock wave upon entering the patented shock absorber (4), the SWGTE (shock-wave guide tube effect), and other innovative technical solutions, before the detonation reaches the fl amefi lter. PROTEGO detonation arresters are also tested and safe with respect to in line defl agrations. Equipped with an additional temperature sensor, they are also protected from short-time stabilized burning on the fl ame fi lter. In close collaboration with scientifi c institutions, PROTEGO has developed safety devices that can be used in any area subject to an explosion hazard and protects against stable and unstable detonations, unidirectional or bidirectional. Corresponding statements of conformity (CE, FM, etc.) have been awarded based on type tests according to ATEX, PED, and other international standards. A wide spectrum of types, designs, nominal diameters and materials are available. In addition, we are able to develop tailored solutions at our worldwide unique testing facility. Preferred applications Protection of piping systems tanks and vessels in chemical, petrochemical, and pharmaceutical processing plants loading systems gas collection systems exhaust gas combustion systems fl are systems landfi lls and biogas systems waste-water treatment plants 4 All rights and alterations reserved acc.

5 Installation and servicing PROTEGO detonation arresters are also tested and protect against defl agrations so that they can be used at any distance from a potential ignition source. However, they are preferably installed as close as possible to the part of the system to be protected. Any installation direction can be chosen, but the location and direction of fl ow need to be taken into account when the temperature sensor is designed. No pipes with a nominal diameter greater than the nominal diameter of the devices can be connected to detonation arresters. Given the modular design of the fl amefi lter, all PROTEGO detonation arresters are extremely easy to service. For servicing reasons, the fl ame arrester must be located to be very accessible; a hoist must be provided if the fl ame arrester is heavy. Servicing is easy for trained personnel. PROTEGO detonation arresters are used in areas subject to explosion hazards. Select devices that match the intended use. The manufacturer s statement of conformity confi rms the tasks for which the fl ame arrester is suitable. The user documents proper use in accordance with the applicable safety regulations. Selection and sizing Selection Sizing The nominal diameter of the device is determined or checked in the p/v performance diagram. A safety margin must be provided when the processed fl uid is highly contaminated. Given: volume fl ow (m 3 /h) and maximum allowable pressure drop ( p in mbar) Requested: nominal diameter of the detonation arrester (DN) Procedure: intersection of the lines with the volume fl ow and maximum allowable pressure drop lies above or on the desired nominal diameter curve or Given: volume fl ow (m 3 /h) and nominal diameter of pipes (DN) Requested: pressure drop ( p in mbar) Procedure: intersection of the lines with the volume fl ow and nominal diameter curve, horizontal straight line leads to the desired pressure drop. Instructions on how to calculate the volumetric fl ow or infl uence of density are found in Technical Fundamentals ( Vol. 1). After all the steps are complete, the device can be completely specifi ed and requested or ordered. The possible types are pre-selected from the product line based on the most important process data: Stable detonations or unstable detonations Lines that conduct dry gas/vapors or liquids Standard or non-standard operating conditions (pressure and temperature) Explosion group of the transported mixture Finally, the following criteria are reviewed and selected: Approvals according to ATEX, FM, USCG, CSA, Ghost, GL, IMO, etc. volume fl ow V.

Function and Description c The DA-G series is a compact detonation arrester for installation in pipes with diameters up to 2, and is used, for example, in industrial applications such as gas analysis lines. Once a detonation enters the fl ame arrester, energy is absorbed from the shock wave, and the fl ame is extinguished in the narrow gaps of the original PROTEGO fl amefi lter (1). The fl amefi lter consists of several fi lter discs fi rmly held in a housing. The gap size and number of fl amefi lter discs are determined by the operating data and parameters of the mixture fl owing in the line (explosion group, pressure, temperature). To provide an optimum result between the housing size, number of fi lters and fi lter gap size, a device was developed that can be used for all explosion groups, IIA, IIB3 and IIC (NFPA Group The individual fl ame fi lter discs are easy to service and replace Useful for different applications Cost effi cient spare parts Possible installation of temperature sensors Design Types and Specifications There are three different designs Basic design of the DA-G in-line detonation fl ame arrester, size ½ to 2 In-line detonation fl ame arrester with integrated temperature sensor* as additional protection against short burning from one side, size 1½ to 2.

12 with cut-off valve, unidirectional PROTEGO DR/SV a Once a detonation enters the fl ame arrester, energy is absorbed from the detonation shock wave by the central plate disc (2) before the fl ame is extinguished in the narrow gaps of the original PROTEGO fl amefi lter (3). This device can be used for fl uids of explosion groups IIA (NFPA group D). DN DN b DR/SV in-line detonation fl ame arresters are unidirectional and equipped with a threaded connection. The thread can be adapted to international standards. The standard design is approved at an operating temperature of up to + 60 C / 140 F and an (absolute) operating pressure up to 1.1 bar / 15,9 psi. Type-approved according to ATEX Directive 94/9/EC and EN as well as other international standards. Special Features and Advantages Function and Description Connection to the protected side The DR/SV fl ame arrester series ideally combines the function of a detonation arrester with the advantages of a cut-off valve. In case of ignition, the fi re can be stabilized within the fl ame arrester when the fl ammable gas continues to fl ow. Inside the detonation arrester, there is a valve (1) that closes in case of fi re and stops the additional supply of fuel which extinguishes the fl ames. Temperature sensors in combination with an emergency switch off do not have to be installed when a type DR/SV fuse is used. This device is particularly useful for the intake-side protection of compressors and pumps. The fl ame arrester protects against defl agrations and stable detonations. It can be installed anywhere in the pipe independently from the distance of the potential ignition source. Protects against stabilized fl ame No expensive emergency-off switches are required Temperature monitoring is not necessary Minimum number of fi lters Easy to maintain The individual fl amefi lters can be quickly installed and removed The fl amefi lters can be individually replaced Cost effi cient spare parts Provides protection from defl agrations and stable detonations Ideal protective system for vacuum pumps Table 1: Dimensions To select the nominal size (DN), use the fl ow capacity charts on the following pages DN 15 / G ½" 20 / G ¾" a 115 / / 4.53 b 100 / / 3.94 Dimensions in mm / inches Table 2: Selection of the explosion group MESG Expl.

Special Features and Advantages Optimized performance from the patented shock wave guide tube effect (SWGTE) Minimum pressure loss and associated low operating and life-cycle costs The flamefilter discs can be individually replaced Low number of filters from the use of the patented shock tube (SWGTE) Connection to the protected side (only for type DA-SB-T-...) Function and Description The DA-SB in-line detonation fl ame arresters are the newest generation of fl ame arresters. On the basis of fl uid dynamic, explosion dynamics calculation and decades of experience from fi eld tests, a product line was developed that offers minimum pressure loss and maximum safety. The fl ame arrester uses the shock wave guide tube effect to optimally decouple the fl ame front and shock wave. The result is a detonation arrester without a classic shock absorber; in addition the use of fl amefi lter elements is minimized. The devices are symmetrical and offer bidirectional fl ame suppression. The arrester essentially consists of two housing halves with an integrated shock tube (1) and the PROTEGO fl ame arrester (2) in the center. The fl ame arrester is modular and consists of several fl amefi lter discs (3) fi rmly held in a fi lter cage. The number of fl amefi lters and their gap size depends on the arrester s conditions of use. By indicating the operating parameters such as the temperature, pressure and explosion group, and the composition of the fl uid, the optimum detonation arrester can be selected from a series of approved devices. DA-SB fl ame arresters are available for all explosion groups. The standard design is approved for an operating temperature up to + 60 C / 140 F and an absolute operating pressure up to 1.1 bar / psi.

26 for unstable and stable detonations and deflagrations in a straight through design with a shock tube, bidirectional PROTEGO DA-UB Ø a DN Connection to the protected side (only for type DA-UB-T-...) Function and Description Design with one or two temperature sensors The DA-UB series of in-line detonation fl ame arresters is the newest generation of fl ame arresters. On the basis of fl uid dynamic and explosion-dynamic calculations and decades of experience from fi eld tests, a line was developed that offers minimum pressure loss and maximum safety. The device uses the shock wave guide tube effect to optimally decouple the fl ame front and shock wave. The result is a detonation arrester without a classic shock absorber, and the use of fl ame-extinguishing elements is minimized. The devices are symmetrical and offer bidirectional fl ame arresting for defl agrations, stable and unstable detonations. The arrester essentially consists of two housing halves with an integrated shock tube (1) and the PROTEGO fl ame arrester (2) in the center. The fl ame arrester is modular and consists of several fl amefi lter discs (3) fi rmly held in a fi lter cage. The number of fl amefi lters and their gap site depends on the arrester s conditions of use. By indicating the operating parameters such as the temperature, pressure and explosion group and the composition of the fl uid, the optimum detonation arrester can be selected from a series of approved devices. DA-UB fl ame arresters are available for explosion groups IIA to IIB3 (NFPA group D and C 0.65 mm MESG). b 1 Shock tube 2 Flame arrester 3 Flamefi lter discs DN NG c dismantling dimension for servicing (temperature sensor) The standard design is approved at an operating temperature of up to + 60 C / 140 F and an (absolute) operating pressure up to 1.1 bar / psi.

44 for unstable and stable detonations and deflagrations in a straight through design with shock absorber, bidirectional PROTEGO DA-CSA Design with one or two c dismantling dimension for servicing (temperature sensor) DN temperature sensors DN NG Ø a Connection to the protected side (only for type DA-CSA-T-...) b Function and Description The DA-CSA series of detonation arresters was developed especially for the North American market and optimized to meet the demands of the US Coast Guard and Canadian Standards Association (CSA). The devices are symmetrical and offer bidirectional fl ame arresting for defl agrations, stable and unstable detonations. The speed of incoming detonations is greatly reduced by the effective shock absorber (1). This improves the fl ame extinction in the narrow gaps of the original PROTEGO fl amefi lter (2). The arrester essentially consists of two housing halves (3) with an integrated shock absorber (1) and the PROTEGO fl ame arrester (4) in the center. The fl ame arrester is modular and consists of several fl amefi lter discs (2) fi rmly held in a fi lter cage. The number of fl amefi lters and their gap size depends on the arrester s conditions of use. By indicating the operating parameters such as the temperature, pressure and explosion group and the composition of the fl uid, the optimum detonation arrester can be selected. The DA-CG series of fl ame arresters is available for explosion groups IIA to IIB3 (NFPA group D and C 0.65 mm MESG). The standard design can work at an operating temperature of + 60 C / 140 F and an absolute operating pressure up to 1.2 bar / psi. The fl ame arresters have been approved together with FM Approvals according American Standard 33 CFR part 154 and the conditions of the CSA. Special Features and Advantages Offers protection against defl agrations, stable and unstable detonations Few fl amefi lters are needed due to the effective shock absorber The modular design enables individual fl amefi lter discs to be exchanged Cost effi cient spare parts Service-friendly design Low life-cycle costs Also available for large nominal sizes and high operating pressures Bidirectional operation as well as any direction of fl ow and installation position Design Types and Specifications There are three different designs Basic in-line detonation fl ame arrester In-line detonation fl ame arrester with integrated temperature sensor* as additional protection against short time burning of one side Detonation arrester with two integrated temperature sensors* for additional protection against short time burning from both sides DA-CSA- DA-CSA- T DA-CSA- T - B Additional special fi ttings upon request *Resistance thermometer for device group II, category (1) 2 (GII cat.
