Fixed Gas & Flame DetectionBecause every life has a purpose...Product Range OverviewPermanent Gas Detection SystemsMonitoring of gases and vapours in plants and large areas is necessary in all branches of industry. Directives and regulations covering the protection of plant and personnel require suitable gas detection equipment.When personnel monitoring is not available orsuitable, permanently installed detectionsystems (detectors and controllers) are usedfor continuous monitoring. These permanentdetectors are strategically positioned tooptimise detection coverage and can initiatea variety of safety related actions in the eventof a gas alarm.Examples of appropriate actions are theactivation of audible/visual alarms orventilation/ extraction systems and shutt i ngdown of plant equipment.According to the ATEX manufacturer directive94/9/EC and the user directive 1999/92/ECany gas detection system if used as a safetyrelated device to reduce the risk of explosionhas to be performance approved. The EC typetest certificate for the product must thenshow compliance to EN 60079-29-1 orEN50104. For more d etails on standards andregulations please see page 6.MSA provides a complete range of productswith full ATEX approval that can be used assafety related devices. For complete ATEXcompliance choose MSA.3MSA /detectionAbout MSA and General MonitorsOver 100 years of experience and capability in comprehensive safety solutions have made MSA a modern and forward-looking company for the protection of people, facilities, and the environment. MSA is one of the few suppliers of fixed gas and flame detection (FGFD) measurement technology that develops and manufactures a complete range of products and integrates them into safety solutions.With the acquisition of General Monitors inSeptember 2010, the MSA FGFD productportfolio expanded even further. As twounmatched experts in gas and flamedetection joined forces, we are proving thatthe right mix of durable products andinnovative technology can increase safetywhile driving operational efficiency.Together MSA and General Monitors have thewidest range of sensing technologies for gasand flame detection. We can create solutionsthat will not only provide worker safety andprotect facilities, but will also decrease overallcost of ownership. While our customers stillhave access to the great products and servicethat they have come to rely on in the past,they now have access to so much more:superior service, improved support, a widerrange of technology, and unique solutionsenhanced by the combined strength of MSAand General Monitors.Solid state sensors are based on the electronic conductivity effects when gases are adsorbed onto a semiconductor surface. In fact, this is a thin metal-oxide film deposited on a silicon slice. The process of production is similar to the one used for fabricating semiconductors; hence the name metal oxide semiconductor (MOS) for which they are commonly known. Adsorption of the gas on the oxide surface, followed by catalytic oxidation, results in a change of electrical resistance of the oxide material. The surface of the sensor is heated to a constant temperature to speed up the rate of reaction and to reduce the effects of ambient temperature changes. Resistance changes are converted into an electrical signal proportional to the concentration of the gas.Many gases absorb infrared light at certain wavelengths. The absorption spectrum is distinctive for each gas in question. Infrared Open Path and the Point Technology from MSA use electronically-modulated IR radiation sources at two different wavelengths. One wavelength is typical for the gas to be measured, while there is no infrared absorption by atmospheric gases for the other wavelength.The signals from both detectors are electronically amplified and fed into a microprocessor that conditions the signals and produces an output signal proportional to the gas concentration.Electrochemical sensors are typically used to detect toxic gases in the ppm range.Electrodes separated by electro l ytes are enclosed in a small plastic housing and are connected to an external electronic circuit. Gas diffuses into the sensor through a permeable membrane and a small current is generated by an electrochemical reaction.Since the rate of gas entry into the sensor is controlled by diffusion of the gas through the permeable membrane, the current is proportional to the gas concentration.The measurement principle behind this technology is based on catalytic combustion of the measured gas or vapours in air up to the Lower Explosive Limit (LEL) of the gas. The sensor consists of a pair of matched elements (PELEMENTS), a detector and compensator.The detector comprises a coil of platinum wire inside a small bead of catalytic material.The compensator is similar but does not contain a catalyst and therefore does not respond to gas. Combustible gases are oxidised only on the detector element, where the heat generated increases its resistance, producing a signal proportional to the concentration of combus t ible gas. The compensator helps to compensate for changes in ambient temperature, pressure and humidity which affect both elements equally.ElectrochemicalMOS – Metal Oxide Semiconductor Catalytic CombustionInfrared Absorption5MSA safety .com/detectionThe ultrasonic acoustic gas leak detection technology detects leaks from pressurized gas systems by sensing the airborne ultrasound produced by the escaping gas. This means that the ultrasonic gas leak detectors detect gas leaks at the speed of sound in a detection radius up to 20 meters.Unlike conventional gas detection methods (point or open path gas detection) the ultrasonic gas leak detectors do not have to wait for the gas to accumulate into a potentially dangerous gas cloud and come into physical contact with the detectors. They instantaneously raise an alarm if a leak is detected.The ultrasonic acoustic gas leak detector picks up the leak without being affected by conditions such as changing wind directions, gas dilution, and the direction of the gas leak –conditions relevant for most outdoor gas installations.Most flame detectors identify flames by so-called optical methods like ultraviolet (UV)and infrared (IR) spectroscopy. Flames are generally fueled by hydrocarbons, which, when supplied with oxygen and an ignition source, produce heat, carbon dioxide and other products of combustion. The reaction is characterized by the emission of visible, UV and IR radiation. Flame detectors are designed to detect the absorption of light at specific wavelengths, allowing them to discriminate between real flames and false alarms.MSA uses flame detectors based on UV/IR or multi-spectrum IR technology. Both technologies are based on line-of-sight detection of the radiation emitted in the UV, visible and IR spectral bands by flames.Photo-acoustic sensor technology was developed by MSA for the detection of toxic or combustible gases at very low concentrations. A gas sample is introduced into the measurement chamber and the sample is exposed to a specific wavelength of pulsed infrared light. If the sample contains the gas in question, it will absorb an amount of infrared light proportional to the concentration of gas present.The gas molecules heat and cool as they absorb the pulsed infrared energy. The pressure changes result i ng from the heating and cooling of the molecules are measured by a sensitive microphone located inside the photo-acoustic infrared monitor.Flame DetectionUltrasonicPhoto-acousticsCE MARKINGPlacing CE mark declares that product conforms to all applicable directives adopted by the EEA (European Economic Area). Unlike ATEX approval, the manufacturers are responsible for ensuring their product’s conformance to these directives which were developed using IEC and Cenelec standards.ATEXATmosphere EXplosible is French for potentially explosive atmospheres. According to ATEX manufacturer directive 94/9/EC (ATEX 95) and user directive 1999/92/EC (ATEX 137) the electrical safety of all electronic gas detectors and personal monitors used in potentially explosive atmospheres must be tested and marked “ATEX” (EN 60079-0 et seq.).If the gas detection system (detectors and controller) or personal monitor for flammable gases and vapours is used as a safety device “with a measuring function for explosion protection” it must be performance approved by a notified body in addition to the “ATEX” marking.Performance ApprovalAccording to the ATEX manufacturer directive 94/9/EC and the ATEX user directive 1999/92/EC any gas detection system (detectors and controller) and any personal monitor for flammable gases, if used as safety device to reduce the risk of explosion, has to be performance approved. Performance approval is also required if the oxygen content of the air during inertisation or the concentration of toxic gas needs to be measured.The EC type test certificate must then show compliance at least to EN 60079-29-1, EN 50104, EN 45544 and EN 50271.Flame detectors are not subject to this performance approval. However, approval in accordance with EN 54-10 can be carried out for these.SIL – Safety Integrity LevelAccording to directives 94/9/EC and 1999/92/EC (ATEX) only certification of electrical safety and possibly performance approval are required for gas detection devices. The production of an explosion protection plan for individual existing operating conditions may require measures that go beyond the ATEX requirements to be taken for stationary gas detection devices. The purpose of this additional safety evaluation is to minimise the risk in all applications where erroneous behaviour will result in danger to the safety of persons, the environment and property. Four values are defined as Safety Integrity Levels (SIL). The higher the integrity level, the greater the reliability of a functional circuit. Gas detection devices can only achieve levels SIL1 to SIL3.Products used in safety systems must show a considerably degree of hardware and software reliability so that non-detectable errors can only occur with extremely low probability. The benchmark for this safety-related evaluation of systems is the IEC/EN 61508 standard, which is also used for risk assessment in international process control engineering. This certification, which concerns system safety, defines the requirements of the availability of the safety function and the failure probability of the system that is under examination, as is required in process control engineering.As an application-independent basic standard EN 61508 only describes the general requirements for components and complete systems with safety functions. Therefore it’s inadequate for gas detection devices which also have to fulfil other safety criteria. For this reason EN 50271 and EN 50402 for gas detection devicesalso apply in this case.PerformanceApprovalExplosion protection is extremely important when dealing with flammable gases and vapours. The devices and assemblies that are to be used in this area therefore constitute a risk minimisation measure. As electrical equipment, industrial gas detection devices must fulfil at least the applicable requirements for operating in potentially explosive areas. Within the European Union, this is regulated by using the relevant harmonised European Directives (94/9/EC and 1999/92/EC).Correspondence with other globally accepted standards must also be ensured during the construction of the electricalequipment.MSA safety .com/detectionMeasuring Range 0–1000 ppm:ACETALDEHYDE, ACRYLONITRILE, AMMONIA, ACROLEIN, 1,3 BUTADIENE, CHLOROFORM, CYCLOPENTANE, 1,2 DICHLOROETHANE, DIETHYL ETHER, DIFLUOROMETHANE, DIMETHYLAMINE, ETHYL ACETATE, ETHYLENE, HEXAFLUOROPROPYLENE, HEXAFLUORO 1,3, BUTADIENE,ISOHEXANE, METHANOL, METHYL FLUORIDE, METHYL IODIDE, MIBK, METHYL METHACRYLATE, METHYLENE CHLORIDE, METHYLENE FLUORIDE, METHYL N-PROPYL KETONE, MONOMETHYLAMINE, NITROGEN TRIFLUORIDE, NITROUS OXIDE, OCTAFLUORO- BUTANE,OCTAFLUOROPROPENE, PENTANE, PERCHLOROETHYLENE, PMVE, PROPANAL, N-PROPANOL, PROPYLENE OXIDE, TETRACHLOR- METHANE,TETRAHYDROFURAN, TETRAFLUOROETHYLENE, 1,1,1 TRICHLOROETHANE, 1,1,2 TRICHLORO -ETHANE, TRICHLOROETHYLENE, TRIETHYLAMINE,VINYL ACETATE, VINYL CHLORIDE, 0-XYLENE, M-XYLENE, P-XYLENE, XYLENES CHILLGARD RT & CHILLGARD M-100 Application TableThe above-mentioned configurations for CHEMGARD, CHILLGARD RT and CHILLGARD M-100 are approved according to CE mark standards.8CHEMGARD Application TableMSA /detection 9IECExThe IECEx Scheme is an international certification scheme covering equipment that meet the requirements of international standards; most notably IEC 60079.CSA INTERNATIONALCSA International is an organization that provides performance testing in agreement with national and international standards.

2．仪表监控系统技术方案本方案是对该工程的仪表以及自动化控制系统的构成、功能、设备选型和技术特性等作进一步的阐述和说明。
2.1、控制系统描述2.1.1 控制系统概述整个仪表自动控制系统由现场仪表、传感器、变送器加控制中心的PLC可编程控制器和上位工控机、网卡以及相关的编程软件、应用软件组成。
控制系统按功能划分为三个区域和一个控制中心，三个区域是LNG储罐区、气化区和调压计量区。

LNG工厂防爆视频监控方案
1.1视频监控系统总体设计思路✧由于液化天然气工厂的视频监控系统，有不同一般的安防建设要求，不能像一般的公共建筑、小区等风险等级来做设计：✧视频监控的部位要涵盖LNG化工厂出入口、液化气生产区域，存储区域，内部主要道路、重点工作区、等区域。
✧在监控前端采取高分辨率彩色摄像机，考虑到夜晚库区没有辅助光源，摄像机采用彩色黑白模式自动转换的摄像机，并配合无红爆远距离红外灯使用，可以达到夜晚无光线环境正常进行监视厂区。
✧录像方式采用工控数字硬盘录像方式，所有图像的资料保存时间不少于30天。
并具有资料的永久备份功能。
✧主控中心显示部分采取一台22"纯平彩色显示器显示各部位的图像。
并具有分控键盘切换显示任意图像的功能。
供电系统采取集中供电方式。
第一章LNG工厂防爆监控系统设计方案2.1视频监控子系统2.1.1视频监控摄像机的布置考虑到投资额度，在有限的投资下达到最佳的监控效果，要对摄像机合理配置及合理调整安装位置。
根据库区建筑的结构形式，我们把摄像机进行如下布置：LNG化工厂防爆视频监控系统配置单2.1.2彩色与黑白系统选择视频监控系统的工程内容包括：﹒前端摄像机﹒镜头﹒防护系统﹒视频、控制、电源线路传输﹒中心控制系统﹒录像系统﹒图像显示系统其中只有前端摄像机、显示系统是区分黑白和彩色，传统的录像机和画面分割器也区分黑白和彩色，但从硬盘录像系统逐渐成熟之后，传统的录像和画面分割慢慢淡出市场。
其它所有环节都可以兼容彩色或黑白系统。
而前端摄像机和图像显示系统在整个工程中的造价一般只占1/3左右，按照彩色配置组建的视频监控系统，在机房的整体效果上将会好很多，不会有一部分是黑白、一部分是彩色的不协调情况。
因此我们建议统一选择彩色摄像机，这样的监控图像更直观明了，监控中心彩色画面也更富有现代气息。
2.1.3视频监控主控制室管理方式LNG化工厂对视频监控系统的实际需要，监控室采用性能稳定、功能强大的16路硬盘录像机，配套22寸工业监视器实现全网监控。
