FEATURES AND APPLICATIONS The Model 700 Process Gas Chromatograph is an advanced combination of technology and rugged instrumentation that helps make the most of existing manpower. Today’s trend toward downsizing means instrument technicians have more to do in less time. Instrumentation has to be more reliable and easier to use than ever before. Emerson’s Rosemount Analytical gas chromatographs are your best choice; we’ve built our reputation on equipment reliability and long-term performance with ease of use. The Model 700 is designed for a variety of refining, petrochemical, food and beverage, pharmaceutical, power and environmental applications where selected components in gaseous or liquid streams must be precisely monitored on a continuous basis. Refineries & Petrochem Catalytic reformer Isomerization unit Aromatics unit Ethylene plants Polymer plants Acrylonitrile plants Gas Processing NGL and LNG plants Cryogenic gas plants Power Generation Power generation plants Gas turbine control Environmental Monitoring Ambient air monitoring HR-VOCs in flares and cooling towers THE ROSEMOUNT ANALYTICAL GAS CHROMATOGRAPH DIFFERENCE Broad application scope with single- or dual- detector capability Extreme ambient temperature operation minimizes installation and utility requirements High-sensitivity thermal conductivity detectors can often replace the need for more complex detectors Easy-to-use MON2000 PC software for advanced diagnostics and simplified troubleshooting; simply the best in the industry Rosemount Analytical diaphragm valves offer a lifetime warranty GAS CHROMATOGRAPH VALVES The chromatograph valves used in Rosemount Analytical gas chromatographs are unique to the on-line gas chromatograph market. Using a design originally developed by NASA, the valve offers greatly extended operating life. Emerson Process Management is currently the only on-line gas chromatograph supplier to offer a lifetime warranty on their Rosemount Analytical chromatograph valves! Choice 6-port and 10-port, diaphragm valve Simple mechanical design Sample does not come in contact with internal moving parts More than 5 million operations per valve Lifetime warranty on diaphragm valves Rotary and Liquid Injection Valves also available as applications need The reason for the exceptional durability of the valve is its unique double-diaphragm actuation. The doublediaphragm design eliminates the need for springs, O-rings and lubrication. Flow paths in the valve are arranged so that internal moving parts never contact the sample flow. As a result, abrasive mechanical wear on machined valve surfaces is eliminated. The valves are rated for over 5 million operations before repair (approximately 3-5 years of usage). And then, repair is typically simply changing the diaphragms in the valve. Detectors The Model 700 Process Gas Chromatograph has the selection of detectors to handle the wide range of analytical demands found in typical process applications. Whether the components of interest are in the percent range or down to the parts-per-million range, precise and reliable measurement is possible. TCD detector is sensitive down to 3 ppm Micro-FID detector is sensitive down to the parts-per-billion level Dual TCD / TCD or TCD / FID configurations possible FPD module available for trace sulfur analysis The TCD thermistor is the detector of choice for most applications due to its universal response to all compounds. Emerson's Rosemount Analytical TCD is able to go well beyond the normal measuring ranges seen in other designs by being able to do many applications with low parts-per-million measurement requirements. This greatly simplifies the gas chromatograph design when a simple and rugged TCD can be used rather than FID. For measurement of most organic compounds in the low ppm or even ppb ranges, the Flame Ionization Detector (FID) is an option available for the Model 700. Its micro design is perfect for the transmitter-style enclosure of the Model 700 without sacrificing analytical power. Most important, the Rosemount Analytical valve offers excellent performance. The valve is available in both 6-port and 10-port versions to handle both simple and complex column valve arrangements. Minimal internal movement of the components in the valve – roughly 1/1000th of an inch – contributes to rapid actuation of the valve, which can be important for applications using micro-packed and capillary columns. HEAT SINK OVEN The Heat Sink Oven design of the Model 700 brings stable and precise measurement to the field without the need for expensive analyzer shelters. Airless oven analytical kiosk with oven temperatures up to 100°C Up to 3 six or ten port diaphragm valves for maximum analytical flexibility Micro-packed columns mounted in the center of the heated kiosk for stable performance over the analyzer’s entire ambient temperature rating The Heat Sink oven of the Model 700 is a triangular shaped solid stainless-steel kiosk that can accommodate up to three chromatograph valves and two detectors. It also contains the chromatograph columns. This unique design, with oven temperatures up to 212°F (100°C), is standard for the Rosemount Analytical Model 700 process gas chromatograph. COLUMNS Since 1980, Emerson Process Management has been refining and improving its process for creating micropacked columns. Rosemount Analytical micro-packed columns offer a superior combination of the features found in both capillary and conventional packed columns. The result is improved chromatography with extended column life (several years in most applications without measurable degradation or bleed). Rosemount Analytical micro-packed columns produce sharper peaks for improved component separation, short analysis time and very low carrier-gas consumption. THE DESIGN MAKES THE DIFFERENCE Built tough to stand up against any environment Tested tough to insure performance Field-mountable technology means solid performance at reduced cost Valves built so well, they’re guaranteed for life! Detector options that meet your requirements Micro-packed columns that are made to last Maintenance of the Model 700 oven is simplified with all components mounted on the surface of the kiosk making access easy. Furthermore, the kiosk is mounted on a rotating plate that can be pivoted out of the way when access to other components is needed. MON2000 PC WORKSTATION The Model 700 Process Gas Chromatograph is designed to operate unattended. If however, adjustments are needed; our exclusive MON2000 software allows complete control of you gas chromatographs – either locally or remotely. From within MON2000, a user can: Review and modify analytical settings Upload and display multiple chromatograms on the screen for comparison Upload and trend any of the measured results Export data for use in other 3rd party applications Overlay multiple chromatograms for troubleshooting and calibration Check original calibration against last calibration The MON2000 PC Workstation Software is Windows™ - based software to make analyzer configuration, maintenance and data collection easy. With intuitive drop-down menus and fill-in-the-blank tables, even new users can quickly navigate through the software. The MON2000 software can display both current and multiple archived chromatograms on the screen streamlining the time needed to performance routine analyzer maintenance. MON2000 also has a number of tools built in that help users manage their analyzers such as: Automatic recording of alarms in a log file Event logs that provide a continuous record of all operator changes with time and user name stored Maintenance log scratch pad for keeping track of maintenance or testing done Data collected from the gas chromatographs can be stored and displayed in a wide range of options such as trend lines on the screen and logs automatically documenting all changes made to the gas chromatograph. Data can also be exported in formats compatible with most third-party Windows™ applications. ANALYZER NETWORKING AND DATA COMMUNICATION Emerson’s Rosemount Analytical gas chromatographs can be configured in a number of networking and data communication schemes to meet most process communication requirements. Options include Ethernet networks as well as multi-drop RS-485 networks. It is even possible to set up automatic polling for data collection over phone lines if desired. Data communication options to the plant control system include simple analog and discrete signals as well as Modbus serial links. To preserve the integrity of the analysis data, all Model 700 Process Gas Chromatographs are capable of storing up to 35 days of analysis and calibration data in the event of loss of communication to the plant control system. All Rosemount Analytical process gas chromatographs are designed to operate unattended. Occasionally, adjustments to the analyzers’ analytical method or a review of possible alarms may be needed. Using our exclusive MON2000 software loaded on either a PC or laptop running Windows™, you’ll have complete control of your gas chromatographs – either locally or remotely. With Ethernet, analyzers transmit directly to the plant’s digital control system (including DeltaV®) quickly and securely using either industry standard Modbus or the new OPC protocol. NETWORKING FLEXIBILITY Whether you want to network gas chromatographs throughout the plant or simply link a single gas chromatograph to the DCS system, the Model 700 can be configured to handle most any scenario: Choice of Ethernet or RS-485 network Can use same network to connect Model 700, Model 500 and Model 1000 gas chromatographs Able to connect multiple PC workstations using MON2000 Connectivity to plant control systems using industry standard protocols such as Modbus and OPC SECURE MODBUS CONNECTIVITY For process gas chromatographs, Modbus continues to be the preferred choice to connect a gas chromatograph network to the plant control system. Modbus design avoids the use of central interface cards or computers that can act as a single-point of failure in the Modbus link. Instead, the plant DCS system can “talk” directly to each gas chromatograph to gather the data needed. Furthermore, the register and coil addresses can be easy customized to meet the specific data structure of the DCS. There is also a program built into the MON2000 workstation to test the Modbus link to the DCS if troubleshooting is needed. The main electronics for the Model 700 Process Gas Chromatograph is mounted in a separate lower enclosure for protection of the electronics as well as providing easy accessibility. ENVIRONMENTAL CHAMBER TESTING Emerson Process Management provides the most thorough gas chromatograph testing in the world. Each Model 700 must operate to specification in our walk-in environmental test chambers cycling between 0°F and 130°F for 24 hours minimum. This is all part of our commitment to provide process gas chromatographs that are capable of providing reliable measurements in the field. Legendary measurement stability in extreme climates is tested for every Model 700 gas chromatograph before it ships. CUSTOM ENGINEERED SAMPLE SYSTEMS Any gas chromatograph is only as good as the quality of the sample it measures. So every sample system for Rosemount Analytical gas chromatographs are custom engineered for the specific requirements of the application. Common features include: Heated and open panel designs All components rated for the area classification Automatic calibration / validation available as an option Variety of sample probes to extract a reliable and stable sample from the process LOWER INSTALLATION AND MAINTENANCE COST Rosemount Analytical gas chromatographs offer some of the lowest cost of ownership in the industry. Most process measurements can be made at or near the sample point greatly reducing the overall lifetime cost of the measurement. Expenses such as shelters, air conditioning, heating, long/heated sample lines can be minimized or completely eliminated in most applications. Furthermore, Rosemount Analytical gas chromatographs are designed to operate unattended for long periods of time without adjustment. When adjustments are required, all components are easily accessible and can be performed in the field in minutes with standard tools.
