APPLICATION FOCUS AN ESSENTIAL TECHNOLOGY FOR CARBON CAPTURE Carbon capture and storage (CCS) technologies are key to decarbonization strategies and are used to collect carbon dioxide (CO2) emissions from power plants and petrochemical processes, reducing the amount of CO2 that enters the atmosphere. Pre-combustion capture removes CO2 before the combustion of the fuel and requires a carbonaceous fuel to be broken down into a hydrogen (H2) and carbon monoxide (CO) mixture, cleaned, then ‘shifted’ before CO2 can be removed. Oxyfuel combustion capture is based on denitrification of the...

APPLICATION FOCUS TRUSTED PHOTOMETRIC SOLUTIONS FOR EDC PRODUCTION Ethylene dichloride (EDC) is an important intermediate in the predominant manufacturing process for polyvinyl chloride (PVC). The production of EDC requires accurate and reliable gas analysis at several points, with a variety of technologies – including photometric sensing methods – delivering the vital measurements for process control and quality monitoring. Gas analyzer systems used in this application must contend with challenging process conditions, including condensation and corrosion. Large amounts of hydrogen...

TECHNOLOGY FOCUS GAS FILTER CORRELATION GAS FILTER CORRELATION: HIGHLY SENSITIVE, HIGHLY SELECTIVE PHOTOMETRIC ANALYSIS Gas Filter Correlation (GFC) sensing is an enhanced version of the photometric analysis used in Servomex’s Infrared technologies. It performs effectively in applications where extremely accurate, low-level measurements are needed, or where background gases may interfere with the measurement. Gases absorb unique light wavelengths – GFC sensing takes advantage of that property to measure the concentration of a chosen gas in a mixture. It works in this way: two gasfilled...

APPLICATION FEATURE ENSURING AN EFFICIENT DRI PROCESS AN IMPORTANT ELEMENT OF MANY STEELMAKING PROCESSES, DIRECT IRON REDUCTION (DRI) INVOLVES THE REMOVAL OF OXYGEN FROM IRON ORE OR OTHER IRONBEARING MATERIALS IN THE SOLID STATE. Three different types of DRI are used in steelmaking: cold DRI, hot DRI, and hot briquetted iron (HBI). These DRI forms all provide flexible metallic charge materials for the various proprietary DRI processes. Most DRI processes use virgin iron ore in a gas-based shaft furnace, fueled by natural gas, syngas, hydrogen, or a mixture of these. The iron ore is heated...

GLOBAL SERVICE SUPPORT EXPERT GLOBAL SUPPORT FOR YOUR SpectraExact 2500 The robust and reliable SERVOTOUGH SpectraExact 2500 photometric analyzer uses non-depleting sensing technology and has low maintenance requirements. However, to ensure peak performance throughout its lifetime of operation, we recommend regular checks and parts replacement. Service check, calibration, and validation should be performed annually, along with regular checks of diagnostics, the condition of cell windows, source voltage, detector, etc. Scrubbers and seals should be replaced as required, while periodic...
