Deployment in ExxonMobil Operating plants and research sites Purchase in small quantities Can accept some risk by maintaining existing sample system as backup Able to test ideas, components Major projects Large quantities purchased Risk averse / use proven designs only Can take most advantage of standard designs –Engineering cost savings first duplicate design saves more than 50% of the engineering cost –Manufacturing cost savings first duplicate construction saves 10-20% of labor due to repetitive tasks
Deployment in ExxonMobil Multiple sites using modular components today Gas and liquid streams, up to diesel Superior performance to traditional designs: easier maintenance, fewer leaks Smaller surface area, less absorption effects Faster reconfiguration to new processes A major project in Asia Pacific will have Gen I and proven Gen II technology Will use modular technology on all streams where it has been shown to work at our plant sites (>95% of applications; >200 systems) Will use Gen. II components and connectivity, assuming testing is successful Testing of Siemens Gen II systems is underway Tests to be run on process streams, important applications SAAI supplying these systems in support of project work Testing of the modular sample system concept is complete at ExxonMobil: NeSSI TM is a success Current work is focused on migration to NeSSI TM Generation II systems
Example: SeTS: NeSSI TM -Enabled Gas Sampling Oxygen Sensor (GE) Moisture Analyzer (GE) Static Gas Mixer (1/4” SS) H.P. N2 Line ( 150 psi ) To mix with BTX for dilution and flushing system 4 Rails ( NeSSI TM Stick ) Mass Flow Controllers Temperature Probes Contain components to analyze gas mixtures Control gas flows (0-1liter/min), (0-100sccm), ( 0-10sccm), (0-2sccm) Sensor Ports ( measures dew/ frost points over a range of -110 to +60 C) (-166 to +140 F ) Slide courtesy of Cornelius Brons (ExxonMobil Research and Engineering Company)
