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: NeSSITM is a success
Current work is focused on migration to NeSSITM Generation II systems
Example: SeTS: NeSSITM-Enabled Gas Sampling
OxygenSensor (GE)
MoistureAnalyzer (GE)
Static GasMixer (1/4” SS)
H.P.N2 Line ( 150 psi )
To mix with BTX fordilution and flushingsystem
• 4 Rails ( NeSSITM 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 )
