CVI’s Oscillating Piston Technology

Constant piston motion keeps • sample fresh• sensor clean

No seals, one moving part

Proprietary electronics measure absolute viscosity from piston cycle time. Complies with ASTM D7483

Fluid enters measurement chamber

Temperature detector

Trailing coil tracks pistonelectro-magnetically

Lead coil sets up magnetic field to drive the piston

Coils switch when piston moves by detect point

Strengths of the Oscillating Piston Technique

• Known Accuracy (ASTM D7483)• Rugged Construction • Minimal Installation Costs• Low Maintenance Interval• Self Cleaning• Stable - Holds Calibration • Small Volume• Measurement and Report software provides

statistically verifiable results• Fast results• The ONLY ASTM recognized method that utilizes the

same technique for both process and lab applications

CVI Applications in Black Oils

Refining Operations – production control blending– Asphalt Refining – Lube Oil Refining

• Light, Medium, Spindle, Heavy– Combustible Oils - Diesel & HFO Refining –Viscosity drives in-line blending to hit quality

targets efficiently

Service Operations– Power Generation - Burning HFO

Viscosity control optimizes burn efficiency– Lube Oil monitoring in rotating equipment

Viscosity monitoring prevents premature equipment failures

10

Meeting QA Challenges

• Monitor with ASTM consistent instrumentation > in-line and in the lab

• Reduce labor costs with in-line real time monitoring with periodic lab checks

• Meet tighter product quality standards• Utilize simple to install in-line process instrumentation

• Lower maintenance costs – self cleaning sensors

CVI Viscometers use the same technology for lab & process – all ASTM consistent, producing accurateand repeatable results

11

CVI Monitoring Black Oils

In-Line Applications:• Installed in bypass lines with conditioning to meet lab results: • - flow control• - temperature control (insulated, heat traced, etc.)• - particulate filtering (in some cases)• Controlling temperature is essential for accurate viscosity information

(or TCV is used if process temperature is different from lab)• Some bypass lines routed through temperature control systems

Lab Applications:• Refineries are now using CVI lab viscometers for quality checks

Challenges of On-Line Viscosity Measurement

16

Conclusion: Real Time Compliments Lab

Internationally accepted lab tests are required Lab challenges:

Samples are not necessarily representative of instantaneous production.

Samples are subject to off-gassing and other changes between the time they are taken and analysis is performed.

Sampling and testing are labor intensive and time consuming, which delays corrective action

Real time data monitoring Extends laboratory analysis Lab is a snap shot Real time monitoring is a continuous view

Improves Quality Control Reduces testing demand on labs: labs can be used only for final

QC

Results = improved efficiency from in-line viscosity monitoring/control
