Oil Sampling Procedure RICE/NESHAP Data Interpretation Q&A
® SOPUS Products
Work with a valid work permit when required
Conduct gas tests when required
Verify isolation before work begins and use the specified life protecting equipment
Do not walk under a suspended load
Do not smoke outside designated smoking areas
No alcohol or drugs while working or driving
® SOPUS Products
Obtain authorization before entering a confined space
While driving, do not use your phone and do not exceed speed limits
Obtain authorization before overriding or disabling safety critical equipment
Protect yourself against a fall when working at height
Wear your seat belt
Follow prescribed Journey Management Plan
Use sampling valves Locate valves to be convenient and effective Allow enough operating time to evaporate condensation Train sampling personnel to ensure consistency
Get a representative sample!
® SOPUS Products
Sample cold system Drain-port sampling – whatever drains out Changing sampling methods and point Dirty sampling pathway Cross-contamination of sampling devices Waiting days (or weeks) before sending samples to lab
IMPACT OF NESHAP-RICE ON GAS ENGINE OIL ANALYSIS

•
National Emission Standards for Hazardous Air Pollutants (NESHAP) Reciprocating Internal Combustion Engine. (RICE) Subpart ZZZZ of the Code of Federal Regulations (40 CFR 63) addresses stationary RICE. Main criteria pollutants emitted: CO, Particulate Matter, NOx, VOC
® SOPUS Products
Rules applies to many stationary engines, but not all. Federal standards address maintenance practices based upon the assumption that a well maintained engine pollutes less. Regulations establish specific oil drain intervals based upon engine horsepower, location and method of operation. Operators have the choice to change oil at prescribed intervals or sample at that interval to demonstrate the oil is still suitable for use. If a sample exceeds ZZZZ limits, the operator is required to change the oil within 2 business days or shut the unit down.

Total Acid Number (TAN) Viscosity % Water Content by volume
Increases by more than 3.0 mg of potassium hydroxide per gram from TAN of the oil when new Changed by more than 20% from the viscosity of the oil when new >0.5
Oil Analysis must be performed at same frequency specified for oil changes If condemned, change oil within 2 business days

Regulators may ask for product baseline values during audits Confirm oil analysis laboratory is utilizing ZZZZ limits Make sure laboratory has correct product identification and baseline values ® SOPUS Products
Reproducibility = “Expected” variance when a single sample is tested multiple times Function of Test Method (Not laboratory) Measured by ASTM (American Society for Testing and Materials)
Shell LubeAnalyst verifies TAN via Elevated Oxidation/Nitration Retest All Samples Exceeding ZZZZ Limit
® SOPUS Products
Both Federal (EPA) and State regulators are actively conducting audits Proper sampling technique and “paperwork” preparation important Recordkeeping importance elevated Missed samples frowned upon Was oil changed when sample was taken? If it was, check the “Oil Changed” box Periodic database maintenance is recommended Designation of an oil analysis program administrator is encouraged

OIL ANALYSIS TESTS
® SOPUS Products
FTIR – Oxidation and Nitration – Oil degradation Water or Coolant content – Corrective action required Viscosity (D 445) – Oil degradation, contamination Elemental Analysis – Wear metals, additives and contaminants Total Acid Number – Oil degradation, acid formation
® SOPUS Products
Measures oil degradation resulting in oil thickening, engine lacquering (varnish) and deposits (ring area) Forms weak acids resulting in corrosion of bearings and oil cooler Limits the oil life
Attention level: 20 [abs/cm] Action level: 25 [abs/cm]
