If you are a fuel industry professional, you have probably noticed that oil analysis is an important part of your work. It helps you to determine the level of oil contaminants that are present in a given vehicle’s oil, and to set a baseline for what you should expect from your oil. Several parameters can be derived from this information, including expected viscosity grade, active additives, and acid/base number levels. This information is often overlooked, because it is not always present on oil sample labels and request forms. In addition to identifying contamination levels, elemental analysis is also used to determine additives and wear metals. It is also used to determine the degree of contamination, which is reported as parts per million (ppm).
Routine oil analysis measures many different things, including viscosity, elemental analysis, moisture levels, and particle counts. FTIR spectroscopy and acid number are also used to determine the condition of the oil. The results of these tests are recorded in a report called LubeScan. The report is an excellent source of information about the overall condition of the sample, as it indicates whether or not there have been any changes from previous analyses.
An oil analysis report will include the raw data and graphs to illustrate noteworthy trends. Graphs should also provide warning and alarm limits, which should be modified according to machine operating conditions, lubricant type, and reference data. For example, when there is an abnormal spike in the oil, an alarm should be issued. The next step is to analyze the cause of the problem. A detailed report will give you an idea of whether there is an underlying issue.
Analytical Ferrography examines particles’ size, shape, and color. It is the only oil analysis test that is specific enough to justify shutdowns, and requires a clean, sealed sample line. To conduct this analysis, you must use a high-quality sampling kit. Ensure that the fluid in the sample line moves throughout the system to avoid particle contamination. It’s best to use a return line back to the reservoir. Besides that, turbulent regions will enhance particle distribution.
Another important aspect of oil analysis is its total acid number. This indicates the amount of acid content in the oil. New oils contain additives that affect TAN numbers, and regular analysis at specific intervals is important to determine its performance. Low TBN is usually caused by improper application of the oil, as well as by waiting too long between oil changes. Also, it can be caused by overheating or using high-sulfur fuel. Besides oxidation, a low TBN may be indicative of the presence of other contaminants.
Infrared is a powerful technology used in oil analysis. It can give valuable information about oil characteristics, additive packages, and fluid identity. The response of oil to specific regions of the infrared spectrum is weighted according to the characteristic being studied. Typically, this type of analysis yields results that are more accurate than traditional methods. If you’re looking for a solution to a specific oil issue, infrared is the best way to go.
Oil analysis is an important part of modern condition monitoring programs. Oil samples are extracted from equipment at predetermined intervals and sent to a laboratory for analysis. The results can reveal vital information without cutting. The report can help your maintenance team make decisions based on the criticality of the machine and the impact of failure. Once you’ve made these decisions, you can move forward with lubrication activities. It’s easy to monitor equipment’s condition and identify the necessary maintenance tasks.
Another essential part of oil analysis is to determine whether or not a reservoir is economically viable. The analysis process itself requires an immense amount of data, including well logs and production volumes. This data will be used to inform multiple disciplines within the oil industry, such as petroleum engineers, technical managers, and economic analysts. If you’re in the oil industry, you’ll find this tool invaluable. The following are some of the steps in performing an oil and gas analysis.
Oil analysis can identify issues with new vehicles and diesel equipment. For instance, high metal levels in an oil sample can make you rethink your purchase. Oil analysis can also identify components that need repair, avoiding unrecoverable downtime. Using a specialized oil analysis can also help you safely extend drain intervals, which can help you save money on oil. But, ideally, an oil analysis program will provide you with comprehensive information and recommendations for the best solution for your car.
