Analyzing various parameters in petroleum products is one of the most frequent requests in contract or quality control laboratories. Automation has gained popularity in the last decade due to the high number of tests required along with the use of aggressive solvents and reagents. Combined automated benchtop-based systems are available, but these still require operators to perform many manual ...

What is a lubricant? A lubricant is defined as a petroleum-derived product used to control and reduce the friction and wear of moving machinery parts (e.g., in engines and turbines). The main purpose of lubricants is to help protect and prolong the lifetime of the ...
Major tests of interest would be tests such as looking at additives (elemental spectroscopy) viscosity, infrared fluid integrity, particle count, total acid number (TAN), and total base number (TBN). Looking at all of the results together from various tests can indicate when a lubricant mix up has occurred. ...
There will often be a combined alarm system or something similar to, "six parts per million for a combination of chrome copper nickel iron combined", where the number must not reach the limit. It is another metric for having an extremely low number. ...
Naval Sealift Ship Puts Accuracy to the Test(This is an excerpt from a published article in the April 2013 issue of "Lubes 'N' Greases" magazine) The United States Naval Ship (USNS) Watson is one of the largest, medium-speed, roll-on, roll-off ships that have significantly expanded the nation’s sealift capacity. The Watson has a considerable amount of machinery, including main engines, ...
Chillers are used across a range of industries to remove heat from processes or from facilities. Some examples include commercial brewing operations that keep their entire brew houses near zero degrees Celsius or chemical processes that require a steady supply of chilled water for their ...
Pumps are used in industrial and fleet applications to move liquids and gases. Most pumps used in industrial applications are either positive displacement or centrifugal. In both cases bearings are the component that must be lubricated and monitored. Rotary positive displacement pumps have gears, screws, lobes or vanes which are also lubricated, usually by the fluid they are pumping, whether it ...
Water contamination should not exceed 0.25 % for most hydraulic systems. A number of new technologies are available to detect water contamination in lube oils, and on-site results correlate extremely well with laboratory techniques. ...
Monitoring turbines with oil analysis is well known and well established. All turbines, both steam and gas, have a large oil reservoir to lubricate the turbine bearings. Older designs had separate sumps for the hydraulic control of valves, whereas newer designs may have the lube oil and hydraulic sump linked together. Power plant operators new to oil analysis can be easily confused about what all ...
Oil analysis was first employed on engines as a predictive maintenance tool, and it remains a predominant technique for insuring the reliability of engine systems. Reciprocating internal combustion engines power most of the world's mobile equipment, such as cars, trucks, buses, locomotives, mining equipment, agricultural equipment and are also common in stationary backup power generators, oil and ...
Oil analysis is a very useful tool for gear systems. Geared systems are found across both mobile and industrial equipment. Though they are designed to be very reliable, they cause a lot of disruption and costs when they wear or break due to poor operation or contamination. Oil analysis is a great tool to detect when failure conditions are developing, and as such most gear manufacturers suggest ...
” The FluidScan Q1000 is a rugged, handheld infrared spectrometer that measures a range of key oil condition parameters including total acid number (TAN), total base number (TBN), oxidation, nitration, sulfation, additive depletion, incorrect lubricant, water, glycol, soot, glycerin and FAME in biodiesels ...
The best method to use depends on the application need. TOTAL ACID NUMBER A high concentration of acidic compounds in a lubricant can lead to corrosion of machine parts and clogged oil filters due to the formation of varnish and sludge. ...
Commercial pulverous activated carbon (AC-0) was modified through two steps: oxidize AC-0 acid firstly, impregnate it with iron using ferric chloride secondly. ...
TOTAL ACID NUMBER A high concentration of acidic compounds in a lubricant can lead to corrosion of machine parts and clogged oil filters due to the formation of varnish and sludge. ...
The bottom line: Emulsified water can cause oil to behave unexpectedly, and can cause rust, clog filters, and increase oil acidity Direct Effects Emulsified moisture has a direct effect in the compressibility of oil. ...
The effect of frontal–advance velocity on the total relative mobility at different concentration of polymer has been discussed. ...
