PAO-based lubricants offer a significant advantage in oxidative stability. You see, PAOs are carefully designed, not refined. There are multiple considerations when determining the best synthetic lubricant for a particular application, but knowledge of the general properties of the synthetic lubricant types being considered is the starting point. Process Chemical Compatibility Guide In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. Ethylene is produced by cracking either crude oil or natural gas. and PAO plays an integral part of meeting the challenge for top-tier oils. As oil volatilizes, the viscosity increase will result in poorer overall performance. 0000001605 00000 n polyalphaolefin compatibility chart. The lower volatility decreases oil replacement costs by reducing oil consumption. PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. 180 0 obj There are distinct advantages in volatility and low-temperature viscosity.

In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. 1 - High Resistance 2 - Limited Resistance 3 - No Resistance . News & Technology for the Global Energy Industry. The chart below shows the Noack volatility for both 1-decene and 1-dodecene based PAOs of varying viscosities. Youre not kidding! PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. The chart below illustrates how Chevron Phillips Chemical has come up with an economical solution to a VW T-4 engine test. Having a high viscosity index helps to protect an engine at temperature extremes. The chart below shows the effect of two different shear rate viscosity determinations on three different fluids (4 cSt at 100C) and the dramatic differences between them. Its estimated that over 100 million gallons of fluids leak from hydraulic machinery and other lubricant equipment in North America each year! The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. The differences in flash, fire, volatility and viscosity highlight the flexibility benefits of using a Synfluid PAO. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. PAG-based lubricants are commonly used in compressors, gearboxes, air conditioning systems, metalworking, quenching, and hydraulic systems where fire-resistance or environmental acceptability are required. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. Copyright 2023 Chevron Phillips Chemical Company LLC. 0000001216 00000 n This is the case for blending Synfluid PAO 5 and PAO 7. The Ethylene price in the Europe region was dull throughout the third quarter of 2022, which abetted the declining price trend of PAO throughout Q3 in Europe. However, unlike foaming, entrained air can be a difficult problem to treat with additives. The results indicate that the CSC 980 Tan grease has a running torque of 3.77 N-m versus 10.9 N-m for the same grease with an alternate base oil. General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. xref In addition to the low temperature performance demonstrated by CCS, the volatility and viscosity index of the PAO 5 and 7 blend are improved over traditional PAO 6. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. 0000016208 00000 n PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. xmp.did:F87F1174072068118083E936383AAE83 Heavier components adversely affect low-temperature performance and pour point. Whether its transportation or industrial lubes, greater fuel efficiency means lower operating costs. Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. Disadvantages of PAG-based lubricants are summarized in Table 3. This is just one of the many performance advantages of Synfluid mPAO. Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. polyalphaolefin compatibility chart. To mitigate this effect, We recommend taking a look at Synfluid PAO 5 and PAO 7, due to their excellent Noack volatilities of 5.5% and 2.3%, respectively. Group V oils also include esters and naphthenic oils.
