After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. The first step is the synthesis of oligomers (polymers with few repeating monomer units) from the linear alpha-olefin. Refined mineral oils often contain sulfurs, aromatics and other compounds that can erode the quality and consistency of a mineral oil. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. The plot below shows a comparison of the air release times exhibited by ISO VG 320 blends composed of our Synfluid mPAOs, and traditional HV PAOs with PAO 8 cSt. Group IIIB was unable to consistently pass the TDI or M111 tests.

High temperatures can thin and break down oil, crippling its lubricating ability, whereas low temperatures can rob a lubricant of its ability to reach critical parts. <>stream
III F challenge formulators, and their suppliers, to step up performance for the next generation of engine oils. endobj These oligomers are distilled and hydrogenated to yield specific molecular weight ranges that meet the viscosity grades that are desired. 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. No matter what the combination of additive or base oil, one thing is certain: When you begin with a higher-quality base oil, you will achieve a better formulation in the end. The chart below illustrates the relative effect base oils have on the operating temperatures in a modified four-ball machine. By utilizing this new process combined with the inherent properties of PAOs, a grease can be produced that can be used in both extreme high- and low-temperature applications. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. 102 0 obj Address new equipment conditions (higher operating temperature and pressure, greater loads and speed). It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. endobj If pour point is not a critical property in your application, then blending a PAO 5 and PAO 7 might give you that clear advantage that you are looking for. Regarding the A.O. With Synfluid PAO 4 cSt having a 73C ppt and 40C viscosity of 2,380 cSt, a PPD is not necessary. Two lubricants with the same VI may perform dramatically differently at low temperatures. These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines. 0000001332 00000 n
This is just one of the many performance advantages of Synfluid mPAO. Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. mary berry grandchildren names . PAO-based rotary screw compressor oil offers better performance in the compressor. PAO-based lubricants offer a significant advantage in oxidative stability. According to analysis conducted by Kline & Co., more than 78% of all lubricant requirements in the world annually are met with the use of mineral oil-based fluids. endobj Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene.

Two major types of synthetic basestockspolyalkylene glycols (PAG) and polyalphaolefin (PAO)and the lubricants formulated from them, will be compared. With todays oils requiring a higher-quality lubricant basestock to meet more stringent tests, polyalphaolefins are perfectly tailored and consistently manufactured to meet the challenge. Furthermore, we are able to achieve these properties with non-decene alpha olefin feedstocks while providing advantages over existing products and extending feedstock supply. During 2011, Chevron Phillips Chemical acquired PAO assets in Beringen, Belgium, and began mPAO production in Texas. However, not all synthetic lubricants are created equal. Both basestock types have low volatility and high fire points (when stabilized) for a given viscosity grade. Our unique PAO 2.5cSt further improves flash/fire points by as much as 10 percent over other commercial polyalphaolefins. PAG-based lubricants provide many property and performance advantages over mineral oil-based and other synthetic lubricants, as outlined in Table 2. Finally, greater oxidative stability extends oil life and keeps the compressor clean for a longer service interval. In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. xmp.did:F87F1174072068118083E936383AAE83 As temperature increases, a higher VI fluid will give increased fluid film thickness, which could result in lower wear. Synthetic lubricants can meet these demands because they perform better than mineral oil-based lubricants in many or all the critical performance areas: reduced wear and friction, resistance to sludge formation, lower volatility, greater corrosion protection, and improved thermal and oxidative stability. In terms of viscosity, there are tradeoffs in choosing one PAO over another: energy consumption (heat dissipation and production throughput) versus safety of operations (impacted by flash/fire points and volatility). With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability at high operating temperatures in addition to the low-temperature benefits for which they are known. 0000034554 00000 n

Sorry, we couldn't find anything that matched your search, PAO-based lubricants generally resist creep and water washout and offer good lubricity across a variety of substrate material pairings, including metal-to-metal and metal-to-plastic. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. Getting the air to release from the lubricant is vital to allowing the lubricant to do its job. 1. This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. Adobe PDF Library 10.0.1 However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. Compatible with seals and paint used with mineral oil, no need for change at all operating temperatures. Weve got you covered! The tests used below were the Cold Cranking Simulator for high shear (about 10-1 sec-1) and Brookfield viscosity for low shear (about 2 sec-1) each measured at -20C. The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others.

We look forward to helping you consolidate your grease cabinet! PAOs are considered a very pure substance since they are derived from petrochemically pure ethylene and then from 1-decene or 1-dodecene, which could be considered a further purification step. For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. The vast number of high-quality base oil choices can be daunting when trying to balance fuel efficiency and wear protection. It is true there are many high-quality base oils around, but the highest quality is still achieved when Synfluid PAOs are chosen. Conversely, if you reduce the temperature, the reaction rate decreases and the oil lasts longer, providing better protection. 0000000891 00000 n
