00:00:49.040 today the whole world moves on a thin 00:00:52.07000:00:52.080 film of lubricating oil oil is our magic 00:00:55.85000:00:55.860 carpet without it nor wheel could turn 00:00:58.25000:00:58.260 no moving part operate delicate watches 00:01:02.17000:01:02.180 and ponderous engines 00:01:06.95000:01:06.960 watercraft and aircraft an automobile 00:01:15.12000:01:15.130 trucks 00:01:18.60900:01:18.619 busses and tractors whatever there is 00:01:23.10900:01:23.119 motion wherever power is made or used 00:01:25.56900:01:25.579 there's oil 00:01:30.45000:01:30.460 lubricating oil separates spinning gears 00:01:33.00000:01:33.010 and metal parts lacking it's all moving 00:01:35.94000:01:35.950 mechanisms would soon grind to a stun 00:01:41.42000:01:41.430 with it they move smoothly efficiently 00:01:45.20000:01:45.210 provide proper lubrication is not simple 00:01:48.12000:01:48.130 or easy in this stage of machines many 00:01:51.45000:01:51.460 types of oil are needed each to perform 00:01:53.79000:01:53.800 a special job only in the great modern 00:01:57.69000:01:57.700 refinery can these many types be 00:01:59.85000:01:59.860 perfected here modern science keeps pace 00:02:02.88000:02:02.890 with the ever increasing ever more 00:02:04.56000:02:04.570 exacting needs for lubricating oil 00:02:09.41900:02:09.429 so we come to the story of how we get it 00:02:12.11900:02:12.129 and what we do to it the hero of our 00:02:15.72000:02:15.730 story is a typical lubricating oil 00:02:17.88000:02:17.890 molecule 00:02:19.50000:02:19.510 he is called a hydrocarbon because he is 00:02:22.74000:02:22.750 made up of atoms of carbon and hydrogen 00:02:25.16000:02:25.170 joined together such molecules and 00:02:29.36900:02:29.379 countless other hydrocarbon molecules 00:02:32.14900:02:32.159 differing only in size and shape make up 00:02:35.39900:02:35.409 crude oil these molecules are much too 00:02:38.61000:02:38.620 small to see even with the highest 00:02:40.44000:02:40.450 powered microscope but are tremendous in 00:02:43.11000:02:43.120 importance 00:02:44.05900:02:44.069 let's take our typical lubricating oil 00:02:46.89000:02:46.900 molecule and trace his career from the 00:02:49.05000:02:49.060 time science begins to prepare him for 00:02:51.42000:02:51.430 his role in our mechanized world as with 00:02:54.83900:02:54.849 all petroleum products lubricating oil 00:02:57.03000:02:57.040 comes from crude oil crude oil of 00:02:59.75900:02:59.769 veritable black magic that is taken from 00:03:02.58000:03:02.590 the depths of the earth 00:03:03.90000:03:03.910 [Music] 00:03:07.98000:03:07.990 the first step is that of separating the 00:03:10.47000:03:10.480 various types of molecules 00:03:12.39000:03:12.400 this is accomplished at the refinery in 00:03:14.85000:03:14.860 the huge bubble towers of a pipe still 00:03:17.34000:03:17.350 by distillation here's a simplified 00:03:21.33000:03:21.340 diagram and we really mean simplified of 00:03:24.51000:03:24.520 a modern distillation unit the crude oil 00:03:27.27000:03:27.280 is heated on the left so hot that most 00:03:29.79000:03:29.800 of it is above its boiling point and so 00:03:32.13000:03:32.140 it turns to vapor it then goes to the 00:03:34.41000:03:34.420 bubble tower on the right 00:03:36.48000:03:36.49000:03:39.86000:03:39.870 the gas molecules are small they have 00:03:43.05000:03:43.060 little tendency to condense from gas to 00:03:45.33000:03:45.340 liquid and so they pass all the way up 00:03:47.79000:03:47.800 the tower and are taken out at the top 00:03:52.28000:03:52.290 the next larger molecules are gasoline 00:03:55.72000:03:55.730 they rise to the fourth level before 00:03:58.36900:03:58.379 they change from vapor back to liquid 00:04:00.31900:04:00.329 and are drawn off 00:04:03.55900:04:03.569 the kerosene molecules have condensed on 00:04:06.35000:04:06.360 the next Lord train and fuel oil from 00:04:09.55900:04:09.569 the one still lower the unbaptized 00:04:12.94900:04:12.959 portion known as reduced crude is 00:04:15.70900:04:15.719 removed from the bottom of the tower and 00:04:17.65900:04:17.669 sent to a second still a lubricating oil 00:04:23.48000:04:23.490 pipes still for the critical task of 00:04:26.09000:04:26.100 properly separating the lubricating oil 00:04:28.21900:04:28.229 molecules high temperature is ordinarily 00:04:31.46000:04:31.470 required to distill these heavy 00:04:33.20000:04:33.210 molecules are avoided by the use of 00:04:35.36000:04:35.370 vacuum and steam this bubble tower 00:04:39.08000:04:39.090 further separates the molecules into 00:04:41.24000:04:41.250 light medium and heavy distilled lube 00:04:43.40000:04:43.410 oil stocks from the bottom of the tower 00:04:46.04000:04:46.050 is taken residual loom stock containing 00:04:48.49900:04:48.509 asphalt and other heavy materials to 00:04:54.43900:04:54.449 keep things simple we've shown just four 00:04:56.54000:04:56.550 types of lubricating oil molecules as 00:04:59.48000:04:59.490 they come from the stills other 00:05:01.04000:05:01.050 materials come along with them and as so 00:05:05.06000:05:05.070 often happens in the best of families 00:05:07.01000:05:07.020 these other members may be black sheep 00:05:09.89000:05:09.900 some of them have their uses but not in 00:05:13.01000:05:13.020 lubricating oil 00:05:14.55000:05:14.56000:05:29.41000:05:29.420 [Applause] 00:05:37.42000:05:37.430 I'm a color impurity 00:05:41.28000:05:41.290 under certain conditions these black 00:05:43.81000:05:43.820 sheep will interfere with good 00:05:45.37000:05:45.380 lubrication they must therefore be 00:05:47.44000:05:47.450 removed 00:05:50.09000:05:50.100 we'll start by getting rid of asphalt 00:05:52.49000:05:52.500 which has been concentrated in the 00:05:54.98000:05:54.990 residual stock that was taken off from 00:05:57.32000:05:57.330 the bottom of the second still 00:06:07.92000:06:07.930 asphalt is removed in units like this 00:06:10.80000:06:10.810 the oil is diluted for the liquefied 00:06:13.63000:06:13.640 petroleum gas called propane which has 00:06:16.60000:06:16.610 to be kept liquid by high pressure 00:06:18.19000:06:18.200 because of the temperature employed the 00:06:21.88000:06:21.890 large asphalt molecules are not soluble 00:06:24.31000:06:24.320 in the warm propane diluted oil they 00:06:26.98000:06:26.990 settle to the bottom and are drawn off 00:06:30.03000:06:30.040 saw the first steps in the refining 00:06:32.80000:06:32.810 process have been taken the process is 00:06:35.62000:06:35.630 used from here on may be applied to 00:06:37.87000:06:37.880 distilled as well as residual oils so 00:06:43.63000:06:43.640 for the sake of simplicity let's combine 00:06:45.49000:06:45.500 the distilled stalks then take the 00:06:48.67000:06:48.680 representative oil molecules that typify 00:06:51.34000:06:51.350 distilled and residual lubricating oil 00:06:53.80000:06:53.810 stocks and consider them as a typical 00:06:59.38000:06:59.390 lubricating oil molecule the little 00:07:01.87000:07:01.880 character whose to be are here all for 00:07:03.88000:07:03.890 the remainder of the story as we can see 00:07:08.44000:07:08.450 undesirable companions are still 00:07:10.60000:07:10.610 following him around 00:07:11.98000:07:11.990 and these undesirables will have to be 00:07:14.29000:07:14.300 removed before our hero can do his job 00:07:16.33000:07:16.340 properly the purifying process continues 00:07:21.70000:07:21.710 with the removal of wax little guy 00:07:27.43000:07:27.440 accepted low-temperature as money 00:07:29.41000:07:29.420 solidifies and blocks oil flow 00:07:32.29000:07:32.300 he is removed in units like this in 00:07:35.80000:07:35.810 these modern methods of dewaxing 00:07:37.81000:07:37.820 a thinner or solvent is added to the oil 00:07:40.63000:07:40.640 the thinner employed is liquefied 00:07:42.70000:07:42.710 propane normally a gas the same 00:07:45.31000:07:45.320 liquefied gas used in removing asphalt 00:07:47.95000:07:47.960 but now at a much lower temperature 00:07:53.22000:07:53.230 here is how this solvent dewaxing works 00:07:55.89000:07:55.900 the mixture oil and propane is chilled 00:08:05.07000:08:05.08000:08:06.44000:08:06.450 this causes wax molecules to form solid 00:08:09.96000:08:09.970 particles but the oil molecules remain 00:08:12.57000:08:12.580 liquid and easily passed through filters 00:08:14.76000:08:14.770 the wax particles which are solid cannot 00:08:17.91000:08:17.920 pass and are trap 00:08:20.04000:08:20.05000:08:21.29000:08:21.300 in settling tanks petrolatum a different 00:08:24.75000:08:24.760 type of wax contained in the residual 00:08:26.73000:08:26.740 oils is separated from the chilled 00:08:28.92000:08:28.930 mixture 00:08:32.85000:08:32.860 laboratory pour tests are continually 00:08:35.64900:08:35.659 run to make sure that the process is 00:08:37.48000:08:37.490 just described will produce oils that 00:08:39.73000:08:39.740 flow readily in cold weather so asphalt 00:08:46.15000:08:46.160 and wax are now gone a good start in our 00:08:48.87900:08:48.889 refining process the next two culprits 00:08:52.24000:08:52.250 to be dealt with by the character that 00:08:54.91000:08:54.920 forms sludge and varnish and the one 00:08:58.00000:08:58.010 that causes oil to thin excessively at 00:09:00.25000:09:00.260 high temperatures and thicken too much 00:09:02.31900:09:02.329 at low temperature they may be removed 00:09:06.93900:09:06.949 along with part of the color by several 00:09:09.61000:09:09.620 processes one is acid treatment sulfuric 00:09:13.50900:09:13.519 acid and oil are mixed together by 00:09:16.75000:09:16.760 chemical reaction acid particles hook on 00:09:19.12000:09:19.130 to the unwanted molecules forming heavy 00:09:21.61000:09:21.620 sludge that settles out of the oil 00:09:29.28000:09:29.290 another method is solvent extraction one 00:09:32.18900:09:32.199 of the most advanced processes 00:09:33.74900:09:33.759 revolutionary in principle making 00:09:36.09000:09:36.100 possible the attainment of new high 00:09:37.80000:09:37.810 standards in lubricating oil quality 00:09:42.67000:09:42.680 in this process a special solvent 00:09:45.40000:09:45.410 literally dissolves out unstable 00:09:47.41000:09:47.420 materials it differs from acid treatment 00:09:49.84000:09:49.850 in that no chemical reaction is involved 00:09:57.80000:09:57.810 the oils five stability resulting from 00:10:00.29000:10:00.300 solvent extraction is checked by the 00:10:02.09000:10:02.100 Indiana 00:10:02.84000:10:02.850 stirring oxidation test which measures 00:10:05.42000:10:05.430 the oils greatly improved resistance to 00:10:07.81900:10:07.829 attack by oxygen over long periods of 00:10:10.40000:10:10.410 time 00:10:12.73000:10:12.740 to demonstrate another improvement 00:10:14.32000:10:14.330 obtained by solvent extraction note that 00:10:17.74000:10:17.750 at room temperature the falling balls 00:10:19.54000:10:19.550 show that these two oils have the same 00:10:21.67000:10:21.680 viscosity or body 00:10:25.37000:10:25.380 but when they are chilled the oil on the 00:10:28.22000:10:28.230 right thickens less showing that its 00:10:31.28000:10:31.290 body is affected least by low 00:10:33.53000:10:33.540 temperatures this resistance to change 00:10:38.48000:10:38.490 is one of the desirable characteristics 00:10:40.10000:10:40.110 that is found in oils for the high 00:10:42.44000:10:42.450 viscosity index called bi files with 00:10:49.52000:10:49.530 high VI also better resist changes in 00:10:52.79000:10:52.800 body when heated 00:10:55.54000:10:55.550 thus lubricating oil is improved in its 00:10:58.61000:10:58.620 VI with the removal of the unwanted 00:11:00.95000:11:00.960 molecules by the solvent extraction 00:11:03.38000:11:03.390 process 00:11:04.05000:11:04.06000:11:11.45000:11:11.460 and now we have only one undesirable 00:11:14.46000:11:14.470 left he's not so bad but he does give 00:11:17.88000:11:17.890 oil a darker color to remove him 00:11:22.01000:11:22.020 lubricating oil is treated with a 00:11:24.12000:11:24.130 powdered special type of clay there's 00:11:27.09000:11:27.100 several ways to do this final cleanup 00:11:29.90000:11:29.910 one is to pump through a filter oil and 00:11:33.36000:11:33.370 powdered clay that have been mixed 00:11:34.98000:11:34.990 together another way is the percolation 00:11:39.63000:11:39.64000:11:42.17000:11:42.180 the oil descends slowly by gravity 00:11:44.72000:11:44.730 through a deep bed of a special granular 00:11:47.09000:11:47.100 type of clay clay particles hold tightly 00:11:52.37000:11:52.380 onto the dark color impurities the rest 00:11:54.98000:11:54.990 of the oil goes on through 00:11:57.24000:11:57.25000:12:00.49000:12:00.500 the improved lighter color is checked 00:12:03.20000:12:03.210 for uniformity by comparison with 00:12:05.18000:12:05.190 official color standards 00:12:08.84000:12:08.850 now our hero rid of his questionable 00:12:11.97000:12:11.980 companions by these purifying processes 00:12:14.43000:12:14.440 is at last fed for lubricating service 00:12:17.13000:12:17.140 under all except the most severe 00:12:19.01900:12:19.029 conditions out of the refining processes 00:12:26.22000:12:26.230 you've seen have come all these oils the 00:12:29.63900:12:29.649 rising bubbles indicate differences in 00:12:31.76900:12:31.779 body and the various colors differences 00:12:34.29000:12:34.300 in type these oils and thousands more 00:12:37.82900:12:37.839 are especially fitted for the countless 00:12:40.01900:12:40.029 variety of lubrication jobs so essential 00:12:43.01900:12:43.029 to our modern mechanized world 00:12:46.03000:12:46.04000:12:51.53000:12:51.540 into service they go 00:12:54.80000:12:54.810 specific answers to a wide range of 00:12:58.04000:12:58.050 lubrication requirements each one fitted 00:13:01.37000:13:01.380 to do a particular job 00:13:05.75000:13:05.760 in industry and transportation in 00:13:11.03000:13:11.040 devices at our homes and in countless 00:13:13.67000:13:13.680 other ways 00:13:18.10000:13:18.110 we know that on our farms now highly 00:13:20.74000:13:20.750 mechanized lubricating oil is extremely 00:13:23.29000:13:23.300 important in reducing friction 00:13:24.88000:13:24.890 preventing wear and rusty vitally 00:13:27.79000:13:27.800 helping the operation of all equipment 00:13:31.82000:13:31.830 but to meet increasingly severe 00:13:33.68000:13:33.690 operating conditions especially in motor 00:13:36.25900:13:36.269 cars trucks buses and tractors 00:13:40.78000:13:40.790 lubricating oils now need qualities that 00:13:43.49000:13:43.500 cannot be secured even by the best 00:13:45.80000:13:45.810 refining processes from oil alone 00:13:48.94000:13:48.950 scientists keeping pace with these new 00:13:51.05000:13:51.060 requirements have discovered that 00:13:52.43000:13:52.440 putting in special ingredients called 00:13:54.31900:13:54.329 additives even in small amounts makes 00:13:57.07900:13:57.089 lubricating oil work still better 00:14:00.40000:14:00.410 for certain conditions a poor point 00:14:03.01000:14:03.020 depressor a viscosity index improvers 00:14:05.50000:14:05.510 may be required in oils that transmit 00:14:07.75000:14:07.760 power for example in automatic 00:14:09.97000:14:09.980 transmissions oils must not vary greatly 00:14:11.92000:14:11.930 in body at different temperatures an 00:14:15.43000:14:15.440 anti-corrosion additive may be necessary 00:14:17.44000:14:17.450 to prevent corrosion of this type with a 00:14:19.75000:14:19.760 newer harder bearings 00:14:24.22000:14:24.230 an extreme pressure additives used where 00:14:27.13000:14:27.140 the pressure is extremely high and there 00:14:29.11000:14:29.120 is considerable rubbing between steel to 00:14:31.12000:14:31.130 steel surfaces as in hypoid gears it 00:14:34.57000:14:34.580 forms on these surfaces a tightly bound 00:14:36.70000:14:36.710 protective film and 00:14:40.48000:14:40.490 oiliness additive is used in mechanisms 00:14:43.36000:14:43.370 where the rubbing action requires an 00:14:44.95000:14:44.960 exceptionally strong film of oil 00:14:49.24000:14:49.250 an antioxidant may be employed to 00:14:52.44900:14:52.459 protect the oil at high temperature 00:14:54.16000:14:54.170 against the formation of sludge varnish 00:14:56.49900:14:56.509 and corrosive acids the detergent 00:14:59.41000:14:59.420 dispersant may be added to prevent the 00:15:01.11900:15:01.129 posits such as these from collecting in 00:15:03.00900:15:03.019 oil passages and to keep carbon and 00:15:05.61900:15:05.629 other deposits in a harmless finely 00:15:07.78000:15:07.790 divided state dispersed in the oil 00:15:11.73000:15:11.74000:15:13.37000:15:13.380 anteye foam agents for veterans from 00:15:16.44000:15:16.450 forming out of the equipment may 00:15:18.12000:15:18.130 sometimes be necessarily 00:15:24.96000:15:24.970 other antioxidants and also metal 00:15:27.75000:15:27.760 deactivators may be used to counteract 00:15:30.00000:15:30.010 the tendency of certain metals that may 00:15:32.19000:15:32.200 be present to promote attack on the oil 00:15:34.20000:15:34.210 by oxygen 00:15:37.95000:15:37.96000:15:40.71000:15:40.720 there are other additives for others 00:15:42.81000:15:42.820 special uses and new additives are being 00:15:45.30000:15:45.310 developed continually as new needs arise 00:15:49.76000:15:49.770 so now we see our fully finished 00:15:52.23000:15:52.240 lubricating oil molecule when required 00:15:55.26000:15:55.270 palliative spent in to handle the 00:15:57.12000:15:57.130 toughest lubrication problems tested and 00:16:07.41000:16:07.420 retested every step of the way our 00:16:09.90000:16:09.910 little lubricating oil molecule 00:16:11.52000:16:11.530 undergoes many final inspections before 00:16:14.25000:16:14.260 he is sent out to do his job 00:16:19.45000:16:19.460 like a fighter before his entry into the 00:16:22.25000:16:22.260 ring the oil undergoes many final checks 00:16:27.35000:16:27.360 body or viscosity is tested by the 00:16:30.96000:16:30.970 seybolt universal method 00:16:34.24000:16:34.250 or by the suspended level men from his 00:16:38.35000:16:38.360 viscosity at various temperatures his 00:16:40.75000:16:40.760 viscosity index or VI is calculated 00:16:45.09000:16:45.100 hydrometers are used to determine the 00:16:47.29000:16:47.300 gravity from which the weight per gallon 00:16:49.12000:16:49.130 may be calculated the Cleveland open cup 00:16:53.05000:16:53.060 flash test is another of the common 00:16:55.09000:16:55.100 control tests another is the ability of 00:16:58.84000:16:58.850 the oil to separate from water 00:17:00.57000:17:00.58000:17:02.82900:17:02.839 this is checked by the demon civility 00:17:05.60000:17:05.610 test that specified temperatures using 00:17:08.12000:17:08.130 mechanical agitation 00:17:12.33000:17:12.340 and by this test using steam 00:17:17.72000:17:17.730 tendency to form carbon is shown by this 00:17:20.21000:17:20.220 carbon residue test or by this more 00:17:22.81900:17:22.829 modern Ramsbottom method an excellent 00:17:27.11000:17:27.120 check on carbon forming tendency is 00:17:29.21000:17:29.220 obtained by distilling the oil under a 00:17:31.51900:17:31.529 high vacuum 00:17:35.13000:17:35.140 and collecting and measuring the 00:17:36.84000:17:36.850 combustion residue formed in the engine 00:17:38.91000:17:38.920 is of course the ultimate test service 00:17:44.43000:17:44.440 in the field is after all the best way 00:17:47.13000:17:47.140 to prove the practical worth of a 00:17:48.96000:17:48.970 product 00:17:50.98000:17:50.990 that is why the products of the research 00:17:53.16900:17:53.179 and development laboratories must also 00:17:55.65900:17:55.669 pass service tests before they offered 00:17:58.14900:17:58.159 for sale all lubricating oils and this 00:18:01.87000:18:01.880 includes power plant and industrial 00:18:03.94000:18:03.950 types and all automotive types must 00:18:07.69000:18:07.700 prove themselves on the firing line of 00:18:09.85000:18:09.860 practical use or little hero cruises 00:18:13.48000:18:13.490 Fitness proves he can take punishment 00:18:17.46000:18:17.470 months of severe performance are now 00:18:19.93000:18:19.940 compressed into a few hours by the use 00:18:21.90900:18:21.919 of ingenious speed-up tests the ability 00:18:26.98000:18:26.990 of an extreme pressure lubricant to 00:18:28.72000:18:28.730 protect metal against scouring in 00:18:30.54900:18:30.559 service is checked quickly with special
