Such lubricant compositions are also referred to as SAE 0W-x compositions.
Base oils, unlike essential oils, don't contain a concentrated aroma but most of them have a mild distinctive smell and don't evaporate. Now this recent news from Amyris is pretty interesting since I used to cover a little bit of the base oil industry when I wrote articles for Chemical Market Reporter before on lubricants, greases and waxes. Those are a combination of a carrier oil, often sunflower, and plant material. OK, well nearly every situation.

Base oils are used to manufacture products including lubricating greases , motor oil and metal processing fluids. Different products require different compositions and properties in the oil. Whether or not a crude oil is suitable to be made into a base oil is determined by the concentration of base oil molecules as well as how easily these can be extracted. Base oil is produced by means of refining crude oil. This means that crude oil is heated in order that various distillates can be separated from one another.
This invention relates to an improved method of preparing base stocks for lubricating oil with improved color, thermal and oxidative stability. More particularly, it relates to an improved method of preparing base stocks for lubricating oil with improved color, thermal and oxidative stability by varying the temperatures and pressures of the hydrofinishing process. It is well-known that lubricants are susceptible to deterioration by oxidation. Lubricants can be attacked by oxygen or air at high temperatures to form heavy dark viscous sludges, varnish and resins. Such deterioration reduces a lubricant's effectiveness to perform its required task. Accompanying the deterioration of lubricants by oxidation is the resultant corrosion of the metal surfaces for which such lubricants were designed to protect. Acids develop from the sludges and resins which are corrosive enough to destroy most metals.
Bull, S. A hydrotreating process for manufacturing lube oils of HVI quality or better has been developed and implemented on a commercial scale. Development included catalyst optimization, selection of operating conditions and evolution of product specifications. The process operates at moderate hydrogen pressure and has been proved in seven years' commerciai operation. Extensive product development has shown that hydrotreated base oils give products at least equal in performance to those based on extracted oils, with notable advantages in some applications.

Most products of Crude oil processing are usually grouped into three categories: light distillates LPG, gasoline, naphtha , middle distillates kerosene, diesel , heavy distillates and residuum fuel oil, lubricating oils, wax, tar. You have to separate the different types of hydrocarbons to have anything useful.
Самая грязная ванна, какую мне доводилось видеть. И самый мерзкий пляж, покрытый острыми камнями. Этого и ждут от меня читатели. Больные на соседних койках начали приподниматься, чтобы разглядеть, что происходит. Беккер нервно посматривал на медсестру.
Я отказался взять кольцо, а эта фашистская свинья его схватила. Беккер убрал блокнот и ручку. Игра в шарады закончилась. Дело принимает совсем дурной оборот. - Итак, кольцо взял немец. - Верно. - Куда он делся.
Че-че-го же вы хотите? - выдавил он заикаясь. - Я ничего не знаю. Беккер зашагал по комнате. - На руке умершего было золотое кольцо. Я хочу его забрать. - У м-меня его .
Раздался страшный треск, и стеклянная панель обдала ее дождем осколков. Звуки шифровалки впервые за всю историю этого здания ворвались в помещение Третьего узла. Сьюзан открыла .
