Since the Roman era, many liquids, including water, have been used as lubricants to minimize the friction, heat, and wear between mechanical parts in contact with each other. Today, lubricating oil, or lube oil, is the most commonly used lubricant because of its wide range of possible applications. The two basic categories of lube oil are mineral and synthetic.

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. If you like you can make them yourself. Wouldn't you like that ride to last a little longer? Cold-pressing is the best process to produce carrier oils of high quality.

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. In the early days of the oil industry, lubricants The feedstocks that move into base oil production have alternative destinations in fuels operations and many of the by-products of base oil production move back to the fuels side for processing and blending. Some are predominantly naphthenes so yield a lubricating oil that is more sensitive to temperature changes than the paraffin-base crudes. A Canadian company has even developed a process to form micro wax and polymers into a structural material that does not require maintenance, in essence it is a wax brick.

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.

Such lubricant compositions are also referred to as SAE 0W-x compositions. The maximum low temperature viscosity requirement, VdCCS, is intended to facilitate engine starting or cranking in cold weather. To ensure pumpability the cold oil should readily flow or slump into the well for the oil pump, otherwise the engine can be damaged due to insufficient lubrication. The mini rotary viscosity MRV requirement is intended to ensure a minimum pumpability performance.

A series of articles dealing, in as simple a way as possible, with the basic facts of lubrication, lubricants, their selection and prescription, specification, application, and testing. This series is primarily intended for students, engineering personnel who may be unfamiliar with certain aspects and others who, one way or another, are interested in this important subject.

A LOOK AT LUBRICATING OILS

 Ты это уже. - Вот. Она нахмурилась. - Ты не заметил ничего. Ну, может, дошел какой-нибудь слушок. - Мидж, послушай.  - Он засмеялся.

 Разумеется. Как глупо с моей стороны. Прошу меня извинить.

Сигналы продолжались. Источник их находился где-то совсем близко. Сьюзан поворачивалась то влево, то вправо. Она услышала шелест одежды, и вдруг сигналы прекратились. Сьюзан замерла. Мгновение спустя, как в одном из самых страшных детских кошмаров, перед ней возникло чье-то лицо. Зеленоватое, оно было похоже на призрак.

Темнота стала рассеиваться, сменяясь туманными сумерками. Стены туннеля начали обретать форму. И сразу же из-за поворота выехала миниатюрная машина, ослепившая ее фарами. Сьюзан слегка оторопела и прикрыла глаза рукой. Ее обдало порывом воздуха, и машина проехала мимо.

 - В этом нет никакого смысла. Стратмор встал и начал расхаживать по кабинету, не спуская при этом глаз с двери. - Несколько недель назад, когда я прослышал о том, что Танкадо предложил выставить Цифровую крепость на аукцион, я вынужден был признать, что он настроен весьма серьезно.

Через некоторое время им с огромным трудом удалось расширить щель до одного фута. - Не отпускай, - сказал Стратмор, стараясь изо всех сил.  - Еще чуточку. Сьюзан удалось протиснуть в щель плечо.
