Lecture 3: Petroleum Refining Overview In this lecture, we present a brief overview of the petroleum refining, a prominent process technology in process engineering. 3.1 Crude oil Crude oil is a multicomponent mixture consisting of more than 108 compounds. Petroleum refining refers to the separation as well as reactive
Sep 21, 2007· Process Chemistry of Lubricant Base Stocks provides historical and conceptual background to the technologies used to make base stocks, thorough references, and a unique emphasis on chemical, not just engineering, aspects of lubricant processing—making this book an ideal and practical reference for scientists across a wide range of disciplines.
Synthetic oil is a lubricant consisting of chemical compounds that are artificially made. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials.The base material, however, is still overwhelmingly crude oil that is distilled and then modified physically and chemically.
Low speed pre-ignition (LSPI), a form of abnormal combustion that can lead to destructive super-knock in downsized engines, is a serious concern for several OEMs. Dr Cecile Pera, Infineum, Performance Testing Leader, discusses the potential link between lubricant combustion properties and LSPI mechanisms, which she presented recently at UNITI Mineral Oil Technology Congress.
a pool or it could be droplets of oil collected in a highly porous rock such as sandstone. An oil trap is a non-porous rock formation that holds the oil pool in place. Obviously, in order to stay in the ground, the fluids – oil and associated gas – must be trapped, so that they cannot flow to the surface of the earth.
Lynch, a consultant to the lubricants industry, provides an introduction to the chemistry behind the production of lubricant base stocks from crude oil fractions, as well as an overview of the development work that has gone on in this area over the past 150 years.
The lighter grades of crude oil produce the best yields of these products, but as the world's reserves of light and medium oil are depleted, oil refineries are increasingly having to process heavy oil and bitumen, and use more complex and expensive methods to produce the products required.

These base oils are at times mixed with other base stocks to enhance the oil's properties. An example would be a PAO-based compressor oil that is mixed with a polyolester. Esters are common Group V base oils used in different lubricant formulations to improve the properties of the existing base oil.

Jul 28, 2016· Lubricants Lubricants are those substances, which are Used to reduce the force of Friction between two sliding surfaces. 5. Lubrication Lubrication is the process, or technique employed to reduce wear on surfaces in close proximity, and moving relative to each another. 6.
Paraffin oil, like mineral oil, is a by-product from the petroleum distillation process. Paraffin based products are relatively non-reactive and have excellent oxidation stability. Paraffinic oils have relatively high wax content, high pour point, and typically a high viscosity index (VI).
This chemistry is the industry's premier base stock technology. Unlike conventional mineral-based chemistries, AMSOIL PAO base stocks contain fully saturated, hydrogenated molecules and are free of wax and other impurities.

lubricants, such as petroleum oils and polyalphaoleﬁns. Hence, any reduction in viscosity of UCON lubricants due to gas dissolution in the lubricant is minimal. Therefore, UCON lubricants maintain their viscosity better in intimate contact with gases, thus providing thicker lubricant ﬁlms and better lubrication. The beneﬁts of this

Lubricant quality improved significantly only when the additive chemistry improved. This was the only viable strategy until a significant improvement in base oil technology was available. Part 2 will explain how new hydroprocessing technologies opened the door for significant improvements in base oil quality and finished lubricant performance.

water used to make it. The speed of the reaction between the oil and the caustic soda is influenced by free fatty acid content of the oil, the heat of the components before mixing, and how vigorously the mixing is to be done. Free fatty acid contents, vigorous mixing, and heat, speed up the given soap-making process.
