Effective Mooring Revision

Agents which markedly lower the interfacial tension between oil and water or other liquid, thus permitting them to mix or form emulsions. Lecithin and mono and diglycerides are emulsifiers derived from fats and oils and are widely used in food products (margarines, shortenings, salad dressing, frozen desserts, peanut butter, candy etc). Emulsifiers may also have other useful properties such as crystal modification and complex formation. The surface activity of these compounds depends on their molecular structure. They are compounds consisting of a non-polar and a polar group. The non-polar group is usually a hydrocarbon chain, such as fatty acids, which has an affinity for oils (lipophilic or hydrophobic), while the polar group is usually a polyol such as glycerol and has affinity for water (hydrophilic or lipophobic). Emulsifiers may be thought of as tadpoles, with the polar head anchored in the water phase, while the long hydrocarbon tail remains dissolved in the oil. The physico-chemical nature of the two groups governs the degree of affinity of the surfactant for oil or water.

Additives that allow oils to be mixed with water and water to be mixed with oils. They alter the surface properties of materials they contact because of their amphiphilic nature. That is to say, they have chemical affinity to both lipid and aqueous phases. Because of this property, the molecules become oriented along the surfaces or interfaces of these normally immiscible substances.

Erucic acid consists of a 22 carbon chain with one double bond on the thirteenth carbon atom. It is a major component of seed oils of the brassica family such as rapeseed or mustard seed. High levels of erucic acid in the diet have been found to have undesirable nutritional effects in animal feeding trials. In consequence, plant breeders have developed low and zero erucic acid content rapeseed, which has been commercialised. A high erucic rapeseed oil is used as a mould lubricant in the continuous casting of steel; erucamide, derived from rapeseed oil is an anti-blocking and slip agent in polythene films.

Any of a class of organic compounds made from the chemical reaction between an alcohol and an organic acid.

The ester value is the number of milligrams of potassium hydroxide required to saponify the neutral oil in one gram of fat. It is equal to the saponification value minus the acid value.

The reaction by which esters are formed from alcohols and acids, usually in the presence of an acidic catalyst, or with the more reactive acid anhydrides or chlorides for which no catalyst is required. Esters can also be changed to other ester by alcoholysis, acidolysis and interesterification.

Ethylene

A gaseous hydrocarbon, the second most important constituent of natural gas, it also occurs dissolved in petroleum oils and as a by-product of oil refinery operations and of the carbonization of coal. Ethane is a major raw material for the huge ethylene petrochemical industry, which produces such important products as polyethylene plastic, ethylene glycol, and ethyl alcohol.

Ethanol, also known as ethyl alcohol is manufactured by synthesis from ethylene. It is an oxygenated hydrocarbon used in a wide variety of high performance solvent applications (toiletries and cosmetics, paints, lacquer thinners, printing inks, dyes, detergents, disinfectants and pharmaceuticals), as a chemical raw material for the production of a range of monomers and solvents, and is essential in pharmaceutical purification. In transportation, ethanol is used as a vehicle fuel by itself, blended with gasoline, or as a gasoline octane enhancer and oxygenate.

Ethanolamines are prepared by the reaction of ammonia and ethylene oxide. They include monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA). The three are widely used in industry, principally as absorbents for acidic components of natural gas and of petroleum-refinery gas streams. MEA is mainly used as the raw material to produce ethyleneamines. It is also used to make detergents, metalworking fluids, and as gas sweetening. DEA is mainly used as gas sweetening and in agrochemicals. TEA is used in detergents and cosmetics applications and as a cement additive.

See Ethylene

Ethers, like alcohols and phenols are oxygenated derivatives. An ether has two hydrocarbon groups bonded to the oxygen atom. Diethyl ether (also called simply ether) is the most common variety. It is widely used as a solvent and as a volatile, combustible starting fluid for engines. Methyl-tert-buthyl-ether (MTBE) is used in gasoline to boost the octane rating and to decrease the toxic emissions in the exhaust.

A volatile ester used as solvents for resins, lacquers, paints, and varnishes.

Ethylbenzene is formed by combination of ethylene and benzene, and is then dehydrogenated to styrene for use in the production of plastics and synthetic rubber. For more information click website.

Also called ethene, ethylene is the simplest member of the olefinic hydrocarbon series and one of the most important raw materials of the organic chemical industry. It occurs in both petroleum and natural gas, but the bulk of the industrial material is produced by heating of higher hydrocarbons. Ethylene can be polymerized to the plastic material polyethylene, reacted with oxygen to give ethylene oxide, or with benzene to give ethylbenzene.

Ethyleneamines are organic compounds essential in the manufacture of a wide range of products from detergents, paints and fuel oils to pharmaceuticals, soaps, asphalt and paper. Ethyleneamines include ethylenediamine (EDA), diethylenetriamine (DETA) and higher amines. EDA is used to produce TAED (tetraacetylethylenediamine) and EDTA (ethylenediamine tetraacetic acid), and in fungicides. DETA is mainly used as an epoxy curing agent and in the production of wet strength resins for paper. Higher amines are used to make additives for lubricating oils, engine fuels and asphalt.

Tank Cleaning: Cargoes consisting of mixtures with different vapor pressures should neither be cleaned by evaporation, nor prewashed hot. The evaporation of the light substances from a mixture could result in non-volatile residues, which are very difficult to remove.

The rate at which a product will vaporize when compared to the rate of vaporization of a known material (usually Butyl Acetate with rate designated as 1.0). Evaporation rate can be useful in evaluating the health and fire hazards of a material. Rates are classified as fast (greater than 3.0), medium (.8 to 3.0), and slow (less than .8). The evaporation rate of water is .3.
