Refining
| Англо-русский глоссарий по металлургии |
A series of processes for converting crude oil and its fractions to finished petroleum products. following distillation, a petroleum fraction may undergo one or more additional steps to purify or modify it. these refining steps include; thermal cracking, catalytic cracking, polymerization, alkylation, reforming, hydrocracking, hydroforming, hydrogenation, hydrogen treating, hydrofining, solvent extraction, dewaxing, deoiling, acid treating, clay filtration, and deasphalting. refined lubricating oils may be blended with other lube stocks, and additives may be incorporated, to impart special properties.

Очистка, русский
- Фильтра обратной промывкой
- Отрасль обрабатывающей металлургии, связанная с извлечением металлов из руд и их очисткой от примесей.
- (1) влажный или сухой процесс механической очистки. (2) влажная или сухая чистовая обработка, при которой используется мелкий абразив и низкое давление. производится вручную или с помощью суконных полировальных кругов с целью получения сатинированной поверхности.
- Уз очищает металлы от полировочных паст, прокат от окалины, драгоценные камни от полировочных мест. очистка печатных форм, стирка тканей, мойка ампул.очистка трубопроводов сложной формы. кроме очистки, ультразвук способен производить удаление мелких заусенец, полировку
Рафинирование, русский
- Очистка от посторонних примесей какого-либо технического продукта.
- (нем . raffinieren, от франц. raffiner - очищать), окончательная очистка продукта от примесей в металлургической, химической, пищевой и других отраслях промышленности.
- Очистка чернового металла от примесей; рафиниро-вание благородных металлов называется аффинаж.

Преобразование; конвертирование
Distillation, английский
- Перегонка
- A water purification process in which water is converted to a vapor by boiling it, and then reconverted to purified water by cooling the vapor. disc tumbler lock 316 the process of distillation distribution box
- The action of distilling a liquid
- One of the oldest methods of separating oils from flowers and still widely used. it is a heat-dependent process for separation and purification of a liquid mixture based on differences in vapor pressure of components of the mixture. in each case, the flowers or other sources of oil are changed into a still and heat is applied to separate the oil. one type involves direct contact between the plant material and boiling water. in another type, the heat source is steam that is blown through the flowers. the process involves vaporization of the more volatile component(s) and then condensation of the vapor back to a liquid. the water and oil are collected and as they separate, the oil is removed from the top.

Polymerization, английский
- The chemical combination of similar-type molecules to form larger molecules.
- A chemical reaction in which the molecules
- A chemical reaction in which the molecular weight of the molecules formed is a multiple of that of the original substances. polymer-modified stucco a stucco containing a small amount of acrylic resin to increase its workability.
- A chemical reaction wherein small molecules combine to form much larger molecules. (also see addition polymerization and condensation polymerization.)
- The chemical reaction in which a monomer combines with itself to form a long-chained molecule called a polymer.
- The chemical combination and recombination of the same unsaturated hydrocarbon with itself to form an extensive chain; the chemical process of combining similar molecules to form larger molecules.
Alkylation, английский
The introduction of an alkyl radical into an organic molecule.
Hydrocracking, английский
Hydrogenation, английский
- In refining, the chemical addition of hydrogen to a hydrocarbon in the presence of a catalyst; a severe form of hydrogen treating. hydrogenation may be either destructive or non-destructive. in the former case, hydrocarbon chains are ruptured (cracked) and hydrogen is added where the breaks have occurred. in the latter, hydrogen is added to a molecule that is unsaturated with respect ot hydrogen. in either case, the resulting products are highly stable. temperatures and pressures in the hydrogenation process are usually greater than in hydrofining.
- Гидрирование, гидрогенизация. химическое присоединение водорода к другим веществам, обычно под действием высокой температуры и давления в присутствии катализатора. широко применяется в нефтяной промышленности.
- The process of passing hydrogen into an unsaturated chemical in the presence of a catalyst to convert the material to a more saturated state (i.e., containing more combined hydrogen.)
Extraction, английский
- Extraction is the process of removing essential oils from plant material using solvents, which are then evaporated, leaving just the oil.
- 1. the removal of part of the body, especially a tooth 2. in obstetrics, delivery, usually a breech presentation, which needs medical assistance
- Извлечение
- Выделение (сигнала); извлечение; добывание; экстрагирование
- A process for obtaining natural oils by means of tanks and solvents and is used with certain flowers and plants where the heat of steam distillation might damage or destroy the odorous substances or in such cases where the yield of oils is rather small. in one process, the tank is stationary and the solvent flows over the flowers or other natural matter. the other involves the use of a revolving unit inside of which the flowers move through the solvent. after removal of the solvent, alcohol is agitated through the remaining mixture of waxes and oils and the former is removed by chilling and filtering. the alcohol and oil mixture is then brought to the boiling point, the alcohol filtered off, and the concentrate allowed to remain for recovery. the concrete, as previously defined, is the pure essence in solid form from which an absolute is derived.
- Removal of one substance from another, often accomplished by a solvent.
- Removal of one substance from another, often accomplished by means of a solvent.
- The process of taking out useable ore from waste materials

Properties, английский
- A dockable window that displays the properties that are set on the selected object. in most cases, the property values can be edited in the window.
- A ui element that users can click to display information about a selected object.
