The term separator in oilfield terminology designates a pressure vessel used for separating well fluids produced from oil and gas wells into gaseous and liquid components. A separator for petroleum production is a large vessel designed to separate production fluids into their constituent components of oil , gas and water. A separating vessel may be referred to in the following ways: Oil and gas separator , Separator , Stage separator , Trap , Knockout vessel Knockout drum, knockout trap, water knockout, or liquid knockout , Flash chamber flash vessel or flash trap , Expansion separator or expansion vessel , Scrubber gas scrubber , Filter gas filter. These separating vessels are normally used on a producing lease or platform near the wellhead, manifold, or tank battery to separate fluids produced from oil and gas wells into oil and gas or liquid and gas. An oil and gas separator generally includes the following essential components and features:. Adequate vessel diameter and height or length to allow most of the liquid to separate from the gas so that the mist extractor will not be flooded. A means of controlling an oil level in the separator, which usually includes a liquid-level controller and a diaphragm motor valve on the oil outlet.
Powers, M. This paper concurs with this document as to vertical separator gas capacities, but differs in regard to gas capacities of horizontal vessels. Capacities calculated with this formula are compared graphically to those calculated by the standard procedure. Oil capacities are commonly based on theoretical residence times of 1to 4 minutes, depending on API gravity. A theoretical basis for oil capacity is herein developed that demonstrates that vessel proportions and orientation have significant influence on the value of residence time. An example is presented of horizontal and vertical separators having identical dimensions and equal liquid collection section volumes, in which it is shown that the oil capacity of the horizontal vessel is several times that of the vertical. Formulas for optimum vessel proportions are developed for cases in which both oil and gas capacities govern sizing.
The selection of Division 1 or Division 2 shall be based on both design and economic considerations. The use of the Code shall be limited to the following pressure such as:. If any of the following conditions apply, the vessels should be constructed in accordance with Division 2, unless otherwise specified by the Company. If either of the following conditions applies, the vessels shall be constructed in accordance with Division 2, unless otherwise approved by the Company. In general, the sizing of the separator will be carried out by the Process Engineer based on the target volume to be achieved, flow rate, density, operating temperature and pressure, and the need to precipitate droplets from gas, oil and water. Size parameters also include process considerations such as fluid velocity, fluid hold, and storage capacity.

This because horizontal separators separate based on the distance covered so that the separator base and length is longer than the height while vertical.
Oil and gas separators
Oil and gas production installations have to meet their quotas 24 hours a day. Whatever the conditions or location — the overriding priority has been unchanged for years: The machines have to run. Centrifuges from GEA provide reliability in every respect. For many decades, they have had a fixed place in the oil field industry and are known for the reliability and precision with which they do their job. Separating oil and water phases, purifying emulsions, removing cat fines: the requirements and procedures for processing crude oil, slop oil and other solid-liquid mixtures are fundamentally different.
SummaryThis chapter is a discussion of the design, use, functions, capacities, classifications, performance, operation, and maintenance of oil and gas separators. Quality of effluent fluids is approximated. Equations for calculating the sizes and capacities of separators and capacity curves and tables for sizing oil and gas separators are provided. These capacity curves and tables can be used to estimate capacities of separators as well as to determine the size of separator required to handle given volumes of fluids. Sample calculations for sizing separators are included.

Даю вам последний шанс, приятель. Где ваш пистолет. Мысли Стратмора судорожно метались в поисках решения. Всегда есть какой-то выход. Наконец он заговорил - спокойно, тихо и даже печально: - Нет, Грег, извини. Я не могу тебя отпустить. Хейл даже замер от неожиданности.
Вдалеке, метрах в пятистах, на фоне ночного неба возникли силуэты самолетных ангаров. Он подумал, успеет ли такси догнать его на таком расстоянии, и вспомнил, что Сьюзан решала такие задачки в две секунды. Внезапно он почувствовал страх, которого никогда не испытывал. Беккер наклонил голову и открыл дроссель до конца.
Техники и все прочие беспомощно смотрели на ВР. Джабба повернулся к монитору и вскинул руки. - Почему среди нас нет ни одного ядерного физика. Сьюзан, глядя на мультимедийный клип, понимала, что все кончено. Она следила за смертью Танкадо - в который уже .
