Petroleum or crude oil is a complex mixture of hydrocarbons and other chemicals. The composition varies widely depending on where and how the petroleum was formed. In fact, chemical analysis can be used to fingerprint the source of petroleum.

In this study, the effects of particle size distribution PSD , chemical composition and pore structure of petroleum coke on the slurryability of petroleum coke water slurry PCWS were investigated. Four petroleum cokes were studied, and they showed completely different slurryability. The solid concentration at fixed viscosity i. The apparent viscosity of the four PCWSs all increased with an increase of the solid concentration. The results showed that the PSD, inherent moisture content, specific surface area and pore volume of petroleum coke were key factors to affect the slurryability. The slurryability was enhanced with increasing PSD range and particle packing fraction, and with decreasing inherent moisture content, specific surface area and pore volume.

Crude oils are naturally occurring liquid phase of petroleum, composed principally of hydrocarbon compounds and are extracted from the earth in the liquid state. The hydrocarbon compounds in crude oils include paraffins ranging from pentane to pentadecane C5 — C15 , alkylparaffins, naphthenes, alkylbenzenes and nuclear aromatics. Other associated matters are natural gases, hydrocarbon waxes, and salt water. View PDF.

Tuncan, A. The effects of municipal sewage sludge and crude oil on physical and mechanical properties of laboratory prepared marine clays were investigated. Contaminants appeared to influence the development of clay microstructure and thus some of the physical and mechanical properties of sedimented marine clay. A mixture of illite, Ca-montmorlllonite. Among the physical and mechanical properties measured or observed are physico-chemical properties, index properties, microstructure, shear strength, stiffness, permeability and compressibility. The influence of crude oil and sludge on these physical and mechanical properties and the microstructure was evaluated based on criteria such as flocculation. The impact of progressive pollution of the world oceans has become an important problem for the researchers to solve.

A summary treatment of crude oil follows. For full treatment, see petroleum , petroleum production , and petroleum refining. Crude oil is a mixture of comparatively volatile liquid hydrocarbons compounds composed mainly of hydrogen and carbon , though it also contains some nitrogen , sulfur , and oxygen.

Physical and Chemical Properties of Crude Oils and Their Geologic Significances

Evaluation and characterization of physical properties, chemical composition and behavior of petroleum products is crucial to predict environmental behaviour in the event of spills. This information can inform the prediction and modeling of fate and behavior of the oils in different environmental conditions. Good models of oil and petroleum products fate and behaviours are essential for spill preparedness planning, environmental effects and impact assessments, and choosing response and countermeasure strategies for the cleaning of spills. This database is a collection of physical properties, chemical compositions and simulated environmental behaviors of unrefined crude oils and refined petroleum products including diesels, biodiesels, crude oils, intermediate and fuel oils, bitumen and diluted bitumen. When applicable, the petroleum products were weathered by simulated evaporation weathering method in the ESTS lab to produce samples at different weathering states light, moderately, heavily and very heavily weathered , followed by analyses based on American standard test methods when available or in-house methods.

Crude oil derives, by way of geological processing, from organic material initially buried in sediments at the bottom of ancient lakes and oceans. Crude oil formed at depth in a sedimentary basin migrates upward because of lower density. If the oil approaches the surface, it cools and comes in contact with groundwater.

Командир подводной лодки мог получить последние спутниковые фотографии российских портов, но не имел доступа к планам действий подразделений по борьбе с распространением наркотиков в Южной Америке. Эксперты ЦРУ могли ознакомиться со всеми данными об известных убийцах, но не с кодами запуска ракет с ядерным оружием, которые оставались доступны лишь для президента. Сотрудники лаборатории систем безопасности, разумеется, не имели доступа к информации, содержащейся в этой базе данных, но они несли ответственность за ее безопасность. Как и все другие крупные базы данных - от страховых компаний до университетов, - хранилище АНБ постоянно подвергалось атакам компьютерных хакеров, пытающих проникнуть в эту святая святых. Но система безопасности АНБ была лучшей в мире. Никому даже близко не удалось подойти к базе АНБ, и у агентства не было оснований полагать, что это когда-нибудь случится в будущем.

 Не смей прикасаться! - Стратмор рванулся к терминалу и отдернул ее руку. Обескураженная, Сьюзан подалась. Она смотрела на коммандера и второй раз за этот день не могла его узнать. Вдруг она ощутила страшное одиночество.

Ему сразу же стало ясно, что высокое положение в тридцать восемь лет в АНБ нельзя получить за красивые глаза: Сьюзан Флетчер оказалась одной из умнейших женщин, каких ему только доводилось встречать. Обсуждая шифры и ключи к ним, он поймал себя на мысли, что изо всех сил пытается соответствовать ее уровню, - для него это ощущение было новым и оттого волнующим. Час спустя, когда Беккер уже окончательно опоздал на свой матч, а Сьюзан откровенно проигнорировала трехстраничное послание на интеркоме, оба вдруг расхохотались.

Он кивнул: - Чтобы предупредить. - Предупредить. Он же вас ненавидит. - Он позвонил и предупредил, что заканчивает работу над алгоритмом, создающим абсолютно стойкие шифры.

Я рассказал о нем полицейскому.

Crude oil can be described as paraffin base, naphthene base or mixed base, depending on the most abundant group of hydrocarbons contained. Crude oils also.
