People who do not follow standard safety practices are killed or injured every year while closing or removing tanks. For a safe closure, you need qualified professionals who will use standard safety practices.

- The Oil and Gas Industry in Energy Transitions
The oil and gas industry is facing increasing demands to clarify the implications of energy transitions for their operations and business models, and to explain the contributions that they can make to reducing greenhouse gas emissions and to achieving the goals of the Paris Agreement. The increasing social and environmental pressures on many oil and gas companies raise complex questions about the role of these fuels in a changing energy economy, and the position of these companies in the societies in which they operate. The oil and gas industry is facing increasing demands to clarify the implications of energy transitions for their operations and business models, and to explain the contributions that they can make to reducing greenhouse gas GHG emissions and to achieving the goals of the Paris Agreement. This report does not aim to provide definitive answers, not least because of the wide diversity of oil and gas companies and company strategies around the world. It does aim to map out the risks facing different parts of the industry, as well as the range of options and responses. Three considerations provide the boundaries for this analysis. First, the prospect of rising demand for the services that energy provides due to a growing global population — some of whom remain without access to modern energy — and an expanding global economy.
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. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified. Regardless of variations, however, almost all crude oil ranges from 82 to 87 percent carbon by weight and 12 to 15 percent hydrogen by weight. Crude oils are customarily characterized by the type of hydrocarbon compound that is most prevalent in them: paraffins , naphthenes , and aromatics. Paraffins are the most common hydrocarbons in crude oil; certain liquid paraffins are the major constituents of gasoline petrol and are therefore highly valued.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. The interpretive dilemma becomes further aggra- vated by chemical and microbial alterations that occur after intro- duction of a particular set of hydrocarbon compounds to the mar ine environment, a set originally attributable to a source but subsequently modif led. This section bight ights the main compositional character- istics of the hydrocarbon sources to the mar ine environment and distinguishes features of each source.
The future is now: How oil and gas companies can decarbonize
Natural gas and crude oil are mixtures of different hydrocarbons. Hydrocarbons are molecules of carbon and hydrogen in various combinations. Hydrocarbon gas liquids HGLs are hydrocarbons that occur as gases at atmospheric pressure and as liquids under higher pressures.
Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide CO2 when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [ 1 ].

In petrochemistry , petroleum geology and organic chemistry , cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon -carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkenes. Simply put, hydrocarbon cracking is the process of breaking a long chain of hydrocarbons into short ones.

Тебе больше нечем заняться? - Сьюзан метнула на него недовольный взгляд. - Хочешь от меня избавиться? - надулся Хейл. - Если честно - да, - Не надо так, Сью, Ты меня оскорбляешь. Глаза Сьюзан сузились. Она терпеть не могла, когда он называл ее Сью.

Хорошенькая картинка. Беккер застонал и начал выбираться из расписанного краской из баллончиков зала. Он оказался в узком, увешанном зеркалами туннеле, который вел на открытую террасу, уставленную столами и стульями.
