Chemistry and Technology of Fuels and Oils, 1968 1. The curde oils from the Tengutino, Severo-Kamyshan, and Krasno-Kamyshan fields (N-APT) and that from the Kaspiisk field (baios) in the Kalmykian Autonomic Socialistic Soviet Republic are light, and contain a large amount of paraffins, but the sulfur content is low.

Various crude oil classifications have been proposed by geochemists and petroleum refiners. The purpose of these is very different, and also the physical or chemical parameters which have been used in the classifications. Petroleum refiners are mostly interested in the amount of the successive distillation fractions (e.g., gasoline, naphtha, kerosene ...

Petroleum originates from the bitumen of source rocks. Migration, however, and especially primary migration, is the cause of considerable changes in composition when bitumen is compared to petroleum. On the one hand, only a small amount of the total dispersed bitumen is mobilized and transferred into carrier or reservoir rocks, and an even smaller ...

Telemetering in the crude oil and crude oil products pipeline industry [PDF]
Electrical Engineering, 1961 From modest attempts to transmit data over short distances, telemetering systems in the pipeline industry have been developed which can transmit practically any variable to any desired point. Although present systems are highly sophisticated, many problems remain to be solved. A review of pipeline systems from early beginnings should help clarify these

Photooxidation is a potentially significant process in the degradation of crude oil spilled at sea. Moreover, a fundamental understanding of the effect of photochemical degradation on crude oil is a prerequisite for providing an accurate description of the recent history and potential fate of oil spilled in a marine environment.

Demulsification of the Emulsified Crude Oil and Defoaming of the Foaming Crude Oil
2018The demulsification of emulsified crude oil and defoaming of the foaming crude oil are discussed in this chapter. There are mainly two types of emulsified crude oil, water-in-oil (W/O) emulsified crude oil and oil-in-water (O/W) emulsified crude oil.

Numerous studies of the water-soluble fraction (WSF) from crude oil have concluded that polycyclic aromatic hydrocarbons (PAHs) are the primary causative agents for early life stage (ELS) fish toxicity.

The treatment of emulsified crude oils has been a problem for years in thepetroleum industry. Until comparatively recently various methods of settlingwith and without chemicals have been used with indifferent success. Since wellshave been acidized, emulsified crudes have been produced, which addconsiderably to the need for improved methods of treatment.

Global carbon intensity of crude oil production
Science, 2018New data enable targeted policy to lessen GHG emissions Producing, transporting, and refining crude oil into fuels such as gasoline and diesel accounts for ∼15 to 40% of the “well-to-wheels” life-cycle greenhouse gas (GHG) emissions of transport fuels (1)
