The invention relates to processes for producing anode grade coke from whole crude oil. The invention is accomplished by first deasphalting a feedstock, followed by processing resulting DAO and asphalt fractions. The DAO fraction is hydrotreated or hydrocracked, resulting in removal of sulfur and hydrocarbons, which boil at temperatures over 370 C., and gasifying the asphalt portion in one embodiment. This embodiment includes subjecting hydrotreated and/or unconverted DAO fractions to delayed coking. In an alternate embodiment, rather than gasifying the asphalt portion, it is subjected to delayed coking in a separate reaction chamber. Any coke produced via delayed coking can be gasified.


This document relates to compositions including a crosslinkable polymer including a pendant epoxide repeat unit and an amine crosslinker, and methods of treating a subterranean formation by providing the composition to the formation. The pendant epoxide repeat unit has the structure Each R^(1 )is independently a (C_(1)-C_(10)) alkylene or (C_(1)-C_(10)) alkylene ether, each alkylene ether independently having a ratio of carbon atoms to oxygen atoms of 1:1 to 4:1.


Systems and methods are described for liquid removal to increase the accuracy of gas flow meters, such as venturi meters. Systems and methods include a liquid knockout drum, an impingement plate, a drum separator, and a check valve.

A method includes receiving a water stream from a hydrocarbon production facility, the water stream having a first concentration of a kinetic hydrate inhibitor (KHI); flowing the water stream through a heat exchanger to heat the water stream to a target temperature; mixing the heated water stream with a treatment chemical to form a two-phase mixture, the treatment chemical having an affinity for the KHI; flowing the two-phase mixture into a separator; and physically separating the two-phase mixture into a first phase and a second phase, the first phase including water and having a second concentration of the KHI less than the first concentration, and the second phase including the KHI and the treatment chemical, the density of the second phase being less than the density of the first phase.


Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula Cu_(x)Zn_(1-x)Al_(2)O_(4) in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SO_(x) and low sulfur hydrocarbons. The by-product SO_(x) is subsequently removed, producing a stream containing a reduced level of organosulfur compounds.

An oil field process control system including a field versatile control gateway component that interfaces with a plurality of field devices using a broad range of hardwired and wireless protocols, offering in-the-field monitoring and control of each of the field devices and communicates with a remote central control room, exchanging data between the control room and the field using a multiplexed protocol that offers high data speeds and bandwidth, enabling a significant reduction of the amount of wiring, and conduits and other infrastructure expenses that would otherwise be incurred for such a highly reliable communications system.


An improved system and method for processing feedstocks in an ebullated-bed hydroprocessing reactor is provided in which hydrogen gas is dissolved in the fresh and recycled liquid feedstock by mixing and/or diffusion of an excess of hydrogen, followed by flashing of the undissolved hydrogen upstream of the reactor inlet, introduction of the feed containing dissolved hydrogen into the ebullated-bed hydroprocessing reactor whereby the dissolved hydrogen eliminates or minimizes the prior art problems of gas hold-up and reduced operational efficiency of the recycle pump due to the presence of excess gas in the recycle stream when hydrogen gas was introduced as a separate phase into the reactor.

Changes in engine technology, driven by the need to increase the efficiency of the SI engine and reduce NOx and soot from diesel engines, and in transport energy demand will have a profound effect on the properties, specifications and production of future fuels. The expected increase in global demand for transport energy is significantly skewed towards heavier fuels like jet fuel and diesel compared to gasoline. Abnormal combustion such as knock and preignition will become more likely as spark-ignition (SI) engines develop to become more efficient and fuel antiknock quality will become more important. In current and future SI engines, for a given RON (research octane number), a fuel of lower MON (motor octane number) has better antiknock quality. Current fuel specifications in several parts of the world assume that MON contributes to antiknock quality and will need to be revised as the mismatch with engine requirements widens. Diesel engines need to maintain efficiency while reducing emissions of soot and NOx. Soot and NOx can be controlled more easily if such engines are run on fuels of extremely low cetane. In the long term compression ignition engines could run on fuels which require less processing in the refinery compared to today's fuels. Such an engine/fuel system could be significantly cheaper and also help mitigate the expected demand imbalance in favour of heavier fuels. The review concludes with a list of issues for combustion science that are relevant to this fuel and engine development. © 2014 The Combustion Institute.
