Exxon Mobil Corp., or ExxonMobil, is an American multinational oil and gas corporation headquartered in Irving, Texas, United States. It is a direct descendant of John D. Rockefeller's Standard Oil company, and was formed on November 30, 1999, by the merger of Exxon and Mobil . It is affiliated with Imperial Oil which operates in Canada.The world's 5th largest company by revenue, ExxonMobil is also the second largest publicly traded company by market capitalization. The company was ranked No. 6 globally in Forbes Global 2000 list in 2014. ExxonMobil's reserves were 25.2 billion BOE at the end of 2013 and the 2007 rates of production were expected to last more than 14 years. With 37 oil refineries in 21 countries constituting a combined daily refining capacity of 6.3 million barrels , ExxonMobil is the largest refiner in the world, a title that was also associated with Standard Oil since its incorporation in 1870.ExxonMobil is the largest of the world's supermajors with daily production of 3.921 million BOE. In 2008, this was approximately 3 percent of world production, which is less than several of the largest state-owned petroleum companies. When ranked by oil and gas reserves, it is 14th in the world—with less than 1 percent of the total.ExxonMobil has been subject to numerous criticisms, including the lack of speed during its cleanup efforts after the 1989 Exxon Valdez oil spill in Alaska, widely considered to be one of the world's worst oil spills in terms of damage to the environment. ExxonMobil has drawn criticism for funding organizations that are skeptical of the scientific opinion that global warming is caused by the burning of fossil fuels. Questions have been raised about the legality of the company’s foreign business practices. Critics note that ExxonMobil increasingly drills in terrains leased by dictatorships. The company has also been the target of accusations of improperly dealing with human rights issues, influence on American foreign policy, and its impact on the future of nations. Wikipedia.

The present application is directed to a method for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

This disclosure relates to a process for polymerization, and in particular to minimizing undesired polymerization reactions downstream of a polymerization reaction zone, for instance by use of a quenching agent that enables fast reaction rates with active polymerization catalyst in the polymerization effluent, so as to quench the catalyst quickly, thereby preventing uncontrolled polymerization reactions. A preferred quenching agent is methanol. Also provided are means for treating polymer recycle streams containing oxygenates, which may result from the use of such quench agents, particularly in polymerization processes including polyene (e.g., diene) monomers.


Method and system is described to exploration and development hydrocarbon resources. The method involves operations for exploring and developing hydrocarbons with one or more unmanned vehicles. The unmanned vehicles are used to obtain one or more samples that may be used to identify hydrocarbon systems, such as hydrocarbon seeps.


Methods are provided for modifying hydrogenation catalysts having silica supports (or other non-alumina supports) with additional alumina, and using such catalysts to achieve unexpectedly superior hydrogenation of feedstocks. The modified hydrogenation catalysts can have a relatively low cracking activity while providing an increased activity for hydrogenation.

This invention relates to a copolymer prepared using two or more non-coordinating anion activators comprising a first C2 to C12 alpha olefin (such as ethylene), a second C3 to C12 alpha olefin (such as propylene) different from the first alpha olefin, and diene (such as ethylidene norbornene and/or vinyl norbornene), where the polymer has: a) first alpha olefin (ethylene) content of 35 to 90 mol%; b) second alpha olefin (propylene) content of 9.8 to 64.8 mol%; c) diene content of 0.2 to 5 mol%; d) a branching index gave of 0.95 or more; e) a complex viscosity ratio (eta*(0.01rad/s)/eta*(100rad/s), at 125C) greater than 1.1 *Y0, where Y0 = Y1+{[(Y2-Y1)/(X2-X1)](X0-X1)}, where X0 is the wt% of a first non-coordinating anion activator, NCA1, used to prepare the copolymer (based upon weight of NCA1 and a second non-coordinating anion activator, NCA2, used to prepare the copolymer), X1 = 0, X2 =100, Y1 = complex viscosity ratio of polymer made with 100% NCA1 and 0% NCA2, Y2 is complex viscosity ratio of polymer made with 100% NCA2 and 0% NCA1, where NCA1 has an Mw lower than the Mw of NCA2; f) an Mw/Mn of 4.0 or less; g) a melting point of 30C or less; and h) a Composition Distribution Breadth Index of 50% or more.


A system and method is provided for generating an optimized ship schedule to deliver liquefied natural gas (LNG) from one or more LNG liquefaction terminals to one or more LNG regasification terminals using a fleet of ships. The method involves modeling the ship schedule via an LNG ship scheduling model and a LNG ship rescheduling model to provide optimized decisions for the LNG supply chain. The LNG supply chain includes the one or more LNG liquefaction terminals, the one or more LNG regasificatson terminals, and the fleet of ships.

The current disclosure relates to multiphase fluid separation via a multiphase separation system. The multiphase separation system is configured to feed a multiphase fluid into an inlet line (204) within the separation system. The multiphase fluid is configured to flow through a divide (206) and be split into separate lines (208, 210) of similar diameter. A control volume (214) is also connected at the end of the separate lines (208, 210), and the control volume (214) has a diameter greater than the separate lines (208, 210) of similar diameter. The control volume (214) includes outlet lines (216, 218), and is configured to adjust fluid flow rate at an outlet line. Also included in the current disclosure is a sand boot (212) connected to the separate lines (208, 210) that is oriented vertically with respect to the separate lines (208, 210), and is configured to collect and remove sand accumulated in the multiphase separation system.


Systems and methods are providing for integrating a cavitation unit to the backend separation system of a hydrotreater to improve conversion.


Methods are provided for producing Group II / III lubricant base oil products where at least a portion of the feedstock for forming the lubricant base oil product is a solvent extract fraction from a Group I lubricant production facility. This can increase the overall volume of feedstock available for production of Group II / III lubricant base oils by using a lower value stream (Group I solvent extract) as a portion of the feedstock. The solvent extract fraction can be added to a full range lubricant feedstock or to a portion of a lubricant feedstock, such as adding an extract fraction to a higher viscosity portion (such as a heavy neutral portion) of a feedstock for lubricant production, while a lower viscosity portion (such as a light neutral portion) is processed without addition of an extract fraction.

Methods and systems for providing real-time monitoring of a metal surface are provided herein. The system includes a fiber-optic cable disposed alongside a length of a wall that includes the metal surface. A laser source is attached to the fiber-optic cable to transmit light through the fiber-optic cable. An acoustic source is configured to generate acoustic signals in the metal surface, wherein the acoustic signals interact with the fiber-optic cable and influence characteristics of the light. A receiver is attached to the fiber-optic cable to detect the light. The system also includes a signal processing unit configured to determine a location of a change in the metal surface based on changes in the characteristics of the light.
