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.

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.

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.

Both a system and method for cleaning a low pressure separation vessel of a high pressure polyethylene polymerization plant are provided. The system includes a polytetrafluoroethylene lining that covers the interior surfaces of the vessel, and a cover mounting assembly including an annular clamp for detachably mounting a cover over the vessel. The mounting assembly includes a clamp actuator for quickly securing and releasing the cover with respect to a top rim of the vessel. The vessel is drained of liquid polyethylene and allowed to cool to ambient temperature, thus creating a frozen skin of polyethylene around the interior surfaces of the vessel. The clamp actuator releases the cover. The polyethylene skin is peeled off the interior sides the vessel and gathered up at the top to form a neck, thus peeling the polyethylene skin away from the polytetrafluoroethylene lining along with any degraded polymers or other impurities that have accumulated on the interior surfaces of the vessel.

Systems and methods for monitoring a condition of a tubular (30) configured to convey a fluid such as for use in producing hydrocarbons in relationship with a hydrocarbon system (14) related wellbore operation. The methods include transmitting a data signal (71) along the tubular (30) with a communication network (70). The methods may include initiating a tubular operation responsive to the data signal (71) indicating that the condition of the tubular (30) is outside a predetermined condition range. The methods may include transmitting the data signal (71) by propagating the data signal (71) along the tubular (30) via a plurality of node-to-node communications between communication nodes (72) of the communication network (70) and monitoring a signal propagation property of the plurality of node-to-node communications that is indicative of the condition of the tubular (30). The methods may include detecting the condition of the tubular (30) and generating a condition indication signal.

A method and system are provided for exploration, production and development of hydrocarbons. The method involves analyzing a sample for a geochemical signature, which includes a multiply substituted isotopologue signature and/or a position specific isotope signature. Then, historical temperatures are determined based on the signature. The historical temperature is used to define seal timing, trap timing, migration efficiency and/or charge efficiency, which is used to develop or refine an exploration, development, or production strategy.
