Fluor Corporation is a multinational engineering and construction firm headquartered in Irving, Texas. It is a holding company that provides services through its subsidiaries in four areas: energy and chemicals, industrial and infrastructure, government and Fluor Global Services such as staffing and equipment rentals. It is the largest construction company in the Fortune 500 rankings and the 109th largest company overall.Fluor was founded in 1912 by John Simon Fluor as Fluor Construction Company. It grew quickly, predominantly by building oil refineries, pipelines and other facilities for the oil and gas industry, at first in California, and then in the Middle East and globally. In the late 1960s, it began diversifying into oil drilling, coal mining and other raw materials like lead. A global recession in the oil and gas industry and losses from its mining operation led to restructuring and layoffs in the 1980s. Fluor sold its oil operations and diversified its construction work into a broader range of services and industries.In the 1990s, Fluor introduced new services like equipment rentals and staffing. Nuclear waste cleanup projects and other environmental work became a significant portion of Fluor's revenues. The company also did projects related to the Manhattan Project, rebuilding after the Iraq War, recovering from Hurricane Katrina and building the Trans-Alaska Pipeline System. Wikipedia.

A system for reducing SO_(2 )emissions comprises a hydrogenation reactor, a tail gas cooler, a contact condenser, a hydrolysis reactor, and an absorber. The hydrogenation reactor is configured to receive a Claus tail gas and convert at least a portion of SO_(2 )in the Claus tail gas to H_(2)S to produce a hydrogenated Claus tail gas stream. The hydrolysis reactor is configured to convert at least a portion of COS to H_(2)S. The absorber comprises an amine-based solvent and is configured to absorb at least a portion of the H_(2)S and recycle the H_(2)S to the Claus plant.

Contemplated plants for flexible ethane recovery and rejection by allowing to switch the top reflux to the demethanizer from residue gas to the deethanizer overhead product and by controlling the flow ratio of feed gas to two different feed gas exchangers. Moreover, the pressure of the demethanizer is adjusted relative to the deethanizer pressure for control of the ethane recovery and rejection.


Advanced oxygen enrichment technologies for Claus plants are presented that provide an oxygen rich gas stream to the Claus burner of the thermal stage and one or more oxygen rich bypass gas streams to at least one of the catalytic stages to so increase the capacity of the plant while reducing the amount of recycle gases needed for flame temperature moderation.

A subsea wellbore protection (SWP) system. The SWP system includes a wellbore penetrating a subterranean formation beneath a sea floor and a SWP structure positioned below grade with respect to the sea floor. The SWP structure comprises a caisson that encloses a first wellbore equipment component. The first wellbore equipment component is in fluid communication with the wellbore.


Variable N2 content in feed gas ranging from 3 mol % to 50 mol % can be rejected from the process using a feed exchanger that is fluidly coupled with a cold separator and a single fractionation column to produce a nitrogen vent stream and streams that are suitable to be further processed for NGL recovery and LNG production.

A module for an engineering, procurement, and construction (EPC) project is described. The module comprises machinery disposed on a baseplate. The baseplate is coupled with a support structure via adjustable, self-leveling chocks. The chocks maintain a level baseplate surface regardless of whether or not the underside of the baseplate and the support structure are parallel. The chocks reduce and/or eliminate the transfer of the deflection forces from the support structure to the baseplate.

A system for analyzing a coking system comprises a coking system comprising a first coke drum and a second coke drum, and a user device communicatively coupled to a hardware implemented analysis engine. The coking system configured to collect and transmit coke drum data to the hardware implemented analysis engine. The hardware implemented analysis engine is configured to: receive an estimation of an altered life span of the first coke drum relative to a design life span of the first coke drum, analyze an effect of adding an additional coke drum to the coking system based on the altered life span, and provide a result item related to the analysis to the user device. The estimation of the altered life span is based on the coke drum data.

Hydrogen sulfide is selectively enriched from an acid gas (1) that comprises relatively large quantities of carbon dioxide using a configuration in which a portion of an isolated hydrogen sulfide stream is introduced into an absorber (51) operating as a carbon dioxide rejecter. The resulting concentrated hydrogen sulfide enriched solvent (4) is then further used (directly or indirectly) to absorb hydrogen sulfide from an acid feed gas.


Systems and methods for reducing the energy requirements for carbon dioxide capture are described. Heat from system processes, such as steam condensation and hot flue gas, is utilized to heat reflux liquid utilized in release of carbon dioxide from absorbent solvent.


Acid gas is removed from a high pressure feed gas that contains significant quantities of CO2 and H2S. In especially preferred configurations and methods, feed gas is contacted in an absorber with a lean and an ultra-lean solvent that are formed by flashing rich solvent and stripping a portion of the lean solvent, respectively. Most preferably, the flash vapors and the stripping overhead vapors are recycled to the feed gas/absorber, and the treated feed gas has a CO2 concentration of less than 2 mol % and a H2S concentration of less than 10 ppmv, and more typically less than 4 ppmv.
