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.

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.

The various processes of a plant are segmented into separate process blocks that are connected to one another using fluid conduits or electrical connections. Each process block is specialized to perform specific tasks in an assembly line manner to achieve an overall goal. For example, multiple distillation process blocks could be daisy-chained to create fuel from crude oil. Each process block is generally small enough to be mounted on a truck or a flatbed for easy transport, allowing for an assembly line of process blocks to be transported anywhere in the world with ease.

It is widely recognized by experts that the computer-based design of chemical processes depends strongly on the correlated thermodynamic and transport properties, and that the effect of the property uncertainties should be accounted for in the design. The most significant source of property uncertainties on process design comes from the correlations of mixture phase equilibrium. Many approaches to uncertainty analysis have been proposed, but uncertainty analysis is not a routine element of today's industrial practice, mainly because education and awareness are lacking, and the proposed methods are difficult to apply.In order to help rectify the situation, the author developed an intuitive and easy-to-apply phase-equilibrium (specifically, activity coefficient) perturbation method based upon treating the mixture, for the purpose of uncertainty perturbation, as a set of pseudobinaries described by the Margules equation. The approach was applied to two case studies - (1) a propylene-propane superfractionator for which small changes in correlated relative volatilities have a large effect on the design of the distillation column; and (2) a dehexanizer column that separates a mixture containing many close-boiling components - and demonstrated that the proposed methodology provides quantitative insight into the effect of property uncertainties, and helps to estimate the safety factors that should be imposed upon the design.In this paper the Margules perturbation method is applied to the "textbook" separation of an acetone-chloroform-benzene ternary mixture; this case study was proposed in 1996 by Westerberg and Wahnshafft, and was previously studied by Parodi and Campanella. The approach of Parodi and Campanella used different levels of data fitting to identify uncertainties, while the present methodology is to obtain the best fit of the data, and then apply uncertainties based upon estimated combined model uncertainties, which includes experimental uncertainties and any model inadequacies. The purpose of this paper is to further study whether the Margules approach to mixture uncertainty offers insight, and is a useful technique to perform uncertainty analysis. © 2015 Elsevier B.V.

A support rib for securing a rotor pole to a flange in a gearless drive is described. The support rib is undivided and passes through an opening of the flange. The support rib can be joined with the flange and/or the rotor pole using an adhesive. The rib preferably has at least one notch that engages an edge of the flange opening to establish mechanical connection between the rib and flange. An insert with two ends that slideably engages a rib edge and rotor pole channel can be used to couple the rib to the rotor pole.

Corrosion in a CO2 removal system is reduced or even entire avoided by use of a metal ion chelator unit that removes metal ions, and especially iron ions from an amine solvent to a level of equal or less than 1 mg/1 without substantially binding heat stable salts.
