Abstract: Oxidative dehydrogenation catalysts comprising MoVNbTeO having improved consistency of composition and a 25% conversion of ethylene at less than 420° C. and a selectivity to ethylene above 95% are prepared by treating the catalyst precursor with H2O2 in an amount equivalent to 0.30-2.8 mL H2O2 of a 30% solution per gram of catalyst precursor prior to calcining.

Abstract: The oligomerization of ethylene using a chromium (Cr) catalyst having a phosphorus-nitrogen-phosphorus (P—N—P) ligand is known. Reactor fouling with by-product polyethylene can be severe at operating temperatures of greater than 60° C. However, the activation of such catalysts in a continuous flow reactor at low temperatures can be difficult and activity can be low. We have now discovered that highly active Cr/P—N—P catalysts may be prepared and activated in-situ (i.e. directly in the polymerization reactor) at low temperatures (from about 30 to about 45° C.) by combining the Cr; the P—N—P ligand and an aluminoxane in the process solvent in the presence of hydrogen. The use of hydrogen allows very high productivity (greater than 1×106 grams of ethylene conversion per gram of Cr) at low temperature. We have also observed reactor fouling rates as low as 2 to 10 parts per million of polyethylene per hour (based on total ethylene conversion) using this process.

Abstract: Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins, but has not been implemented commercially partially due to the unstable nature of hydrocarbon/oxygen mixtures, and partially due to the cost involved in the construction of new facilities. An oxidative dehydrogenation chemical complex designed to reduce costs by including integration of an oxygen separation module that also addresses safety concerns and reduces emission of greenhouse gases is described.

Abstract: A zone controller system that includes global communication of inputs, outputs and controller states from all zone controllers allowing each zone controller to operate based on inputs, outputs and controller states from all other zones. The zone controller system may also include direct one-to-one communication connections that allow additional communications. The system may include a user interface to configure operation of the zone controllers utilizing programmable logic equations that may use as variables the inputs, outputs and controller states of any zone controller. The user interface may be implemented in an off board configuration tool that is run on a computer connected to the global network. The system may also utilize one-to-one communications connections to provide self-repair and auto-configuration features. Each zone controller may store its ID(s) and configuration parameters on two other zone controllers, where they can be recovered for self-repair and auto-configuration.

Abstract: In some embodiments provided herein is a self-supported phosphinimine single site catalyst having a molar ratio of Al from the activator (MAO) to the active metal in the catalyst from 5:1 to 30:1. The catalyst is prepared by precipitating an emulsion of the activated catalyst from a perfluoroalkane continuous phase resulting in spherical catalyst particles having a diameter typically from 5 to 200 ?m.

Abstract: A tip burner for a flare comprises a diffuser (7) which is sealingly connected downstream to a shroud (9) comprising a tightly packed bed of granular material (13). The stream of fuel and oxidizer flows to a diffuser where is mixed and tangentially swirled by a swirler (8) located either in the diffuser or in a closed proximity to the diffuser inlet. The mixture flows next to the shroud where the granular material provides a tortious flow path for the stream, restructuring it aerodynamically and reducing its velocity, preferably to sub sonic level. A combustible mixture exits the shroud as multiple of jet, at low velocity and low turbulence. The mixture is ignited by a pilot burner installed above but in close proximity of the shroud, resulting in a stable flame which generates a low noise level.

Abstract: A method for preventing or removing water soluble fouling located downstream of an oxidative dehydrogenation (ODH) reactor is described. The method employs the introduction of water upstream of fouling locations, either continuously or intermittently, which acts to solubilize and carry away fouling material. The method has the advantage of being applicable for use while an ODH process is ongoing, circumventing the need for a costly shutdown.
