Abstract: The present application is directed to a method and system 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.

Abstract: The separation of a target gas selected from a high pressure gas mixture containing said target gas as well as a product gas using a swing adsorption process unit. A turboexpander is used upstream of the swing adsorber to reduce the pressure of the high pressure gas mixture. A compressor is optionally used downstream of the swing adsorber to increase the pressure of the target gas-containing stream for injecting into a subterranean formation.

Abstract: The present invention relates the separation of a target gas from a mixture of gases through the use of engineered structured adsorbent contactors in pressure swing adsorption and thermal swing adsorption processes. Preferably, the contactors contain engineered and substantially parallel flow channels wherein 20 volume percent or less of the open pore volume of the contactor, excluding the flow channels, is in the mesopore and macropore range.

Abstract: A class of new oxide structures containing octahedral molybdenum and tetrahedral phosphorous has been generated using hydothermal techniques. These materials are produced by the reaction of a molybdenum oxide source with phosphate and any one, or combination of organic cation/alkali-metal cation/organic amine as a templating/mineralizing agent. A reducing agent is necessary to convert the Mo(VI) to a lower valent form and can be either added to the reaction mixture or is provided in the form of one the reactants.
