    Abstract: The present invention relates to a bound metal oxide particle comprised of metal oxide and a binder, with the binder preferably being a starch solution. The present invention also relates to a method for forming a bound metal oxide particle, with the preferred method including extruding and pelletizing a metal oxide and binder composition to form pelletized metal oxide particles.

    Abstract: Adding sodium sulfite in the slurry of the iron oxide slurry process for scavenging hydrogen sulfide described in U.S. Pat. No. 4,246,244, eliminates excessive foaming on start-up, stabilizes the suspension of the oxide particles in the slurry, lessens clogging of reacted particles, which otherwise interferes with cleaning out the reactor vessel, and so materially buffers the slurry as to minimize corrosion of the reactor vessel and piping. Further, adding small amounts of oxygen to the gas stream, which would be expected to cause corrosion, does not do so; instead it prolongs the usefulness of the reactant oxide particles and affords increased acid-stability to the reaction products.

    Abstract: The present invention provides a method for separately removing mercaptans and hydrogen sulfide from a hydrocarbon gas stream by passing the gas through a bed which includes iron oxide which catalyzes the formation of disulfides and trisulfides from mercaptans and also reacts with at least part of the hydrogen sulfide to form acid-stable solids; causing the di- and trisulfides to exit the bed in the gas phase; and removing and recovering the di- and trisulfides by adsorption or condensation. Any remaining hydrogen sulfide may be scavenged from the gas stream by passage through a bed containing iron oxide similar to that used first above. If the gas stream contains substantial amounts of hydrocarbon aerosols, they should be filtered out in advance of the bed.

    Abstract: A system of apparatus is especially adapted to react gaseous contaminates of natural gas streams with a slurry of reactant particles and incorporates a contactor tower with a bottom gas inlet having a screen at its dynamic liquid level to confine downwardly a fill of packer-spacer material. Gas entering through the bottom inlet of the tower is divided by the packer-spacer material in tortuous flow paths maintained by the confining screen.In advance of the contactor tower, after an inlet scrubber, is a heater which elevates the temperature of the gas before it enters the contactor tower. This avoids formation of clogging hydrates and liquefication of the gas. Using an outlet scrubber assures against entrance of droplets of any liquid into the pipeline.
