The present invention generally relates to a process for making a metal oxide composition for use in removing contaminants from streams. A process of the present disclosure comprises contacting a metal salt with an aqueous solvent to form a metal salt mixture and reacting the metal salt mixture and a metal powder without the addition of heat. The present invention also relates to a process for making a coated metal oxide substrate.

Method for producing metal oxide compositions and coated substrates

The present invention generally relates to a process for making a metal oxide composition. The present invention also relates to a process for making a coated metal oxide substrate.

Method for producing dry metal oxide compositions and coated substrates

The present invention relates to a compressed metal oxide composition particle comprised of metal oxide and an organic binder, with the binder preferably being a water insoluble cellulose composition. The present invention also relates to a method for forming a compressed metal oxide composition particle, with the preferred method including compressing a metal oxide and binder mixture to form compressed metal oxide composition particles having a final particle size of between about 0.1 mm and about 200 mm.

Method for removing sulfur compounds from fluids using compressed metal oxide composition particles

In ridding fluids, including hydrocarbon fluids, both gaseous and liquid, of sulfur compounds including hydrogen sulfide, oxides of sulfur, and thiols, the present invention uses a small quantity of an activator, generally a noble metal oxide, preferably a copper species, along with a known oxide product, such as iron oxide or zinc oxide, to thoroughly remove sulfur contaminants in a short amount of time. The activator allows for the use of smaller reactor vessels and the production of hydrocarbon fluids substantially free of sulfur products.

Composition for scavenging sulfur compounds from fluids

In ridding fluids, including hydrocarbon fluids, both gaseous and liquid, of sulfur compounds including hydrogen sulfide, oxides of sulfur, and thiols, the present invention uses a small quantity of an activator, generally a noble metal oxide, preferably a copper species and/or a manganese species, along with a known oxide product, such as iron oxide, iron hydroxide, zinc oxide, zinc hydroxide, manganese oxide, manganese hydroxide, or combinations thereof, to thoroughly remove sulfur contaminants in a short amount of time. The activator allows for the use of smaller reactor vessels and the production of hydrocarbon fluids substantially free of sulfur products.

Composition for increasing the reactivity of sulfur scavenging oxides

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.

Compressed metal oxide product

A product, capable of treating contaminated fluids, preferably gases, is disclosed. The product contains a carrier, an activated metal oxide, an odor counteractant, a carrier for the odor counteractant, and an agent which limits diffusion of the odor counteractant. The product removes sulfur contaminants, such as hydrogen sulfide and mercaptans, while also reducing and/or neutralizing other common odor causing compounds in fluids, preferably gases. Methods of making and using the product are also disclosed.

Product for treating contaminated fluids and method of making and using the same

The present invention relates to a device for use in a manhole or similar structure, whereby the device is designed to filter contaminate gas typically found in such structure. More particularly, the device includes a canister member filled with filtration media, a skirt member designed to direct contaminate gases towards the canister, and a support member for holding the canister in place.

Device for use in filtering contaminated air

A process is provided for removing sulfur compounds, such as hydrogen sulfide, sulfur oxides and thiols, out of fluids, such as natural gas or natural gas liquids, by contacting the fluid with a physical mixture of iron oxide, zinc oxide or mixtures thereof and an activator, such as platinum oxide, gold oxide, silver oxide, copper oxide, copper metal, copper carbonate, copper alloy, cadmium oxide, nickel oxide, palladium oxide, lead oxide, mercury oxide, tin oxide and cobalt oxide, preferably copper oxide wherein the activator is present in an amount equal to 0.125% by wt. to 5% by wt. of the total physical mixture. The contacting is conducted at a temperature of 300&deg; C. or less.

Process for increasing the reactivity of sulfur compound scavenging agents

The present invention relates to an activated metal oxide and methods for removing sulfur compounds from fluids, whereby the activated metal oxide includes an amount of metal oxide and an amount of ethoxylated fatty amine, with the ethoxylated fatty amine increasing the rate of reactivity between the metal oxide and the sulfur compounds, which include hydrogen sulfide, carbonyl sulfide, mercaptans, and other organic sulfides. The ethoxylated tallow amines include ethoxylated tallow amine, ethoxylated cocoa amine, ethoxylated oleic amine, ethoxylated soya amine, ethoxylated palmatic amine, ethoxylated steric amine, and combinations thereof. The method involves activating the metal oxide, preferably iron oxide or zinc oxide, with an amount of ethoxylated fatty amine so that when fluids, such as water or liquid hydrocarbons, contact the metal oxide the sulfur compounds are removed.

Composition for removing sulfur compounds from fluids

The present invention relates to the use of metal oxide particles held on carrier particles and moistened with a hygroscopic moistening agent, preferably glycol, with the moistened metal oxide particles used in a system designed to remove sulfur from dehydrated and water under-saturated gas compounds.

Metal oxide product suitable for use in dehydrated gas

A method is provided for removing carbonyl sulfide out of a H.sub.2 O-containing fluid stream, such as petrochemical vent gas, air, carbon dioxide, nitrogen and hydrocarbons, by determining how much carbon monoxide is present in the fluid stream; adding carbon monoxide to the fluid stream to obtain a carbon monoxide to carbonyl sulfide volume ratio of at least 1:1 and to also convert the carbonyl sulfide into hydrogen sulfide and carbon dioxide, and passing the hydrogen sulfide containing fluid through a hydrogen sulfide removal system, so as to obtain a fluid substantially free from carbonyl sulfide and hydrogen sulfide.
