Methods and apparatus relate to measuring corrosion rate. Flowing corrosive fluid contacts a metal coupon or object and results in an effluent stream. The effluent stream contains metal from the object due to reaction of constituents in the fluid with the metal. Analysis of the effluent stream measures concentration of the metal therein. Since the concentration of the metal in the effluent stream is indicative of mass loss from the object, calculations provide the corrosion rate utilizing weight of the metal that is eluted, surface area of the object and exposure time of the object with the corrosive fluid.

Corrosion rate monitoring

Methods and apparatus relate to processing of petroleum with a bed having a sorbent based diluent that the petroleum contacts upon passing through the bed. Magnetic properties of the sorbent and any other material, such as zeolite, used in the bed enable separation of such bed constituents based on a sulfided form of the sorbent being magnetic in contrast to a non-sulfided form of the sorbent being non-magnetic. Dividing the bed constituents into first and second portions by magnetic separation facilitates in selective replacing and/or regenerating the first portion independent of the second portion.

Magnetic removal of material from a mixture based on sulfided diluent in the mixture

In a desulfurization process for the removal of organosulfur compounds from a hydrocarbon fluid stream such as cracked-gasoline or diesel fuel wherein a bifunctional sorbent system is employed, surface treatment of the bifunctional sorbent during the use of same for desulfurization results in an extension of the useful life of the bifunctional sorbent prior to the regeneration and reactivation of same for further use in the desulfurization of the hydrocarbon fluid stream.

Desulfurization process

A sorbent composition is provided which can be used in the desulfurization of a hydrocarbon-containing fluid such as cracked gasoline or diesel fuel. The sorbent composition contains a support component and a promoter component with the promoter component being present as a skin on the support component. Such sorbent composition is prepared by a process of impregnating a support component with a promoter component, wherein the promoter component has been melted under a melting condition, followed by drying, calcining, and reducing to thereby provide the sorbent composition.

Desulfurization and novel sorbents for same

A process for removing hydrogen sulfide from a fluid stream by contacting a hydrogen sulfide-containing stream with a sorbent composition wherein said sorbent composition is produced by mixing at least one zinc component which is zinc oxide or a compound convertible to zinc oxide, at least one silica component where the silica component comprises silica or a compound convertible to silica, at least one colloidal metal oxide, and optionally at least one pore generator component so as to form a mixture, extruding the mixture, sphering the resulting extrudate to form spherical particles having a size of form about 0.5 to about 15 millimeters drying the resulting spherical particles, calcining the dried particles, steaming the resulting calcined particles, sulfiding the steamed particles by contacting them with sulfides or sulfur at a temperature of about 200&deg; C. to 1400&deg; C. and subjecting the sulfided particles to a temperature sufficient to bum off substantially all of the sulfur on the sulfided particle so as to provide a sorbent composition having improved attrition and crush strength and which is then useful for the desulfurization of hydrogen sulfide-containing fluid stream.

Sorbent compositions

A novel circulatable sorbent material suitable for use in a transport desulfurization system for removing sulfur from a fluid stream containing sulfur and the use thereof in such a transport desulfurization system. The transport desulfurization process utilizes a circulatable particulate material containing alumina, silica, zinc oxide and a metal oxide which is contacted with a fluid stream and thereafter separated and reused with a portion being regenerated.

A process to produce a sorbent is provided. This process comprises: mixing a composition that comprises silica, a composition that comprises metal oxide, and a composition that comprises zinc oxide, to form a first mixture; and sphering said first mixture to form particles having a diameter from about 10 micrometers to about 1000 micrometers.

A novel method of producing an absorption composition is described where the steps include the formation of a composition comprising zinc oxide, zinc phosphate and, optionally, alumina.

Process for removing sulfur compounds

An apparatus and method for determining the level of material within a rotating cylindrical vessel are disclosed in which a rigid member means on the interior of the rotating vessel is fixedly secured to a rod having a longitudinal axis parallel to the rotational axis of the rotating vessel, and wherein the rod extends through one end wall of the vessle to the exterior at which it is fixedly secured to an indicator means. The rigid member means within the vessel is capable of resting at the top surface of the material within the vessel. As the level of material within the vessel is raised or lowered the rigid member means will rotate, thus causing an equal rotation of the rod and the indicator means on the exterior of the vessel. By monitoring the position of the indicator means, the level of material within the vessel can be determined.
