초록 ▼

The method and apparatus of the present invention are directed to conditioning particulate-containing gas streams using novel additives. The additive is an organometallic salt, preferably of a carboxylic acid, that decomposes in the gas stream to produce mobile metal compounds that significantly reduce the resistivity of the particles. The additive is particularly effective under hot-side conditions when used to condition particles to be collected by an electrostatic precipitator.

대표청구항 ▼

[ What is claimed is:] [1.]1. A process for removing undesired solid particles from a gas stream containing undesired solid particles, comprising:contacting a composition with the gas stream, the composition comprising an organometallic compound having a thermal decomposition temperature that is less than the temperature of the gas stream wherein a metal in the organometallic compound is monovalent;collecting on at least one collection surface in a particulate collection zone a solid agglomerate including at least a portion of the composition or a derivative thereof and at least most of the undesired solid particles in the gas stream, wherein the at least one collection surface is at least one electrode and the at least a portion of the composition or a derivative thereof alters the resistivity of at least most of the undesired particles collected on the at least one collection surface; andremoving the agglomerate from the at least one collection surface. [17.]17. An additive for improving charge conduction in electrostatically collected undesired solid particles under hot-side conditions, comprising:(a) at least about 0.1% by weight of a metal salt of a caboxylic acid;(b) a vaporizable carrier fluid; and(c) a decomposition agent to cause decomposition of the metal salt after contact of the metal salt with the gas stream, wherein the metal salt or a derivative thereof alters the resistivity of the electrostatically collected undesired solid particles.18. The additive of claim 17, wherein the metal salt has a thermal decomposition temperature ranging from about 260 to about 480.degree. C.19. The additive of claim 17, wherein the additive includes from about 0.1 to about 50% by weight of the metal salt. [32.]32. A system for removing undesired solid particles from a gas stream containing undesired solid particles, comprising:a housing;an input for introducing an input gas stream into the house;an output for removing an output gas stream from the housing;an additive contacting means for contacting with the input gas stream a composition including an organometallic compound having a thermal decomposition temperature less than the temperature of the gas stream and wherein a metal in the organometallic compound is manovalent; andan electrostatic collection surface positioned in the housing between the input and the output to collect on the collection surface at least a portion of the undesired solid particles and at least a portion of the composition contacted with the input gas stream or a derivative thereof and wherein the organometallic compound or a derivative thereof alters the resistivity of the undesired solid particles collected on the collection surface.
