A method for removing contaminants from an process stream that includes the use of reticulated material to filter the process stream. The reticulated material also facilitate process stream flow distribution in process units. The reticulated material can be packed with a void space between a substantial number of the reticulated material that can be varied to enhance filtration and flow distribution. The method of filtering also provides a method of removing contaminants leaving process equipment. The methods can be used on a variety of process streams and process equipment. The reticulated material can include ceramics, metallic materials, and chemical vapor deposition elements. The reticulated material can be of various shapes and sizes, and can also be catalytically active.
A process unit assembly comprising a process unit having a plurality of reticulated elements disposed therewithin, the reticulated elements having a plurality of web members formed therein that define a plurality of flow passageways through the reticulated elements and a size such that there is a significant and varied void space between the reticulated elements in the process unit, the reticulated elements being capable of receiving a contaminated process stream on a surface thereof and enhancing filtration of contaminants from the contaminated process stream to produce a substantially decontaminated process stream when the contaminated process stream passes through the flow passageways and the significant and varied void space, wherein the process unit contains a bed of catalyst material, and wherein the pressure drop within the process vessel remains low for a predictable period of time based on the level of contaminants in the process stream and the amount of the reticulated elements provided in the process unit, and wherein the reticulated elements in the process unit are provided in an amount such that during operations, the bed of catalyst material can be exhausted before the reticulated elements are saturated, and wherein the reticulated elements are randomly packed in one or more uninterrupted layers within the process unit.
A process unit assembly comprising a process unit having a plurality of randomly packed reticulated elements disposed therewithin, the reticulated elements having a plurality of web members formed therein that define a plurality of flow passageways through the reticulated elements and a size such that there is a significant and varied void space between the randomly packed reticulated elements in the process unit, the reticulated elements being capable of receiving a contaminated process stream on a surface thereof and enhancing filtration of contaminants from the contaminated process stream to produce a substantially decontaminated process stream when the contaminated process stream passes through the flow passageways and the significant and varied void space, wherein the process unit contains a bed of catalyst material, and wherein the pressure drop within the process vessel remains low for a predictable period of time based on the level of contaminants in the process stream and the amount of the reticulated elements provided in the process unit, and wherein the randomly packed reticulated elements in the process unit are provided in an amount such that during operations, the bed of catalyst material can be exhausted before the reticulated elements are saturated, and wherein the reticulated elements have an internal surface area and an outer surface area, and the internal surface area is larger than the outer surface area, and wherein the reticulated elements have a pore size in the range of about 2.5 millimeters to about 100 microns, and wherein the randomly packed reticulated elements are capable of filtering contaminants from the contaminated process stream down to about 1 micron in size.
