Apparatus for treating fluids flowing at high velocity, for mass and heat transfer, for gas-liquid contacting and for contaminant particulate, mist or fume separation, including a plurality of perforated or unperforated cylinders arrayed staggered in rows perpendicular to the direction of flow of the fluid. The elements are spatially separated from each other. Diagonal by-pass flow through the array is blocked by a partition extending from each element generally parallel to the direction of flow of fluid bisecting the space between a pair of elements of an adjacent row with the elements of the pair symmetrically spaced with respect to the partition. Also, a method of removing contaminants from gas by passing the gas through this array between and injecting a liquid into the array. Capture of the contaminants by the drops is effected because of the difference in acceleration of each as the contaminated gas passes in and out of the gap between each cylinder and its adjacent partitions. Also, mass interchange between a gas transmitted upwardly through the array and liquid injected into the gas. Stable dynamic bubbling within perforated cylinders of the array takes place producing the interchange. After the gas passes through an array, it is expanded so that its velocity is reduced and it sheds drops of liquid.

The method of removing particulate from a gas with apparatus including a plurality of cylindrical elements, each said element being imperforate to said gas, said elements being arrayed in rows with the elements of adjacent rows staggered with respect to each other[,]and with each element physically separate from the elements of its row and from the elements in adjacent rows, and with partitions extending between the elements of alternate rows, each said partition being substantially in contact with the surfaces of the elements between which it extends along the length of said [each element to prevent]elements between which it extends, said partitions preventing diagonal by-pass flow through said rows, each of said partitions being interposed between a pair of elements of rows intermediate said alternate rows, there being no row from the surfaces of whose said elements more than one said partition extends, each element of a said pair and its adjacent partitions defining channels for the flow of gas, each channel being bounded by the continuous curvilinear surface of a said [cylindrical]each element of a said pair and a said adjacent partition, each said channel decreasing gradually in width from a first distance constituting a part of the distance between a pair of adjacent of said adjacent partitions to a second substantially smaller distance between said each element of said pair and one of said adjacent partitions and then gradually increasing in width from said smaller distance to a distance constituting a part of the distance between said adjacent partitions, the said first distance and the said second distance being so related [to]that an effective venturi effect for a gas flowing through said each channel is present; the said method comprising injecting a liquid into said gas to produce drops of liquid in said gas, [passing]said liquid drops, gas and particulate forming a fluid, passing said fluid through said channels defined by said rows of elements and their associated partitions generally transverse to said rows thereby to accelerate said drops of the liquid[, ]passing through said each channel from the region of said first distance through the region of said second distance, at a lower rate than the particulate passing from the region of said first distance through the region of said second distance is accelerated, whereby said liquid drops are at a lower velocity than said particulate and said particulate collides with said drops and is captured by its collision with said drops. A mist eliminator for eliminating mist from a mist-laden gas flowing in a generally horizontal direction; said mist eliminator including separate elongated cylindrical elements each positioned with its long axis generally vertically in a plurality of rows forming an array into which said fluid is to be injected, each said element being non-reentrant on its upstream side with respect to the direction of flow of said gas, the elements of adjacent rows being staggered with respect to each other, the elements in each row being spatially separate from each other and from the elements of adjacent rows so that an open flow space would normally surround each element, whereby there would normally undesirably be bypass channels permitting bypass flow for said gas at an angle to the horizontal direction in which said gas is injected into said array; the said mist eliminator being characterized by that said bypass flow of said gas is suppressed by partitions bridging between at least a plurality of pairs of certain of said elements, the elements of each of said bridged pair being in alternate rows of said array, and the elements in the intervening rows being positioned generally symmetrically with respect to said partitions, said partitions being substantially in contact with the elements which they bridge along the lengths of said elements to interpose substantially complete obstruction to said bypass flow, there being no row from the surfaces of whose said elements more than one said partition extends, said partitions being positioned generally parallel to the direction of flow of said gas as it is injected in said array and being so shaped as to minimize the pressure drop of the gas flowing through said mist eliminator.
