An air sparger assembly for a flue gas desulfurization wet scrubber agitation tank that eliminates the need for a mixer and reduces the amount of piping required. The air sparge pipes are arranged to be concentric with the agitation tank. A single main header provides air to the air sparge pipes. The discrete location of the air discharge holes in the sparge …

3. Ring sparger: These are placed at the bottom of the bioreactor and utilize a ring-shaped structure to produce bubbles and provide oxygen transfer. 4. Micro-bubble Sparger: These are designed to produce small bubbles that provide high oxygen transfer efficiency and are widely used in large-scale, high-density bioreactors. 5.

Figure 10 Cross-section of SlamJet sparger nozzle Figure 11 Gas discharge of injection sparger A relatively new approach to increasing DO levels in leach circuits has been to use sparging systems external to the tank. Either by aeration (or oxidation) of the feed (Figure 12) or a recirculated stream (Figure 13).

The sparger is an important accessory of bubble column reactors which governs the performance of the reactor. Specifically the sparger design becomes more important when the aspect ratio of the bubble column is low. The maldistribution and design of the sparger are of major concern and both these aspects are described in detail in the …

3. Sparger; 4. Mixer's lower drive; 5. Heaters. Height-to-diameter ratio (Aspect ratio). The height-to-diameter ratio is also a critical factor in vessel design. Although a symmetrical vessel maximizes the volume per material used and results in a height-to-diameter ratio of one, most vessels are designed with higher ratio.

Different types of sparger design have been studied in the literature to determine the hydrodynamics and mass transfer properties, such as tree sparger, ring …

Abstract Bubble size has a key role in gas holdup and mass transfer in bubble column reactors. In order to have small and uniform bubbles, a new structure was designed; the reactor operates in two modes, with vibrating sparger and conventional bubble column in which sparger is fixed. In vibrating mode, the sparger vibrates gently during gas …

PROBLEM TO BE SOLVED: To provide a sparger in which the number, size or the like of through-holes can be easily customized.SOLUTION: A sparger 50 has: a flexible tube 10 having a plurality of through-holes 21; and hard connectors 42, 43, 44 connected to the flexible tube 10. The flexible tube 10 has a pair of end parts 10A, 10B and is formed in a …

The gas phase is introduced the column through a fine pore sparger, namely a 316 L SS porous disk (Mott Corp.®) with a nominal pore size of 40 μm or 100 μm, that covers the whole bottom plate. The effect of the sparger to column diameter rati o on the bubble column performance has been inves-tigated and discussed in a previous paper [7].

Table 2 lists the relevant details. Spargers A, B and D have holes covering the whole plate, and sparger C is the modification of sparger A by blocking the holes in the outer area and leaving central ones untouched [see Fig. 1(a)]. The bubbling area of sparger C is approximately equal to that of the draft tube inserted in the bubble column.

You may discover that a standard sparger is sufficient for your needs, but if your application requires a custom designed sparger, simply follow these five steps. Step #1: Outline …

In a pilot-scale internal loop airlift reactor with a height of 5.5 m and a main column diameter of 0.484 m, the influence of three gas sparger structures (ladder distributor, tri-nozzle sparger and perforated plate) on the volumetric mass transfer coefficient kLa was investigated. It was found that the perforated plate produces the …

following components: 1. A gas inlet is a connection through which the gas is introduced into the sparger. 2. A porous medium: This material allows the gas to pass through but retains the liquid. The porous medium is typically made of a material such as sintered stainless steel, ceramic, or plastic. 3.

A vacuum breaker will likely be required. There is a rule of thumb, which is also referred to as the "rule of eights". With an 8 psi differential pressure, a 1/8" diameter hole will pass about 8 lb/hr of steam. The metric equivalent is: At 1.6 bar, 1.6 mm diameter hole will pass 1.6 kg/hr steam. katmar (Chemical) 15 Dec 08 03:51.
