<strong>Tray</strong> Selection<br />
Product Bulletin-400<br />
Page 5<br />
<strong>Tray</strong> type selection is generally accomplished by balancing various process <strong>and</strong> mechanical<br />
consi<strong>de</strong>rations. Major mechanical <strong>and</strong> process factors taken into consi<strong>de</strong>ration inclu<strong>de</strong> capacity,<br />
efficiency, turndown, pressure drop, susceptibility to corrosion <strong>and</strong> fouling, <strong>and</strong> actual experience in the<br />
system.<br />
What may be an overriding consi<strong>de</strong>ration in one case may be unimportant in another; therefore,<br />
each situation must be examined on its own merits. With the exception of special licensed tray<br />
technologies, <strong>Raschig</strong> Jaeger has the capability to produce virtually any type of conventional or specialty<br />
tray type<br />

<strong>Raschig</strong> Jaeger trays can be fabricated from numerous types of materials. In addition to working<br />
with the most common carbon, ferritic, <strong>and</strong> austenitic steels, we also work with many exotic materials<br />
such as Hastelloy® alloys, titanium <strong>and</strong> specialty duplex stainless steels. A brief listing of acceptable<br />
materials of construction inclu<strong>de</strong>:<br />
