The lining options for vessels have been described in Ch. 4 and reproduced here to aid our discussion. The selection of lining technology depends on several factors such as chemical resistance, material availability, vessel size, heat transfer consideration, shop versus field application, and cost (Tables... 

Monel and lined carbon steel are standard materials of construction for filter vessels. Linings are similar to those used in primary filters. Figure 7.60 shows a typical vertical-tank vertical-leaf filter. The stream to be filtered enters the body of the tank. A bottom connection is shown, but there are other options. The leaves are arranged vertically, and flow is from the outside to the inside of the leaves. Filtrate collects in a pipe at the bottom this also serves as support for the filter elements. The tank also has drain, vent, and compressed air connections. The detail shows one type of assembly that can simply be lifted from the effluent pipe. O-rings supply the seals. 

Dump the reactor contents into a vessel which contains cold diluent. This option also requires particular care that the dumping line is not blocked or does not become blocked during the dumping procedure. 

With older vessels requiring repairs, one has to make a judgment as to how to repair the vessel. Basically, there are two options for repair. One is to use a chemically curable lining that is appropriate to match the lining in the vessel. Chemical cure linings may have high leech-able sulfite levels, even when cured with steam. Therefore, chemical cure linings are only considered acceptable on minor repairs. 

This was achieved using die Quest 205 apparatus from Argonaut Technologies (Basel, Switzerland). Combination of parallel syndiesis with online work-up and sample collection allows synthesis procedures using one single instrument. Each reaction vessel has a port at the top, a drain valve at the bottom and inert gas to control draining time. This gives a number of options for on-line work-up such as liquid-liquid exfraction or solvent evaporation. 

According to the obtained results diverse options can follow, including refractory proposals for field trials, executed on customer s site. This leads to an improved lining life in the vessel entailing technical and economical benefits. 

Line placement for monitoring and medication in peripheral or central venous or arterial locations is often challenging. Numerous previous surgeries, preexisting fistulae, failed cannulation attempts, hematoma, venous collapse after hemodialysis, thrombotic vessel occlusion or the presence of ClEDs in central veins reduce options and prolong preparation time. 

Contact Adhesives. Nowadays, rubber solutions based on natural rubber or styrene-butadiene rubber, optionally in conjunction with regenerate and depolymerized rubber, are used for large-area bonding where adhesion does not have to meet stringent requirements, as is the case, for example, with the lining of vessels, containers, etc. with rubber. 

Although there are numerous options for simulating the fluid flow inside a stirred tank, the goal of the simulation is to learn about the various aspects of the flow field. On a simple level, this might include velocity vectors in one or more regions, path lines followed by infinitesimal fluid elements as they wind their way through the vessel, or the distribution of a tracer species after some period of time has passed, for example. On another level, the analyst might want to...
